Problems solved by technology

However, the development cost of new active ingredients is high, the development cycle is long, and it can never keep up with the speed of pest resistance
Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

Abstract

The invention belongs to the technical field of agricultural pesticides and particularly relates to a clothianidin and tebufenozide compound insecticidal composition. The clothianidin and tebufenozide compound insecticidal composition has the effective components of clothianidin and tebufenozide of which the weight ratio is 1:(4 to 8) and preferably 1:(5 to 7). The clothianidin and tebufenozide compound insecticidal composition consists of the effective components with different function mechanisms, the acting sites are increased to be conductive to overcoming and delaying production of pest drug resistance, and the insecticidal spectrum is broadened; the drug effect is greatly improved, the prevention time is long, field consumption of the effective components is reduced, the production and use costs are lowered, and pesticide residues and environmental pollution are reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural insecticides, in particular to a compound insecticidal composition of clothianidin and tebufenozide. Background technique [0002] Clothianidin is a neonicotinoid insecticide. It is a new type of insecticide with high efficiency, safety and high selectivity. Its action is similar to that of nicotinic acetylcholine receptors, and it has contact killing, stomach poisoning and systemic activity. It is mainly used as an insecticide for preventing and controlling aphids, leafhoppers, thrips, planthoppers and other pests of Hemiptera, Coleoptera, Diptera and some Lepidoptera on rice, vegetables, fruit trees and other crops. It has the advantages of broad spectrum, less dosage, low toxicity, long duration of drug effect, no harm to crops, safe use, no cross-resistance with conventional pesticides, etc. It has excellent systemic and osmotic effects, and is an alternative to highly toxic organic pesti...
