Abstract

The invention belongs to the field of biological pesticides, and mainly discloses a pollution-free biological compound pesticide and a preparation method thereof. Shell, Sophora flavescens, Bacillus subtilis, Bacillus licheniformis, Streptomyces chamotis and Streptomyces aureus. The present invention not only greatly improves the bacteriostasis effect of biological pesticides by adding Chinese herbal medicine extracts such as Hyacinth hyacinthus and Rhizoma Sinensis to the pesticide, but also the Chinese herbal medicine extract has no poisonous effect on humans and animals, so that there is no need to worry about causing harm to humans and animals when the present invention is used. adverse effects. The biopesticide of the present invention has the characteristics of high efficiency, environmental protection, no secondary toxicity, not easy to produce drug resistance, no residue, no pollution, maintenance of ecological balance, and no pollution. It is an important guarantee for realizing green ecological agriculture and green enterprises. Broad prospects.

Description

technical field [0001] The invention belongs to the field of biological pesticides, and mainly relates to a pollution-free biological compound pesticide and a preparation method thereof. Background technique [0002] There are mainly agricultural control methods, chemical control methods and biological control methods in the prevention and control of common flower diseases and insect pests. At present, the more traditional agricultural control plus chemical control mode is mainly adopted, and chemical pesticides are generally used, and pests and diseases are cut off branches and leaves. However, the long-term and large-scale application of chemical pesticides can easily cause serious consequences, such as the development of drug resistance, the destruction of ecological balance, and environmental pollution. Especially for ornamental flowers, tourists are close to them, and their ornamental properties and pesticide hazards coexist, threatening the health of tourists. At the ...
