Description

technical field [0001] The invention relates to the technical field of a biological insecticide, in particular to a biological insecticide. Background technique [0002] During the growth and development of crops, they are vulnerable to various pests, especially vegetable crops, which have a wide variety of pests and serious damage, such as aphids, diamondback moths, and cabbage caterpillars. For a long time, chemical control has been the main control method for crop diseases, that is, the application of chemical insecticides. However, with the long-term use of chemical insecticides, insect pests are prone to develop drug resistance, resulting in a decline in the control effect. Frequent use of chemical insecticides has caused Seriously exceeding the standard pesticide residues, destroying the ecological environment, directly affecting food safety, it has long violated the body of animals and humans, affecting the ecological balance and human health. [0003] At the same ti...
