Problems solved by technology

However, the long-term and extensive use of chemical agents has led to the general resistance of stored grain pests to chemical agents on the one hand; on the other hand, some insecticides affect non-target insects, and some beneficial insects have been unintentionally eliminated, resulting in a sharp increase in secondary pests , resulting in catastrophic consequences; more importantly, the problem of chemical residues is becoming more and more serious, which not only causes serious environmental pollution, but also poses a huge threat to human health

Abstract

The invention provides a 5% S-methoprene wettable powder and a preparation method and application thereof. The wettable powder is mainly used for inhibition of grain storage insects. The 5% S-methoprene wettable powder is prepared from S-methoprene, a carrier, a surfactant, a dispersant and an anti-oxidant. The prepared wettable powder is nontoxic, green and environment-friendly, has high activity on target insects and a ppm-grade application concentration and is a novel green grain storage insect inhibitor.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a 5% S-methoprene wettable powder and its preparation method and application. Background technique [0002] Stored grain pests are the main factors that cause the loss of stored grain quantity, cause grain mildew, and reduce grain quality. At present, the control of stored grain pests in my country mainly relies on chemical agents. However, the long-term and extensive use of chemical agents has led to the general resistance of stored grain pests to chemical agents on the one hand; on the other hand, some insecticides affect non-target insects, and some beneficial insects have been unintentionally eliminated, resulting in a sharp increase in secondary pests , resulting in catastrophic consequences; more importantly, the problem of chemical residues is becoming more and more serious, which not only causes serious environmental pollution, but also poses a huge threat to human health.
