Pyridaphenthion-avermectin compound agent

Abstract

The invention relates to a double crossing pesticide agent which is prepared by parathion avermectin as the active ingredient and appropriate catalysator and solvent, it is mainly used for the control of rice stem borers, particularly play a excellent control effect to the antagonism bivoltine borer, it can replace the prior nereistoxin insecticide monosultap (double)and the organic phosphorus insecticide phentriazophos which insecticidal effect reduces because of insecticide resistance, it also can be used with phentriazophos, double crossing agent, fluorine insert nitrile alternatively to delaying the development of resistance. So it is the ideal double crossing pesticide agent for control the antagonism bivoltine borer.

Description

technical field [0001] The invention relates to a pesticide insecticide, especially a pyridazinfos-abamectin compound agent, which belongs to a new type of high-efficiency and low-toxicity insecticide, and is a new type of compound insecticide specially used for preventing and controlling rice borers. agent. Background technique [0002] my country has a long history of rice planting and its distribution is very extensive. In recent years, the planting area is about 33 million ha 2 , with an annual output of 180 million tons of rice, accounting for 45% of the country's total grain output, and is the most important crop to ensure my country's food security. For more than half a century, stem borers have been an important pest of rice in my country. In the past decade or so, the number of rice borers in the Yangtze River Basin has risen sharply and outbreaks have occurred year after year, seriously affecting my country's food safety production. The national annual occurrenc...
