Predatory nematode nemabact harm and benefits on potatoes

Unfortunately, after a short time, insect pests acquired persistent immunity to toxic chemicals, and this gave rise to even more toxic pesticides. This process continues in the XXI century. Naturally, it cannot be infinite. By the mid-twentieth century, biological methods for the control of insects, pests based on bacteria, fungi and worms, were developing abroad and in Russia. Today, parasitic roundworms - entomopathogenic nematodes - of the genera Steinermena and Heterorhabditis are one of the most effective types of biological control available for widespread use.

1.2. Entomopathogenic nematodes

The peculiarity and attractiveness of entomopathogenic nematodes is their active search for insect prey, suppression of immunity in the affected insect, high parasite efficacy against insect pests (60-100% die) after a single application, the remaining living individuals will be affected later. Insects in the population do not develop immunity against nematodes.

Another distinctive feature is that ESP-based preparations are harmless to humans and domestic animals, bees, fish, earthworms, and beneficial insects. Because EPN has no effect on people, no special precautions or protective clothing are required.

Nematode - what is it?

Even those who are far from gardening and horticulture, have often heard complaints that the nematode is the culprit of many problems with the harvest. From the school course of biology, we can recall that nematodes are a certain class of roundworms, of which there are more than two dozen, and maybe more. These worms are parasites of plants, animals and humans. It is necessary to get rid of them radically, because they feed on their masters. Interestingly, these parasitic worms live on land, in fresh and salt water. The largest nematode worm is found in the body of the whale, and its length reaches almost 8 and a half meters! Also this type of worms is divided according to the signs, where they live and what they eat. Plant-eating nematode worms harm plants, especially cultivated ones, for which a person cares, waters, loosens the soil, because the larvae of these pests live and develop in the soil. But there are nematodes that parasitize on their fellows and on the larvae of other insects. It was on this group of nematodes that scientists decided to test the possibility of creating a bioinsecticide. The result of this research work was the drug "Nemabakt."

Plants and nematodes

For the garden and garden plants, the nematode is as big a problem as this worm that lives in the whale's body. If a plant is infected with a plant nematode, then it develops poorly and grows. Since the parasite harms the roots, splitting them, allowing them to get inside the fungi, bacteria. In addition, the small roots of plants die off, and the root itself thickens, splits, becomes sick. The plant is sick and bad fruits. That is why nematode worms are the enemies of plants and harvest in the first place. But on the use of this pest based drug "Nemabakt", reviews of which leave gardeners and gardeners, protecting the crop.

Alien among his

So what is the drug "Nemabakt." Its composition can be called unusual for the usual insecticides. After all, the main component of this plant protection product is a nematode. Yes, scientists have more than a decade of use of entomopathogenic nematode worms in the fight against relatives. How so? The drug "Nemabakt" as an active ingredient contains nematodes infected with a symbiotic bacterium. Worms settle in the ground, they begin to lead a normal life for themselves, but infecting their relatives, who eventually die. But what are symbiotic bacteria? And this is a special type of microorganisms that live in a single inseparable community with insect pests, worms that destroy plants. The bacterium settles in the larvae of insects, in beetles, worms and feeds on its host, causing its death. The nematodes populated in the ground themselves also parasitize in the larvae of various insects living in the ground. So the drug "Nemabakt" appointment is special - without harming nature, destroy pests.

Who is fighting "Nemabakt"?

If on the garden, dacha site of the plant began to feel bad, then certainly some kind of parasites or diseases are to blame. For an experienced gardener will not be difficult to determine what kind of attack hit your favorite garden beds, flower gardens or garden. If this is not a disease, then it is “Nemabakt”, instructions for use, reviews of which tell about the fight against insect pests, will help to cope with the problem on the site. The pests themselves, of course, will not disappear, to poison the land with pesticides - to harm themselves and nature. Therefore, many gardeners are already using "Nemabakt", expressing mostly positive reviews about it. It is noteworthy that the tool "Nemabakt" was developed jointly with the All-Russian Research Institute of Plant Protection, which is located in the city of Pushkin, Leningrad Region, and is produced by several Russian companies. So, the use of a preparation containing an active component of entomopathogenic nematodes in pest control has a serious scientific substantiation. Who does Nemabakt fight with? Reviews of those who have already used it on their beds and flower beds, talk about the many pests that we managed to get rid of. The larvae of most pests develop in the ground. It is there that the entomopathogenic nematode, which the Nemabact preparation contains, finds. Instructions for use of the tool tells you what problems it helps to get rid of:

  • Colorado beetle,
  • wireworm (larvae of the click beetle),
  • thrips (california and flower),
  • scoop cabbage
  • weevil,
  • mosquito mushroom,
  • leafworm,
  • carrot fly
  • May pickle,
  • bark beetle
  • Medvedka,
  • currant glass,
  • sea ​​buckthorn fly

One interesting feature is observed for the predatory nematode: it hibernates when it becomes cold, and with the onset of heat it starts to work again, clearing the ground from pests and protecting the crop.

Nemabak: for

The preparation containing an entomopathogenic nematode as an active component in pest control is a unique remedy among insecticides. It uses natural resources to treat nature itself, or rather, a specific place where people grow vegetables, berries, fruits, flowers. The advantages of the drug "Nemabakt", the instructions for which contains basic information about the tool, are as follows:

  • the drug is absolutely harmless to living beings - people, domestic and wild animals, bees, even aquarium fish (you never know!) will not suffer from its action,
  • bioinsecticide "Nemabakt", the manufacturer guarantees it, is valid for two years while observing the rules of using the product - that is, having treated the land once with this preparation, you can forget about pests for two years,
  • entomopathogenic nematode kills pests at the larva stage, so they do not have time to harm the plants.

Producers of the facility announce it as a bioinsecticide that does not harm nature and all living things, helping to get rid of pest larvae on a specific patch of soil.

"Nemabakt": against

Before using any new product you should study it well. The same should be done by acquiring the biological product "Nemabakt"? Instructions, reviews about him suggest several questions. For example, why do only the larvae of garden pests die? Beneficial inhabitants of the soil, such as earthworms, for example, must also suffer from entomopathogenic nematodes and symbiotic bacteria. In addition, plants on the soil surface are still unprotected from the invasion of flying, jumping and crawling pests. The answer to this question remains open, although for most gardeners and gardeners, the absence of diseases planted on plants is proof of the effectiveness of the drug. The instruction also mentions that the bioinsecticide needs to be introduced on time - 2 weeks before the development of the larvae, so that the nematode can spread throughout the site and begin its fight against the larvae-pests. Well, it is necessary to protect the crop from other troubles in other ways, complementing the drug Nemabak. The side effects of bioinsecticide, we can conclude that this is a potential danger to beneficial insects, as well as inefficiency in case of lost time in the development of larvae when they are most susceptible to the negative effects of entomopathogenic nematodes.

What's the catch?

When deciding to purchase a biological insecticide "Nemabakt" for crop protection, it should be noted that there are living organisms in the package. Although they fall into a kind of anabiosis during a cold snap, they can simply dry out in a dried substrate, and die with a strong freeze. Therefore, there are features of its storage and use. Another nuance that should be taken into account if the decision on the use of the Neambact bioinsecticide is made is the impossibility of storing the finished product. This is due to the fact that an aqueous solution of the preparation is prepared for entering into the soil; during storage, nematodes settle to the bottom, and there is no oxygen there. Worms are dying. Therefore, it is impossible to prepare the solution in advance, as well as to store it. Opened packaging with the tool must be used as quickly as possible, without leaving for storage.

How to deliver?

The drug is supplied in a special soil where entomopathogenic nematodes are in a state of suspended animation - hibernation. This effect is obtained by maintaining the storage temperature of the nematode packs within 2-8 degrees Celsius. When the temperature rises, the nematodes begin to "revive". This process is the main one in transportation and preparation of biological means for use. In addition to the cold, the nematode is afraid of sunlight, ultraviolet radiation. In the sun and without moisture, it can dry. When the temperature rises during storage, the biomaterial begins to come to life, and for life, nematodes need oxygen. But since the packaging is sealed, and the nematodes came out of the state of anabiosis with increasing temperature, they simply die without oxygen. So during transportation and during storage of bioinsecticide one should strictly observe the temperature conditions, as well as protect the biomaterial from the neighborhood with chemical insecticides and poisons.

How to use?

One of the non-chemical insecticidal drugs is Nemabact. Its application should be strictly in accordance with the instructions. So, before using the package of the drug must be deployed and allow the soil to warm up in natural conditions, but not reaching a temperature of more than 26 degrees Celsius. Usually, the biomaterial is heated to ambient temperature in 6-8 hours. In order to ensure the activity of nematodes, you should use a magnifying glass with an increase of not less than 20 times. Active worms should be in sight, although in the preparation there are already dead individuals. If the drug is active, then it is diluted with ordinary water of natural temperature in a bucket. The ratio of means and water should not be less than 1: 100, otherwise the nematode will multiply for a very long time and will have no effect from it. The drug is introduced into the ground by spraying or watering. It is not necessary to pour water with the product so that it falls on the leaves of the plants - the nematodes will die under the sun or simply dry out in the open air, and there will be no benefit from them, the money will be spent in vain. Bioinsecticide can be applied using mechanical or electrical sprayers, but nets must first be removed from the nozzles so that nematodes do not get stuck in the cells, despite their microscopic dimensions, and are not damaged by the mesh contours when passing through it. When applying the drug to the soil, periodically shake the container with water so that the biomaterial does not settle on the bottom, but evenly distribute. Another prerequisite for the effective use of the drug "Nemabakt" is the moistening and loosening of the soil before introducing into it a bioinsecticide. This will allow the nematodes to quickly penetrate into the depth, moreover, so favorable conditions will be created for their livelihoods - a moist, loose soil with active access of oxygen. It is possible to repeat the irrigation with a pest control in 1 hour, and to moisten the soil to create favorable conditions for the preparation to work half an hour after the second application.

Is there an alternative?

Plant protection from a variety of pests and diseases - the main task of those who grow crops, cares for forests and fields. In the arsenal of agriculture and household gardening, many various means of helping plants are used. And biological products take their rightful place in them. Bacteria, fungi, entomopathogenic organisms of the nematode type are used as active components of this group, as, for example, in the Nemabact bioinsecticide. Analogs of this drug are few. In the Russian market of such funds, you can find another such drug called Antonem-F. Many gardeners prefer to use old time-tested tools such as chemical insecticides or plant-based solutions. But often such funds do not bring benefits, but can cause significant harm to the ecological condition of the site, and thus to the crop and man. Therefore, the use of bioinsecticides attracts more and more attention, although for many they cause a lot of questions and caution in the application.

Summer residents about "Nemabakt"

The drug "Nemabakt" appeared on the shelves of Russian stores not so long ago. And among gardeners and gardeners, there are quite a few who have not heard enough about this preparation. Therefore, many of those who grow flowers, vegetables, berries, fruits in their garden plots, carefully study "Nemabakt": instructions for use, reviews become decisive arguments in deciding whether or not to use this tool in your site. It would be natural to say: "How many people, so many opinions." The same applies to the Nemabak bioinsecticide. Reviews about it are controversial, although it should be noted that many are still satisfied with this tool. Most often, you can hear some confusion about the selectivity of the drug and its absolute harmlessness to all other living beings. For example, there are isolated responses that moles have disappeared from the site treated with this bioinsecticide, which remind insects little. However, thanks to this nuance, the Nemabak product received excellent reviews, because the moles also harmed the crop. Many gardeners would like to increase the shelf life of the drug, complaining that it can not be stored. But nematode worms are living creatures, and it is simply impossible to program them for other living conditions. All those who have already used the Neumbact bioinsecticide or its analogue Antonem-F are satisfied with the absence of the nematode disease in plants. Although for many, having other problems in harvesting is a priority.But what is noted by almost all those who have already used the drug "Nemabakt" to protect plants in their dacha or household plots - a significant decrease in the total number of pests. And as a result, stable yields under good weather conditions.

Drug Nemabak reviews itself leaves controversial, although those who are grateful to the new crop bioprotection against pests are still more than skeptics or totally unhappy. Biomaterial means by definition should not harm the wildlife. Its action is based on the natural processes that a man saw and adopted in the struggle for the harvest. Of course, the fact that the active component of the drug is living organisms introduces its essential features in its use: storage and transportation conditions, the inability to harvest the solution for future use, the need to respect the temperature, loosening and watering the soil before applying the bioinsecticide to the soil. But these efforts and cares should be rewarded by reducing the number of pests on the treated area, and thus increasing the yield. In addition, the drug is applied to the soil once every two years, so that the efforts are not so significant compared with the expected result.

Nemabak - a biological product

AT protected ground nemabak effectively acts against: Californian and flower thrips, cabbage flies, mushroom mosquitoes, crickets on peppers and vegetables, weevil.

AT open ground against: currant glass, kidney moth, wireworm, sea buckthorn fly, cabbage fly, leafworm, fruit moth, May Khrushchev, Shchelkuna, Medvedka, Colorado potato beetle, bark beetle, May beetle and, as an additional effect, moles leave the treated areas.

The drug is harmless to humans and domestic animals, bees, fish, earthworms, beneficial insects.

"Nemabakt"- The symbiosis of a predatory nematode and a bacterium that penetrates inside the insect larva, literally eats it from the inside, after which it leaves the empty shell.

An entomopathogenic (or insect-parasitic) nematode (EPN) is a round microscopic worm. Lives in the soil.

It penetrates into the larva through its natural openings (for example, through the spiracle) and together with the highly pathogenic bacterium for insects, which lives in symbiosis with EPN, kills this larva within 24 to 72 hours.

A few days later, thousands (hundreds of thousands) of new nematodes leave the insect's corpse and begin to search for new victims.

For the winter period, the nematode “falls asleep”, in the spring it “wakes up” and the period of searching for the source of food - the insect larvae - begins again.

Extract of the drug after storage and transportation:

The conditions of storage and transportation of the drug differ from the usual conditions of the nematode. Therefore, it falls into an anabiosis state — it becomes immobile. In this state, it can not be used, because on the surface of the soil, it will quickly die (dry).

The preparation should naturally (without forced heating) warm up to the ambient temperature, but not more than 26 ° C. Typically, the exposure of the drug ranges from 2 to 4 hours (recommended 8 hours). At the same time, the nematode gradually goes out of the anabiotic state, begins to move.

Now she is able to quickly penetrate into the soil after application.

Control of drug readiness for use:

It is recommended to carry out the control both at the stage of holding the preparation and after diluting the preparation. For control, you will need, for example, a microscope or a magnifying glass with a magnification of 20 (it is enough to make sure that a nematode is in the field of view of the microscope).

In the field of view of the microscope, one can observe motile nematodes (they can quickly or slowly move and move) and motionless. Dead nematodes are necessarily present in the preparation, most often they have an elongated straight shape. Over time, during storage, their number increases.

Live nematodes can also be stationary, however, if disturbed, they begin to stir.

Optimal conditions for the use of the drug:

It is necessary to make the drug in the soil in the morning or evening (in the absence of direct sunlight) or during the day in cloudy or rainy weather. The ambient temperature should be in the range of +10 ... + 26 ° C, high humidity is desirable.

The introduction of nemabakta in the soil:

Observe the requirements for the equipment used. Lack of a grid when watering.

When introducing the drug into the soil, it must be remembered that the equipment must comply with work with living organisms, if a pump is used, the pressure should not exceed 4 atmospheres, the rotating filter grids of the spray nozzles of irrigation units and systems should be removed.

When making the drug output equipment nozzles should be kept near the soil surface. It is necessary, if possible, to exclude the ingress of the drug on the leaves of plants, because on the leaves the nematode dies (dries out). For processing small areas you can use a watering can.

Features and instructions for use of the drug Nemabakt

When tillage, it is important that the solution is applied at night. For a protective bandage this is unprincipled.

In the spring, the Nemabak project staff advised to hang protective erection bands impregnated with EPN-preparation on trees and to shed tree trunks. Wrap the wrap so that the bandage stays wet longer and secure with wire.

As I understand it, the addition of vermiculite to the upper layer is possible, together with the surface (5-7 cm) loosening, and this does not increase the work effort.

ru very interested drug Nemabakt, with social networks is not very friendly.

They are used according to the instructions. Such drugs require compliance with the methods of precaution described in the instructions. Observe the requirements for the equipment used.

When using chemical and biological preparations for pest control, you should carefully read the instructions for use and follow all the recommendations indicated in the annotations. Dilute the prepared solution in accordance with the recommendations of the table from the instructions.

So, you are ready to test the drug in action. In this case, you need to get acquainted with the rules of the use of "Nemabakta".

This concept is fully consistent with the policy of LLC “Albin“ Podvorye ”, which in its activity pays special attention to organic farming. The unique development of the Compound ALBIN LLC is the Zashchita soil. To begin with, I’ll give the words of the honored and respected gardener Galina Kizima: The Moscow company "Compound Albin" released several different soils for sale.

Application technology depends on the phase of plant development. You can apply in any phase of plant development. It can be used in integrated plant protection, in the system of alternation of chemical and biological agents.

The optimal ratio of two species of nematodes, providing an increase in biological efficiency of 20-22.3%, are the concentrations, respectively, 80 thousand and 60 thousand nematodes / plant.

ESP drugs can be used in an integrated plant protection system with chemicals when you need to take urgent measures to treat already heavily infected plants.

Nematodes against soil insects

Glyocladin. Analogue of Trichodermin, intended against root rot, especially effective on cucumbers.

It is used for presowing treatment of cereal seeds with low pathogen pathogens, for the treatment of potato tubers and spraying during the growing season.

It acts on the carrot leafs, causing a strong twisting and twisting of carrot plants, especially near coniferous forests, from which it flies to umbrella cultures.

If summer is hot, potatoes need to be cleaned in a timely manner, as the delay leads to roasting of the tubers in the ground, causing them to rot within 14 days after digging. If the summer is rainy, the potatoes are also harvested just in time, otherwise it can sprout. We have a lot of it, in autumn, almost all the potatoes are bitten, and in spring it gnaws young seedlings.

In the experimental variants, the insects flew out in single copies without a definite pattern. The main danger of the pest is that adults can fly over long distances, overcome water obstacles and adapt well to new conditions of existence.

It is, of course, about the various types of insects, which sometimes destroy entire yields. When an egg-laying pest is stretched, two treatments are usually carried out with an interval of 7–10 days against each generation.

The wire was still there, since the drug does not guarantee 100% of deliverance, but a regularity emerged: the most wireworms were around the perimeter of the vegetable garden - that is, the very first bed.

This is almost the entire list of microbiological preparations that can be used to control pests. With their help, the problem of combating insects with pests, against which practically no other effective remedies are practically absent, is solved. At present, there are no effective measures to combat this pest in ornamental cultures.

The main feature of these remedies is their harmlessness to humans, the environment, domestic and wild animals, insects (pollinators, entomophages) and other representatives of the biocenosis. Preparations using EPN are absolutely harmless to humans, domestic animals, bees, fish, earthworms, and beneficial insects. It is very difficult to combat soil-threatening insect species.

When a pest appears in a garden or in a garden, most people wonder how to get rid of a medvedka by folk remedies, because they are simple, accessible and environmentally friendly. Summer residents often wonder how to get rid of the darlings in their summer cottage and not harm the beneficial insects and other inhabitants.

The conditions of storage and transportation of the drug differ from the usual conditions of the nematode. The effectiveness of nematodes in the tested consumption rates did not differ significantly, however, with a lower dose (250 thousand

nematodes) the departure of individuals of insects was observed over a longer period.

One of the main activities is the production of Nemabak® and Antonem-F® preparations made on the basis of entomopathogenic nematodes.

Nemabact is available for sale.

NEMABAKT is used on ornamental crops against furrowed skosar, on currants against currants glass bowl, on cabbage against cabbage flies, on potatoes against wireworms and Colorado potato beetle larvae.

ENTHONEM-F The main application of this drug is the Colorado potato beetle and wireworm on potatoes, western flower thrips and furrow cutter on ornamental crops, currant steamer on glass case, sea buckthorn fly on sea buckthorn, mushroom flies on champignons and cabbage flies on cabbage.

Cost: 750 rubles. Acquire at our stores.
✅ Additional information.

According to the results of State tests (1993-2003).

The biological effectiveness of the preparations against the following types of insect pests of agriculture was established: thrips - 86-98%, crickets on the 4th day - 77.9% and on the 30th day - 100%, mining flies - 80-90%, weevils - 64-100 %), on mushrooms against mushroom mosquitoes - 60-90%, wireworms on potatoes and corn - 97.9%, cabbage flies - 60-90%, apple and plum moths - 80-100%, Colorado potato beetle larvae - 80%. cherry fly - 85%, sea buckthorn fly 93-100%.

In agriculture, as well as other areas of the national economy, systems of measures are being developed in which ecological methods are becoming the main methods for reducing the number of pests, which promote reproduction and increase the activity of natural enemies - parasites, predators, and pathogens. In this regard, in the last two decades, interest in entomopathogenic nematodes from the Steinernematidae and Heterorhabditide families has increased, which can be used as a means of combating insects - pests of agricultural crops.

The soil is the natural habitat of these nematodes, where they are well adapted to different conditions of humidity, temperature, mechanical and chemical composition of various soil types, therefore, steinnernematids and heterorabditids are found on all continents except Antarctica and in almost all latitudes and altitudes above sea level.

These parasites are able to infect more than a thousand species of insects from various orders, affecting all phases of development, except eggs. Invasive larvae of nematodes penetrate into the body of the insect passively with food and actively through the mouth, anus, spiracle and cuticle, after which the nematodes release into the blood of an insect symbiotic bacteria of the genus Xenorhabdus.

After infection with nematodes, the insect dies for 2-3 days under the action of symbiotic bacteria and as a result of damage to the internal organs by nematodes. Entomonematodes reproduce well in insects, they can be applied by conventional methods, remaining in the soil, they can exist for a long time without food in the absence of the host insect.

Resistance to many modern pesticides and the absence of pathogenic effects on plants, earthworms and vertebrates allows them to be effectively used in pest control programs.

Hundreds of researchers in approximately 80 university, government and industrial laboratories in forty countries work with entomopathogenic nematodes. Biological preparations based on nematodes for commercial purposes are produced on 4 continents and are successfully used against soil pests, and their use is becoming increasingly important.

These drugs can be used in conjunction with chemical and biological plant protection products. Currently, in the USA, Canada and European countries, 83 companies are engaged in the production, wholesale and retail sales of entomopathogenic nematodes.

As a result of 40 years of scientific research on the study of the characteristics of biology, the development of production technologies, the use and creation of biological products based on entomopathogenic nematodes, two biological preparations based on entomopathogenic nematodes, ENTONEH-F and NEMABACT, were created and registered in the Russian Federation

These drugs are environmentally friendly and completely safe for plants, warm-blooded animals and humans.

"Nemabakt": what is this drug and who is afraid of him

The main weapon of the bioinsecticide "Nemabakt" is a predatory nematode - a microscopic roundworm, as well as a bacterium infested into it, with which they form a definite symbiosis.

The nematode penetrates the insect larva, where the bacterium eats it for several days and, in turn, provides the nematode with a source of food, the worm actively multiplies inside the larva, and then leaves the empty shell to find another insect. Nematodes multiply very quickly and begin to look for new sources of food, that is, insect larvae. Nematodes settled on a piece of land continue to clear it for two or three years, at the end of autumn they hibernate, and in the spring they become active again.

The drug "Nemabakt" according to the instructions used vs:

  • California thrips,
  • flower thrips,
  • mushroom mosquito,
  • cabbage fly,
  • weevil
  • crickets (on vegetable crops),
  • currant glass bowl
  • wireworm,
  • leaf wrappers,
  • kidney moth
  • sea ​​buckthorn fly
  • Colorado potato beetle
  • May beetle,
  • Bears,
  • friggin
  • bark beetle.

2. Description of the drug "Nemabakt"

EPN is a very promising basis for bioinsecticides, which has spread in a number of countries of all continents. It is most widely used in Australia, America, Asia - Japan, China, India, in Europe. The mass production of EPN drugs abroad began in the eighties of the twentieth century. In Russia, the use of ESP due to economic difficulties, despite the rather deep theoretical developments, has not yet received a decent development.

LLC "Bioranta-Chekhov" since 2001. produces and sells a biological insecticide "Nemabakt" on the basis of EPN. The drug is similar to foreign similar drugs, but more adapted for use in Russia. The drug is used in TC “Barvikha”, Mytishchi State Farm of Ornamental Horticulture, Agrofirm “Kosino”, “Zarechie them. S.A. Kushnareva ”, APC“ Voskresensky ”and others. The preparation was used and gave feedback on the farms with a positive result in combating thrips with the Californian flower, cucumber mosquito, wireworm, cabbage moth, May shrimp, carrot fly, weevil.

The effectiveness of the use of EPN depends on the moment of introduction of the drug. Each pest has its own development cycle, including the period of life in the soil. In this period of life there is a phase of pest development with maximum sensitivity to ESP. Therefore, it is advisable to use the drug no later than 1 to 2 weeks before the start of this phase, so that the nematode has the opportunity to penetrate and spread in depth into the soil. In the case of the use of the drug against several types of pests, the question of its use is more difficult to solve. It is advisable to seek the advice of specialists (paragraph 6 of this description of the use of the drug). The general approach is as follows: the drug is administered in 2 stages.

First stage. The drug is introduced into the soil to combat the pest with an earlier EPN-sensitive development phase. The concentration of the drug is maximum (based on 1 hectare of 1 hectare norm, but in case of severe contamination, the concentration should be increased by 1.5 times, and with a high sensitivity of plants to pests - by 2 - 3 times). The moment of introduction is 1 - 2 weeks before the start of the pest development phase with maximum sensitivity to ESP.

Second phase. The concentration of the drug in this case is 1 hectare 0.5 hectare. The drug is made in 5 - 6 weeks.

Practical experience shows the need to strictly observe a number of requirements when working with an ESP - drug. They are based on the fact that EPNs are living organisms that can exist in certain ranges of temperature, humidity, etc. Requirements are described in sections 3, 4 and 5.

Nematode - what is it?

Even those who are far from gardening and horticulture, have often heard complaints that the nematode is the culprit of many problems with the harvest. From the school course of biology, we can recall that nematodes are a certain class of roundworms, of which there are more than two dozen, and maybe more. These worms are parasites of plants, animals and humans. It is necessary to get rid of them radically, because they feed on their masters. Interestingly, these parasitic worms live on land, in fresh and salt water. The largest nematode worm is found in the body of the whale, and its length reaches almost 8 and a half meters! Also this type of worms is divided according to the signs, where they live and what they eat. Plant-eating nematode worms harm plants, especially cultivated ones, for which a person cares, waters, loosens the soil, because the larvae of these pests live and develop in the soil. But there are nematodes that parasitize on their fellows and on the larvae of other insects. It was on this group of nematodes that scientists decided to test the possibility of creating a bioinsecticide. The result of this research work was the drug "Nemabakt".

4. Storage conditions of the drug "Nemabakt"

When storing, observe the following conditions:

• Storage temperature: +2 ... +8 0 С (exclude freezing),

• Store away from chemical insecticides and poisons,

• Do not expose the ESP preparation to ultraviolet radiation or sunlight,

The drug is recommended to be stored no more than a week (with a lack of dissolved oxygen the nematode dies).

5. Use of the drug

5.1. Preparation of the drug for use

5.1.1. Exposure of the drug after storage and transportation

5.1.2. Dilution of the drug to the required concentration

5.1.3. Control of drug readiness for use

In the field of view of the microscope, one can observe motile nematodes (they can quickly or slowly move and move) and motionless. Dead nematodes are necessarily present in the preparation, most often they have an elongated straight shape. Over time, during storage, their number increases. Live nematodes can also be stationary, however, if disturbed, they begin to stir.

5. Use of the drug

Drug benefits

Indisputable merits drug "Nemabakt" are the following:

  1. It is harmless to humans, domestic animals, fish, bees, beneficial insects and earthworms.
  2. After a single treatment of a plot of land with a drug, nematodes continue to “work” on it for several years, while they can live in the soil for up to two years even in the absence of food (insect larvae).
  3. Worms quickly destroy pests even at the larval stage, thus minimizing the damage they can cause to plants.

Transportation

Nematodes in packaging are in anabiosis. Therefore, the tool must be transported carefully. Extract of the drug - up to 8 hours. During this time, the nematode is already starting to move and is able to quickly penetrate the soil. At temperatures up to + 28 ° C, it should be wrapped in several layers of paper, and if the temperature rises higher, bring a cooler bag with you.

Application rate "Nemabakt" and instructions for use

In online stores "Nemabakt" is expensive, but the price is justified during use.

First you need to dissolve the bioinsecticide. Pour water into buckets and place mosquito nets on the edges of the containers. After that, each bucket should be poured on the packaging of the drug. The temperature of the water must match the temperature of the soil and air.

You can check the readiness of the solution for use. For this you will need a magnifying glass with a 20x magnification. If the worms move, then the drug is ready. Bring "Nemabakt" in the morning or evening, on a cloudy or rainy day. The temperature should be up to 26 ° С, and the air humidity - 80% and higher.

As soon as you start "pouring" nematodes directly into the ground, remove the mesh.

When watering, try not to fall on the leaves of plants - nematodes left on the leaves will dry out and die. Half an hour after application, water the plant again. One bucket of the drug will be enough for 1 hundred parts of the land.

"Nemabakt" is applied to any crops where pests from the list are present, so it is worth buying and using it in your garden.

Nemabak: for

The preparation containing an entomopathogenic nematode as an active component in pest control is a unique remedy among insecticides. It uses natural resources to treat nature itself, or rather, a specific place where people grow vegetables, berries, fruits, flowers. The advantages of the drug "Nemabakt", the instructions for which contains basic information about the tool, are as follows:

  • the drug is absolutely harmless to living beings - people, domestic and wild animals, bees, even aquarium fish (you never know!) will not suffer from its action,

"Nemabakt": against

Before using any new product you should study it well. The same should be done by acquiring the biological product "Nemabakt"? Instructions, reviews about him suggest several questions. For example, why do only the larvae of garden pests die? Beneficial inhabitants of the soil, such as earthworms, for example, must also suffer from entomopathogenic nematodes and symbiotic bacteria. In addition, plants on the soil surface are still unprotected from the invasion of flying, jumping and crawling pests. The answer to this question remains open, although for most gardeners and gardeners, the absence of diseases on the planted plants confirms the effectiveness of the preparation. The instruction also mentions that the bioinsecticide needs to be introduced on time - 2 weeks before the development of the larvae, so that the nematode can spread throughout the site and begin its fight against the larvae-pests. Well, to protect the crop from other troubles should be in other ways, complementing the drug Nemabak. The side effects of bioinsecticide, we can conclude that this is a potential danger to beneficial insects, as well as inefficiency in case of lost time in the development of larvae when they are most susceptible to the negative effects of entomopathogenic nematodes.

Summer residents about "Nemabakt"

The drug "Nemabakt" appeared on the shelves of Russian stores not so long ago. And among gardeners and gardeners, there are quite a few who have not heard enough about this preparation. That is why many of those who grow flowers, vegetables, berries, fruits in their garden plots, carefully study "Nemabakt": instructions for use, reviews become decisive arguments in deciding whether or not to use this tool in your site. It will be natural to say: "How many people, so many opinions." The same applies to the bioinsecticide "H emabact." Reviews about it are controversial, although it should be noted that many are still satisfied with this tool. Most often, you can hear some confusion about the selectivity of the drug and its absolute harmlessness to all other living beings. For example, there are isolated responses that moles have disappeared from the site treated with this bioinsecticide, which remind insects little. However, thanks to this nuance means "Nemabakt" received excellent reviews, because the moles also harm the crop. Many gardeners would like to increase the shelf life of the drug, complaining that it can not be stored. But nematode worms are living creatures, and it is simply impossible to program them for other living conditions. All those who have already used the Neumbact bioinsecticide or its analogue Antonem-F are satisfied with the absence of the nematode disease in plants. Although for many, having other problems in harvesting is a priority. But what is noted by almost all those who have already used the drug "Nemabakt" to protect plants in their dacha or household plots - a significant decrease in the total number of pests. And as a result, stable yields under good weather conditions.

Drug Nemabak reviews about itself leaves controversial, although those who are grateful to a new crop bioprotection tool against pests are still more than skeptics or totally dissatisfied. Biomaterial means by definition should not harm the wildlife. Its action is based on the natural processes that a man saw and adopted in the struggle for the harvest. Of course, the fact that the active component of the drug is living organisms introduces its essential features in its use: storage and transportation conditions, the inability to harvest the solution for future use, the need to respect the temperature, loosening and watering the soil before applying the bioinsecticide to the soil. But these efforts and cares should be rewarded by reducing the number of pests on the treated area, and thus increasing the yield. In addition, the drug is applied to the soil once every two years, so that the efforts are not so significant compared with the expected result.
