Can potassium permanganate be used as pesticide?

Can potassium permanganate be used as a pesticide? Please introduce that we all know that potassium permanganate is a strong oxidizing and reducing agent. In medicine, it is a kind of surgical medicine commonly used by people and animals, commonly known as pp powder. Its solution has strong sterilization, disinfection and antiseptic effect. Some experiments have proved that it is very effective to use its solution of different concentrations to control many kinds of diseases such as flower seedling sudden blight downy mildew soft rot Fusarium wilt root rot virus disease and so on. At the same time, it contains two kinds of nutrients, manganese and potassium, which are necessary for plants, which can promote plant growth and can be described as both medicine and fertilizer. According to medical experts, the drug is rich in sources, low in cost, sold in local pharmacies, easy to purchase, safe to people and animals, non-toxic, no residue to crops, no drug harm, and no pollution to the environment. Therefore, potassium permanganate is a rare fungicide for both medicine and fertilizer, non-toxic, no residue, pollution-free vegetables and flowers. Its main aspects in the prevention and control of plant diseases are: first, prevention and control of stunting disease, petunia wilt, a string of red, marigold after emergence, every 7-10 days with 800-1000 times (first dilute and then concentrated) spray. According to the experiment, the control effect of potassium permanganate on seedling quenching disease is as high as 97%, which is significantly better than carbendazim, zinc benzoate, pentachloronitrobenzene, dimethazone and other pesticides. 2. the practice of controlling downy mildew has proved that potassium permanganate has a good effect on the control of plant downy mildew, which is obviously better than pesticides such as chlorothalonil and zinc benzoate. For example, the occurrence of downy mildew can be effectively prevented if Chrysanthemum morifolium is sprayed with 800 × 600 times of potassium permanganate from 2 leaves to 1 heart before flowering, once every 5-7 days and 4 times in succession. If there is a central diseased plant, spray it with potassium permanganate 600 times solution for 3 times, and the interval is 5 days, which has a good control effect on downy mildew. Third, prevention and control of soft rot potassium permanganate can effectively control the soft rot of red, goldfish grass and marigold. For example, after pre-soaking in high-temperature water for 1 hour before sowing, soaking the seeds in 1000-fold solution of potassium permanganate for 2 hours, and spraying with 800-600-fold solution for 3 times in the seedling stage, soft rot and downy mildew can be effectively controlled. Fourth, the effect of potassium permanganate on the prevention and control of plant virus diseases is significantly better than that of virus A, Shiduqing and other pesticides. In the early stage of the disease, the whole plant was sprayed with 600 × 800 times liquid, once every 5 to 7 days, for 3 times in a row. If the same amount of potassium permanganate and double-acting zhuangsu virus K are mixed with 800-1000-fold solution, the prevention and control effect of virus disease is better, which can not only control the spread of virus disease, but also make the plant disease disappear and restore vitality. However, attention should be paid to the control of prick-sucking pests on plants before the prevention and control of virus diseases, so as to prevent the transmission of virus by insects. 5. Sterilization in greenhouse. Potassium permanganate is added to formalin solution to produce formaldehyde vapor, which disinfects the inoculation box and room of edible fungus, which has a good sterilization effect. During fumigation, every cubic meter of space should be filled with 10 ml of formalin in a cup, quickly add 5 grams of potassium permanganate particles, and fumigate in an airtight box and room for 4 hours and 6 hours. In the use of potassium permanganate spray, attention should be paid to the continuous mixing during dispensing, so that all the drug particles are dissolved and used along with it to prevent long-term oxidation failure. In addition, spraying should be carried out around 9: 00 a.m. or after 4: 00 p.m. After spraying for 5 minutes, the pre-leaf seedlings were washed with clean water in time, low concentration in seedling stage and high concentration in adult stage. 6. disinfect sowing soil, mix potassium permanganate into 800-1000-fold solution, spray carefully with sprayer, and cover with plastic film for 7 days. Sowing with this soil can effectively prevent plant seedling blight, stem rot, quenching disease and so on. Potassium permanganate solution can be prepared with well water, river water, tap water, etc., but stagnant water, sewage and hot water are avoided, otherwise its germicidal efficacy will be reduced. Because potassium permanganate reacts with organic matter, manganese dioxide will be formed and lose its germicidal efficacy. Therefore, it can only be used for external use, and can only be used on demand. Click to get more pesticide application techniques
