Potassium permanganate is a strong redox agent. It is a kind of surgical medicine commonly used by humans and animals. It is commonly known as pp powder. Its solution has strong sterilization, disinfection and antiseptic effects. Some experiments have proved that the use of different concentrations of solutions to control vegetable seedling stage rickets and blight, downy mildew, soft rot, blight, root rot, viral diseases and Other diseases, the effect is very significant. At the same time, it contains two kinds of nutrients such as manganese and potassium, which can be used for plant growth. It can be said to be used for both medicine and fertilizer. According to medical experts, the drug is rich in source and low in cost. It is sold at pharmacies all over the country and is easy to purchase. It is safe and non-toxic to humans and animals when used. It has no residue, no phytotoxicity to the crops, and no pollution to the environment. Therefore, potassium permanganate is a kind of fungicide with both medicine and fertilizer, non-toxic, no residue, pollution-free vegetables and flowers. It mainly includes in the prevention and treatment of plant diseases:
First, prevention and treatment of rickets, blight. Various kinds of melons, solanaceous fruits, cruciferous vegetables are sprayed 800 to 1000 times (first diluted and then concentrated) every 7 to 10 days after emergence. According to the test, the effect of potassium permanganate on the disease at the seedling stage is as high as 97%, and the effect is significantly better than that of carbendazim, dexamethasone, pentachloronitrobenzene and dikesone.
Second, the prevention of downy mildew. Practice has proved that the use of potassium permanganate to control plant downy mildew has a good effect, significantly better than chlorothalonil, daisen zinc and other pesticides. For example, the cineraria can be sprayed with potassium permanganate 800-600 times before the flowering, and then sprayed 4 times for 5 to 7 days, which can effectively prevent the occurrence of downy mildew. In the case of a central diseased plant, it is sprayed three times with 600 times of potassium permanganate, with an interval of 5 days, which has a good control effect on downy mildew.
Third, prevention and treatment of soft rot. Potassium permanganate can effectively control the soft rot of a string of red, snapdragon and marigold. For example, after pre-soaking for high temperature water for 1 hour before sowing, remove and put in potassium permanganate 1000 times for 2 hours, and spray 800 to 600 times at seedling stage for 3 to 4 times to effectively prevent soft rot. And can cure downy mildew.
