专利说明:

This invention relates to chemical means of protecting plants against pests, specifically to an insecticidal agent.
The purpose of the invention is to increase the effectiveness of the agent.
The compounds used in the insecticidal agent are new and can be obtained, for example, by reacting the phosphonium or phosphoton salts of formula (l) or (II) first with a base in the presence of an inert solvent to carry out the esterification reaction, and then with a compound of the formula (III) with the formation of compounds of the formula (lV) n as a result of their reduction to the target products:

PRI me R 1. A. Mixed may 20, h. active compound, 75 wt.h. isophorone and 5 ma.ch. a combined calcium phenylsulfonate emulsifier and a fatty alcohol polyglycol ester.
B. In a similar way, a composition of 2.0 mph is obtained. active compound and au ma.ch, acetone.
Example .. Insecticidal activity in the soil against the eggs of the worm larvae in the maize roots and the growth of the maize roots.
The compounds are administered in an amount of 64 and 25 ppm, and the emulsion concentrate obtained in Example 1 is diluted with water to the desired concentration. 20 ml of prepared doses of biologically active substance are poured into plastic flower pots (mm), which are filled with 200 ml of soil, and to a depth of about 1 cm the eggs of the redroot and cornworm roots are introduced into the soil. After this, the pots are exposed to a greenhouse for a period of 14 days under normal conditions and at a temperature of 25 ° C. The evaluation criterion is the calculation of mortality for 14 days after the start of the experiment and comparison with the untreated control, as well as the percentage increase in the mass of the maize root after 14 days compared to the untreated control sample. The results are shown in table 1.
Example The action of the preventive treatment of the leaves in relation to the brown rice cicada (N / Iaparvata Lugens Stal).
i In a warm i greenhouse, rice plants (about 15 pieces in a pot) are immersed in a water preparation containing 1bP, 64. and 25 ppm of biologically active substance. After drying, the rice plants thus treated are immediately infected with larvae, kami — one-day and six-day N / Iaparvata Lugens and kept for 2 days at 28 ° C in the climatic chamber. The evaluation criterion is the calculation of mortality for 48 hours, from the beginning of the experiment and comparison with untreated control specimens, the results are shown in Table 2. Example 4. Prophylactic treatment of leaves against brown rice larvae (L-C). cicadas (N / Iaparvata Lugens Stal).
In a warm greenhouse, rice plants (about 15 pieces in a pot) are immersed in water preparations containing
64, 25, 10 and 4 ppm of the biologically active substance. After drying, the rice plants thus treated will be infected with 80-100 N / Iaparvata Lugens larvae in each pot.
For 2 days, stay in a climate chamber at 2–8 ° C and a relative humidity of 60%. The evaluation criterion is the calculation of mortality within 48 hours after the start of the experiment compared to untreated control samples. The results are shown in table 3.
Example 5. The action of the preventive treatment of leaves against Nepnotettix cincticeps.
In the heat greenhouse, rice plants (about 15 pieces in a pot) are immersed in water preparations containing 5 25, 1P and 4 ppm of biologically active substance. After drying, the rice plants thus treated will be infected with Nepnotettix cincticeps and kept for 2 days in a greenhouse at 28 ° C and a relative humidity of 70%. The criterion for evaluating the effect is the calculation of mortality 48 hours after the start of the experiment compared with untreated control samples.
The results are shown in table 4.
