Description

This invention relates to chemical protection agents for plants, namely, an insecticide-liver remedy based on 2-propipamine derivatives. An insecticide is known, the active substance of which is derived from 2-propinipamine I. Also known is the commercial, insecticide of which is active with 4-dimetypamino -; - 3,5-dimetypheny. # - N-Metip carbonate (dextran) 2j. However, these insecticides have insufficient activity at low concentrations. With the chain of research of new insecticidal agents, obzadak tsykh high insecticine .. life, the invention involves the use of derivatives 2 - propinkle amine compound obsh formulas (11 glue. their chlorides CHO in an amount of 1O-8O wt.%; compounds of formula (I) are obtained by reacting propargyptohyphenides of general formula C with M-substituted methylamines of the general formula R-CH2-HH-CH, using a solvent in the presence of an acid acceptor and processing acid reactions, Since it is desirable to have salts, R has the above meaning and Na represents a halogen atom, preferably chlorine or bromine. For the synthesis of the compounds used according to the invention, the reagents are reacted in approximately equimolar amounts. The following substances can be used as a solvent: , aliphatic and aromatic hydrocarbons. The reaction is carried out at a temperature between 0 ° and 100 ° C, but is best in the temperature range from room temperature to

boiling point of the corresponding reaction mixture.

Tertiary amines, for example, triethylamine ip N, W dimethylaniline, pyridine bases or suitable inorganic bases, such as oxides, hydroxides and carbonates of alkali and alkaline earth metals, are used to bind the hydrohalic acids.

As a rule, propargyphogenide is added in portions to the appropriate Substituted methylamine and hapogenhydrogen acceptor, however, the stability of the addition of reagents may also be replaced by the reverse.

At the end of the reaction, the hapogenic hydrogen mixture is separated by filtration and washed with an appropriate solvent. After removal of the solvent, the residue is subjected to fractionated distillation under reduced pressure and the reaction product is obtained as a colorless liquid.

The salts of the derivatives of 2 propinylamine, if necessary, can be fused by treating amines with ethereal solutions of the acids upon cooling.

To the compounds used according to the invention, other plant protection products and anti-pest agents can be added depending on the purpose of I.X. use.

The forms of use of the compounds of the formula (1) are conventional: powders, spraying agents, granules, solutions, aegulations or suspensions.

The case examples illustrate the high activity of the proposed compounds.

Example 1: The compounds used according to the invention are used in the form of aqueous solutions of salts or aqueous base emulsions, which are emulsion concentrates, of the desired concentration. This is done in a similar way with comparative agents; in the case of 2 " 2-benzylcarbamoyl) -3THnj-isonicotinic acid hydrazide, the compounds are dissolved in acetone and diluted with water to the desired concentration.

The active ingredients prepared in this way are dipped 2-3 times until the old clutch of Egyptian cotton shovel eggs is completely wetted, which are laid out on filter paper by the female butterflies, and until 4 days after treatment in a closed Petri dish.

Efficacy is assessed by the reduction in the appearance of new butterflies, expressed as a percentage, compared to untreated egg clutches. The results are shown in Table. one.
