Abstract

A composite insecticide for preventing and eliminating the pests (yellow rice borer, striped rice borer, leaf rolling rice borer, plutella xylosteela, noctuid, etc) with high effect and low pollution contains proportionally abamectin, chlorfluazuron, assistant and solvent or filler.

Description

Technical field: [0001] The invention belongs to pesticides for preventing and controlling agricultural pests, and relates to a composite insecticide whose active ingredients are abamectin and chlorfluazuron. Background technique: [0002] With the rapid development of my country's national economy and the continuous improvement of people's living standards, higher and higher requirements are put forward for the quantity, quality and safety of agricultural products. However, in the past ten years, due to the high quality, high yield and diversification of rice, vegetables and other crops, as well as climate warming and the invasion of foreign pests, the occurrence of crop diseases and insect pests has generally increased significantly. Major pests such as rice leaf roller, rice borer, vegetable beet armyworm, Spodoptera litura, diamondback moth, and cabbage caterpillar frequently broke out. Among them, rice leaf roller and rice borer occurred in large numbers and broke out ...
