    专利说明:

    This invention relates to chemical. agents for combating weed and undesirable vegetation, and specifically for a herbicidal composition containing active veterinary phosphorus compounds and auxiliary components from the group of liquid or solid carriers, sedimentary active substances, etc. Herbicidal formulations containing N-phosphonomethylglycine derivatives as active substances are known. These include, for example, a composition based on trimethyl-L-hydroxy-N-phosphonomethylglycinate and methyl N-oxy-N-dia. 2. However, the known compositions of this group are not effective enough. The aim of the invention is a new herbicidal composition based on a derivative of N-phosphonomethylglycinate, which has a higher herbicidal activity. This goal is achieved by using a derivative of N-phosphonmethylglycine-N-hydroxy-N-phosphonmethylglycine form. No-d-CHj-k-yngrg o he or its salts as active ingredients of the herbicidal composition. The content of the active substance in its herbicidal composition ranges from 1.5 to 95% by weight. Forms of application of the active substance are common: solutions, emulsions, pastes, powders, etc. They are prepared by well-known techniques. The method of obtaining N-hydroxy-K-phosphonomethylglycine is based on the interaction. VII N-oxyglycine with phosphoric acid and formaldehyde during catalysis with strong mineral acids. Table 1 presents the active substances of the herbicidal composition and examples illustrating its effectiveness. Apply r.Poslevskhodovoy application. The seeds of the experimental plants were sown in the prepared soil (under conditions of warming) and removed until a certain stage of development. After this, the plants were sprayed with preparative forms of the active substances. The evaluation of the germicidal effect was carried out 14 and 28 days after treatment on a scale
    - from O. to 24% damage
    - from 25 to 49% damage
    - 50 to 74% damage
    - from 75 to 99% damage - 100% damage.
