    专利说明:

    This invention relates to chemical methods for controlling weeds and unwanted vegetation.
    Known methods of controlling undesirable vegetation are based on the use of sulfonylurea derivatives as active substances.
    However, the known methods are not sufficiently effective for certain types of weeds.
    The purpose of the invention is to increase the germicidal effect of the method of weed control based on the use of sulfonylurea derivatives.
    This goal is achieved by using new sulfonylurea derivatives as active substances.
    Example 1. Getting (| 5- ethylsulfonylethyl) -N-methyl sulphamoyl-N - (h, b-dimethoxypyrimidin-2-yl) urea (compound k b) o
    To a solution of g of Z-aMMHo-b-flHMe-toxipyrimidine in 50 ml of methylene chloride a solution of 7J g of chlorosulfonyl isocyanate in 50 ml of methi- is added dropwise. Lenchloride.
    After that, the reaction temperature is. the mixture is brought to -30 ° C, a solution of 7 | 6 g of ethyl - ((5-methylaminoethyl) sulfone and 5.1 triethylamine in ml of methylene chloride) is added dropwise, heated to room temperature and stirred

    another 16 hours. The resulting reaction mass is washed with 2N hydrochloric acid and water (10U ml each), dried over magnesium sulfate, the solvent is distilled off, the residue is triturated with ether and 10, i g of the final product is obtained, 15U -.
    Under the conditions of Example 1, other compounds are obtained, the list of which is presented in Tal.1.
    PRI me R 2, Dovskhodov treatment of plants.
    Seeds of experimental plants are sown in special pots with sandy loam and covered with soil. After that, the soil is treated with preparative forms of the active substances and the plants are grown under greenhouse conditions for 3 - weeks. The evaluation of the Urbicidal action is carried out visually on a scale from 0 to 1 point:
    0- no effect;
    1- up to 2U5 &damage;
    2-20 - 0% damage;
    3- 0 - L0% damage; C - 60 - 80% damage; i - 80 - TUO &amp; Damage Control serve as raw
    plants.
    For comparison, use is known
    The results of the experiments are presented in table 2.
    PRI me R 3 - Post-harvest processing of plants.
    Experimental plants grown under greenhouse conditions up to stage 3 of the sheet are treated with preparative forms of active substances and after 3 weeks after treatment, the degree of herbicidal effect is determined as in Example 2.
    The results of the experiments are presented
    at .
    Invention Formula
    A method of controlling undesirable vegetation by treating it or the soil on which it grows is a sulfonylurea derivative, characterized in that, in order to increase the herbicidal effect, a compound of the general formula is used as a sulfonylurea derivative.
