Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a botanical insecticide and a preparation method thereof. Background technique [0002] At present, in vegetable cultivation, chemical pesticides and insecticides are usually used to prevent pests, and the environmental pollution caused by the extensive use of chemical pesticides is becoming more and more serious. At the same time, the use of chemical pesticides and insecticides causes various pests to develop drug resistance and resistance, which increases the difficulty of control and even causes control failure. In addition, chemical pesticides pose a threat to beneficial organisms because they are not selective. Moreover, many chemical pesticides are non-degradable or difficult to degrade, and are easy to accumulate in animals and plants, resulting in the enrichment of pollutants. With the improvement of people's living standards, the requirements for the quality o...
