Abstract

The invention belongs to the technical field of plant disease control, and concretely relates to a botanical pesticide for controlling tomato virus diseases, and a preparation method thereof. The botanical pesticide comprises, by weight, 5-15% of rheum officinale, 5-15% of isatis root, 5-15% of garlic, 3-7% of croton seeds, 4-6% of Seed or fruit of Thickfruit Millettia, 5-15% of Agropyron cristatum, 5-15% of Chinese prickly ash, 15-25% of ethanol and 15-25% of purified water. All raw materials are from plants, and the pesticide has the advantages of simple preparation method, low cost, no pollution and no residual, can dispel aphids, kill aphids and treat virus diseases, can control the tomato virus diseases in many ways, and has an extremely good control effect.

Description

technical field [0001] The invention belongs to the technical field of plant disease prevention and control, in particular to a botanical pesticide for preventing and treating tomato virus diseases and a preparation method thereof. Background technique [0002] Tomato virus disease is a common disease of tomato, and it is also one of the heaviest and most difficult diseases to control. Infected fields generally reduce production by about 20%, and severe diseased fields can reduce production by more than 60%. Tomatoes with viral diseases not only reduce yield, but also decline in quality, which seriously affects economic benefits and is a major obstacle in tomato production. At present, the prevention and control of tomato virus diseases mostly adopts comprehensive control measures, such as: selection of disease-resistant varieties, implementation of non-toxic seedlings, early control of aphids, and cutting off the transmission of viruses. Once Tianjian gets sick, it is basi...
