Abstract

The invention discloses a novel insecticidal suspending agent containing azadirachtin and neem oil, belonging to the technical field of pesticides, and solving the problems of bad prevention and control effects, higher and higher usage amount, as well as higher and higher prevention and control concentration of chemical pesticides, more and more obvious pesticide residue on crops, and obvious quality decline of agricultural products in the prior art. The novel insecticidal suspending agent containing azadirachtin and neem oil disclosed by the invention is composed of the following components in percentage by weight: 0.1-3% of azadirachtin, 3-10% of neem oil, 5-20% of chlorantraniliprole, 2-5% of a dispersing agent, 2-4% of a thickening agent, 3-8% of an antifreezing agent, 0.2-0.6% of a defoaming agent, 2-4% of a wetting agent, 1.2-3.8% of an antimicrobial agent, and 60-80% of water. The invention further provides a preparation method for the suspending agent aforementioned. The suspending agent disclosed by the invention is prominent in prevention and control effects on pests, capable of delaying the generation of the drug resistance of the pests, and avoiding the awkward situation of increasing the dosage of chlorantraniliprole to improve effects after long-time use of chlorantraniliprole, thus reducing residues, promoting environmental protection and improving the quality of agricultural products, and remarkable in social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a new insecticidal suspension containing azadirachtin and neem oil and a preparation method thereof. Background technique [0002] Chemical pesticides contain a large amount of organic solvents, which have brought serious pollution to the natural environment while making great contributions to agricultural harvests. With the improvement of environmental protection laws and regulations, the call for reducing pesticide pollution is becoming stronger and stronger. And the biggest problem in the current pesticide market is that the increase in resistance to chemical pesticides leads to poor control effects. The amount of use is increasing, the concentration of control is increasing, and the effect is relatively poor. For example, the widespread use of emamectin benzoate for 10 years In addition, pesticide residues in crops are becoming more and more prominent, and the...
