First, ginger stem rot spread routes
The pathogenic bacteria mycelium lurks on diseased ginger and the sick body for overwintering, or the mycelium and chlamydospore are overwintering in the soil, and the conditions are appropriate to cause the disease. It usually begins in May, and the germ-bearing ginger can still continue to develop after the harvest, continuing until the seedlings are planted in March of the following year.
Second, ginger stem rot disease conditions
High temperature and high humidity are conducive to the occurrence of ginger stalk rot, the appropriate incidence temperature is 20 °C -25 °C. Ginger is hi light and drought-resistant plants, ventilation and poor light transmission of the land susceptible to disease. Yellow mud loam, sticky soil is prone to disease. The number of field bacteria accumulated in the continuous cropping plots was relatively heavy.
Third, ginger stem rot control methods
1, choose no pests, no rotten ginger, to prevent the spread of pests and ensure the seedlings full seedlings. When sowing, soaking with a new high-fat membrane soaking for 4-5 minutes, drying after sowing can be heat preservation, moisturizing, swelling, increase seed germination rate, so that seedlings robust.
2, soil disinfection. Disinfectant and fine soil are applied to the soil in the disease block and soil preparation. If it is in acidic soils, applying lime for disinfection can prevent soil-borne diseases.
3, scientific fertilizer. Ginger prefers soil with good air permeability, and can be mixed with potassium sulfate no-tillage fertilizer and composted soil-fertilizer.
4, ridge work scaffolding. The use of bamboo poles to build an adult frame to promote ventilation, light and moisture flow, promote leaf photosynthesis, disease prevention and control. In case of early onset, use fungicides + targeted drugs for timely prevention and treatment.
How to Prevent and Treat Ginger Stem Rot Caused by Ginger Stem Rot
In the early stages of the onset of stem rot in ginger stems, water-stained spots of varying sizes appear at the base of the stem, gradually expanding, and the leaves are yellow. The lesions surround the base of the stems one week later, causing the basal tissues to decay gradually. Therefore, ginger must be prepared. Stem rot prevention and control work. With regard to the prevention and control of ginger stalk rot, agricultural materials Xiaobian introduced it to everyone. I hope that Xiaobian’s sharing will help everyone.
