Comprehensive Control techniques of Ginger Rot

1. Choose disease-free ginger seeds and seed ginger for disinfection. Leave seeds from disease-free areas or select disease-free ginger, soak the seeds before sowing with 50% carbendazim wettable powder for 6 hours, or soak the seeds with 2000 times of neophytin for 24 hours. two。 Ginger selection and disinfection. The pathogen can survive in the soil for more than 2 years, so the rotation should be strictly carried out and the stubble should be arranged reasonably, and the plot which has not planted ginger for 3 years is the best. Before sowing, combine ploughing and raking with 667 square meters (1 mu) and spread 510 kilograms of quicklime evenly into the field to make the lime fully contact with the soil by turning the rake, or spray the water directly on the soil with the soil fungicide. All these can play the role of sterilization and disinfection. 3. Standardize cultivation management. First, the use of plastic film mulching cultivation, reasonable close planting to improve plant disease resistance. The second is to apply net fertilizer, increase the application of phosphorus and potassium fertilizer and trace element fertilizer to enhance plant disease resistance. Third, reasonable water management, watering small water frequently to maintain soil moisture; timely elimination of stagnant water after heavy rain, and flushing irrigation with well water. Fourth, timely ploughing, weeding and soil cultivation to prevent and control insect pests. 4. Chemical control. First, it is found that the diseased plant is pulled out in time, and the disease hole and the surrounding soil are disinfected with quicklime. Second, to strengthen the chemical control in the early stage of the disease, the middle and lower parts of the plant or roots can be sprayed with 1300 times of 20% Ye Kuning or 1000 times of Dysenamine, once every 7 days for 3 or 4 times in a row. Third, continue to carry out drug control in the middle of the disease, spray or irrigate the roots with 5000 times of agricultural streptomycin or more than 50% of Fengnong wettable powder, once every 8 to 10 days, 2 times in a row.
