FIELD: chemistry.

SUBSTANCE: invention relates to agriculture. The compound is selected from a group including formula 1, formula 2, formula 3, formula 4, formula 5 and formula 6. Formula 1 is , where R₁ = isobutyl, sec-butyl or tert-butyl-CH₂; R₂=H; n=0-25. Formula 2 is , where R₁ = sec-butyl or tert-butyl-CH₂; R₂=H. Formula 3 is , where R₁ = isobutyl, sec-butyl or tert-butyl-CH₂; R₂=H. Formula 4 is , where R₁ = isobutyl; R₂=H; R₃ = n-alkyl containing 2-25 carbon atoms, except n-heptyl and n-undecyl, branched alkyl containing 4-25 carbon atoms, substituted or unsubstituted cycloalkyl containing 3-25 carbon atoms, or substituted or unsubstituted arylalkyl containing 12-26 carbon atoms; or R₁ = sec-butyl or tert-butyl-CH₂; R₂=H; R₃ = n-alkyl containing 1-25 carbon atoms, branched alkyl containing 3-25 carbon atoms, substituted or unsubstituted cycloalkyl containing 7-25 carbon atoms, or substituted or unsubstituted arylalkyl containing 7-25 carbon atoms; or R₁ = isobutyl; R₂ = methyl; R₃ = n-alkyl, containing 2, 3, 6 and 12-25 carbon atoms, branched alkyl containing 3-25 carbon atoms, substituted or unsubstituted cycloalkyl containing 3-25 carbon atoms, or substituted or unsubstituted arylalkyl containing 7-25 carbon atoms. Formula 5 is , where R₄=H, alkyl, haloalkyl, alkoxy, alkylthio, haloalkoxy or haloalkythio, each containing 1-4 carbon atoms, or halogen, hydroxyl group, nitro group, carboxylic acid group or cyano group; an either R₁ = sec-butyl or tert-butyl-CH₂; and R₂=H; or R₁ = isobutyl; and R₂ = methyl; and formula 6 is , where R₄ = H, alkyl, haloalkyl, alkoxy, alkythio, haloalkoxy, haloalkylthio, each containing 1-4 carbon atoms, or halogen, hydroxyl group, nitro group; carboxylic acid group or cyano group; and either R₁ = isobutyl, sec-butyl or tert-butyl-CH₂; R₂=H; or R₁ = isobutyl; and R₂ = methyl. Said compounds are used to attract zoospores of plant pathogenic oomycetes of fungi or control plant diseases.

EFFECT: invention increases treatment efficiency.
