First, prevention and treatment of rickets, blight pepper, eggplant, tomato before sowing with warm water to soak the seeds for 3 - 4 hours, then add potassium permanganate 500 times in the soak for 15 minutes, rinse with water Sowing after drying in the shade; and after 3 to 10 days after emergence, using 1000-800 times liquid (first diluted and concentrated) spray to prevent and control 3 times, the control effect on the disease of the solanaceous seedlings is as high as 97%, and the effect is remarkable. Pesticides, dexamethasone, pentachloronitrobenzene, diclosan and other pesticides.
Second, the prevention and treatment of downy mildew cucumber in the emergence of 2 leaves 1 heart to the knot before the use of potassium permanganate 800 - 600 times liquid spray, 5 - 7 days once, even spray 4 times, can effectively prevent downy mildew Occurred, and can increase production by 10% - 15%. 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, the prevention and treatment of soft rot potassium permanganate can effectively control the soft rot of cruciferous vegetables, such as cabbage high temperature water pre-dip before planting for 1 hour, remove and then immersed in potassium permanganate 1000 times solution for 2 hours, And in the seedling period to the rosette period with 800-600 times liquid spray 3 - 4 owed, can effectively prevent soft rot, and can also cure cabbage downy mildew.
Fourth, the prevention and control of blight, root rot watermelon can be soaked with 1000 times potassium permanganate solution for 8-10 hours before sowing, and then 1500 times for liquid sputum when planting, and then use 600 after slowing the seedling. - 1000 times of liquid pouring and spraying four times, not only can prevent the occurrence of blight, but also increase production by about 15%. If you are in the field of disease, you should use 800-1000 times of liquid in the early stage of the disease to irrigate the roots of the whole field. Each plant is 1500ml, 5-7 days, and 3 times, can achieve significant control effect. Another example is the prevention and control of pepper root rot, which can be poured with potassium permanganate 500 times after the fruit is placed in the door, 7-10 days, for 3 to 4 times, to prevent the occurrence of pepper root rot. Even if the root rot of the pepper occurs, the root is irrigated with 500 times of liquid immediately after the onset of the disease, once every 5-7 days, and 4 times of continuous irrigation, the control effect can reach more than 90%. For example, prevention and control of cowpea wilt and root rot, from the 5-7 seedling stage of cowpea, it can be effectively prevented by the high-acid potassium 800-1000 times solution for 3 to 4 times; Even if the disease occurs, it is drenched with 600 times of liquid, once every 5-7 days, 4 times in a row, and the control effect is more than 90%.
Fifth, the prevention and treatment of viral diseases in the early stage of the disease, peppers and other solanaceous fruits with 600-800 times liquid, zucchini and other melons and fruits with 600-800 times liquid, zucchini and other melons with 1000-1200 times liquid for the whole plant Spray, 5 - 7 days, even spray 3 - 4 times. If you use 800-1000 times solution of potassium permanganate and double-effect auxin virus K, the effect of preventing and treating viral diseases is better.
