Abstract

The invention provides a plant source pesticide capable of preventing and treating potato virus disease and preparation method of the plant source pesticide, belonging to the technical field of prevention and treatment of plant diseases. The plant source pesticide is prepared from the following raw materials: rhubarb, radix isatidis, garlic, croton, thickfruit millettia, agropyron cristatum, pricklyash peel, ethyl alcohol and purified water by a process according to a certain ratio. All the raw materials are from the plants; the preparation method of the plant source pesticide is simple, the cost is low, and public hazard, residue and pollution are avoided; the plant source pesticide is capable of expelling aphid, killing aphid, treating the virus diseases, preventing and treating the potato virus disease from multiple aspects, and is relatively good in prevention and treatment 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 potato virus disease and a preparation method thereof. Background technique [0002] Potato, Solanaceae Solanum, an annual herb, also known as ground egg, potato, taro, potato, etc. Potato cultivation dates back to around 8000-5000 BC in southern Peru.
