The price of rotten roots and dead seedlings 120, and the precautions for the use of rotten roots an

The ** of 120 rotten roots and dead seedlings is 126

The special drugs for dead seedlings and rotten roots include fludioxonil, dichlorfen, and bacterial fungicides.

Fludioxonil

Fludioxonil is a more efficient fungicide to prevent dead roots and seedlings, it is mainly aimed at fungal diseases, such as root rot, sclerotinia disease, stem base rot, blight, etc., its safety is very high, not easy to produce pesticide damage, the seedling use effect is very good, can be used for spraying, washing, seed dressing.

Evil mildew

Tetrafen is also one of the most commonly used pesticides for the prevention and control of dead seedlings and rotten roots of crops, and the main objects of prevention and control are also fungal diseases, such as common crop root rot, blight, cataplexy, wilt, etc., the disease prevention range of Oxafen and fludioxonil is similar, but the systemic sterilization effect of Oxazalin is better, and the disease prevention and effect period is relatively long.

Bacterial fungicides

Dead roots and rotten seedlings caused by bacteria, bacterial fungicides should be selected, such as thiazobacter copper, quinoline copper, chunleimycin, etc., the use of organic copper preparations is safer, antibiotic fungicides fungi, bacteria can be prevented, more efficient! Bacterial diseases are stubborn, try to use them twice in a row, through a combination of root irrigation and spray!

Medication precautions

Diseases that cause dead seedlings and rotten roots should be prevented in advance, soil disinfection can be carried out before planting, or fungicides can be sprayed at the seedling stage for prevention.

If the plant has been diseased, then when the dead seedlings are rotten, remember not to use fungicides alone, it is best to use nutrients, because at this time the root system has been damaged, and to promote the recovery of the plant by supplementing nutrients, fungicides can be used with amino acid water-soluble fertilizers.

Summary. Rotten Roots and Dead Seedlings 120 is the latest replacement product of oxazalin developed by agricultural plant protection experts, which is a durous and efficient pesticide fungicide, soil disinfectant, and also a plant growth regulator. The pharmacodynamic effect is unique, with high efficiency, low toxicity, pollution-free, belongs to the green environmental protection high-tech boutique, oxafen can effectively inhibit the normal growth of pathogenic fungal mycelium or directly kill the bacteria, and can promote plant growth; It also has the ability to promote the growth and development of crop roots, take root and strengthen seedlings, and improve the survival rate of crops.

The permeability of the dimethyl is extremely high, and it can move to the stem in two hours and the whole plant in 20 hours.

When using rotten roots and dead seedlings 120, it is necessary to comply with the rules for the protection of pesticide use. 1.When used for seed dressing, the dosage of pesticides should be strictly controlled, and dried immediately after mixing, and the seeds should not be stuffy to prevent pesticide damage.

2. It is advisable to spray in windless and sunny weather, and there is no need to spray in case of rain 4 hours after spraying 3. If you take it by mistake, drink a lot of warm water to induce vomiting, stupid old wisdom gastric lavage, and carry this label to seek medical attention immediately with a response 4, this product can be mixed with general pesticides, and synergize with each other.

1. Fludioxonil: mainly for the prevention and control of stem base rot, blight, root rot and sclerotinia disease. For prevention, spray 25g L fludioxonil suspension 750-1000 times on the foliar surface of the crop seedling stage, and if the crop has been diseased, use 1000-1500 times of fludioxonil to rinse the roots.

2. Chlormycofen: mainly for the prevention and control of root rot, blight, cataplexy and blight. For prevention, spray 1500 times of 30% Oxamine water agent at the seedling stage, and if the crop has been diseased, spray 1000-1500 times of 30% Methyl Frost Oxazalin water agent or drench root treatment.

1. Special medicine for the treatment of dead seedlings and rotten roots

1. Fludioxonil.

1) Fludioxonil is mainly used to control dead seedlings and root rot caused by fungal diseases such as root rot, sclerotinia sclerotinia disease, stem base rot, and blight.

2) At the seedling stage, spray seedlings with 25g L fludioxonil suspension 750-1000 times to prevent root rot and blight. If the crop has been dead seedlings and rotten roots, use 1000-1500 times of fludioxonil to drench the roots.

2. Evil mildew.

1) Oxazalin is mainly used for the prevention and control of dead seedlings and root rot caused by fungal diseases such as root rot, standing blight, cataplexy, and wilt.

2) If it is prevention, you can sprinkle 30-40kg of Oxazomin granules per mu in advance, or spray 1500 times of 30% Oxazoxin water at the seedling stage. If there is already a situation of dead seedlings and rotten roots, use 1000-1500 times of 30% methyl cream and oxamine aqueous solution for spraying or root spraying.

3. Bacterial fungicides.

1) Bacterial fungicides such as thiomyctoxin, quinoline copper, and chunleimycin are mainly used to prevent and control dead seedlings and root rot caused by bacterial diseases such as bacterial wilt and bacterial soft rot.

2) In the prevention and control of bacterial diseases, try to use the medicine twice in a row by combining root irrigation and spraying.

2. What is the cause of dead seedlings and rotten roots?

Crop seedling and root rot are generally caused by soil-borne diseases, and the causes are as follows:

1. Planting the same crop on the same land for a long time leads to the multiplication of a certain pathogen in the area year after year, accumulating in large quantities, and eventually causing soil-borne diseases.

2. Excessive application of fertilizers, especially nitrogen fertilizers, leads to the rapid growth of Fusarium, Verticillium and Rhizoctonia in the soil, which aggravates soil-borne diseases.

3. Nematodes in the soil invade the root system of crops, causing wounds in the roots of crops, which provides favorable conditions for bacterial infiltration.

4. Overwatering leads to too humid soil environment, which not only affects the respiration of crop roots, but also provides favorable conditions for the reproduction and growth of pathogens.
