Description

Technical field: [0001] The invention relates to a pesticide, in particular to an insecticidal pesticide using neem as a raw material and a preparation method thereof. Background technique: [0002] Pesticides are mainly used to control agricultural pests and urban sanitation pests. It has a long history of use, large dosage and many varieties. In the 20th century, with the rapid development of agriculture, pesticides greatly increased agricultural output. However, almost all pesticides seriously alter the ecosystem, most are harmful to humans, and others are concentrated in the food chain. We must strike a balance between agricultural development and the environment and health. [0003] Botanical pesticides are a branch of pesticides. It refers to the plant-derived preparations that use the stable active ingredients contained in plants to use the recipient plants in a certain way to prevent or reduce the damage of harmful organisms such as diseases, insects, and weeds...
