1. Agricultural prevention and control
Crop rotation with grasses, melons, onions, garlic or cruciferous crops for more than 4 years. Choose disease-resistant varieties, high ridges or high furrows, and use Tolubam as rootstock for grafting cultivation. Drip irrigation or micro-irrigation facilities are used for watering, flood irrigation is avoided, watering is properly controlled during the onset period, formula fertilization, and phosphorus and potassium fertilizers are added.
2. Seed disinfection
It can be soaked in warm water at 52 °C, or soaked with 30% new phytomycin for 30min, washed and sown by germination. Or soak seeds with 300 times of 010 million live spores/g of Bacillus polymyxoides fine granules, or pour 0.3g/㎡ on the seedbed.
3. Soil disinfection
Solar heat can be used to disinfect the soil during the summer high temperature season. Or 667 square meters mix 100~150kg of slaked lime with 1000~2000kg of crushed straw or wheat straw, sprinkle the soil surface, then plough and water enough water and then cover the mulch, close the greenhouse or greenhouse for about 20 days, so that the soil temperature continues at about 50 °C, killing the germs in the soil.
4. Control underground pests
The pathogenic bacteria mainly invade from the wound at the base of the root or stem, so it is necessary to do a good job in the prevention and control of underground pests such as grubs and mole crickets, so as to avoid underground pests from injuring the roots and reducing the probability of pathogenic bacteria from the root or stem base. Use 500 times of 30% trichlorfon emulsifiable concentrate, 1000 times of 50% phoxanthion emulsifiable concentrate, or 1000 times of 80% trichlorfon soluble powder.
5. Biological control
After colonization or at the beginning of the disease, 1 billion live spores/g Bacillus subtilis 700 times liquid, 100 billion live spores/g Bacillus subtilis wettable powder 1500~2000 times, 800 million live spores/g Bacillus cereus wettable powder 100~200 times liquid, 80% allicin emulsifiable concentrate 1000~1100 times liquid or 77% copper hydroxide wettable particle powder 500 times liquid can be sprayed or irrigated, and each plant irrigation solution is 250~500mL.
6. Chemical control
After planting or at the beginning of the disease, you can choose 200 times of 5% bacterial poison water agent, or 47% Chunlei Wang copper 600 times + 3% Zhongshengmycin 800 times liquid, 14% copper ammonia water 300 times solution, 50% copper succinate wettable powder 500 times, 20% thiazole copper suspension 600 times liquid, 25% thiazole wettable powder 500 times liquid, 20% sodium dichloroisocyanurate soluble powder 300 times liquid, 42% trichloroisocyanurate soluble powder 3000 times liquid, 50% Chlorbromoisocyanurate soluble powder 1500 times, 3% chrynucleomycin aqueous solution 300 times, 20% thiasen copper suspension 300 times, 20% thiazole zinc suspension 400 times, 20% thiophanene wettable powder 600 times liquid spray or root irrigation, 250~500mL of each plant irrigation solution, irrigation once every 7 days, 3~4 times in a row, pay attention to the agent to be used alternately. When it is found late, the diseased plant should be uprooted in time to prevent the spread of the disease, and a little lime should be sprinkled on the diseased hole to prevent the spread of the disease.
