Insecticidal composition

Abstract

The invention relates to an insecticide composition. The insecticidal composition comprises, by weight, 10-20 parts of destruxins, 35-70 parts of avermectin, 1-6 parts of azadirachtin, 2-8 parts of an emulsifier, 45-80 parts of an organic solvent and 12-30 parts of a cosolvent. By compounding destruxins, avermectin and azadirachtin which have different insecticidal modes and insecticidal objects, a new compound insecticide can be obtained. According to the insecticidal composition, insecticidal spectrum can be broadened, and insecticidal efficiency is enhanced. The insecticidal composition is beneficial to delay generation of pest resistance to insecticide, is effective on anti-avermectin insects and is environmentally friendly.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to an insecticide composition. Background technique [0002] Pesticides are medicines mainly used to control agricultural pests and urban sanitation pests. It has a long history of use, large dosage and many varieties. For a long time, frequent pests and diseases have become an important reason restricting the development of agriculture in my country. The economic losses caused by pests and diseases are more than 100 billion yuan every year, and the affected area has a tendency to increase year by year. [0003] Metarhizium anisopliae is a broad-spectrum entomopathogenic fungus, which is widely used in the control of various agricultural, forestry, animal husbandry and health pests. The research and application of Metarhizium anisopliae to control agricultural and forestry pests has a history of more than 100 years. In the past 20 years, more than 300 kinds of pests have be...

AI Technical Summary

Problems solved by technology

The long-term use of a variety of chemical agents has resulted in an increase in the amount of pesticide residues in agricultural and forestry land, resulting in restrictions on the trade of various products in the international market, and the increase in the resistance of pests to pesticides and the killing of natural enemies by pesticides have also led to the increase in the amount of pesticides used and Increased frequency of application, often leading to recurrence of a pest
