Strictly Prevent and Control the Seven Key Steps of Ginger Rot Ginger rot, also known as ginger soft rot, is a bacterial disease caused by *Pseudomonas* species. It can severely affect ginger crops, leading to significant yield losses and economic damage. As there is currently no effective chemical treatment available for this disease, the focus must be on integrated agricultural practices to prevent and control its spread. To effectively manage ginger rot, it's essential to strictly monitor and control the following seven key steps: 1. Land Selection and Crop Rotation:
The pathogens of ginger rot can survive in the soil for up to six years, making it a major source of infection. Therefore, crop rotation is crucial. Avoid planting ginger in areas previously used for tomatoes, peppers, eggplants, potatoes, or peanuts. It's best to choose elevated, well-drained land and ensure that the previous crops were not related to ginger. A rotation cycle of one year of ginger followed by two years of rice is recommended. 2. Selecting Healthy Seed Ginger:
Only use disease-free, insect-free, plump, and bright ginger seeds. After harvesting, dry the ginger in the sun for two days, then remove any discolored, soft, or water-stained pieces. Choose only those with firm skin and healthy buds for planting. 3. Seed and Soil Disinfection:
Soak the ginger seeds in a 500-fold solution of copper thiophene (Lactococcus) for 3 hours to promote germination and disinfect. Alternatively, use a 1:1:150 Bordeaux mixture for 15–30 minutes. After soaking, treat the wounds with plant ash or a 300-fold solution of T. bronchodendron (Loncobacter) to prevent bacterial entry through cuts. For soil disinfection, spray formaldehyde before sowing and cover with plastic film for 4 days, then aerate for 3 days. Alternatively, apply 20% thiazolybdate (Loncobacter) at 500 times dilution. 4. Field Management:
Use sufficient organic manure and avoid using contaminated materials such as ginger stems, leaves, or soil for compost. Level the field, deepen ditches, and ensure proper drainage to prevent waterlogging. Keep fields isolated from each other, avoid overwatering, and do not allow infected fields to flow into clean ones. Apply phosphorus and potassium fertilizers, along with wood ash, and avoid excessive nitrogen. Regularly inspect the fields and remove diseased plants immediately, destroy them, and spray the area with a 5% bleaching powder solution or fresh lime powder to maintain hygiene. Throughout the growing season, spray 20% Thiobacillus copper (Loncobacter) 3–4 times to prevent bacterial infections. 5. Unified Prevention Measures:
Ensure coordinated efforts in prevention, including mass control, major interventions, and both agricultural and chemical methods. Use uniform timing, consistent products, and standardized techniques. When seedlings emerge, apply 20% Thiobacillus copper (Loncobacter) at 500–750 times dilution, pouring 100–150 ml per hole. From the 3–5 leaf stage, when pests like the ginger borer appear, focus on comprehensive control. Spray 20% Thiobacillus (Loncobacter) at 500 times, repeating 3–4 times with a 7–10 day interval. Copper hydroxide or agricultural streptomycin sulfate can also be used if needed. 6. Physical Control:
In the first half of the year, consider covering the ginger fields with nets. This helps reduce soil moisture evaporation, limits irrigation frequency, and lowers humidity. It also prevents adult aphids from laying eggs and reduces pest infestation, thus minimizing damage to the ginger’s heart leaves. 7. Weather-Related Response:
After heavy rains, typhoons, or flooding, spray 20% Thiobacillus (Loncobacter) at 500 times dilution 2–3 times within 7–10 days to protect the plants from infection.
