Advantages

An effective means for destroying annual and perennial grass weeds;

Destruction of the aboveground part and root system of weeds;

High speed of action;

Long-lasting action against perennial weeds - throughout the entire growing season;

Can be used in any phase of cultural development;

Resistant to precipitation - within an hour after treatment it does not have a negative effect on the effectiveness of the herbicide

Mechanism of action
Klegal is a selective systemic herbicide. Both active substances inhibit the biosynthesis of fatty acids as a result of inhibition of acetyl-CoA carboxylase. Haloxyfop-R-methyl enters the plant through leaves and roots and is hydrolyzed to haloxyfop-R, which moves into meristem tissues and inhibits their growth. Cletodim is quickly adsorbed and moves from treated leaves to the root system and growth points of weeds.

Rate and symptoms of exposure

Symptoms of the herbicide effect appear within 1-3 days after treatment, the death of the weeds occurs within 1-2 weeks, depending on the type of weed, the phase of its development and weather conditions.

Spectrum of action of the drug

Annual and perennial cereals (including creeping wheatgrass), weeds.

Period of protective action

The drug penetrates into plants through above-ground organs and moves to the root system, therefore the effect of the drug is noted on weeds found in the crop during the period of treatment with the drug. The herbicide does not penetrate the soil and has no effect on weeds that appear after spraying. The effectiveness of the drug is maintained, as a rule, throughout the entire growing season.

Recommendations for use

Before preparing the working solution, the drug should be thoroughly mixed in the original packaging. Measure out the amount of the drug required for one filling of the sprayer. Next, the working solution is prepared as follows: the sprayer tank is filled approximately half with water, the required amount of herbicide is poured into it, and water is added until

full volume with constant stirring of the solution with hydraulic mixers. At the same time, wash off the container in which the herbicide was stored several times with water.

Factors influencing efficiency

Low (less than +10°C) or high (more than +25°C) air temperatures, drought, frost and other stress factors during the period of application of the drug can significantly slow down the effect of the drug on weeds (signs of the herbicide action appear 3-5 days later) and also reduce its effectiveness.

To obtain the maximum effect in the fight against perennial grasses, it is necessary to exclude the cultivation of rows for two weeks after treatment, until the process of dying off of the rhizomes becomes irreversible.

Recommendations for use in adverse conditions

It is not recommended to use the drug at wind speeds of more than 5 m/s. During processing, it is necessary to ensure that there is no drift of the drug onto neighboring sensitive crops.

Spraying should not be carried out during periods when the leaves of weeds and cultivated plants are moistened.

In case of high infestation of crops and in the presence of overgrown weeds, treatment should be carried out with the maximum dose of the drug recommended for the crop.

Phytotoxicity

It is not phytotoxic for most dicotyledonous crops, but destroys annual cereal weeds and creeping wheatgrass.

Recommended Tank Mixes

Compatible with herbicides based on desmedipham, phenmedipham and etofumezate, herbicides based on clopyralid, arbitrary sulfonylureas and a number of other active ingredients. Also compatible with many insecticides and fungicides. Not compatible with pesticides that have an alkaline reaction (pH more than 8.5).

If Klegal is used in a tank mixture with other pesticides, the drugs must be mixed in the water of the sprayer tank in the following order: Each subsequent component is added after complete dissolution (dispersion) of the previous one. Before use, it is necessary to check the physical compatibility of the components of the tank mixture.

Possibility of resistance

No cases of drug resistance have been identified. To avoid the emergence of resistance of cereal weeds to the drug, it is advisable to alternate the use of the drug with herbicides of other chemical groups.

Storage conditions

When storing, avoid direct sunlight and maintain recommended temperature ranges. Upon expiration of the guaranteed storage period, the drug must be checked for compliance with technical specifications. Once compliance is established, it can be used for its intended purpose.

Applied by crops:

Sugar beets, spring and winter rape, soybeans, sunflower (for seeds and oil) Peas, buckwheat, lupine, alfalfa, lentils, safflower, mustard, cotton, fiber flax, oil flax, potatoes.
