(54) GERVICIDE COMPOSITION
The invention relates to chemical agents for controlling weeds and undesirable vegetation, and also to a herbicidal composition containing an active substance from the group of pyrazole derivatives and auxiliary components from among liquid or solid substances, surface active substances, etc. Herbicidal compositions based on pyrazole derivatives are known. These include, for example, a formulation based on 1,2-dimethylpyrazolium salts; j or a composition whose active ingredient is quaternary salts of 1,2-di-alkyl-3,5-difenshenyl pyrazolines. However, the known formulations of this type are not sufficiently effective for some types of weed plants. The aim of the invention is a new herbicidal composition based on a pyrazole derivative, which has an increased herbicidal activity. The above purpose is achieved by the use of a long-term pyrazole of the general formula s-r-j-BRV 11; . : iV R - hydrogen, acetyl, chloroacetyl, propionyl, phenoxycarbonyl, methoxycarbonyl, ztoxycar., bonil, formyl; R is hydrogen, is alkyl; R - CJ -GC-alkyl, 1-methoxy, propyl-2, 1-methoxybutyl-2, cyclopentyl, cyclohexyl, | norbornyl, bicyclo (2.2.1) -heptyl-X, phenyl, methylphenyl, methoxyphenyl, dimethoxyphenyl, chlorophenyl, dichlorophenyl , hydroxyphenyl, fluorophenyl, methylfluorophenyl, dkfluorophenyl, 1,1,2,2-tetrafluoroethoxyphenyl ;: R - acetyl, methoxycarbonyl; R is hydrogen, methyl; R and R together. MOPVT means pentamethylene and 3-oxapatemethylene; as well as salts of this compound, in an amount of from 0.1 to 95% by weight. The compounds according to the invention are prepared by various methods, for example, by condensation of aldehydes, ketones or derivatives of c6-ketocarboxylic acid with 3-amino-4-alkoxy-carbonyl pyrizols, followed by hydrogenation of the resulting Schiff base. Pyrazoles, acylated at positions 1 or 1, are obtained by acylation of 3-aminopyrazoles derivatives. Sol pyrazole derivatives of general formula I are obtained by reacting the corresponding substituted pyrazoles with acids in a solvent. The gyrazole derivatives according to the invention are in two isomers Hbtx forms R, .-. 5. Consequently, under a particular Formula, two isomers are always meant, the ratio of which is determined mainly by different substituents. Table 1 presents the compounds of general formula IV studied as active ingredients of the proposed herbicidal composition. the use of active ingredients is usual: solutions, emulsions, pastes, powders, etc. They are ready t. by known methods. . Experiments in the greenhouse are carried out in the following manner. For cultivation of plants, plants serve as plastic streams with a capacity of 300 cm, covered with clayey sand, containing about 1.5% of the area. test plants separately by type s.yut in pots. In the course of processing, before the occurrence of scenarios, the trunk began to be deposited by us usver: yust. non-means outside after aosev. For afofi, the chains of them are suspended from 1, t, or emulsigiruks in the vhad and are pulling to the ground through a small distribution of juvenile nozzles. After the application, the deer driver started up the mountains for a light sprinkling in order to stimulate the formation of plants and at the same time activate chemical substances. After this, the vessels are covered with transparent plastic covers until the plants grow. Such a coating promotes uniform germination of test plants, if chemicals do not interfere with this, and prevents evaporation of volatile active principles. In the case of plant care after the appearance of seedlings, they are grown in pots, depending on their bioform, up to a height of 3-10 cm. Pots are not covered with covers. They are installed in a greenhouse. At the same time, for warmer plants with heat-loving plants, warmer areas of the greenhouse (25–40 ° C) are diverted, while for plants in more moderate climates, places with a temperature of 15–30 s are chosen. The duration of the experiment is 4-6 weeks. During this time, plants are cared for and evaluated for their response to treatment with various substances. Table 2-15 shows the tested substances, the dosage of the active principle, the types of test plants. Evaluation is made on a scale from 0 to 100. At the same time, O means that the plant was not damaged or that it was OK, and 100 - that the plants did not germinate or that at least all the above-ground parts of the shoot were completely destroyed. v Compound numbers correspond to the numbers in Table 1. 11-salt experiments were carried out on small areas of clayey sandy soil with a pH value of 5-6 and humus content in Jl, 5%. Treatment of plants after decompression. Young mec: plants are processed early: stages of growth at a plant height of up to 5 rm. The flora of weed plants varies with the seasons (for example, weeds growing in spring, weeds growing). The substances are emulsified or suspended in water and applied to the plants with a sprinkler mounted on a self-propelled chassis and driven by the engine. In the absence of natural precipitation, the areas are subjected to artificial nodding in order to ensure seedling and plant growth. All experiments are continued for several weeks. Then they are evaluated on a scale from 0 to 100. Table 2-15 shows the results of the experiments.
