    专利说明:

    The invention relates to chemical plant protection agents, specifically, to a fungicidal agent in the form of an emulsifiable concentrate based on 1,2,4-triazol-1-butyl-2-derivatives.
    Known fungicidal agent based on 1,2,4-triazole derivatives
    pz.
    The closest to the present invention is a fungicidal agent based on a derivative of 1,2,4-triazole-1-butyl-2-dimethylformamide and alkyl aryl polyglycolic ether G23.
    . However, these fungicidal agents have insufficient activity at low concentrations.
    The purpose of the invention is to increase the fungicidal activity of the agent.
    This goal is achieved in that the fungicidal agent in the form of an emulsifiable concentrate containing the active ingredient contains 1,2, triazole-1-ylbutanol-2 as a derivative, a compound of the general formula

    , Dimethylformamide Nonylphenol polyglycol ether, containing on average 18 alcohol
    0.06 groups per molecule. The proposed agent is prepared by simple mixing of the components. Compounds (I) are obtained by reducing the corresponding ketones, which are carried out by reacting with complex hydrides, if necessary in the presence of a diluent, or by reacting with aluminum isopropoxide in the presence of a diluent, or by reacting with hydrogen in the presence of a catalyst and, if necessary. diluent
    When using complex hydrides as a diluent, polar organic solvents, preferably methanol, ethanol, butanol, isopropanol, diethyl ether, tetrahydroFuran, are suitable for reaction. The reaction is carried out at 0-30, preferably at. Apply per mole of ketone to approximately 1 mole of a complex hydride, such as sodium borane or lithium alanate. In order to obtain the reduced compounds of the formula (I), the residue is taken up in a dilute roll acid, then alkalinized and extracted with an organic solvent. Recycle in the usual way.
    In the case of using aluminum isopropyl as a diluent for the reaction, preferably spiters, such as isopropanol or inert hydrocarbons, such as benzene, are suitable. The reaction temperature is 20-120 s (preferably 50 LU s). Approximately 1-2 mol of aluminum isopropylate are used per mole of ketone for the reaction. To isolate the recovered compounds of formula (I), excess solvent is removed by vacuum distillation and the resulting aluminum compound is decomposed with dilute sulfuric acid or sodium hydroxide. Recycle in the usual way.
    In the case of using hydrogen as a diluent, polar organic solvents, preferably methanol and ethanol, acetonitrile, are suitable for the reaction. The reaction is carried out in the presence of a catalyst; preferably, noble metal catalysts, noble metal oxides or noble metal hydroxides, or so-called Rene catalysts, in particular platinum, platinum oxide and nickel, are preferably used. Reaction temperature 20-50С. The reaction can be carried out at normal or elevated pressure, for example 12 MPa. For the reaction, about 1 mole of hydrogen and 0.1 mole of catalyst are used per mole of ketone. To isolate the reduced compounds (I) thereof. filtered from the catalyst and freed from the solvent in vacuo. Recycle in the usual way.

    The compounds obtained by the proposed method are listed in Table 1.

A barley plant (Amsel variety) with 1 leaf is sprayed with an aqueous fungicide preparation consisting of parts by weight: active ingredient 0.25, dimethylformamide 25 and nonylphenol polyglycol ether 0.06, containing an average of 18 alcohol groups on the molecule. After suspending, the plants are barren with spores of Egusiphe graminls var.hordei .. After. 6 days of plant storage at 21-22 s and 80-90% air humidity determine the defeat of plants by powdery mildew pustules. The extent of the damage is determined as a percentage of the damage to the untreated control plants. At the same time, 0% means no damage, and 100% means the same degree of damage as that of untreated control plants. The active substances and the results of the experiment are summarized in table. 2.

Young barley plants are sprayed to form droplets with an aqueous fungicide preparation consisting of parts by weight: active substance O, 25, dimethylformamide 25 and nonIlphenol polyglycol ether 0.06, containing on average 18 alcohol groups per molecule. After drying, the plants are sprayed with spores of Erysiphe graminis f.sp, hordei. Plants are stored in a greenhouse at 20 s and a relative humidity of 80% for 7. days Then the degree of damage (in%) of the untreated control plants is determined. In this case, 0% no damage, and -100% means Example 3. Young plants are sprayed before dropping
    an aqueous fungicide preparation consisting of parts by weight active substance 0,25 ,. dimethylformamide 25 and nonylphenol polyglycol ether 0.06, containing an average of 18 alcohol groups per molecule. After drying, the plants are sprayed with spores of the fungus Sphaerotheca fuliginea. The plants are then stored in a greenhouse at
    23-24 ° C and a relative air humidity of 75% for 10 days, after which the extent of damage (in%) from untreated control plants is determined. At the same time, 0% - no
