Abstract

The invention discloses a synergic pesticide integrating synthetic pyrethroid and organophosphorus, which comprises (by weight percent) 0.1-20% of tetramethrin, ethofenprox, or bifenthrin, 10-7% of organic phosphorus insecticide, and balancing adjuvant. The pesticide can be used for controlling rice borer.

Description

technical field [0001] The invention relates to an insecticide for rice, in particular to a synergistic insecticide prepared by mixing a pyrethroid insecticide and an organophosphorus insecticide and its application. Background technique [0002] Rice is one of the most important crops in the world and one of the main foods for human survival. At present, the global planting area reaches 152 million hectares, and the output reaches 568 million tons. my country's rice planting area ranks second in the world. [0003] Improving the yield per mu of rice has always been the focus of people's research, and the main factors affecting the yield per mu of rice are genes (seed quality), planting level, and pest control. main factor of production. [0004] During the growth of rice, there are many kinds of pests and diseases that affect the growth and harvest of rice. Among them, rice stem borer, rice stem borer, rice stem borer, and rice leaf roller have the greatest impact on the g...
