Strengthen the cultivation and management 1, before sowing optimization and selection of garlic, as far as possible the use of virus-free, disease-resistant, pest-free garlic species. 2. Before the election, the vegetable plot should be a non-onion garlic vegetable plot, and the loam soil should be planted with a flat topography, convenient drainage and irrigation, rich soil organic matter, and strong fertilizer-holding capacity. When preparing the soil, you should deepen the cultivation and drying of the sun, so that you can practice Panasonic. 3, the use of formula fertilization, full application of organic fertilizer, cake fertilizer, increased application of phosphorus and potassium fertilizer, promote seedlings robust growth, improve the resistance of the disease before the young garlic period, in order to reduce the occurrence of physiological diseases. 4, timely sowing. Grasp the appropriate sowing date, soaking water after sowing, covering the film after watering, increase the temperature, protect the earthworms, reduce the number of irrigation, and can effectively reduce the spread of pathogens by rain, watering.
Chemical control 1, garlic treatment: Use 0.25% of the seed weight 2.5% Shiloh suspension seed coating seed dressing, can kill garlic pathogens; with 50% carbendazim seed dressing, seed dressing method is each Pharmaceutic 100 grams of water 5 kg, can be seed dressing 50-75 kg, evenly mixed and dried after sowing, the control effect on soft rot up to 95%. 2. Soil treatment: This method is applicable to the land where soft rot has already occurred. Spray the seeding ditch with 3% enemy Weidan suspension agent or 77% Donning wettable powder 600 times liquid, spraying 100 kg per mu, after spraying That is sowing; with copper sulfate, quicklime, grass ash mixed in a ratio of 1:1:100, applied to the garlic ditch. 3, foliar spray: If the above measures still appear diseased plants, can be sprayed in the early stages of the disease can be quickly sprayed 77% of the WP can be 500-800 times the liquid, spray every 7-10 days 1, even spray 2-3 Times; 75% chlorothalonil wettable powder 500-800 times irrigation rhizomes, for soil moisture in the garlic field, as soon as possible better control effect.
