Composite chemical for preventing and treating vegetable virus diseases

Abstract

The invention discloses a composite chemical for preventing and treating vegetable virus diseases. The composite chemical comprises, by weight, 1-3 parts of potassium manganate, 1-3 parts of 1 millionunit streptomycin sulfate for injection, 2-8 parts of quick lime, 1-8 parts of copper sulfate, 1-3 parts of chitosan, 2-8 parts of lentinan, 1-4 parts of oligosaccharins, 1-2 parts of lauryl sodium sulfate wetting agent and 80-100 parts of traditional Chinese medicine additives. A preparation method of the traditional Chinese medicine additives include: mixing fructus amomi, radix curcuma, curcuma zedoary, radix curcumae and cardamom, crushing, sieving, adding an ethanol solution to perform impregnation under room temperature, filtering, performing vacuum concentration on the filtrate and recycling the solvent to obtain extract, adding bentonite, glycerin fatty acid ester polyoxyethylene ether, evenly mixing, drying to constant weight, crushing, and grinding to obtain the traditional Chinese medicine additives. The composite chemical is capable of promoting the growth of vegetable seedlings, quick in action, capable of increasing vegetable seedling virus resistance to allow the vegetable seedlings to grow normally, easy to degrade, low in toxicity, ecological and environmentally friendly.

Description

technical field [0001] The invention relates to the field of vegetable planting, in particular to a composite medicament for preventing and treating vegetable virus diseases. Background technique [0002] Plant virus disease is a kind of important disease that harms crops. It is called plant cancer because of its serious harm and difficult control. It has caused huge losses to agriculture all the year round, and the annual crop loss in the world is as high as billions of dollars. In recent years, plant virus diseases have become more and more harmful, especially to cash crops. Such as cruciferous vegetables such as cabbage, cabbage, radish, and melon and vegetable plants such as pumpkin, zucchini, and loofah. [0003] At present, there are 909 species of plant viruses in the world, and more than 100 species have been reported in my country. Most commercial crops will be harmed by virus diseases, and vegetable crops are the most seriously affected. Some or all of the plant...

Problems solved by technology

Some or all of the plants grow abnormally after the vegetables are infected with viruses, which affects the quality, reduces the yield, and even leads to extinction. Moreover, there are many types of vegetable virus diseases, and it is difficult to control them. Therefore, it is very urgent to choose an effective agent for the prevention and treatment of vegetable virus diseases.
