    (54). GERBICID MEANS
    one
    This invention relates to chemical means of controlling weeds and undesirable vegetation.
    Known herbicidal agents based on benzoxazine derivatives. These include / for example, a herbicidal agent containing the active substance - a benzoxazine derivative, and additives - xylene, an addition product, not 8-10 moles of ethylene oxide to 1 mole of oleic acid N-monoethanolamide, a calcium salt of dodecylbeisole sulfonic acid, and an addition product of 40 moles ethylene oxide to 1 mole of caste., solid oil.
    A disadvantage of the known herbicidal agent is that its effect on certain types of weed plants is not always satisfactory. jo
    The aim of the invention is to enhance the herbicidal action of the agent.
    This goal is achieved by the fact that the herbicidal agent contains an active substance. A derivative is a benz-25 derivative of the general formula
    where R is hydrogen, chlorine, fluorine;
    C - thiophen-2-yl, 3-methylthiophene; - X -: -.- 2-ll or radical
    in which
    X is trifluoromethyl, difluoromethyl, fluorodichloromethyl or 1,2-dichlorovinyloxy, provided that X does not mean trifluoromethyl, if P is hydrogen, and the additive is xylene, the product of addition of 8-10 mBl of ethylene oxide to 1 mole of N-mono-ethanolamide of oleic acid, the calcium salt of dodecylbenzene sulfonic acid and the product of addition of 40 moles of ethylene oxide to 1 mole of castor oil, with the following content of components, weight, -:.

    EXAMPLE In a greenhouse, the procedure is 0 0, as follows.
    Seeds of experimental plants finely for-. sow by varieties in plastic-flower pots with a volume of 300 cm, filled with clay with 1M sand with 1.5% gum-15 as a substrate. After the plants reach a height of 3-10 cm, they are treated with the suggested herbicidal agent diluted with water to the required concentration., 20. Experimental pots are then placed in a greenhouse in different areas of temperature, namely: plants that like heat at a temperature of 20-30 ° C, and 3-trifluoromethylphenyl

    3-difluorochloromethylphenyl
    Chlorine
    Plants of temperate climate - at a temperature of 10-20 seconds. The period of experience lasts 3-4 weeks. During this time, the plants are looked after and their response to herbicidal preparations is evaluated. The assessment is carried out on a scale from 0 to 100. Herewith, O means that there was no damage or normal shoot, and 100 means that there was no shoot of plants, complete destruction of at least the above-ground parts of the shoots.
    In table 2-4 shows the results of experiments.
    For comparison, a well-known herbicidal composition based on 2- (3-trifluoromethylphenyl) -4H-3,1-benoxazin-4-one (herrcide A) is used.
    The experimental data presented in Tables 2–4 demonstrate the high efficacy of the proposed herbicidal agent in relation to weeds and its good selectivity of action.
