Herbicide of system action for grain crops

Biathlon- herbicide of system action for grain crops

Active substance: 2,4-D acid as 2-ethylhexyl ester + triasulfuron

Chemical class: aryloxyalkanoic acid + sulfonylureas.

Concentration: 564 g / l + 750g / kg

Preparative form: emulsion concentrate, CE / water dispersible granules, EDC

Application features: The most effective application BIATHLON on actively vegetative weeds in the temperature range from + 15 ° to + 25 ° С. Maximum efficiency is achieved when processing a crop, when annual weeds are in the phase of 2-3 leaves, perennial - in the rosette phase with a diameter of up to 5 cm, perennial root-shedding species (growth types) - in the rosette-beginning of planting phase. If there is a large contamination by the bindweed field, use preparations containing dicamba esters, for example ELANT-PREMIUM, TRIATLON. It is recommended to apply on soils with pH not higher than 7.5. If it is necessary to replant in the year of use, only winter and spring wheat can be sown.

Compatibility with other pesticides:

BIATHLON can be mixed with insecticides (BARGUZIN 600, DESANT, TSUNAMI), as well as with other herbicides and fungicides used in the same time frame. For the control of cereal weeds, incl. oats in wheat crops, it is necessary to apply graminicide GRASSER. In case of severe contamination of crops with dry eel, the rate of consumption of the GRASSER should be at least 0.8 l / ha, while the recommended flow rate of the working fluid should be at least 200 l / ha. When preparing tank mixes, it is necessary to avoid direct mixing of preparations without prior dilution with water. In tank mixes BIATHLON the consumption rate of the mixture partner is selected according to the recommendations for the use of these drugs. In each case, mixable preparations should be checked for compatibility before use.

8-9 g / ha Stalker, VDG (tribenuron-methyl, 750 g / k)

2.7- 3 g / ha DUCAT, EDC (triasulfuron, 750 g / kg)

  • The combination of the three active ingredients combines all the positive properties of each of the drugs. Due to the pronounced synergistic effect between the components, the widest possible range of action against dicotyledonous weeds is achieved.
  • Due to the presence of two sulfonylureas in the composition, the period of herbicidal action is prolonged, the so-called “shielding” effect is created, which allows suppressing the second “wave” of weeds in case of its occurrence.
  • Reducing the rate of consumption of triasulfuron three times, compared with independent use, minimizes the risk of aftereffect.

Mechanism of action

2,4-D acid has hormonal activity, acting as a growth inhibitor. Penetrating through the leaves, stalks and roots, actively influences the processes of photosynthesis and cell division in the weed meristem, causing anomalous deformation of the leaves, stalks and, as a result, the death of the whole plant.

Triasulfuron and tribenuron-methyl block the synthesis of the enzyme acetolactate synthase, which is involved in the synthesis of the essential amino acids valine, leucine and isoleucine. Suppression of this enzyme blocks cell division, leads to a quick arrest of weed growth, yellowing, and then death.

Symptoms of exposure

The main symptoms of the action are: uneven growth of the aerial organs, various kinds of deformation, leaf discoloration, shortening of the internodes, redness of the veins, chlorosis of the leaves, dying of growth points, tissue necrosis.

Impact speed

The components of BIATHLON PLUS quickly enter the weed plant through the leaves and partially through the roots, actively moving in it, accumulating at the growth points. The growth of sensitive weeds and competition with the culture cease within a few hours after treatment. Due to the presence in the tank mixture of 2,4-D acid, the first visual symptoms of the effect of the drug on sensitive weeds become noticeable after 1-2 hours, which is faster than using a single herbicide on a sulfonylurea basis.

The death of sensitive weeds occurs usually in 3-7 days, complete death occurs in 2-3 weeks.

Less sensitive (field bindweed) or weeds that are in a later phase of development may be retained in crops, but their growth stops and they cannot compete with the culture in the consumption of nutrients and water.

Spectrum of action

Sensitive weeds: cyclist stork, ragweed ambrosia, radiant biforus, field thistle, speckled hemlock, field weed vetch, field sparrow, crow's foot, halinsog (species), geranium (species), mountaineer (species), field mustard, Tatar buckwheat, Glyphia (species), geranium (species), mountaineer (species), field mustard, Tartar buckwheat, Ghurano species Datura ordinary, pharmacy smoke, middle starlet, clover (species), spreading quinoa, flaxweed, burdock (species), field buttercup, alfalfa (species), field forget-me-not, shepherd's purse, clingy bedwort, weed sunflower, wilderness, rash sunflower, shepherd's purse, clingy weed wild radish, chamomile odorless, colza common, field violet, field yarutka.

Medium Sensitive Weeds: field bindweed, triad hibiscus, slumber, Molokan, Tatar, euphorbia, mint, field sow thistle, black nightshade, piculum (species), white sap, horsetail, chistets (species).

Period of protective action

Does not have a soil effect, affects only the weeds that were present at the time of treatment. Subject to the recommendations, as well as under the condition of optimal development of the culture, one treatment is enough to effectively suppress dicotyledonous weeds until the end of the growing season.

Recommendations for use

One package is designed for processing 10-11 ha.

The most effective use of the drug for actively vegetative weeds in the temperature range: from + 8 ° C to + 25 ° C.

Most annual weeds are most vulnerable to the action of the drug in the phase from 2 to 8 leaves or rosettes. The height of perennial root-emitters at the time of processing should not exceed 10-15 cm (for chucks, the phase of the outlet is the beginning of stitching). The development phase of the bedstraw should not exceed 4 whorls.

Field bindweed is most susceptible to the phase of budding, with lash lengths of 25-40 cm.

The optimal phase of the development of a culture for treatment with a herbicide is the tillering stage, however, it is permissible to use it in a wider timeframe: from 2–3 leaves before starting to enter the tube.

Factors Affecting Efficiency

The processing of crops should be under favorable weather conditions: in clear, warm weather, with sufficient moisture of the soil.

It is not recommended to carry out mechanical tillage for 2 weeks after the use of the drug, since this may disrupt the protective soil “screen” and the conducting system of weeds, which will reduce the effectiveness of their destruction.

Advice for use in adverse conditions

Apply the drug should be at a wind speed of not more than 5 m / s. During processing it is necessary to ensure that there is no demolition of the drug to neighboring sensitive cultures.

It is not recommended to carry out treatment on days when night frosts are predicted, due to the possibility of reducing the effectiveness of the drug. The precipitations that fell within 2-3 hours after spraying do not reduce the herbicidal effect of the drug.

Recommended tank mixes

Effectively suppresses dicotyledonous weeds when used alone, so it is not recommended to be combined with other dicotyledonous herbicides. For the simultaneous destruction of dicotyledonous and cereal weeds, it is recommended to use it in a tank mix with Graminicides FABRIS, GRASSER (in recommended consumption rates).

The possibility of resistance

The drug is recommended for use in anti-resistance programs. The composition of the drug includes three active ingredients with different mechanisms of action, eliminating the risk of resistant types of weeds.

Crop rotation restrictions

Due to the rapid decay period, tribenuron-methyl in the soil, as well as due to the reduced consumption rates of triasulfuron by 3 times, does not have an after-effect compared to independent use, and can be used without restrictions in all types of crop rotations.

Phytotoxicity

Subject to the recommendations on the timing and rates of application of the drug, no cases of phytotoxicity with respect to the treated crops were detected.

Compatibility

To expand the spectrum of action, BIATHLON PLUS can be used in tank mixtures with graminicides, as well as with various fungicides, insecticides, mineral fertilizers, microelements and growth regulators, growth stimulants and fertilizers used in the same time frame.

Before use it is recommended to check the components of the tank mixture for compatibility.

Storage conditions

When storing, avoid direct sunlight and observe the recommended temperature ranges. After the expiration of the warranty period of storage, the drug should be checked for compliance with the requirements of technical conditions. When establishing compliance, can be used for its intended purpose.

Chemical Treatment Efficiency

Preventive measures for the destruction of weeds, dressing their seeds can be carried out in early spring, autumn or throughout the summer. The effectiveness of the use of drugs depends on the following factors:

  • herbicide consumption rates
  • compliance with the manufacturer’s instructions,
  • weather conditions (temperature, air humidity, precipitation, wind),
  • sensitivity of weeds, beneficial crops to the components of chemicals,
  • processing time,
  • stages of vegetation development,
  • correct dilution of the liquid.

Classification of spraying plantings

The quality of destruction of weeds depends on the rate of consumption of herbicides. Based on this, experts classify spraying into the following groups:

  • ultra-small - up to 5 liters of liquid is spent per 1 ha,
  • low-volume with the help of aviation, fan sprayers - from 10 to 50 liters per hectare,
  • low-volume with the help of hose tools - 50-75 liters per hectare,
  • usual - 75-300 liters,
  • multi-volume - over 300 liters.

What does the rate of herbicide consumption depend on?

For processing grain, fruit, vegetable, berry crops, and also a decorative grass on lawns various chemicals are used. At the same time, the dosage of dilution of solutions, the amount of fluid applied to the soil, on the ground part of the seedlings depends on the following factors:

  • phases of development of weed vegetation (the higher the weeds, the more chemicals are needed),
  • types of weeds (the presence of malicious plantations that require more drugs),
  • competitiveness of crops, their varieties (uniformity, rarity of planting crops requires a different volume of solution),
  • weed abundance,
  • compatibility of goods with other types of pesticides.

How to determine the rate of consumption of herbicides?

To develop an approach to determining the amount of applied solution per 1 hectare of planted vegetation, in order to reduce the amount of applied chemicals, it is necessary to regularly monitor crops, conduct experiments, get expert advice and have high professionalism. Otherwise, the effectiveness of processing chemicals of weed will be minimal, and the quantitative indicators of the harvest will be reduced.

Why use chemical products?

Due to the emergence of weeds in the fields, kitchen gardens, the number of harvested fruits can be reduced by 80-90%, so it is important not only to buy appropriate products to combat the grass, but also to comply with the rules of herbicide consumption. Among the main reasons for using chemicals are:

  • reducing the complexity of the work,
  • reducing the time to fight grass
  • prevention of soil erosion,
  • increase in moisture, nutrients in the ground,
  • yield increase,
  • the preservation of the fertile layer of the earth, etc.

It is possible to make the developed preparations before the appearance of sprouts or after their active growth. You can make solutions by spraying, irrigation, pollination, dispersion of granules, mixing with mineral fertilizers or by applying on the tops of seedlings with the help of fabric wetting.

Herbicide Ballerina Description

Herbicide Ballerina has systemic activity, quickly, within 1 hour, penetrates through the leaves and spreads through all parts of weeds, including the roots, blocking the growth of cells in young tissues.

The growth of drug-treated weeds stops one day after treatment. Visible signs of action appear after 3–4 days (discoloration and twisting of the leaves, reduction of internodes).

Depending on the type of weed plants and weather conditions, the final death of weeds occurs 2 to 3 weeks after treatment.

The preparation provides protection of crops from the moment of processing until the appearance of a new “wave” of weeds.

The ballerina destroys more than 150 species of dicotyledonous weeds (including those resistant to 2,4-D and MCPA), among which is a tepid table, chamomile, field creeper, yellow thistle, field bindweed, blue cornflower, field mustard, shepherd's bag, field field , wild radish, white mary, common poppy, schichitsa species, mean starworm, mountaineer species, buckwheat vynunkovaya, polynnolistnaya ambrosia, Sophia descurinium, Tatar lettuce, dandelion, etc.

Spectrum of action

"Biathlon" attributed to artificial substances of systemic action, the main purpose of which was the destruction of one-year / two-year-old weeds and other grass-parasites on grain crops. The composition of the drug allows you to effectively deal with all dicotyledonous weeds, including harmful hard-flowering plants, the root system of which is quite extensive and deep. Weeds that are affected by the drug, depending on the speed of their reaction to the pesticide, can be divided into two groups:

  1. Sensitive: field mustard, field thistle, crow's foot, Tatar buckwheat, field buttercup, field violet, all kinds of alfalfa, common rape, rape, wild radish, field forget-me-not, bitter wormwood and others.
  2. Middle-sensitive: field horsetail, species of Chistets, field bindweed, horned triad, somnolence, Molokan, Tatar, euphorbiae, field mint, field sow thistle, black nightshade and others.

Active substance

In the composition of "Biathlon" there are such funds: "Elan" (emulsion concentrate), "Stalker" (water dispersible granules) and Dukat (water dispersible granules). The drug is able to cause weed death due to three groups of active substances:

  • 2,4-dichlorophenoxyacetic acid in the form of a complex 2-ethylhexyl ester is a white solid, slightly soluble substance in water, which acts well against chamomile, thistle and buckwheat. Cereals are resistant to 2,4-D.
  • Tribenuron-methyl - crystals of white color with a strong odor, suppressing broad-leaved weeds. In cereal plant tissues, the drug very quickly decomposes to non-toxic fibers.
  • Triasulfuron is a colorless and odorless solid that has the ability to kill dicotyledonous weeds in winter and spring crops.

Preparative form

Preparative form "Biathlon" is a mixture of emulsion concentrate (EC) and water-dispersible granules (EDC). It is packed in factory sealed binary packages with a volume of 4.5 liters, 0.09 and 0.03 kilograms.

Drug benefits

Based on the mechanism of action of the drug, the following advantages of this herbicide can be highlighted:

  1. Effective destruction of more than 100 species of parasitic plants.
  2. The probability of resistance of weeds to the drug is minimal, thanks to the three-component composition of the means of different spectrum of action.
  3. Excellent synergistic effect between the components, which enhances the productivity of the use of "Biathlon".
  4. Gentle effect on cereals, lack of phytotoxicity when used according to the instructions.
  5. The possibility of non-toxic combination with insecticides, which is necessary for the cultivation of a good crop.
  6. Safety by reducing the amount of triasulfuron in the composition compared to other herbicides.
  7. Long-term action, the emergence of the need for re-use - an extremely rare phenomenon.
  8. The “screen adaptation effect” is an extension of the drug’s action in the event of repeated weediness, which is facilitated by the combined reactions of tribenuron-methyl and triasulfuron.

Mechanism of action

"Biathlon" operates in two stages. First, 2,4-dichlorophenoxyacetic acid, as a hormonal substance, penetrates into the weed tissue and slows down the photosynthesis of parasitic plants by blocking the enzyme acetolactate synthase. As a result, the plant begins to malfunction, which is manifested in the deformation of the leaves and stems, loss of color, and then the death of the weed. At the second stage, tribenuron-methyl and triasulfuron negatively affect the production of valine and isoleucine, the most important plant amino acids. As a result, plant cells stop dividing, growing and developing, the body dies out.

Method, processing time and consumption rate

According to the instructions, "Biathlon" is applied by spraying with the help of special equipment of wheat and oats. The drug is recommended to treat the weed, which is in the phase of active vegetation at a temperature of 10-25 ° C. Maximum efficiency can be achieved if the parasitic plants are still “young”, when their growth does not reach 15 centimeters and there are 2-10 leaves on the stem. In order not to harm the grain crop, it is necessary to spray it during the tillering period before entering the tube in spring. The optimal rate of consumption of the working solution of the biathlon herbicide is an average of one pack per 10 hectares of planting area - about 200 liters per hectare.

Impact speed

Due to the presence of 2,4-dichlorophenoxyacetic acid in the preparation, the first effects of the herbicide “Biathlon” will be clearly visible after a few hours: weed leaves will start to wither. Herbicide quite quickly penetrates the plant, having the ability to accumulate in the tissues, deadening them. Young weeds die completely within 3-7 days, for more resistant ones it will take up to two weeks. It is possible that the drug will not kill all the parasitic plants, but in any case it will stop their development, and they will not harm the crops. After all, organisms that do not grow, do not have a special need for nutrients and moisture.

Compatibility with other pesticides

“Biathlon” refers to potent pesticides, which excludes the use of other dicotyledonous herbicides with it, since it can be dangerous and contribute to phytotoxicity. For the simultaneous destruction of dicotyledonous and cereal parasitic plants, it is allowed to use Biathlon in a tank mix with Fabrice. The drug is well compatible with mineral organic fertilizers, various insecticides (chemical preparations for combating harmful insects), growth stimulants and fungicides (biochemical means for the treatment of fungal diseases of plants).

Crop rotation restrictions

There are no serious restrictions on any of the crop rotations provided that the “Biathlon” is used strictly according to the instructions.
