Description

Suitable bases include sodium hydride (but not in the case of using a hydroxylated solvent or diluent), carbonates and alkali metal hydroxides. The reaction temperature depends on the choice of reagents, solvent, diluent and base. When using dimethylformamide and sodium hydride, the reaction proceeds at a temperature of from -10 to + 30 ° C, but other higher temperatures (up to 100 ° C) can be used if other bases are used.

The method consists in dissolving or dispersing a reagent having an amino group in a solvent or diluent in the presence of a base, and allowing the base to react with the reagent to remove the proton from the amino group, then the second reagent is added. After completion of the reaction, the product is isolated by diluting with a diluent in which the product is insoluble, for example with water. The product is then separated by filtration and recrystallized from an appropriate solvent or mixture of solvents to produce a night of pure substance.

The forms of application of the compounds of formula I are ordinary: powders, granules, grains, solutions, emulsions.

The composition may contain, in addition to the diphenyl amino compounds of the formula I, also one or more other compounds having biological activity, for example insecticides, fungicides and acaricides. They may also contain one or more stabilizers, such as epoxides, as well as additives to improve the dispersion, adhesion strength and resistance to rain on the treated surface.

Example 1. The compound is applied in the form of a liquid preparation containing 0.1%.

by weight of the compound, except for experiments with Aedes aegypti, where the preparation contains 0.01% by weight of the compound in a mixture of solvents containing 4 vol. including acetone and 1 vol. including diacetone alcohol. The solutions are then diluted with water containing 0.01% by weight of a wetting agent Lissapol NX to the desired concentration of the compound.

The test method for each of the pests is the same and consists in the treatment of the pest or the host plant,

or both necessary drugs

and in determining pest mortality in

period from 1 to 3 days after treatment.

The results of the experiments are given in Table. one.

Table 1

Note. Contact experience means that you have harmed and the environment has been treated, and residual experience means that the medium was treated before infection by the pest.

The definition of mortality is carried out on the scale from 0 to 3, where O is less than 30% of the destruction;

1-30 - 49% destruction;

2- 50-90% destruction;

3- over 90% of the destruction.

Example 2. A composition containing an aqueous solution or suspension of a test compound is sprayed onto the foliage of an uninfected plant; In addition, plants are wetted with a composition. The composition for spraying and wetting contains 50 ppm of the test compound. After spraying and wetting the soil, the plants are infected with a disease that must be destroyed, along with control untreated plants. After a few days, the percentage of the disease is visually determined.

Example 3. French bean plants in the first leaf stage, infected with the red mite Tetranychus telarius, are sprayed with a composition containing different amounts of the active ingredient. The lowest flow rate sufficient to completely kill the mites after 3 days is 10%.

LDioo was found to be 10 pp for male rats.

Example 4. Adult male M. Regicae is sprayed under a modified Potter column. Aphids are sprayed on

from disease of the control plants that were not treated with the tested compound.

The results are presented in table. 3. Example 5. Muzus persicae on Chinese cabbage is sprayed under a modified Potter column. Consumption 4 ml per unit, pressure 0.7 atm. After spraying, the aphids are transferred to open glass rings treated with a fluon. The results are shown in Table. four.

Example 6. Chinese cabbage bushes are sprayed in a modified Potter column. An untreated Muzus regenUntreated ay on the treated leaves is placed on the still wet treated sheet.

Example 7. Field experiments.

In these experiments, fruit-bearing blocks are sprayed with large volumes (more than 100 l / ha) of various preparations. The leaves of the blond are then inspected at various intervals and the populations of mites or insects are counted.

In all experiments, no undesirable phytotoxicity or damage to the fruit is obtained.

The number of ticks before treatment and the degree of tick killing on 40 leaves are determined.

In addition, it was determined that in order to kill 50% of male rats, 100 mg / kg of active substance per kg of composition were needed.

Thus, the proposed compounds have a high insecticoacaricidal fungicidal activity at low concentrations.
