This invention relates to chemical plant protection products, specifically to a fungicidal agent (and its variants) based on a triazole derivative.
Known fungicidal agent based on esters of thiophosphoric acid l.
The closest to the one proposed is a fungicidal agent in the form of an emulsifiable concentrate or powder based on triazole derivatives, an alkylaryl sulfonate and ether surfactant or alkyl sulfonate surfactant and an organic solvent dimethylformamide and xylene or powdered carrier kaolin 2.
However, these fungicidal agents have insufficient activity at low concentrations.
The purpose of the invention is to increase the fungicidal activity of the agent.
To achieve this goal, the invention contemplates the use of a fungicidal agent in its variants.

0 dimethyl sulfate. The reaction mixture was heated under reflux for one hour. In this case, two phases are formed. After cooling (the reaction mixture is mixed with ice water, after which the toluene phase is separated. The product which is drawn off is sucked off from the aqueous phase, mixed with dimethylformamide in a hot state, cooled and sucked off.
d Additionally washed with cold ethanol. Obtain 105 g (68% of theory) of the specified target product. From the toluene phase one can also still separate the desired product. T. pl.

Germination and germination take place in favorable conditions in the greenhouse. After 7 days after sowing, when the barley plants released the first leaf, they are sprinkled with fresh spores of Erysiphe graminis var, hordei and cultivated further at 21-22 C, relative humidity of 80-90% and illumination for 16 hours. For 6 days Leaves form typical powdery mildew pustules. The degree of damage is expressed as a percentage of the lesion of untreated control plants, at O% there is no lesion, and at 100% the lesion rate is the same as that of untreated control plants.
