Description

Biogenic pesticide for resisting diseases and insect pests of solanaceous vegetables
Technical Field
The invention belongs to the technical field of pesticides, and particularly discloses a biogenic pesticide capable of helping solanaceous vegetables to resist plant diseases and insect pests.
Background
Solanaceous vegetables refer to vegetables of solanaceae with berries as main edible organs, and are main summer vegetables throughout the country. However, the same diseases and insect pests can be caused by similar environmental conditions such as temperature and humidity in the seedling stage and the adult stage of the solanaceous vegetables. According to incomplete statistics, the current use situation of the registered pesticides of solanaceous vegetables is still that traditional chemical pesticides are used mostly, and the pesticide mainly takes a bactericidal formulation as a main component. The chemical pesticide makes great contribution to improving the crop yield and solving the survival problem of human beings. But also leave a plurality of problems of high toxicity, high residue, high pollution and the like in the production and use processes. Meanwhile, vegetable growers often do not realize the risk of using highly toxic pesticides on vegetables in pursuit of high efficiency of pest control. Therefore, the main contradiction between the disease and insect damage of the solanaceous vegetables and the overproof pesticide residue is overcome, the important bottleneck for solving the quality problem of the solanaceous vegetables is still solved, and the problems also influence the healthy development of the vegetable industry.
At present, the development of novel green, high-quality, high-efficiency, low-toxicity, low-pollution and even pollution-free pesticides becomes the development direction of modern pesticides. The biogenic pesticide refers to pesticide which directly utilizes bioactive substances generated in living organisms or in a biological metabolism process or extracts substances from organisms as pests and diseases, and comprises plant sources, animal sources, agricultural antibiotics, living microorganisms and the like. Many medicinal plants produce various different secondary metabolites for resisting the invasion of plant diseases and insect pests, the metabolites can play the same role as chemical pesticides, and can be degraded under natural environmental conditions after being used due to the fact that the metabolites are derived from organisms, so that the problem of pesticide residues is greatly solved, and the biological pesticide has the characteristics of low toxicity, safety to natural enemies of pests and the like, and meanwhile, the chemical components are complex and are not easy to generate drug resistance. Therefore, the biogenic pesticide becomes a pollution-free pesticide which is ideal for solving the problem of chemically synthesized pesticide 3R. Based on the above practical situation, there is a need for a biogenic pesticide which can achieve the purposes of reducing the pest and disease attack and pesticide residue of solanaceous vegetables and reducing environmental pollution on the basis of wide disease prevention and treatment.
