    专利说明:

    The invention relates to chemical pest control agents, namely, to a fungicidal agent based on an alanine derivative (its variants). A fungicidal agent is known, containing as active substance a compound of the general formula „„ jf SOI where X is halogen, V is hydrogen, halogen l. A fungicidal agent in the form of an emulsifiable concentrate is known, containing as an active substance methyl K-F (2-furancarbnyl) -M- (2, 6-dimethylphenyl) -alanine methyl FIR and auxiliary cokshon-surfactant and stabilizer I. However, the activity of this means is insufficient. The purpose of the invention is the enhancement of fungicidal activity. This goal is achieved by a fungal agent in its variant solutions. 1. A fungicidal agent in the form of an emulsifiable concentrate, containing, as a derivative, alanine methyl EFIR M - (2-furancarbonyl) -I- (2-methyl 4-bromo-naphthyl) -alany of the formula - c H $.

The mixture is then mixed into 700 ml of ice water, the product is extracted 3 times with 100 ml of ether. The purified ether extracts are washed once with 100 ml of IN sodium hydroxide solution and once with water, dried and concentrated. 17 g (62% of theory) of N - (2-furancarbonyl) -N- (2-methyl-4-bromo-naphthyl) -alanine methyl ester are obtained in the form of a colorless gum. .
