If the climate is dry, water should be watered in time to preserve soil moisture. After slow leaf application, foliar fertilizer and plant growth regulators can be sprayed to increase photosynthetic efficiency, synthesize photosynthate, transport nutrients to the root system, improve nutrient conversion rate and soil loosening capacity, and promote expansion according to.

3. Chemical control

After discovering the diseased plant, it should be pulled out and burned in the field in time, and then sprinkled with a layer of lime powder in the disease hole to eliminate the bacteria in order to avoid spread, and then sprayed with methyl topiramate plus an appropriate amount of new high-fat membrane to prevent the disease from spreading.
