Avermectins and fenbutatin oxide-containing water suspending agent insecticidal pesticide and preparation method thereof

Abstract

The invention discloses an avermectins and fenbutatin oxide-containing water suspending agent insecticidal pesticide. A water suspending agent consists of the following components in percentage by weight: 5 to 60 percent of avermectins and fenbutatin oxide, 1 to 10 percent of dispersant, 0.5 to 5 percent of wetting agent, 0.1 to 1 percent of thickening stabilizer, 1 to 5 percent of antifreeze, 0.1 to 1 percent of defoaming agent and the balance of water, wherein the content ratio of the avermectins to the fenbutatin oxide is 1:1-50. The invention also discloses a preparation method for the water suspending agent insecticidal pesticide. The method comprises the following steps of: first, shearing the weighed avermectins, fenbutatin oxide, dispersant, wetting agent, antifreeze and water in a reaction kettle; then, grinding sheared materials and adding the weighed defoaming agent with grinding; and finally, adding the weighed thickening stabilizer and continuing shearing to obtain the water suspending agent insecticidal pesticide. The medicament of the invention can perform synergy on pests from a plurality of aspects so as to fulfill the aim of effectively controlling the pests by using low medicament dosage, and has the characteristics of low medicament cost, particularly good effect on killing citrus red mites and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a water suspension insecticidal pesticide containing abamectin and fenbutatin, and also relates to a preparation method of the insecticidal pesticide. Background technique [0002] Abamectin and fenbutatin are two commonly used insecticidal pesticides.

It is not easy to decompose at room temperature, and there is no decomposition phenomenon ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of this invention is to provide a kind of water suspension containing abamectin and fenbutatin to kill pesticides, which solves the limitations of simply using abamectin and fenbutatin that exist in the prior art; The amount is relatively large, leading to the problem that toxin residues have great side effects on food and the environment, and the use cost is high
