FIELD: chemistry.SUBSTANCE: invention relates to agriculture. The agrochemical composition contains a long-chain N,N-dialkyl alkylamide of formula , where: (a) each of R1 and R2 is independently a linear alkyl radical having 4 to 20 carbon atoms, and R is an alkyl group having 6 to 30 carbon atoms, the total number of carbon atoms in R, R1 and R2 is greater than 40； and at least one azole active ingredient of formula and in which R1 is phenyl, 4-chlorophenyl, 4-chlorophenylethyl, 4-chlorophenyl, 2,4-dichlorophenyl, or 4-chlorophenyloxy； R2 is n-butyl, tert-butyl, phenyl, 2-fluorophenyl or a group of general formula : R3 is hydroxyl, oxygen or cyano. The composition additionally contains at least one member selected from a group consisting of a surfactant, an organic solvent and a low-temperature stabiliser. An aqueous aerosol composition contains said composition and water. Lon-chain N,N-dialkyl alkylamide is used to inhibit and/or prevent growth of crystals of pesticide-active azole derivatives. The long-chain N,N-dialkyl alkylamide is added to a pesticide composition in an amount which is sufficient to reduce crystallisation of the azole derivative. For mycosis control, said composition is applied in the focus.EFFECT: invention increases efficiency of inhibiting growth of crystals of pesticide-active azole derivatives.20 cl, 15 tbl, 15 exИзобретение относится к сельскому хозяйству. Агрохимическая композиция содержит N,N-диалкил алкиламид с длинной цепочкой формулы (I)где: каждый из R1 и R2 независимо представляет собой радикал линейного алкила, имеющего от 4 до 20 атомов углерода, и R представляет алкильную группу, имеющую от 6 до 30 атомов углерода, общее количество атомов углерода в R, R1 и R2 больше 40； и по крайней мере один азольный активный ингредиентформулы (II), в которой R1 представляет фенил, 4-хлорфенил, 4-хлорфенилэтил, 4-фторфенил, 2,4-дихлорфенил или 4-хлорфенилокси； R2 представляет собой н-бутил, трет-бутил, фенил, 2-фторфенил или группу общей фо
