Abstract

FIELD: organic chemistry, fungicides. SUBSTANCE: invention describes method for inhibition of fungus growth associated with plant. Method involves applying on plant locus fungicidally effective dose of (S)-enantiomer of 1-[2-(2,4-dichlorophenyl)-2-(propenyloxy)ethyl]-1H-imidazole comprising 20%, not above, of (R)-enantiomer with respect to the total amount of 1-[2-(2,4-dichlorophenyl)-2-(propenyloxy)-1H-imidazole (fungicide imazalyl); fungicide composition containing (S)-enantiomer of 1-[2-(2,4-dichlorophenyl)-2-(propenyloxy)ethyl] -1H-imidazole, not above, with respect to the total amount of (R)-enantiomer of 1-[2-(2,4-dichlorophenyl)-2-(propenyloxy)ethyl] -1H-imidazole, and agrotechnically acceptable carrier; fungicide composition comprising 1-[2-(2,4-dichlorophenyl)-2-(propenyloxy)ethyl] -1H-imidazole enriched with at least 40 weight % (S)-enantiomer. Indicated compositions are effective against such fungi as Aspergillus nidulans (phytophtorosis) and Erysiphe graminis (true powdery mildew). EFFECT: enhanced antifungal properties of compounds. 14 cl, 3 tbl, 6 ex
