What are the tips for potassium permanganate to plant pest?

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.

Potassium permanganate is a strong redox agent, which is a common surgical drug for humans and animals. Its solution has strong sterilization, disinfection and antiseptic effects. Experiments have proved that the solution with different concentrations can control various diseases such as cataplexy and blight, frost nahu mildew, soft rot, wilt, root rot, virus disease and other diseases at the seedling stage, and the effect is remarkable.

At the same time, it contains two essential nutrients, manganese and potassium, which can promote plant growth, and can be described as a dual use of medicine and fertilizer. According to medical experts, the drug is rich in sources, low cost, sold in pharmacies all over the world, easy to purchase, and safe for humans and animals when used, non-toxic, no residue on crops, no pesticide harm, no pollution to the environment. Therefore, potassium permanganate is a rare fungicide for vegetables and flowers that is both medicinal and fertilizer, non-toxic, non-residue and pollution-free.

As follows:

1. The chemical equation of the reaction between potassium permanganate and oxalic acid:

2kmno4+5h2c2o4+3h2so4=2mnso4+k2so4+10co2↑＋8h20。

2. The ion equation for the reaction of potassium permanganate and oxalic acid: 2mNO4- +5H2C2O4 +6H + 2MN2+ +10CO2 8H2O.

Precautions for the use of potassium permanganate.

With a concentration of 1/10,000 potassium permanganate solution can be used as a drinking water disinfection for racing pigeons, which can sterilize and prevent dysentery bacillus and coccidiosis infectious diseases of pigeons, so as to achieve the purpose of drinking water disinfection.

Increase the trace element "manganese" to prevent the joints of the pigeon from swelling and deforming. It should be noted that the "potassium permanganate" drinking water for the pigeon is best dissolved in 60 70 warm water, and the water temperature is too high to reduce and invalidate the potassium permanganate, affecting the effect.

When using, it should be used now, and it should not be stored for a long time.
