Potassium permanganate is a strong redox agent, and its solution has strong sterilization, disinfection and antiseptic effects. At the same time, it contains two nutrients such as manganese and potassium, which can be used to promote plant growth. In addition, its low cost, easy to purchase, and safe and non-toxic to humans and animals during use, no residue on the crops, no phytotoxicity, no pollution to the environment, has a peculiar effect in the production of pollution-free vegetables and flowers.
Prevention and treatment of rickets and blight. After the flowering of petunia, a bunch of red, marigold and other flowers, every 7 to 10 days with 800-1000 times of potassium permanganate (first diluted and concentrated) spray, the control effect against sputum is as high as 97%, significantly superior Pesticides, dexamethasone, pentachloronitrobenzene, diclosan and other pesticides.
Control downy mildew. The cineraria flower is 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, spray with potassium permanganate 600 times for 3 times at intervals of 5 days, the control effect is very good.
Control soft rot. Before pre-soaking for high temperature water for 1 hour before sowing, remove the potassium permanganate 1000 times solution for 2 hours, and spray 800 to 600 times at the seedling stage for 3 to 4 times to effectively control a string of red and goldfish. Grass, marigold soft rot, and can cure downy mildew.
Prevention of viral diseases. In the early stage of viral disease, the whole plant is sprayed with 600-800 times potassium permanganate solution, once every 5 to 7 days, and even sprayed 3 to 4 times, not only can control the spread of viral diseases, but also make the disease of the plants disappear and Rejuvenate. If the potassium permanganate and the double-acting auxin virus K are mixed in the same amount of 800-1000 times solution, the effect of preventing and treating viral diseases is better, but it should be noted that before and after the prevention of viral diseases, the sucking pests on the plants should be prevented. In order to prevent insects from transmitting poison.
The booth is sterilized. The formaldehyde vapor generated by adding formalin solution to potassium permanganate is used to disinfect the inoculation box and chamber of the edible fungus, and has a good sterilization effect. When fumigation, 10 ml of formalin is placed in the cup per cubic meter of space, 5 g of potassium permanganate particles are quickly added, and the cells are fumigation in a closed box and room for 4 to 6 hours. When using potassium permanganate spray, it should be noted that the drug is continuously stirred evenly to dissolve the drug particles, and it can be used as needed to prevent long-term oxidation failure. In addition, the spray should be selected at around 9 am or after 4 pm. 7 pre-leaf seedlings were sprayed with water for 5 minutes and then rinsed with water; low concentration in seedling stage and high concentration in adult stage.
Dissolve the soil with potassium permanganate into 800-1000 times solution, spray it with a sprayer, spray it with plastic film for 7 days, then seeding can effectively prevent plant blight, stem rot, tripping Sick and so on.
The preparation of potassium permanganate solution can be used for well water, river water, tap water, etc., but avoid using dead water, sewage, hot water, etc., otherwise it will reduce its bactericidal effect, due to the reduction reaction of potassium permanganate and organic matter, it will produce dioxide. Manganese loses germicidal efficacy. Therefore, it can only be used externally, and it can only be used with it.
