    The invention relates to chemical means of controlling weeds and undesirable vegetation, and specifically to herbicidal compositions based on nitrogen-containing heterocyclic compounds. Herbicidal compositions containing, among other things, surfactants and fillers, active compounds from the number of pyrazine derivatives are found. These include, for example, a herbicidal composition based on 2, 3,6-tri-chloro-5- (trioxid metric) -parazin l. However, the known compositions of this group are not sufficiently effective for some types of weeds. The aim of the invention is to increase the herbicidal activity of a composition based on pyrazine derivatives. This goal is achieved by a herbicidal composition containing as active substances a pyrazine derivative of the general formula A I & where A is hydrogen, C (-C5-alkyl, phenyl, benzyl, phenyl, substituted by methyl, methoxy, halogen or nitro, 3,5-dimethoxyphenyl, dichlorophenyl, C-C4-alkoxy, phenox, phenoxy, substituted by methyl and / or chlorine, dichlorophenoxy, C.-C, - ° alkylthio, phenylthio, benZSh1TIO, ethoxycarbonylmethylthio, ethylamino, propylamino, dimethylene but tetrametilenimino, phenylamino, benzylamino, B is hydrogen, chloro, bromo, iodo, C -C- alkyl, phenyl, substituted xjiopotf, bromine, hydroxyl, methyl or methoxy, methoxy or ethoxy, allyloxy, propynyloxy, 1-ethoxycarbonyl ethyloxy; phenoxy; -Sz-alkylthio, C--S5 apkilamino, C, -C dialkylamino, karboksimetiptio, .etoksikarbonilmetil, phenylthio, chlorophenylthio, metililtio, benzylthio, 4-chlorobenzyl, ethyleneimine, tetra1etilenimino, pentamethylenimine, morpholino ,. phenylamino, chlorophenylamino, methokphenylamino, chlorphenylamino, methoxyphenylamino, butylphenylamino, siphenylamino. butylLenylamino.

The proposed herbicidal composition is effective both in tillage and in the treatment of vegetative plants. It is especially effective in controlling weeds in rice crops. To prepare the herbicide composition, all the ingredients included in it are mixed and ground into powder. Below are the active substances of the general formula I and examples illustrating the effectiveness of the herbicidal composition.

    Polyethylene pots fill the soil for sowing rice and weed seeds are embedded in it to a depth of 2 cm. Rice sprouts in the 2–3 leaf stage are transplanted here and the soil is filled with water up to 3 cm above the surface.
    The proposed wettable powder is diluted with water and applied to the surface of the water by dropping. Thereafter, the plants are grown in a glass chamber, and 3 weeks after the treatment, the herbicidal effect of the composition and its phytotoxicity for rice are evaluated.

    with powder), various cultures. The concentration of the compound in the soil is 3, 10, 30 and 100 ppm, calculated on the dry soil, and the seeds are grown for 20 days. Then investigate damage to agricultural crops. The results are shown in table 6.

    The weight of the air-dried ground parts was determined by collecting only the ground parts of the plants, followed by drying them for 3 days in a room with good air circulation, measuring the weight of dry ground parts and calculating the percentage, calculated as the air dry weight in the untreated batch.
    At doses of 2.5 and 5 kg / ha, a noticeable herbicidal activity appears at a depth of 0 to 0.5 Cm from the soil surface, but no activity is noted at a depth below 0.5-1 cm. This indicates that a resistant herbicidally formed layer 0.5 cm from the soil surface
    Example. 12 coats of vinyl chloride resin, each of which has a height of 0.5 cm and a diameter of 10 cm to form a ring structure, are combined and filled with soil for rice. The structure is placed in a pot at a depth of 15 cm and filled with water to a level of 13 cm. Compound No. 138 (wettable powder) is then applied in doses of 1 and 2 kg / ha. Remove the water from the pot using a siphon so that a drop in the water level of 3 cm is obtained within 24 hours. The water level is maintained 3 cm above the soil level. After 48 h, soil samples were taken from each layer after 0.5 cm from the soil level and placed in Petri dishes. Pre-germinated millet seeds are sown there. After 15 days, the air-dry weight of the ground parts is determined.
    The results are presented in Table.
    Table 9
    As can be seen from these results, at a dosage of 2 and 1 kg / ha, herbicidal activity in the soil inside the 0-0.5 cm layer was established, but there was no herbicidal activity in the layer of 0.5-1 cm or below. Consequently, rice plants transplanted to a depth of 0.5-1 cm or deeper do not suffer damage.
    Example 8. Experimental sites were identified, each with an area of 2 m in a grassy field (5 years after formation) and compound No. 138 (wettable powder) was sprayed uniformly onto these sites at a dose of 1000 l / ha. This test was performed from mid-mid to mid-June in order to control already grown plants.
    The results are shown in Table. 10. Table 10 Example 9. A comparative experiment with a known herbicide lj was carried out under the conditions of example 1 to
    2,3,6-trichloro-5- (trishkala ratings similar to example 1.
    The results of the experiments indicate a high efficiency of the proposed herbicide composition. It allows you to successfully fight against different types of weeds, without damaging agricultural crops. method of tillage after flooding. The results of the experiment are presented in table. 11.
