Compound pesticide for effectively preventing and controlling cotton aphids and application thereof

Abstract

The invention relates to a compound pesticide for effectively preventing and controlling cotton aphids and an application thereof. The active ingredient of the compound pesticide for effectively preventing and controlling cotton aphids provided by the invention includes dipropyl cyclamate and thiamethoxam at mass ratio of 1:(4-15). The invention aims to solve the technical problem of drug resistance of cotton aphids. On the basis of a large amount of indoor toxicity screening, the invention finds that the compound of dipropyl cyclamate and thiamethoxam is capable of effectively delaying the generation of drug resistance of cotton aphids and has a synergistic effect for preventing and controlling cotton aphids, so that a new effective preventing and controlling method is supplied for comprehensively controlling insect attacks of cotton aphids. According to the invention, the dosage of pesticides is reduced, so that the cost is lowered, the environmental pollution is reduced, the resistance control on cotton aphids is benefited and the popularization and application of the compound pesticide have huge economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a compound insecticide for effectively preventing and controlling cotton aphids and an application thereof. Background technique [0002] Cotton aphids (Aphis gossypii) is an important pest worldwide, which can feed on more than 700 kinds of plants including cotton and cucumber. Cotton aphids cause harm mainly by directly feeding on plant sap and spreading plant viruses, causing huge economic losses to agricultural production. Cotton aphid has the characteristics of fast reproduction, large population, and severe damage. For a long time, chemical control has been the main means of control of cotton aphid in my country. Due to the long-term and extensive use of chemical pesticides, cotton aphids have developed high levels of resistance to various insecticides such as organophosphates, carbamates, pyrethroids, and neonicotinoids. [0003] Long-term use of pesticide...

Problems solved by technology

However, with the frequent use of neonicotinoid insecticides such as imidacloprid and acetamiprid in recent years, the resistance of cotton aphids to such insecticides has become increasingly serious.
