Low-pollution pesticide for green soy bean planting

Abstract

A low-pollution pesticide for green soy bean planting comprises at least four solutions, wherein the solution 1 is a microemulsion of tephrosia vogelii stem and leaf extract, the solution 2 is an aqueous solution of amorpha fruticosa seed extract, the solution 3 is an aqueous solution of tripterygium wilfordii root extract, and the solution 4 is one or a mixture of more of an aqueous solution of acoptis rhizome extract, an aqueous solution of a phellodendron bark extract and an aqueous solution of a stem endothelium extract of berberis julianae, and further comprises one or more of garlic liquid, chili liquid, plant ash liquid and sulfur soap liquid. According to the invention, the pesticide components are sprayed multiple times according to a certain amount and a certain period in the stages of sowing, seedling, flowering and fruiting of the green soybeans respectively, common diseases and insect pests of the green soybeans can be effectively restrained, the propagation speed of thediseases and insect pests is restrained; in addition, plant extracts are main raw materials in the pesticide, so that chemical reagent residues on the surfaces of the green soybeans are avoided, and the pesticide belongs to eco-friendly products.

Description

technical field [0001] The invention relates to the technical field of edamame planting, in particular to a low-pollution pesticide for edamame planting. Background technique [0002] Edamame, commonly known as soybeans and soybeans, is the seed of Papilionaceae soybean, an annual herbaceous crop, 30-90cm high, thick stems, square rhomboid; Hard hair; spring edamame is a vegetable soybean, also known as edamame, green edamame, and white edamame. It refers to soybeans with green pods that are received between the full grain period and the early ripening period. The pods are tender green. After the edamame matures, it is our Familiar soybeans. [0003] Edamame is rich in nutritional value. In addition to the nutritional value of soybeans, the content of various vitamins and minerals is also high. During the planting of soybeans, the control of diseases and insect pests (including rust, downy mildew, aphids, spider mite, bean pod borer, borer, etc.) The spread speed is fast,...

AI Technical Summary

Problems solved by technology

During the planting of soybeans, the control of diseases and insect pests (including rust, downy mildew, aphids, spider mite, bean pod borer, borer, etc.) The spread speed is fast, and if the prevention and control is neglected, it will bring immeasurable losses to the growers. The usual method in the prior art is to spray pesticides on a large area, but the pesticides used are basically synthesized from pure chemical substances, resulting in more pesticide residues on the surface of edamame. People's pursuit of green food is contrary to the concept, and at the same time, the surrounding environment and rivers are seriously polluted. Moreover, soybean pests and diseases are prone to drug resistance after multiple chemical treatments. Later control needs to increase the amount of pesticides or research and develop new pesticides. The cost and difficulty of control are further increased. increase
