Summary of common uses and usage of potassium permanganate

Summary of the common uses and usage of potassium permanganate The editor of Guangzhou Helong Trading Co., Ltd. summarizes the uses of potassium permanganate based on years of experience in using potassium permanganate. If there are any irregularities, please criticize and correct them. Welcome to our website to participate in the discussion.

Potassium permanganate use one: disinfection

Usage and dosage: for external use. For wounds and cavities, use 0.1% aqueous solution; gastric lavage 0.1% -0.2% aqueous solution; mouthwash 0.5% solution; wash vagina or sitting bath 0.125% solution, 0.1% solution for cleaning ulcers and abscess, 0.1% solution Disinfect the fruit and soak for 5 minutes. Anti-inflammatory: Potassium permanganate is a strong oxidizing agent. It releases new ecological oxygen in the presence of organic matter and has the effect of killing bacteria. Its sterilizing power is extremely strong, and a solution with a concentration of 1: 2000-1: 5000 is commonly used in clinical to wash skin wounds, ulcers, thrush, and abscesses. The solution gargle is used to remove bad breath and mouth disinfection. It should be noted that the concentration of the solution must be accurately grasped. Excessive concentration will cause partial corrosion and decay. When equipping the solution, consider the moment when the potassium permanganate releases oxygen slowly. The immersion moment must reach 5 minutes to kill the bacteria. Use cold boiled water to make the solution, and hot water will be invalid. Potassium permanganate is widely used in the field of disinfection. Specific to the concentration and usage of each part, there are many differences. The editor will introduce it separately in our company (Guangzhou Helong Trading).


Potassium permanganate use two: gastric lavage

When mistakenly taking plant poisoning in the wild, we should quickly gastric lavage to reduce the absorption of toxic substances. The simple method is to lavage the stomach with potassium permanganate solution with a concentration of 1: 1000-1: 4000. The simple way to check this concentration is to look directly at the solution as lilac or light red. If the solution is purple or dark purple, its concentration has reached 1: 100-1: 200. This extremely high concentration of potassium permanganate The liquid can cause ulceration of the gastric mucosa, and it must not be used for gastric lavage. Mistake of extremely high concentrations of potassium permanganate solution can cause poisoning, so pay attention to safe use

Potassium permanganate use three: clean water

Potassium permanganate is a customary additive for water purification in waterworks. When taking water in the wild, add three or four tablets of potassium permanganate in 1 liter of water and drink it in 30 minutes.

Potassium permanganate use four: vegetable control

Potassium permanganate can control vegetable diseases

Manganese is one of the medium and trace elements required by crops. When crops are short of manganese, a few applications of potassium permanganate can avoid manganese deficiency. Potassium is one of the three major nutrients required by crops. A few applications of potassium permanganate have little meaning in supplementing potassium. Potassium permanganate is a strong oxidant, and it can kill a variety of pathogenic fungi, bacteria, viruses, etc. It is often used to disinfect equipment in animal husbandry and aquatic products.

According to reports, potassium permanganate can be used to prevent and cure diseases such as cataplexy disease, powdery mildew, Fusarium wilt, soft rot and other diseases on vegetables.

1. Control Fusarium wilt

Before watermelon cultivation, treat soil with 500-800 times of potassium permanganate spray, or irrigate roots with 500-800 times of potassium permanganate during watermelon seedlings and vines, each time about 250 ml per plant. Control the incidence rate of Fusarium wilt under 0.5%. When the watermelon wilt in the field begins to attack, it is also effective to irrigate the roots with 500-800 times of potassium permanganate solution. When the bitter melon wilt began to develop, irrigating the roots with 500 times potassium permanganate solution could control the death rate of fusarium wilt under 1%. After transplanting live cucumbers, each plant is irrigated with 150-200 ml of potassium permanganate 1000 times solution, once every 7-10 days, and 2-3 times, which can effectively prevent fusarium wilt.

2. Prevention and treatment of cataplexy disease and drought blight

After transplanting the eggplants to live trees, rooting with 800 times potassium permanganate solution or spraying seedlings with 800-1000 times potassium permanganate solution can prevent over 99% of cataplexy diseases. Pepper seeds are soaked and disinfected with potassium permanganate 500 times solution for 10 minutes, and then sprayed or irrigated on the border surface with 500-600 times potassium permanganate solution after seedlings can be used to effectively control diseases such as damping-off disease and stand-off disease Seizures. After the pepper is planted, the roots are irrigated with 500 times potassium permanganate solution, and the control effect against fusarium wilt is as high as 99-100%; if the fusarium wilt has already occurred, 400-500 times potassium permanganate is used when the diseased plants first wilting Liquid root irrigation also has a better effect.

3. Controlling Chinese cabbage soft rot and downy mildew

Before cultivating, soak the seeds with potassium permanganate 800-1000 times solution for 1-2 hours, remove the shade and dry before cultivating; spray 600-800 times solution of potassium permanganate 2-3 times during the seedling stage and rosette stage of Chinese cabbage Once every 6-7 days, it can effectively control the disease.

4. Prevention and treatment of powdery mildew of melon and vegetable

Spray 2-3 times with 0.2% potassium permanganate solution, once every 5-6 days, the effect is outstanding. The use of potassium permanganate to control melon and vegetable diseases should pay attention to the following items when manufacturing and using: First, the weighing should be very accurate, to avoid the solution concentration is too large or too small, the concentration is too small, the effect is not good, if the concentration is too large, it will attack the crop harm. The second is to use clean water to make liquid medicine, no dirty water or sewage to make liquid medicine, nor hot water to make liquid medicine, to avoid reducing the sterilization effect. The third is to accompany the use, not for a long time. Clean the medicine equipment in time after spraying, otherwise the medicine equipment may be damaged.
