Abstract

The invention provides an insecticidal composition. The insecticidal composition comprises insect pheromones, thiamethoxam and diflubenzuron. The results of the embodiments in the invention are as follows: after the insect pheromones, thiamethoxam and diflubenzuron are compounded, an indoor drug effect test result shows that composition has synergistic prevention and control effects on insect pests, and a result of field experiments shows that the synergistic effect even exceeds 50% when applied to imagoes and other target insects having certain migratory flight capability, especially in aviation plant protection.

Description

technical field [0001] The invention belongs to the technical field of pesticide production, and in particular relates to an insecticidal composition and its application. Background technique [0002] China is a large agricultural country, and it has been dominated by planting for thousands of years. Agriculture is the source of human food and clothing, the foundation of survival, the basis for the independence and development of other sectors, and the foundation of the national economy. Therefore, the development of agriculture will directly affect the development of the national economy. However, in agricultural production, the occurrence of plant pests often seriously affects the growth of crops, which in turn leads to a large reduction in crop yield and brings huge economic losses to growers. Therefore, effective control of crop pests is urgent to ensure food security and economic interests of growers. [0003] Thiamethoxam is a neonicotinoid insecticide developed by N...
