    专利说明:

    This invention relates to chemical methods for controlling weeds and unwanted vegetation.
    The aim of the invention is to increase the selectivity of the action and shorten the period of phytotoxic action of the herbicide in the soil using the weed control method based on the use of sulfonylurea derivatives.
    Example 1. Preparation of M-methyl-M- (4-methoxy-6-methyl-1,3,5-triazin-2-yl) -M (2-methoxycarbonylphenylsulfonyl) urea (compound A).
    To a solution of 22.4 g (93 mmol) of 2-methoxycarbonylbenzenesulfonyl isocyanate in 100 ml of dichloromethane was added 10.7 g (69.9 mmol) of 2-methoxy-4-methyl-6-methylamino-1,3,5-triazine and a catalytic amount of 1,4-diaza (2,2,2) bicyclooctane. The reaction mixture is stirred in a stream of nitrogen at ambient temperature for
    10-12 hours, the solvent is distilled off, the residue is triturated with diethyl ether, washed with chlorbutane and a solid with a melting point of 126-131 ° C is obtained, yield 27.8 g
    Example 2. Determination of herbicidal action.
    Seeds of experimental plants are sown in prepared soil and immediately after that the soil is treated with a solution of the active substance in a non-phytotoxic solvent (pre-emergence treatment)
    In post-harvest treatment, test plants are grown under conditions of heat up to a height of 1-15 cm and then treated with a solution of the active substance.
    The assessment of the herbicidal effect is carried out after weeks of treatment and expressed as a percentage.
    For comparison, the known herbicide M- (4-methoxy-6-methyl-1,3 5-tria (/)

    Zin-2-yl) -Y1- (2-methoxycarbonylphenylsulfonyl) urea (compound B).
    The results of the experiments are presented in table. 1 and 2.
    Example 3. Determination of the rate of decomposition of a herbicide in soil (half-life).
    The prepared soil with a high pH value is treated with a herbicide, mixed thoroughly and incubated at 30 ° C for a certain time. After that, sensitive plant species are sown in the soil and followed by their development.
    In the second embodiment, the same soil is treated with the same herbicide in various doses and immediately sown into it the same sensitive plants.
    The growth of the test plants and the degree of exposure of the herbicide to them are evaluated after 21 days. The content of the herbicide remaining in the incubated soil is then determined and the extent of the effect of the herbicide on the plants in the non-incubated soil is evaluated.
    Based on the initial concentration of the herbicide in the soil, its residual amount and the number of days of incubation, the half-life of the herbicide is determined.
    In the experiment with compound A, 35 g / ha of herbicide are embedded in the soil, and the incubation of the soil is carried out for 10 days.
    In the experiment with compound B, L-9 g / ha of herbicide is embedded in the soil and the soil is incubated for 95 days.
    The results of the experiments are presented in table. 3 and A.
    From these results, the concentration of the remaining herbicide in the soil and its half-life are determined.
    In the first case (compound A), the residual concentration is 7 g / ha, and the half-life is about 4 days.
    In the second case (compound B), the residual concentration is 4 g / ha, and the half-life is about 40 days.
    Thus, the proposed compound has not only an increased selectivity of action with respect to
