Garlic soft rot is a bacterial disease, low temperature and high humidity is conducive to disease. Early onset, poor drainage or overgrowth of the field is heavy. After the bacteria invaded the plants, they began to show symptoms from November. Occurred at the margin of the leaf margin or midrib, yellow-white streak was formed along the midrib, and when the humidity was high, the diseased part appeared yellow-brown soft rot, and yellow fungal pus appeared. The plant first attacked from the lower leaf and gradually expanded to the upper leaf, later. In severe cases, the whole plant died of yellow. Can take the following measures to prevent and control: Preferably, the preferred and selected garlic of the garlic is sown before sowing, and the garlic selected from the group consisting of virus-free, disease-resistant, large-grained, neat and non-injurious garlic is used. To improve soil fertility, we should choose loam flat, rich in soil organic matter, convenient drainage and irrigation, and the cultivation of loam soil with strong fertilizer and water holding capacity. When preparing the soil, you should deepen the cultivation and drying of the sun, so that you can practice Panasonic. Formula fertilization using formula fertilization, full application of decomposed organic fertilizer, cake fertilizer, increased phosphorus and potassium fertilizers, promote robust growth of seedlings, improve the disease resistance capacity of young garlic years before, to reduce the occurrence of physiological diseases. Suitable sowing time for sowing is generally in early October. After sowing, they are irrigated, covered with plastic film after watering, increasing the temperature and keeping the earthworms, reducing the number of irrigation, and can effectively reduce the spread of pathogenic bacteria by means of rainwater and watering. Chemicals control garlic treatment: Use 2.5% of the seed weight of 2.5% Shiloh suspension seed coating seed dressing to kill garlic body pathogens; with 50% carbendazim, 77% can be killed, 77% donin can be Wet powder dressing, seed dressing method is 100 grams of each agent of 5 kg of water, can be seed dressing 50 to 75 kg, evenly mixed and dried after sowing, control efficacy of soft rot up to 95%. Soil treatment: For the land where soft rot has already occurred, spray the sowing trench with 3% of Weifendan suspension or 600% of Daning wettable powder 600 times, spray 100 kg per acre, and sow after spraying; use sulfuric acid Copper, quicklime, and wood ash were mixed at a ratio of 1:1:100 and applied to the garlic ditch. Foliar spray: If the above measures still occur diseased plants, can be sprayed in the early stages of the disease in a timely manner 72% of the streptomycin soluble soluble powder 400 times, 77% can kill WP 500 to 800 times, every 7 to 10 Spray once a day, spray 2 or 3 times, and apply 50% carbendazim, 75% chlorothalonil wettable powder 500 to 800 times, or 50% thiophanate-methyl wettable powder 600 to 1000 times to root rhizomes. For garlic fields with high soil moisture, early application of pesticides is better. Natural, No-addition, Fig series products WEIHAI ACCELERATE BIOTECHNOLOGY CO, LTD , https://www.accelerfig.com
