Synergistic mite killing composition containing cyflumetofen and clofentezine

Abstract

The invention relates to a synergistic mite killing composition containing cyflumetofen and clofentezine, wherein the mass ratio of cyflumetofen to clofentezine is 10:1-1:10. The synergistic mite killing composition is suitable for preventing and treating various pest mites in agricultural field; combination of two active ingredients enables obvious synergic effect, thereby the preventing and treating effects can be enhanced, the pesticide application amount is reduced, the cost is reduced and the environmental pollution is reduced. The synergistic mite killing composition is in favor of resistance management of pest mites, and has large economic benefit and social benefit for popularization and application.

Description

technical field

[0001] The invention relates to an acaricidal composition, which uses cyflufenofen and tetrafenazine as active ingredients and is used for preventing and controlling agricultural pest mites. Background technique

[0002] Acarids, commonly known as red spiders, are pests of the class Arachnida. Most of the common harmful mites belong to the orders Eucarina and Acarina, and they are one of the important pests that damage various crops. Acarids damage the leaves, stems and flowers of plants, etc., and suck the stems and leaves of plants. They are common harmful organisms on fruit trees, cotton, nightshade vegetables and ornamental flowers. In the early stage, there are a large number of pinpoint-sized yellowish-brown dots on the front of the leaves, and in the later stage, the leaves shrink and fall off from the bottom to the top, resulting in a large number of fallen leaves. Sometimes it occurs from the leaves in the middle of the plant, and the leaves gradual...
