The Role And Color Of Potassium Permanganate Solution

Do you know about the role and color of potassium permanganate solution? Potassium permanganate is a strong oxidizing reducer, and its solution has the effect of sterilization and disinfection, which is widely used in life, for example, some people will use it to soak their feet, or people who have hemorrhoids will also use potassium permanganate sitz bath.

Scientists are studying the role and color of potassium permanganate solution. However, few people know that in fact, potassium permanganate can also be used to prevent and control crop pests and diseases. In the 1980s, some regions used to soak rice seeds with potassium permanganate, which was very effective in preventing rice blast and blight. Later on, the popularity of chemical fertilizers and pesticides has gradually reduced the agricultural use of potassium permanganate. Some scientific progress has been made in the role and color of potassium permanganate solution.

In recent years, farmers have begun to use potassium permanganate again to prevent pests and diseases, with more desirable preventive effects.

First of all, potassium permanganate can prevent Sudden Falling Disease (SBD) and Verticillium wilt disease in eggplants and fruits. It is more likely to occur on crops such as eggplant, peppers and tomatoes.

Take tomato as an example, tomato seeds can be soaked in warm water for 3-4 hours before sowing, and then put into potassium permanganate 500 times for 15 minutes, rinsed with water, placed in the shade to dry naturally and then sown, and finally sprayed with 1000-800 times of solution (dilute then concentrated) 3 times every 7-10 days after seedling emergence. The incidence of the crop can be controlled within 2%.

Some scientific experiments on the role and color of potassium permanganate solution are being conducted now. In addition, potassium permanganate solution can also prevent melon powdery mildew and melon blight, the prevention and control effect is also very good. For example, watermelon blight, which is a devastating soil-borne fungal disease. Many melon people call him the "cancer" of watermelon. The symptoms of watermelon blight are that the young watermelon buds are affected and may rot and die in the soil and cannot emerge from the seedlings. After the seedlings will also develop, the leaves appear wilted, stem skin longitudinal cracks, often accompanied by resin overflow, air-drying will appear red-black. When the weather is wet, red mold is commonly seen on the diseased parts.

According to the test, in the plots with wilt, respectively in the watermelon seeding, seedling and vine three stages, with potassium permanganate solution spraying and root irrigation, generally can control the incidence of watermelon wilt to less than 0.5%. When the plant wilts at the beginning of the growth period, you can also use potassium permanganate 500 times to irrigate the roots, the cure rate can reach 80% to 90%.

While preventing pests and diseases, potassium permanganate can also supplement vegetables with two nutrients needed for manganese and potassium, effectively improving vegetable yields with the dual role of fertilizer and pesticide. In addition to these vegetable crops, potassium permanganate can also help eliminate pests in flowers that are normally kept.

In addition, it can also be used as a disinfectant for potting soil. Generally speaking, the potassium permanganate solution for soil disinfection is 0.05%-0.1% (light purple in color), then poured into the potting soil, covered with a film, smothered for 2-3 days and then potted. This will basically ensure that the germs and pest eggs in the soil are completely eliminated.

Another use is to disinfect the seeds, and the concentration is usually around 1%. The method of disinfection is to soak the seeds in a solution, the exact time of soaking is determined by the variety of seeds. After soaking for 2 to 3 hours, the seeds are washed and dried with water and then sown, which eliminates the germs carried by the seeds and promotes rapid germination and neat growth of crops.

Potassium permanganate is not only used for vegetable cultivation to prevent pests. Many fish farmers also use potassium permanganate to sterilize their fish ponds. When using potassium permanganate to disinfect fish tanks, there are generally two types of situations: fishing and not fishing. If you fish, the concentration of the drug can be controlled at about 3%-5%, soak for 30 minutes and then pour it out. If you do not fish, the concentration should be kept at 0.5ppm, otherwise it will be detrimental to the fish.

One of the problems that many big fish farmers are troubled by is the fear of fish disease, such as some fish will rot because of fungal infection. If the rotten tail is not serious, usually soaked in salt water for 1 to 2 days will be good. In serious cases, you need to use medication, potassium permanganate is a powerful drug to treat this fungal infection, we can use diluted potassium permanganate solution to soak sick fish, a day at most soak once, each time soak 15-20 minutes or so. So you can not soak for a long time, mainly because it has a certain corrosive, so you need to control the amount, once the excess will be a threat to the health of the fish.
