Problems solved by technology

However, long-term single large-scale use is likely to produce drug resistance, thereby reducing the life cycle of the product. In order to delay the emergence of drug resistance, compounding with chemical pesticides may be a good choice, but the compounding of biological source pesticides and chemical pesticides may cause Its environmental compatibility is questioned by opponents of chemical pesticides

Abstract

The invention relates to a pesticide preparation and process for preparing it, wherein the preparation mainly comprises nimbin and methylamino avermectin as t he active ingredients, and the preparation consists of mixing 0.05-20 wt% of nimbin extractive and 0.1-15 wt% of methylamino avermectin, at the presence of various auxiliary agents, preparing agricultural chemicals including emulsion oil, wet powder (WP), water granules (WG) and microcapsule suspending agent (CS).

Description

technical field [0001] The invention belongs to an insecticide compounded with plant-derived pesticides and microorganism-derived pesticides, and in particular relates to a compounded pesticide preparation of azadirachtin and emamectin and a preparation method thereof. Background technique [0002] With the large and unreasonable use of chemical pesticides, especially high-toxic and high-residue products, while protecting stable and high-yield crops, it will inevitably cause environmental pollution, excessive pesticide residues in agricultural products, and increased resistance of crop diseases, insect pests and weeds. In response to these problems, people are increasingly calling for the development and use of green bio-pesticides, and the direct processing and utilization of natural products has become one of the hot spots. Through research, the invention of compounding azadirachtin (extract) and emamectin to process it into a pesticide preparation with stable physical and...
