Potassium permanganate is a strong oxidant, strong sterilization, disinfection for control vegetable seedling damping-off, blight, downy mildew, soft rot, wilt, root rot, virus good disease and other effects. Together, rich in manganese, potassium, there are bound to crop yield.
Seed disinfection with warm water cabbage, broccoli and other cruciferous vegetables seeds 1 hour, then potassium permanganate 1000 times soaking 8 to 10 hours, to avoid cruciferous vegetables, soft rot and other diseases. Eggplant seeds by 1000 times the potassium permanganate soaked tomatoes, peppers, eggplant and other 15 to 20 minutes, can prevent viral diseases, early blight, anthracnose, leaf spot diseases. Vegetable seeds after soaking with potassium permanganate solution using clean water to flush repeat, germination or cultivation dried farming.
Seedling disease prevention potassium permanganate for downy mildew control effect than chlorothalonil, zineb and other agents. Avoid cabbage downy mildew in seedling and rosette stage with potassium permanganate spray 800 times, every 5 to 7 days spray once, spraying three times in succession. Avoid cucumber downy mildew, at 2 leaf stage to the front melon with potassium permanganate 800 to 1000 times spray, spray every 5 to 7 days once, spraying four times in succession. When vegetables downy mildew attack, a series of potassium permanganate spray 600 to 800 times 3 times, good control effect. Prevention eggplant damping-off, blight, etc., with potassium permanganate 800 to 1000 times spray, spray every 5 to 7 days once, spraying four times in succession. In the early onset eggplant with pepper spray potassium permanganate 800 to 1000 times, zucchini and other vegetables and melons with potassium permanganate from 1000 to 1200 times spray, spray every 5-7 days time, a series of prevention and control 3 to 4 times, you can manipulate the viral disease. Avoid cowpea Fusarium wilt, root rot, available potassium permanganate from 800 to 1000 times spray 5-7 leaf stage start every 5 to 7 days spray once, successive spraying 2 or 3 times. Powdery mildew prevention melons and vegetables, with potassium permanganate 500-600 times spray, spray every 5 to 7 days once successive spraying three to four times.
Adult stage IRRIGATING avoid Fusarium, can after pepper fruit with potassium permanganate IRRIGATING 500 times, every 7 to 10 days filling time, and even irrigation 3 to 4 times. Pepper root rot attack, with potassium permanganate IRRIGATING 600 times, every 5 to 7 days filling time, filling even four times better control effect. Prevention cowpea wilt, root rot, from 5-7 leaf stage start watering potassium permanganate 800 to 1000 times 3 to 4 times. Cowpea Fusarium wilt, root rot diseased plants, with potassium permanganate IRRIGATING 800 times, every 5 to 7 days filling time, even four times irrigation, also has a significant control effect. Prevention melons Wilt, Fusarium, eggplant damping-off disease, potassium permanganate IRRIGATING 800 times, each time filling liquid per plant 200 to 250 ml. Vegetable seedling watering solution of potassium permanganate amount can not be too large to bed soil moist for the degree, washed with water after application foliage, avoid injury by Barley.
