The fungicides recommended for vegetable diseases are those
In the process of growing vegetables, fungicides can not be separated, so which fungicides are recommended for use in vegetables? Today, Xiaobian and everyone share the recommended fungicides for vegetable diseases?
(l) Inorganic fungicides
Mostly processed from mineral raw materials, the price is cheap, the environmental pollution is small, the residual effect period is long, the toxicity to humans and animals is small, and it is not easy to cause resistance to bacteria, etc., but the efficacy is not high, and it is easy to cause phytotoxicity of crops. There are mainly Bordeaux liquid, stone sulfur mixture, copper ammonia, sulfur, copper oxychloride, basic copper sulfate and cuprous oxide.
(2) Organic fungicide
It is a synthetic organic compound pesticide with low dosage, quick effect and wide application, but it is easy to pollute the environment, easy to make disease resistant, and unsafe for humans and animals. Among them, organic sulfur fungicides mainly include dexamethasone, daisen zinc, mancozeb, antibiotics 402 (aicain) and thiram; organophosphorus bactericides mainly include ethyl phosphine; organic arsenic fungicides mainly Fumei arsenic and Tian'an; substituted benzene fungicides mainly include methyl thiophanate, carbendazim, toxic mycelium, chlorothalonil, benzenelite and soil dispersion; organic heterocyclic fungicides mainly include agricultural lining, rust rust, and flutter Hydantoin, sclerotia, quick-krin, Tecto and Leby.
(3) Antibiotic fungicides
These pesticides are non-polluting, do not kill natural enemies, are safe for humans and animals, and are not easy to cause resistance to harmful organisms, but the application range is narrow, the effect is slow, and the effect is unstable. Common fungicides are mainly agricultural anti-120, polyoxymycin (poly-mycin, Bao Li'an), agricultural streptomycin.
(4) Mixed type fungicide
There are mainly 843 rehabilitative agents (copper humate), double-effect spirit, chlorophyll (dtmz), dysentery (polysulfide suspension), metalaxyl manganese zinc (retroviral, manganese zinc, leidomere? Manganese zinc), ethyl phosphine aluminum manganese zinc, copper formate (retrogen copper), nail cream aluminum copper, mixed amino acid copper zinc manganese magnesium, Fodor.
The above is the article on the fungicide recommended for vegetable diseases . I hope I can help you.
