    This invention relates to chemical agents for controlling weeds and undesirable vegetation. The purpose of the invention is to selectively kill weeds in crops of cultivated plants using a herbicidal agent containing a common sulfonyl urea derivative (Formula 2R -CH S02NHC (0) NR2-A, where R is chlorine, C, -Cd-alkoxycarbonyl, 2- chloroethoxycarbonyl, allyloxycarbonyl, dimethylaminocarbonyl, pyrrolidinecarbonyl; R — propargyl or the group R — CHj — CRj CR R—; Rj — H Rg — hydrogen, methyl, chlorine; R — hydrogen, methyl, chlorine, phenyl; A — 4 -RJ-6R -niripidin-2-yl or 1,3,5-triazinyl-2-yl; - Rz-hydrogen, methyl, methyloxy, ethyloxy, chlorine, dimethylamino; R-hydrogen, methyl , methyl-- hydroxy; carriers - kaolin and silicic acid and surfactants - sodium salt of L | -methyl-H, -oleyl-urine and calcium salt of ligninsulfonic acid at a mass ratio of 25: 60: 10: 1: 4, respectively The herbicidal agent according to the invention makes it possible to effectively deal with weeds in crops of wheat and soybean. 3 Table.

    专利说明:

    This invention relates to chemical means for controlling weeds and unleavened vegetation.
    The purpose of the invention is to improve the action of herbicidal agents based on urea sulfonyl derivatives.
    The proposed herbicide remedy wins, wt.%:
    Active substance 25 Kaolin60
    Silicic acid 10 Sodium salt -Y-methyl-N-oleyl taurine 1
    Calcium salt
    ligninsulfonic acid 4
    Example 1. The proposed herbicidal agent is suspended in water and treated by experienced asthenia with pre-emergence and post-emergence methods in a greenhouse with an estimated 500 l / ha of aqueous suspension (3 kg / ha of active substance),
    Evaluation of herbicidal activity was carried out 3 weeks after treatment on a scale: O — no effect; 1 - average damage; 2 - severe damage; 3 - full growth inhibition; 4 is full of plant death.
    The results of the experiment are presented in table. 1.
    Example 2. Seeds of monocotyledonous and dicotyledonous weeds, as well as cultivated plants (wheat and co), are planted in pots with humus-containing sandy soil and covered with earth. The proposed herbicidal composition is applied as a suspension with 500 liters of water per hectare at a consumption rate of 0.1 kg of the active substance per hectare before the emergence of weeds.
    After processing, the pots are placed in a greenhouse and test plants are grown in greenhouse conditions. 4 weeks after treatment, plant damage was assessed according to the scale described in Example 1.
    The results of the experiment are presented in table. 2
    As can be seen from the table. 2, all weeds are destroyed without damage to cultivated plants, while a known substance also damages cultivated plants.
    Example 3. Seeds of dicotyledonous weeds, wheat and soybeans are sown in pots and grown in a greenhouse. Through
    five
    0
    five
    3 weeks after sowing, the test plants are treated in a 1-4 leaf stage. In this purpose, the herbicidal composition is applied as a suspension with 500 l of water per 1 ha. 4 weeks after treatment, plant damage is assessed according to the scale described in Example 1.
    The results of the experiments are presented in table. 3. For comparison, a herbicidal substance containing a known herbicide, (4-methoxy-6-methylpyrimidin-2-yl) -3- (3-methoxycarbonylaminophenylsulfonyl) urea, is used as an active substance.
