The following introduces several common diseases of large ginger and their prevention and control methods:
Ginger blast: mainly spread by irrigation water and underground pests, and can occur from the sprouting and emergence of seed ginger to before the harvesting of ginger. This disease mostly occurs in high-temperature, frequently rainy, and waterlogged fields.
Prevention and control: disinfect the seed ginger by soaking it for 6 hours in a 800-fold dilution of "Keshade 2000" (that is, 40 grams of "Keshade 2000" mixed with 32 kg of water); when diseased plants are found, dig them out and burn them promptly, and disinfect the ginger holes with quicklime. In the early stage of the disease, drench the roots with a 500-600-fold dilution of "Keshade 2000" and combine it with "Keshade 200" + "Jinyunda-120". Spray the leaves with a 1000-fold dilution for prevention and control.
Ginger spot disease: Prevention and control: spray fungicide in the early stage of the disease, using a 800-1000-fold dilution of "Puning" or a 1500-fold dilution of Cuili for foliar spraying, and apply the fungicide again after an interval of 7-10 days.
Ginger anthracnose: Prevention and control: spraying a 600-800-fold dilution of "Yunsheng" before the disease occurs can effectively prevent its occurrence. In the early stage of the disease, use "Cuili 1000-fold dilution + Jinyunda-120" diluted 1500-fold for foliar spraying for prevention and control, and spray again after an interval of 7-10 days, for 2-3 consecutive times.
Ginger leaf blight: Prevention and control: before the disease occurs, spray the leaves with a 600-800-fold dilution of "Yunsheng" + a 1500-fold dilution of "Jinyunda-120", spraying 2-3 times at an interval of 7-10 days for prevention, which can also prevent multiple diseases at the same time. In the early stage of the disease, use a 1000-fold dilution of "Cuili" + a 1500-fold dilution of "Yunda-120" for spraying for prevention and control.
Ginger bacterial soft rot: Prevention and control: in the early stage of the disease, drench the roots with a 500-fold dilution of "Keshade 2000" solution (that is, 40 grams of "Keshade 2000" mixed with 20 kg of water), and combine it with a 1000-fold dilution of "Keshade 2000" + a 1000-fold dilution of "Jinyunda-120" for foliar spraying, and apply the fungicide again after an interval of 7-10 days.
Ginger Fusarium wilt: Prevention and control: drench the roots with a 500-600-fold dilution of "Keshade 2000" + a 1000-fold dilution of "Jinyunda-120", applying 0.2 kg of the solution each time, once every 7-10 days, for 2-3 consecutive times.
Ginger eye spot disease: Prevention and control: in the early stage of the disease, use a 1000-1500-fold dilution of "Cuili" (that is, 10-15 grams of "Cuili" mixed with 15 kg of water) or a 1000-fold dilution of "Keshade 2000" (that is, 15 grams of "Keshade 2000" mixed with 15 kg of water) for foliar spraying, and spray again after an interval of 7-10 days.
Ginger damping-off: mainly damages seedlings. In the early stage of the disease, the base of the seedling stem near the ground turns brown, causing damping-off.
Prevention and control: disinfect the seed ginger by soaking it for 6 hours in a 800-fold dilution of "Keshade 2000" (that is, 40 grams of "Keshade 2000" mixed with 32 kg of water). When diseased plants are found, dig them out and burn them promptly.
Soil disinfection: 1. Mix "Hymexazol" + "Thiram" at a ratio of 1:1, dilute 1000-fold and mix into the soil; 2. Mix "Keshade 2000" + "Zineb" at a ratio of 1:1 and dilute to a 500-fold solution (that is, 40 grams of "Keshade 2000" + 40 grams of "Zineb" mixed with 20 kg of water) to drench the roots.
