Abstract

The invention relates to an environment-friendly botanical insecticide and a preparation method thereof. The environment-friendly botanical insecticide is prepared from the following components in parts by weight: 5 to 10 parts of nicotine, 1 to 3 parts of alangium platanifolium extract, 1 to 3 parts of radix stemonae extract, 1 to 3 parts of wintergreen oil, 0.1 to 0.5 part of pesticide fertilizer slow release agent, 1 to 3 parts of Bituo microbial agent, 20 to 30 parts of solvent, 1 to 3 parts of cosolvent, 5 to 8 parts of emulsifier, 5 to 10 parts of dispersant, 1 to 5 parts of thickener, 1 to 3 parts of anti-freezing agent, and 30 to 40 parts of water. The environment-friendly botanical insecticide has the advantages that the effect of the botanical insecticide is high, the lasting period is long, and the drug resistance of pests is delayed; the good preventing and control effect to tea geometrid and cabbage caterpillar is realized, the hazard to plants is avoided, any harmful and side effect to the human body is avoided, and the hazard to the human body by the traditional pesticide is completely avoided.

Description

technical field [0001] The invention relates to an environment-friendly plant insecticide and a preparation method thereof, belonging to the field of pesticides. Background technique [0002] my country is a country with a large population and a shortage of arable land. Increasing grain production and farmers' income has always been the main goal of agricultural production. However, for agricultural production, the loss caused by crop diseases, insect pests and weeds can reach up to 70%, and 40% of the loss can be recovered through the correct use of pesticides. It can be seen that the use of pesticides to control diseases, insect pests and weeds is a necessary technical measure to reduce the production of agricultural products. As we all know, chemical pesticides have a good control effect on plant diseases and insect pests, but the environmental pollution caused by chemical pesticides and the harm to ecological balance are unavoidable facts for human beings. In contrast,...
