Sanitary insecticidal composition containing flonicamid and application thereof

Abstract

The invention relates to a sanitary insecticidal composition and application thereof, the composition comprises an active component A and an active component B, the active component A is selected from flonicamid, and the active component B is selected from pirimiphos-methyl and fenitrothion. Through the synergistic interaction among the active components, the pesticide effect and pesticide effect stability of the composition are improved, and the composition is very suitable for preventing and controlling indoor and outdoor sanitary pests such as mosquitoes and flies and is environment-friendly.

Description

technical field

[0001] The invention relates to the field of hygienic insecticides, in particular to a hygienic insecticide composition containing flonicamid and its application. Background technique

[0002] Flunicamid is a high-efficiency and selective insecticide with good systemic property and strong osmotic effect. It can be transmitted from the root of the plant to the stem and leaf, and has a long-lasting effect. The latest research at home and abroad has found that flonicamid can interfere with the normal secretion of salivary glands by blocking the influx of potassium ions in the insect's inward rectifier potassium ion channel, thereby inhibiting the feeding behavior of insects; at the same time, it can also block the Kir channel Destroying the normal physiological function of insect Malpighian ducts will affect the secretion or excretion of honeydew, and eventually lead to the death of insects. Therefore, flonicamid can play an insecticidal role by affecting the no...
