Description

technical field [0001] The invention relates to a plant insecticide, in particular to a plant insecticide containing matrine and its preparation method and application. Background technique [0002] With the improvement of people's living standards in our country and the development of science and technology, people have higher requirements for basic necessities of life, especially for food safety. People are increasingly favoring green grains and fruits and vegetables that are pollution-free and pesticide-free. However, due to the long-term use of chemically synthesized highly toxic and high-residue pesticides in the prevention and control of diseases and insect pests in my country, it has caused varying degrees of damage to the ecological environment, and has also caused increasingly serious harm to the food that humans and animals depend on for survival. [0003] Based on the above background, in order to meet people's increasing requirements for food safety, it is neces...
