Which soil is good for disinfection of potassium permanganate and dichlorfen?

OK. The methods of disinfection with potassium permanganate soil are:

Before sowing or cuttings to raise seedlings, after the seedbed soil is prepared, if the soil is relatively dry, first wet the topsoil with water, and then dilute it into 400 to 600 times potassium permanganate, spray it evenly on the topsoil with a sprayer, and then cover it with plastic film and seal it for about 1 week, and then remove the film and sow or take cuttings to raise seedlings.

In terms of potted flowers, the soil can be disinfected, and the prepared nutrient soil can be used.

Spray potassium permanganate solution.

Use after sealing with film for a period of time. It can effectively prevent the occurrence of blight, stem blight, cataplexy and root rot.

Four precautions for the use of potassium permanganate:

1. To prepare potassium permanganate aqueous solution, clean water and flowing water must be used, and sewage, stagnant water, and rice washing water must not be used.

etc., otherwise it will reduce its oxidative sterilization function;

2. Potassium permanganate is easy to decompose and fail in hot water and boiling water, so the prepared water must be ordinary cold water. Use with matching, avoid putting it for a long time after matching;

3. Weighing should be accurate. If the concentration is too low, it cannot play the function of oxidative sterilization. If the concentration is too high, it will not only cause waste, but also burn the embryo and inhibit the emergence of seedlings when soaking;

4. Potassium permanganate aqueous solution can only be used alone, and cannot be mixed with any pesticides, fertilizers, etc., otherwise it will seriously affect the effect of potassium permanganate. Staggered with other pesticides or fertilizers.

1. Dilute 600-800 liquid in root irrigation, soak or dress seeds 1000 times.

2. Soil treatment: kilograms per mu, fertilizer sprinkling, hole application or strip application has a better effect.

3. Seedbed disinfection for the seedbed of vegetables, cotton, tobacco, flowers, forestry seedlings, etc., before sowing, treat the seedbed soil with kilograms of oxamypin granules per mu or spray the seedbed soil with 3000-6000 times 96% xamypin (or 1000 times 30% xachlor) carefully, and spray 3 grams of liquid medicine per square meter, which can prevent the occurrence of various diseases such as cataplexy, blight, wilt, root rot, stem rot and so on.

**Fusarium wilt, spring raymycin, potash fertilizer is not the best choice. Because Fusarium wilt is a soil-borne fungal disease, it is necessary to use methalin. Evil mildew comes **, auxiliary spring leimycin compound strengthens the combination of root irrigation and spray, and potassium fertilizer is the most wilt disease.

Carbendazim and magentazim are relatively easy to use for soil disinfection, as for the choice of which one is suitable mainly depends on themselves, carbendazim can be used as a foliar spray

The first method of use, novices use chlorethamine to disinfect when it is paired with soil.

When mixing the soil, 10 liters of soil can be planted after mixing with one gram of dimethyl.

The soil should be used and prepared, and leaving it for a long time will lead to the growth of bacteria, and it needs to be sterilized again when it is used next time.

The second method used, in the process of planting, it is easy to have rotten roots in thousands of seasons.

It can be applied every three months with dimethyl to kill harmful bacteria in the soil. Sometimes the rotten roots of thousands of seasons are more serious, so you need to clean up the rotten part after depotting the flowers, and then soak them with 1000 times of Evilmold for 10 minutes, and then replant them.

<> disinfection of the soil can be done using carbendazim or dichlorfen. Carbendazim: generally used as foliar spray, seed treatment, soil treatment, after use, it can control wheat smut, rice sheath blight, cotton blight, peanut stem rot, sweet potato black spot, tomato early blight and other diseases.

Oxazalin: It is a new generation of new fungicide, which can also be used as a soil disinfectant, and can prevent and control diseases such as sclerotinia sclerotinia in rice, scab in wheat, and gray mold in cucumber.

1. Dilute 600-800 liquid for root irrigation, soak or dress seeds 1000 times.

2. Soil treatment: which kilogram per mu, fertilizer sprinkling, hole application or strip application has a better effect.

3. Seedbed disinfection For the seedbeds of vegetables, cotton, tobacco, flowers, forestry seedlings, etc., before sowing, treat the seedbed soil with kilograms of oxamine granules per mu or spray the seedbed soil carefully with 3000-6000 times 96% xamypin (or 1000 times 30% xachlorin), spraying 3 grams of liquid medicine per square meter, which can prevent the occurrence of various diseases such as cataplexy, blight, wilt, root rot, stem rot and so on.

<> spray with 96% dimethyl (3000-6000 times the solution), spray it evenly on the soil when spraying the solution, and spray it once after 1 week of orange tung dan. Other methods of use: 70% mildin wettable powder can be used for root irrigation for the prevention and control of beet blight, 15% milfylin water agent can be sprayed for the prevention and control of cucumber blight, and 30% mildelin water agent can be sprayed on the seedbed for the prevention and control of watermelon wilt.

1. How to use the soil disinfection of Oxamyco

Before sowing, spray with 96% oxamine (3000-6000 times the solution) or 30% Baiheyuan oxafen (1000 times the solution), spray the liquid evenly on the soil (spray 3 grams of liquid per square meter area), and spray it once after an interval of 1 week to prevent diseases such as cataplexy and blight at the seedling stage.

2. Other ways to use

1. Prevention and control of beet blight.

1) For every 100 kg of seeds, mix seeds with 70% oxamine wettable powder (400-700 grams) + 50% Fumei double wettable powder (400-800 grams), and then sow after mixing.

2) At the beginning of the disease, spray or irrigate the roots with 70% chlormycolin wettable powder (3300 times liquid).

2. Prevention and control of watermelon wilt.

Spray the seedbed or irrigate the roots with 30% oxafen water agent (600-800 times the solution).

3. Prevention and control of cucumber blight and blight.

1) Blight: In the early stage of the disease, spray with 15% Chlormycolin aqueous agent (1000 times the solution), and spray 2-3 kg of liquid medicine per square meter area.

2) Fusarium wilt: 200 ml of 15% dimethyl water (1250 times solution) can be watered on each plant at the time of planting.

4. Prevention and control of tobacco blight.

At the beginning of the disease, it can be sprayed with 70% oxazine wettable powder (3000-3300 times liquid).

5. Prevention and control of tea seedling blight.

Before planting, 50-150 grams of 70% dimephylin wettable powder should be mixed with an appropriate amount of water, and then soil application can be carried out; Or mix 250-800 ml of 15% mildew water with an appropriate amount of water, and then spray the liquid on the soil surface.

Oxazalin can quickly combine with metal ions in the soil to kill germs, strong systemic property, can be absorbed by plant roots, move rapidly, and has the effect of strengthening roots and seedlings, high safety, can be mixed with most pesticides, and the toxicity is very low, so what is the amount of oxazomethoxine soil disinfection?

Oxazole, also known as soil fungus, is a colorless crystal, stable in acid and alkali solution, non-corrosive, low toxicity, heterocyclic fungicide with systemic conduction activity, its mechanism of action is to combine with iron and aluminum ions in the soil to inhibit the germination of pathogen spores, so if it is used for soil disinfection, the soil is alkaline, and the pH of the soil needs to be improved to ensure that the drug can fully play its role. Oxazalin can be absorbed by plants in the body, and two glycosides are produced in the plant, which has the effect of improving the physiological activity of the plant, thereby promoting the growth of the plant, increasing the root hair and improving the activity of the root.

Before sowing the plant, use 3000-6000 times 96% Oxazalin or 1000 times 30% Pyroxamine of Baiheyuan, carefully spray the seedbed soil, spray 3 grams of liquid medicine per square meter, and spray once a week at intervals, which can prevent cataplexy and blight at the seedling stage.

1. Dilute 600-800 liquid for root irrigation, soak or dress seeds 1000 times.
