1. Use disease-free ginger and ginger to disinfect. Leave disease-free seeds or use disease-free ginger seeds. Before sowing, cut the ginger soaked with 50% carbendazim WP 800 times for 6 hours, or soak with 2000 times liquid for 24 hours. . 2. Ginger choice and disinfection. The bacteria can survive in the soil for more than 2 years. The crop rotation should be strictly implemented and the cornices should be properly arranged. The land that has not been grown with ginger for 3 years is the best. Before sowing, combine 667 square meters (1 mu) of ploughshare with 5~10 kg of quick lime into the field and make the lime fully contact with the soil by turning the hoe; or use the soil bactericide from Beinonglv to directly spray the soil on the soil. . This can play a role in sterilization. 3. Standardize cultivation management. The first is to use mulching film to cover planting and plant densely to improve the disease resistance of plants. The second is the application of net fertilizer, increased phosphorus and potassium fertilizers and trace element fertilizers to enhance plant resistance to disease. The third is reasonable water management. When the water is poured, the water is poured and the soil is kept wet. After the rainstorm, the water is drained and the well water is used to flush the water. The fourth is to timely cultivating weeds and soil and prevent pests. 4. Chemical control. First, the diseased plant was found out in time, and quicklime was used to disinfect the diseased hole and surrounding soil. The second is to strengthen the prevention and treatment of the disease before the onset, can be used 20% Ye Kuanging 1300 times or 50% Johnson Sun 1000 times spraying the lower part of the plant or watering roots, every 7 days, for 3 to 4 times. The third is to continue drug control in the middle period of onset, with the use of agricultural streptomycin 5000 times or more than 50% of Fengnong wettable powder 600 times liquid spray or rooting, every 8 to 10 days, 2 or 3 times in a row.
