Description

(54) INSECTICIDE MEANS Temperature-Reactions may vary widely. Typically, the process is carried out at a temperature of -20 to b, preferably from -10 to. The starting materials are used in an equimolar ratio. An excess of one or another of the original substances does not give the best results. Preferably, to the reaction solution of 5-oxyimidazole in the presence of an acid acceptor, N, M-dimethylcarbamic acid chloride is added in drops so that the temperature of the reaction solution does not exceed 5 ° C. In the form of a solution, salts of 5-oxyimide can also be used. aralla .. At the end of the reaction, the usual processing is carried out, in which the reaction solution is alternately shaken with water and an organic solvent. The organic phase is dried and the solvent is distilled off. The compounds are obtained in the form of oils which, in part, do not lend to fit without decomposition. However, due to prolonged heating under reduced pressure to slightly elevated temperatures, volatile components can be removed from them and thus cleaned. A part of the compounds of the PELPP is in the form of crystals with a sharp melting point. Active ingredients may be contained in conventional preparations, for example, in solutions, emulsions, wettable powders, suspensions, powders, powdered preparations, foams, pastes, soluble powders, granules, aerosols, suspension and emulsion concentrates, powders for powdering seeds. , in natural and synthetic substances, prepared by the use of SHEDYDY-ASHYSHT G seed coatings, in preparations with combustible substances, for example in cartridges, cans, spirals for fumigation, etc., in preparations for distribution of the substance with extremely izkim volume. In addition, the effective rules can be concluded in polymers.-.--- -: ll. ..... Preparations are prepared by conventional methods, for example, by mixing the active ingredients with diluents, i.e. with liquid solvents, liquefied gases, found by Ttbd pressure, and / or with solid fillings, if necessary with the use of surface-active substances, i.e. emulsifiers and / or dispersants, and / or frothers. In the case of using water as a diluent, it is possible to use, for example, organic solvents as a spray of solvent solvents. The following are mainly used as liquid solvents:

645516 aromas, 1 as xylene, toluene, or alkylnaphthalenes, chlorinated / aromas or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane, or paraffins, such as oil fractions, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, for example acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, highly polar solvents such as dimethylformamide and dimethyl sulfoxide, as well as water. . By liquefied gaseous diluents or fillers are meant such liquids that are under normal temperature and pressure. Scientific research institutes are gaseous, for example, aerosol gases, like halogenated hydrocarbons, as well as butane, propane, nitrogen and carbon dioxide. Solid fillers are: natural stone flour, such as kaolin, alumina, talc, chalk, quartz, attapulgite, montmorillonite, or diatomaceous earth, and synthetic stone flour, such as highly dispersed silicic acid, aluminum oxide, and silicates. Solid fillers for granules of the owner of YUTS9 are crushed and fractionated natural stones, for example, calcite, marble, pumice, sepiselite, dolomite, as well as synthetic granules from inorganic and organic flour and granules from organic matter, for example, from sawdust, coconut shells, cobs of corn and tobacco stalks. Emulsifiers and / or blowing agents are, for example, non-ionic, and emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example, alkylaryl polyglycol ethers, alkyl sulfonates, alkyl sulfates, aryl sulfonates, alkyl esters. also hydrolysis of ata protein. Dispersants are, for example, lignin, spent sulphite woods and methylcellulose. The preparations may contain, agents -; adhesion promoters, for example carboxymethylcellulose, natural and synthetic powders, granular or latex-like polymers, for example gum arabic, polyvinyl alcohol, polyvinyl acetate. Preparations may also contain dyes, such as inorganic pigments, for example. Iron oxide, titanium oxide, ferrocyanine blue, and organic dyes, for example alizarin, azometallic phthalocyanine dyes, and

Micronutrients, eg salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

Example 1. Experience with M IJ Z U S persicote (contact action).

The preparation of the active substance before dropping forms cabbage leaves, which are strongly affected by peach aphids.

One day after spraying, the degree of killing is determined (in%).

100% means that all aphids were killed, 0% - not a single aphid was killed.

Active substances, the concentration of active substances, the duration of the experiment, the results, as well as the biological activity of the prototype are given in Table. one.

The preparation of the active substance is watered by leguminous plants, which are strongly affected by black bean aphids, so that the active substance enters the soil without spraying the leaves.

The active substance from the soil is absorbed by leguminous plants and thus goes to the affected leaves.

4 days after the administration of the preparation, the degree of killing (in%) is determined.

100% means that all aphids were killed, 0% - not one aphid was killed.
