Before the soil is disinfected and sowed, the soil of the seedbed soil is sprayed with 400 to 600 times of potassium permanganate solution, and then covered with plastic film for about 1 week, and the seedlings can be uncovered or seeded. In the case of potted flowers, a potassium permanganate solution can be sprayed onto the prepared nutrient soil and sealed with a film for a period of time. It can effectively prevent the occurrence of blight, stem blight, stagnation, and root rot.
Seedling disinfection with 0.1% potassium permanganate solution for 2 hours or seedling disinfection can prevent soft rot, downy mildew and rhizome disease.
During the growth period, the seedling stage after flowering and unearthing of flowers is sprayed with 800 to 1000 times potassium permanganate solution, sprayed once every 7 to 10 days for 3 to 4 times, which can prevent petunia, a string of red, and Wanshou. Chrysanthemum and other flowers in the seedling stage collapsed, the effect is better than conventional pesticides. From the seedling stage to the flowering stage, it is sprayed with 60-800 times liquid potassium permanganate, sprayed once every 5 to 7 days, and continuously sprayed 3 to 4 times, which can effectively prevent soft rot and downy mildew. The above concentration of potassium permanganate solution can also be rooted for controlling root rot. In the initial stage of flower virus disease, spray 600-800 times liquid potassium permanganate, spray once every 5 to 7 days, spray 3 to 4 times continuously, or use potassium permanganate and double-effect auxin virus K. Mixing 1000 times of liquid spray has a significant effect on the prevention and treatment of viral diseases.
The use of potassium permanganate in flowers is important because potassium permanganate is a strong oxidant, which is prone to reduction reaction with organic matter and loses its bactericidal effect. Therefore, avoid using stagnant water, sewage or hot water during use, and do it with your use. At the same time, prevent mixing with strong alkaline pesticides.
