Potassium permanganate, also known as gray manganese oxygen, powder, is a purple-black crystal, with a metallic texture, dissolved in water, is an oxidant, because it can release new green ecological oxygen and has antibacterial effect, can be used to prevent and control a variety of crop diseases.
Prevention and control of melon wilt. Melon wilt is a devastating soil-borne bacterial disease. According to the experiment, in the three stages of melon planting, seedlings and vine extension, 500 800 times potassium permanganate solution is used for ridge spraying and root irrigation, and the prevalence of melon wilt can generally be manipulated as follows; When the main stem first encounters wilting during the growth period, irrigate the roots with 500 times the liquid, and the rate can reach 80 to 90%.
Prevention and control of Chaotian pepper blight. In the growth period of Chaotian pepper street, irrigation of roots with potassium permanganate 500 times can prevent the occurrence of wilt; If the blight has already occurred, it is necessary to irrigate the roots with 400 500 times the liquid when the main stem first encounters wilting, and the rate can reach more than 90%.
Prevention and control of cabbage soft rot. In the early stage of the disease, immediately spray 500 800 times potassium permanganate solution, spray once every 7 10 days, spray three times in a row, you can manipulate the injury.
Prevention and control of tomato virus disease. When planting, soak the seeds with potassium permanganate solution for 30 minutes; When the disease first occurs, it is sprayed once with 1000 times potassium permanganate solution, and the actual control effect is excellent.
Prevention and control of rice diseases. Before planting, the potassium permanganate solution was diffused for 24 hours, which could reasonably eliminate the pathogenic bacteria adhered to the rice seeds, and could increase the seedling emergence rate and seedling formation rate. In the early stage of rice blast, sheath blight and white leaf blight, potassium permanganate solution should be sprayed immediately, and the actual control effect can reach 85%.
Control of downy mildew in grapes. In the early stage of red grape disease, the sprayer was carried out with 400 600 times potassium permanganate solution, and the actual effect of prevention and control reached more than 95%, which was better than the actual effect of independent spraying of aluminum acetophosphine.
Prevention and control of potted flower diseases. When downy mildew occurs in potted flowers such as Yueji, potassium permanganate solution sprayer is used to prevent and control it, and the actual effect is excellent.
-
Prevention and control of pepper wilt in the field growth period of pepper, irrigation of roots with potassium permanganate 500 times can prevent the occurrence of wilt. In the early stage of the disease, spray 500-800 times potassium permanganate solution in time, spray once every 7-10 days, and spray three times in a row to control the harm.
-
Seeds can be soaked with potassium permanganate, and in the process of soaking, the concentration must be grasped to achieve the effect of sterilization.
-
When using potassium permanganate, it must be noted that it is generally not used too much, and when potassium permanganate is used, it should not be mixed with some other substances, and it must be diluted before it can be used.
-
As a fertilizer, potassium permanganate crops mainly absorb manganese from crops, which has a great effect on promoting crop growth; As a disinfectant, it can disinfect and sterilize crops and prevent disease damage. When potassium permanganate is used as a poisonicide, the concentration of potassium permanganate solution should be appropriately adjusted according to different diseases and different conditions of crop growth period, and then it can be used. <>
The contents are as follows: prevention and control of cataplexy: after transplanting live eggplant, irrigation of roots with potassium permanganate 800 times or spraying seedlings with potassium permanganate 800 1000 times can effectively prevent and control cataplexy.
If the disease has been diseased, potassium permanganate can be used 400-500 times liquid irrigation for better effect; Control of Fusarium wilt: Fusarium wilt is a devastating crop disease, especially for watermelon cultivation. In order to more effectively control watermelon wilt, the soil can be treated with 500 800 times potassium permanganate solution before watermelon sowing, and then 500 800 times of potassium permanganate can be continuously sprayed at the seedling and vine stage of watermelon. <>
Treatment of soft rot: soft rot is mainly caused by plant diseases, caused by Bacillus eleide bacteria and Rhizopus fungi, to prevent the occurrence of this disease, we must first start from the seeds: put the seeds into potassium permanganate 800-1000 times liquid soaked for 1-2 hours, remove the shade and dry before sowing, and spray with 1000 times the liquid in the seedling stage of the crop, and spray with 1000 times the liquid in the seedling stage of the crop, effectively prevent; Treatment of viral diseases:
Viral disease is a disease caused by plant virus parasites, and its symptoms are mainly manifested in crop leaves, such as: mosaic type, yellowing type, necrotic type, and deformity type. The control method is to spray 600 800 times potassium permanganate solution continuously for one month at the beginning of the disease, but before that, the stinging pests on the crops should be controlled.
to prevent insect poisoning. <
-
There are a lot of tricks. First of all, it can be a viral disease, a number of diseases caused by plant virus parasitism, soft rot, wilt, cataplexy, and other agents need to be added.
-
We can choose to dilute potassium permanganate a little bit and spray it on crops, which can cause a lot of damage to some bacteria and will not cause any problems to plants.
-
According to the pests and diseases of crops or pesticides, choose the appropriate concentration of pesticides, you should pay attention to the time of use, and at the same time, you should avoid rainy days or when the air temperature is relatively high, and you should do a good job of ventilation.
-
Operators operating potassium permanganate must be specially trained, strictly abide by the operating procedures, stay away from fire and heat sources, and strictly prohibit smoking, eating and drinking in the workplace. The operating environment is closed and the ventilation is strengthened. Avoid dust generation.
Avoid contact with reducing agents and active metal powders. When handling, it is necessary to load and unload lightly to prevent damage to the packaging and containers. Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment.
Empty containers may leave harmful substances behind.

Potassium permanganate can be directly watered to prevent and control cataplexy and blight, downy mildew, soft rot, wilt, root rot, virus disease and other diseases at the seedling stage with its solution of different concentrations, and the effect is very significant. At the same time, it contains two kinds of nutrients, manganese and potassium, which are necessary for plants, which can promote plant growth and can be described as a dual use of medicine and fertilizer.
Disinfection, sterilization, insecticide, and so on, which is the same in agriculture and aquaculture, but now agriculture generally has organic pesticides.
