    FIELD: chemistry. remedies with weedy and undesirable vegetation, namely, a herbicidal composition containing the active ingredient from 2,1,3-benzothia-diazinone-4 derivatives and auxiliary components from the group of liquid or solid carriers, surfactants, etc. . Herbicidal compositions are known. Based on 2,1,3-benzothiadiazcnone-4 derivatives. These include, for example, a composition based on 1-acyl 3-isopropyl-2, 1, 3-be-nzothiadiazin-4-one 2.2 dioxide and composition., the active ingredient of which is 2,2-dioxide-1-halomethyl-3-isopropyl-2,1, 3-benzothiadiazin-4-one. One known herbicidal composition is not sufficiently effective for individual weed species. The aim of the invention is a new herbicidal composition based on a derivative of 2.1.1 benzothiadiazinone-4, which has an increased herbicidal activity and selectivity of action. This goal is achieved by the use of 2.2 dioxid-2, 1 hZ-benzothiadiazin-4-one general formula of the formula I xy, where R is C-alkyl or cyclopropyl as the active substance of the herbicidal composition. . R, -CN, SCC1, F, H, or O. (JHz OtiH ,, X is methyl halogen, methoxy m O is 2. The active substance content in the herbicidal composition ranges from 0.1 to 95% by weight. Forms of active ingredients, conventional: solutions, emulsions, pastes, powders, etc. They are prepared by known techniques. The method of obtaining compounds of general formula D is based on the interaction of 3 substituted derivatives of 2,2-dioxide-2, 1, 3-benzothiadiazin-4 - it with halogen-containing compounds,
    in which Tlj is as defined above, in the presence of an acceptor, g aloids of hydrogen.

The seeds of the experimental plants were sown in the prepared soil and immediately after that the soil was treated with preparative forms of the active substances (pre-emergence application). Test plants grown under greenhouse conditions up to a height of 3-10 cm were treated with preparative forms 65
    Below are the compounds of general formula I, studied as active substances of the herbicidal composition. active ingredients (post-harvest application). In both cases, after treatment, plants continued to grow under greenhouse conditions for 2–4 weeks and the herbicidal effect was evaluated on a scale from 0 to 100: O — no effect; 100 - full of death of plants. Example 2. Experience in field conditions
    Experiments were carried out on small cases under post-emergence conditions. The evaluation was carried out after a few weeks on a scale described above (example 1).
    For comparison, known compounds with herbicidal activity were used:
    A - bentazone (2,2-dioxide-3-isopropyl-2, 1,3-benzothiadiazin-4-one); Pre-emergence treatment in greenhouse conditions.
    B - 2,2-DIOXID-1,8-dimethyl-3-isopropyl-2, 1,3-benzothiadiazin-4-one;
    B - 2,2-DIOXID-3-IZOPROPIL-8-chloro-2, 1, 3-benzothiadiazin-4-one;
