Barley planting: how to control barley stripe disease?

How to prevent and cure barley stripe disease? What are the hazards of barley stripe disease? Please tell me about the harm of barley stripe disease: this disease is mainly harmful to leaves and leaf sheaths. The disease can appear at the seedling stage, with light yellow spots or short stripes, and the disease is the most serious at the jointing and heading stage. the typical symptom is the formation of slender spots from the base of the leaf to the leaf tip, parallel to the leaf vein, or continuous or intermittent. The color of the spot changed from yellow to brown, and then withered. Around the disease spot will also fade green and turn yellow, so that the diseased field is yellowish brown, the diseased plant dies ahead of time or short, can not heading or bending deformity, can not bear fruit or is not full. It seriously affects the yield and quality of malting barley. When the humidity is high, a black mildew layer grows on the diseased leaves, which can spread a large number of conidia. If the barley is blooming, it will infect the floral organ and make the seeds carry bacteria. Barley stripe disease is a fungal disease. The pathogen lurked in the seeds of barley and became the source of the disease in the second year. Another characteristic of this disease is that it infects the seedlings only at the seedling stage of barley, and then expands in the body, so that the leaves that grow later continue to suffer from the disease. Prevention and control methods of barley stripe disease: soaking seeds in 1% lime water for 48 hours, drying and sowing seeds; method 2, 10% dithiocyanomethane (soaking seed ling) 15ml, adding water 1.5kg to 2.0kg, spraying evenly on 50kg barley seeds, spraying and mixing, stuffing seeds for 8 hours, drying and sowing. Method 3, 2% tebuconazole (Likexiu) seed dressing agent 100g mixed with 100kg barley seeds Method 4. Use 3% dimethoconazole (oxyezole) suspension seed coating agent 330ml, 10% difenoconazole 200g or 25% biphenyl triazole 150g mixed barley seed 100kg. Some people also use Jinlishi (propiconazole) EC, dimethopril (diniconazole) EC, Spock (imidamide), triazole and other seed dressing and achieve good disease prevention results. In addition, the methods of planting disease-resistant varieties, establishing disease-free seed fields, promoting rapid unearthing of seeds and shortening susceptible time, such as drying seeds for 1-2 days before sowing, early sowing before winter, late sowing in spring and fine soil preparation, proper shallow sowing can reduce the disease.
