专利说明:

The invention relates to chemical means of controlling fungal diseases of plants, namely, a fungicidal agent based on 1,2,4-triazole derivatives. A fungicidal agent containing an active substance based on 1,2,4-triazole derivatives, for example 1- (2,4-dichlorophenoxy) -3,3-dimethyl-1- (1,2,4-triazol-1-yl ) butan-2-one, and additives from the number of hard and liquid carriers f1j. However, this tool is not effective enough. The closest to that proposed by the technical essence. And according to the achieved result is a pound agent containing an active substance based on 1,2,4-triazole derivatives, for example 1- (4-chlorophenyl) -4,4-dimethyl-2- ( 1,2,4-triazol-1-yl) -pentan-3-one, a solvent, such as dimethylformamide, and an emulsifier, alkylaryl polyglycol ether z}. A disadvantage of the known agent is low activity. The purpose of the invention is the enhancement of fungicidal activity. This goal is achieved by the fact that the fungicidal agent in the form of an emulsifiable concentrate contains derivatives of 1,2,4-triazole of the general formula as an active substance. R-jai-CO-C-CH YV, i where R is yropargil, cyclohexylmethyl, benzyl, 2-chlorobenzyl, 3-chlorobenzyl, 4-5sorbenzyl, 2,4-dichlorobenzyl, 2,6-dichlorobenzyl, 3,4-dichlorobenzyl , 4-fluorobenzyl, 4-chloro-3-trifluoromethylbenzyl, 4-nitrobenzyl 4-trifluoromethoxybenzyl; X is hydrogen, fluoro, chlorine; ; Y is fluorine, chlorine, or its hydrochloride salt, pr R - propargyl, benzyl, 3,4-dichlorobenzyl, cyclohexylmethyl, as the solvent g of dimethyl forms of the emulsifier - nonylphenol polyglycol ether, containing on average 18 alcohol groups per molecule, with the following ratio of components , weight: Derived 1,2,4-triazole 0, 25 Dimethylformamide 25.00 Nonylphenol polyglycol ether, containing on average 18 alcohol groups per molecule 0.06 The proposed remedy is prepared by simply mixing the ingredients at the indicated ratio. The triazole derivatives of the formula i, as well as their acid addition salts, are obtained by reacting a compound of the formula CH3 HjC-CO-C-CHzY where X and Y have the above values with an alkylating agent of the general formula R - Z, III where R has the above values and Z removes an emulsifying group, in the presence of a base and an organic diluent, or in an aqueous-organic two-phase system in the presence of a phase transfer catalyst, and the resulting product, if necessary, is reacted with an acid. Triazolylmethyl-trET.-butyl-: ketones of formula II are obtained by the interaction of haloketones of formula “3. Hal - CHf CO - C - CHzYi CHzX where X and Y have the above values and Hal - chlorine or bromine with 1,2,4 triazole in the presence of a diluent, for example acetone, and a binding acid, for example potassium carbonate, at 20 -. Halogen n-ketones of formula 1U are obtained by mixing a compound of the formula of the formula CH3-Co-C-SNU where X and Y have the above values in an inert organic solvent at room temperature with chlorine or bromine; or it is reacted by conventional means of chlorination, for example, sulfuryl chloride, at 20-60 ° C. Means of alkylation of the formula. III are known compounds of organic chemistry. Inert organic solvents are used as diluents, for example, aromatic hydrocarbons (benzene, toluene or xylene) halogenated hydrocarbons (methylene chloride, carbon tetrachloride chloroform or chlorobenzene), ester (acetic acid), formamides (dimethylformamide), and also dimethyl sulfonic acid. in the presence of organic and inorganic bases, such as alkali metal hydroxides or alkali metal carbonates, such as potassium and sodium hydroxides j Reaction temperature from O to, preferably from 20. To the reaction, 1-1.2 mol of an alkylating agent is used per 1 mole of triazolylmethyl-tRET.-bu, of a til-ketone of the formula II.The separation of the target products of the formula t is carried out by known methods. The action can also be carried out in a two-phase system, for example, in sodium liquor or a solution of caustic potash and toluene, or in methylene chloride, with the addition of 0.11 mole of a phase transfer catalyst, for example, ammonium or phosphonium-benzyldodecyldimethyl chloride and ben zyl chloride ammo uh. The compounds obtained are given in table. one .
