Garlic soft rot should be prevented as soon as possible

Garlic soft rot is a bacterial infection disease, the pathogen is carrot soft rot Escherichia coli, mainly through the pathogen on the disease residue in the soil for re-infection. The disease of autumn sowing garlic began in November, such as low-lying topography in the field, too much rainfall and watering, poor drainage, serious disease in large humidity in the field, serious disease in sewer and sunny border cultivation, and severe disease in garlic varieties with poor cold resistance. the disease is serious when sowing too early and applying too much chemical fertilizer and growing too much a year ago. Comprehensive control should start from sowing. 1. The best species of garlic are virus-free, disease-resistant and disease-free. two。 It is appropriate to choose flat terrain, convenient drainage and irrigation, rich soil organic matter, strong ability to preserve fertilizer and water, and the previous crop is non-onion garlic soil to grow garlic. And fine soil preparation, to achieve the upper loose and lower solid, in order to block the source of the disease and avoid the conditions of the disease. 3. Fully apply mature high-quality organic fertilizer and cake fertilizer based on phosphorus and potassium fertilizer to improve the disease resistance of the plant and reduce the occurrence of physiological diseases. 4. Chemical control. ⑴ garlic treatment: seed coating with 2.5% suspension seed coating agent with 0.25% seed weight before sowing can kill garlic pathogens; seeds can also be mixed with 50% carbendazim or 77% carbendazim or 77% Douning wettable powder, seed dressing method is 100 grams of each agent mixed with water 5 kg, seeds can be mixed 50-75 kg, evenly mixed to dry before sowing. ⑵ soil treatment: this method is suitable for plots where soft rot has occurred. The sowing ditch can be sprayed with 77% Douning wettable powder, 100kg per mu, and sown immediately after spraying, or copper sulfate, quicklime and plant ash are mixed in the proportion of 1 ∶ 1 ∶ 100 and sprinkled in the garlic ditch. 5. Early prevention and treatment after the onset of the disease. After adopting the above measures, the occurrence of garlic soft rot can be prevented and treated. If it still occurs, it should be sprayed in time. At the initial stage of the disease, 77% Donin 600 times solution and 3% Zhongshengmycin 800 times solution were sprayed once every 7-10 days for 2-3 times.
