Treatment of eggplant bacterial wilt

Eggplant is a common vegetable in daily life, which is planted in almost every household, and during the period of planting eggplant, there will be withered and yellow leaves. What are the treatments for eggplant bacterial wilt?

1. Reasonable intercropping

Rotation with Gramineae, melons, onions, garlic or cruciferous crops for more than 4 years. A disease-resistant variety, high ridge or high border, was selected and Tolubam was used as rootstock for grafting. Drip irrigation or micro-irrigation facilities were used to avoid flood irrigation, proper control of watering during the disease period, formula fertilization, and increased application of phosphorus and potassium fertilizer.

2. Seed disinfection

It can be soaked in 52 ℃ warm water or soaked in 30min with 30% neophytomycin, washed and seeded. Or soak the seeds with 10 million live spores / g Bacillus polymyxus in 300x solution, or pour 0.3g/ seeds on the seedling bed.

3. Soil disinfection

Solar energy can be used for soil disinfection in summer high temperature season. Or 667 minced rice straw or wheat straw 1000-150kg mixed well, sprinkled on the soil surface, then ploughed and irrigated enough water and then covered with plastic film, closed greenhouse or greenhouse for about 20 days, so that the soil temperature lasted about 50 ℃, killing germs in the soil.

4. Control underground pests

Pathogens mainly invade from the wounds at the root or stem base, 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 root damage and reduce the probability of pathogens invading from the root or stem base. Choose 30% trichlorfon EC 500x liquid, 50% phoxim EC 1000 times liquid, or 80% trichlorfon soluble powder 1000 times liquid and so on to irrigate or spray.

5. Chemical control

After colonization or the initial stage of the disease, 1 billion live spores / g Bacillus subtilis 700x liquid, 100 billion live spores / g Bacillus subtilis wettable powder 1500-2000 times, 800 million live spores / g Bacillus cereus wettable powder 1500-200x, 80% allicin EC 1000-1100 times or 77% copper hydroxide wettable particulate powder 500x were sprayed or irrigated.
