Potassium permanganate can prevent and cure various vegetable diseases

Manganese is one of the medium and trace elements needed for crops. The small amount of potassium permanganate used in crops lacking manganese has the effect of preventing manganese deficiency, but the amount can not be too large, and manganese will be poisoned by more crops. Potassium is one of the three major nutrients needed for crops. A small amount of potassium permanganate does not make much sense for potassium supplementation.

Potassium permanganate is a strong oxidant and has a killing effect on a variety of pathogenic fungi, bacteria and viruses. In animal husbandry, water production, it is often used for disinfection of instruments.

According to reports, potassium permanganate can be used on melon vegetables to control diseases such as rickets, blight, powdery mildew, downy mildew and soft rot.

First, the control of wilt disease: before the sowing of watermelon, 500-800 times of potassium permanganate spray treatment of the soil, or in the watermelon seedling stage and the extension of the vine period with 500-800 times of potassium permanganate solution, each time each plant About 250 ml can be used to control the rate of diseased wilt disease to less than 0.5%. When the watermelon hail in the field begins to occur, it is immediately irrigated with potassium permanganate 500-800 times, which also has a good effect. When the bitter gourd blight begins to occur, the roots of the wilt disease can be controlled to less than 1% by using a potassium permanganate 500 times solution. After the cucumbers are transplanted, the roots are filled with 150-200 ml potassium permanganate 1000 times per plant, once every 7-10 days, and 2-3 times, which can effectively control the wilt disease.

Second, prevention and treatment of rickets and blight: After transplanting the live aubergine, use 800 times of potassium permanganate to irrigate the roots or spray 800-1000 times with potassium permanganate to prevent the disease. Up to 99% or more. Capsicum seeds are sterilized by soaking seeds with potassium permanganate 500 times for 10 minutes. After soaking, 500-600 times of potassium permanganate is used to spray or root the noodles, which can effectively control diseases such as rickets and blight. happened. After the pepper is planted, the roots are irrigated with potassium permanganate 500 times, and the control effect against blight is as high as 99-100%; if blight has already occurred, 400-500 times of potassium permanganate is used when the initial disease is wilting Liquid irrigation roots also have good results.

Third, the prevention and control of Chinese cabbage soft rot and downy mildew: soaked with potassium permanganate 800-1000 times before planting for 1-2 hours, remove the dry and then sown; spray high in the cabbage seedling stage, rosette period Potassium manganate 600-800 times solution 2-3 times, interval 6-7 days, can effectively control the development of the disease.

Fourth, the prevention and treatment of melon powdery mildew: sprayed with 0.2% potassium permanganate solution 2-3 times, once every 5-6 days, the effect is good.

Use potassium permanganate to control the disease of melons and vegetables. Pay attention to the following matters when preparing and using: First, the weighing should be very accurate, prevent the concentration of the solution from being too large or too small, the concentration is too small, the effect is too small, and the concentration is too large to produce medicine for crops. harm. The second is to use a clean water with a pharmaceutical liquid, without dirty water, sewage with a pharmaceutical liquid, or with hot water with a pharmaceutical liquid, so as not to reduce the sterilization effect. The third is that it can be used as long as it is used. Wash the medicine in time after spraying, otherwise it may damage the medicine.
