Bacterial wilt is an important disease of tomato. Generally, it does not show symptoms at the seedling stage, and it begins to occur when flowering and fruit setting. Tomato bacterial wilt pathogens are prone to occur in slightly acidic soils, high temperature and humidity, continuous cropping, low-lying terrain, poor drainage, potassium deficiency, and root damage. Practice has proved that better prevention and control effects can be achieved by adopting comprehensive prevention and treatment measures such as optimizing varieties, rotating crops, strengthening cultivation and management, removing pathogens, and chemical control. When sporadic diseased plants are found in the field, burnouts should be immediately removed, and lime powder or ash should be applied to the diseased cavities, or 2% formalin or 20% lime water should be instilled into the diseased cavities. After harvesting, the diseased plants were promptly removed and burned. In the selection of pesticides, 72% of the agricultural streptomycin sulfate soluble powder 4000 times solution, or 25% solution ammonia copper water solution 500 times, or 77% can be used to kill wettable powder 4,000 times. Liquid, or 50% citrate copper (DT) wettable powder 400 times Irrigation roots, each irrigation 0.3 to 0.5 liters, 7 to 10 days irrigation once, alternately using different agents, even irrigation 3 to 4 times, control The effect is good.
