What medicine is used for cabbage rotting, and what medicine is used for cabbage rotting

Commonly used agents are:

3000-4000 times of agricultural streptomycin sulfate soluble powder, 4000 times of neophytomycin, 350 times of 14% copper ammonia aqueous solution, 700-750 times of 47% Garinone wettable powder. Spray once every 7-10 days, 2-3 times in a row.

7 Calcium chloride and naphthalene acetic acid mixture in appropriate proportions, spray onto the heart lobe every 7-10 days. Spray once at the seedling stage, rosette stage, and ball-forming stage.

3. Cabbage preservative. Add 15 to 20 kg of water per 15 grams, and spray once in the growth period and heart-wrapping stage of cabbage to enhance the disease resistance of cabbage. At the same time, it has a significant preventive effect on soft rot, black rot, downy mildew, virus disease and other diseases of cabbage.

Cabbage root rot is a common disease, and there are many causes of this disease, including root rot caused by physiological diseases, and pathological root rot caused by soft rot. This has a lot to do with excessive rainfall, high soil moisture, and high and low temperatures.

Cabbage belongs to the cold vegetables, the suitable temperature for growth is 10 22, not heat-resistant, when the temperature exceeds 32, the photosynthesis is very weak and the respiration is enhanced, and the growth is very weak.

Chinese cabbage is a moisture-loving vegetable, and moist soil conditions are required throughout the growing season, especially Chinese cabbage can not lack water in the rosette stage and the core stage. Cabbage is also not resistant to waterlogging, and long-term water staining will also cause the roots to die. Because in the high temperature season, if there is continuous rain, the soil is full of moisture, lack of oxygen, and the roots of cabbage have anaerobic respiration, which will lead to the death of root cells.

Rot is a bacterial disease that spreads with the direction of the water flow. excessive soil moisture in vegetable fields; Excessive planting density, poor ventilation and light transmission; pest spread; The temperature difference between day and night is too large, and the light is not enough on cloudy days, and the plant growth is poor; Partial application of nitrogen fertilizer, insufficient phosphorus and potassium fertilizer will promote the occurrence of diseases.

Prevention and control methods: 1. Once the diseased plant is found, immediately remove and bury it to prevent it from spreading pathogens and infecting other plants;

2. Improve the small environment of vegetable fields, such as reasonable dense planting, reasonable irrigation, timely prevention and control of pests and diseases, balanced fertilization, etc.;

3. Irrigate or spray the roots with 1000 times of Tiandano Kill Liquid, 500 times of Kangdi Leide Liquid, 2000-3000 times of Special Sterilization King and other liquid for root irrigation or spraying control, spray once every 3-5 days, and spray 2-3 times in a row.

1. You can choose 2000 times of 72% agricultural streptomycin sulfate soluble powder or 2000 times of neophytomycin, spray 1 time every 7 days, and spray 2 3 times in a row. When spraying, potassium dihydrogen phosphate can be mixed with 200 grams per mu. Soft rot bacteria like alkaline environment, vinegar can be added 500 800 ml per mu during the prevention and control, which is conducive to improving the disease resistance of plants.

2. You can add 50 kg of water to 100 150 grams per mu of vegetable Fengling, spray 1 2 times or drip into the vegetable field with 751 liters per mu of agricultural resistance.

3. Cabbage preservative can be used to coat 15 20 kg of water per 15 grams, and spray once in the cabbage growth period and the hearting period, which can enhance its ability to resist cold, drought and disease, and at the same time has a significant preventive effect on soft rot, black rot, downy mildew, virus disease and other diseases of cabbage.

4. Spray with 1500 times of liquid foliar bend, spray once every 8 10 days, and spray 2 times in a row.

5. In order to reduce the incidence of soft rot, when planting Dabaiqi vegetables in the coming year, the majority of vegetable farmers should also pay attention to the selection of disease-resistant varieties. crop rotation and stubble, appropriate late sowing; Half-ridge planting reduces the number of field operations and man-made trauma and mechanical damage.

Cabbage suffering from rot disease, can be sprayed 75% chlorothalonil wettable powder 600 times liquid to prevent and control at the beginning of the disease, if the disease is serious, you need to use 69% Anker manganese zinc wettable powder 900 times liquid liquid irrigation roots, in order to prevent cabbage rot disease, to choose a strong resistant variety for planting, and wait until the crop is harvested, to deep plough the soil.

Cabbage suffering from rot disease, can be sprayed 75% chlorothalonil wettable powder 600 times liquid to prevent and control at the beginning of the disease, if the disease is serious, you need to use 69% Anker manganese zinc wettable powder 900 times liquid liquid irrigation roots, each plant to irrigate 75-100 ml of medicine.

After the cabbage is infected with rot disease, it begins to develop disease from the heart stage, the bottom of the plant will produce translucent infiltration spots, and then the lesions gradually expand into gray-white, when the disease is severe, the leaves wilt and fall off, the leaf balls will be exposed, and finally the whole plant dies, rot disease is a bacterial disease, often in the spring when the temperature is low, the humidity is high, after the temperature warms up in July, the Chinese cabbage begins to bulb the stage, at this time the rot disease also enters the high incidence period, after September, the precipitation increases, resulting in the increase of humidity in the field, The rot disease has entered its peak period.

To prevent cabbage from rotting disease, it is necessary to choose varieties with strong disease resistance for planting, and after the crop is harvested, it is necessary to deepen the soil to speed up the decay and decomposition of the diseased residues, and at the same time pay attention to not let the field produce stagnant water, otherwise the excess water needs to be discharged in time.

Hello. Irrigate the roots with chemicals. Before the onset of root rot, spray or irrigate with one of the following agents:

50% carbendazim wettable powder 600 times liquid; 50% thiophanate-methyl wettable powder 500 times liquid; Split 70% methyl tobuzin wettable powder 5o0 times liquid; 75% chlorothalonil wettable powder bridge 6o0 times; Take the drug once every 7-10 days, 3-4 times in a row.

Chinese cabbage rot disease can be sprayed once every 7 10 10 days, 2 3 times in a row, 700 750 times in 47% Garinon wettable powder or 350 times in 14% copper ammonia aqueous solution, every 7 10 days, and 2 3 times in a row. Chinese cabbage rot disease is a common disease of Chinese cabbage, and the causes of Chinese cabbage infection include excessive rain and uncomfortable temperature.

Prevention and control of Chinese cabbage rot disease

After the Chinese cabbage produces rot disease, the infected plants need to be cleaned up first, and then the corresponding drugs are sprayed, and the soil around the infected plants needs to be disinfected with quicklime.

When planting Chinese cabbage, you need to choose good disease resistance and withered seeds, during the growth of Chinese cabbage, you need to properly replenish water, but the amount of watering should not be too much, keep the soil slightly moist, the amount of watering needs to be controlled in the rainy season, and you also need to discharge the water in the soil in time.

Chinese cabbage likes a cold growth environment, the suitable growth temperature is 10 22, when the outside temperature reaches 32, the growth of the plant will be affected, need to do a good job of cooling measures, and increase ventilation.
