Problems solved by technology

Abamectin has the advantages of novel chemical structure, unique mechanism of action, and strong insecticidal activity, but its slow drug effect, relatively narrow insecticidal spectrum, poor stability and high production cost are also its obvious shortcomings.
[0005] The synergistic combination of pesticides is an effective measure to expand the control spectrum and improve the control effect. Although there are many insecticidal compositions that use emamectin benzoate and abamectin as one of the active ingredients, So far, there is no insecticidal composition report using both emamectin benzoate and avermectin as active ingredients

Abstract

The invention discloses an insecticidal and acaricidal compound containing emamectin benzoate and abamectin, which has higher synergy effect, overcomes and delays pest insect resistance to insecticide, enlarges preventing and curing spectrum, and has the advantages of quick insecticidal speed, low cost of medicine and the like. The compound is prepared by taking emamectin benzoate and adamectin as active components then preparing with proper pesticide adjuvants or carriers, and the weight ratio of the emamectin benzoate and the adamectin is 1-90:90-1. The compound of the invention is widely used for preventing and curing various pests and mites in crops, such as grain crop, rice, corn, vegetable, fruit trees and the like.

Description

technical field [0001] The invention relates to an insecticidal and acaricidal composition, in particular to an insecticidal composition with emamectin benzoate and abamectin as active ingredients. technical background [0002] The loss of crop yield due to pests and diseases of crops is immeasurable, and chemical control is the main way to control the occurrence of pests and diseases. For this reason, it is necessary to apply a large amount of pesticides for pest control every year to recover the loss of crop yield. In recent years, the harm of insect pests on crops such as rice, fruit trees, vegetables, flowers and various economic crops has become more and more serious, and due to the abuse of pesticides, the resistance of pests to pesticides has become more and more serious, causing pest control. The effect decreases every year. Therefore, there is still a need for pesticide varieties with better pest control effects. [0003] Emamectin benzoate (referred to as emamect...
