Abstract

The invention belongs to the technical field of pesticides and relates to a compound pesticide containing pymetrozine. The pesticide comprises the following components in percentage by weight: 1-50 percent of pymetrozine, 10-60 percent of isoprocarb and 0.5-10 percent of agricultural organosilicon. The components are prepared into wettable powder or a suspending agent or a water dispersible agent with other auxiliary agents or carriers. Through practical tests, the pesticide has obvious preventing and treating effects on rice planthoppers of rice and aphids on vegetables. Compared with a single chemical insecticide, the compound pesticide can reduce the effective dosage of the pesticide, delay the generation of drug resistance and reduce residues on agricultural product, and compared with a pesticide without the agricultural organosilicon, the compound pesticide can obvious improve the preventing and treating effects.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a compound pesticide containing pymetrozine. Background technique [0002] Due to the extensive use of chemical insecticides, unreasonable application techniques, improper use of pesticide varieties, and the killing of non-target organisms, since the 1970s, rice planthoppers, fruit trees, vegetable bemisia tabaci, and aphids have successively appeared. Pest-sucking pests such as imidacloprid and buprofezin have developed resistance to imidacloprid, buprofezin, etc. and have become rampant again. Especially since 2000, the rice planthoppers in the Yangtze River Basin, South China, Southwest and other vast rice areas have caused disasters, and fruit tree and vegetable aphids The difficulty of prevention and control is also increasing year by year. At present, new pesticide varieties such as pymetrozine and nitenpyram are promoted in production. They are well received by plant prot...
