In the FO |) mules II-VJII R: --- 4 have the meaning indicated in formula I, lial means gall, gene, Me means alkali metal, in particular sodium or potassium, ammonium or aldylaminium group.

Tertiary amines, inorganic bases, alkali and alkaline earth metal carbonates and bicarbonates are used as acid binding agents. In the reaction of interaction, it is sometimes necessary to use catalysts, such as copper or copper chloride. Snobs 1a, 1b and 2 are carried out at a reaction temperature from -2 to + 130 ° C with a normal pressure of 3% solvent. Vyla xL

Suitable solvents for organic solvents include the ester of ester% G-like compounds, amideg, aliphatic, aromatic, and also halogenated hydrocarbons, intrils, dimethylsulfoxide, ketones, water.

Para. 1. Measurement. To a solution of 11.6 g of 4-point-4-chloro-isobenzene and 5.1 ml of triethylamine in 150 ml of absolute ether is added

at room temperature, 10.1 g of o-ethyl-S- (L) -propyl-thiosphosphoric acid chloride in 25 ml of absolute ether. The salt that has been separated out is filtered off and the mixture is mixed with 200 ml of ice water. The organic phase is separated, washed once with water and shaken twice with ice-cold with a 5% solution of caustic latr and washed with water until neutral. Then the ether phase is treated with activated carbon, filtered, dried and the solvent is evaporated. The residue is dried for 3 hours at 70 ° C and 0.1 mm Hg. Art. Get the connection

According to the above methods, compounds are prepared that are shown in Table. one.

B. Insecticidal gastrointestinal action: Spodcptera littoralis.

Acting in a similar way, but using cotton instead of potato bushes, and instead of larvae of the species Leptinotarsa decemineata, the larvae of the species Srodoptera littoralis (LS), repeat the experiment.

For each active principle, two bowls are used, then ground feed is placed in the bowls and covered with a copper mesh. After 3 days set the number of dead larvae in%. In the case of 100% destruction, after 8 start of the experiment, after each CJ-TOK displacement, another 50 fresh herbs were placed in each bowl and after 3 days a second assessment was made of the destruction achieved. The test results are given in D table. 4. Table 4

containing 200 or 100 ppm of the test substance, and the solution is allowed to drip drop by drop. Then, 5 experimental insects (Chilo suppressalis species in the Lg stage) are placed in each vessel and the treated plants are planted on top.

D. Acarid action of Rhipicephalus bursa (adults and larvae) and Boophilus microplus (RR-sensitive and RR-hardy larvae).

10 adults or approximately 100 larvae of the Rhipicephalus bursa species or 100 OR-sensitive or 100 OR-resistant (stability refers to the compatibility of the diazinon) larvae of the Boophilus microplus species are placed into a glass tube and immersed for 1-2 min. Of an aqueous emulsion containing 100 , 10 or

Evaluation of the destruction achieved, in%, is made after 5 days. This is carried out at 24 ° C and 70% relative air humidity.

In the case of adults, an assessment of the destruction achieved was made after 2 weeks, and in the case of the larvae of both species after three days. Each experiment (developmental stage or endurance — type — concentration of active principle) is repeated twice. The test results are given in table. 6
