It is good to grow strawberries in greenhouses, and the area is also increasing year by year. The high humidity in the greenhouse can easily induce the occurrence and harm of the blight disease. The disease can harm various parts of the strawberry, but the flower buds, young buds and young leaves are the main damage. Generally, the strawberry in the greenhouse occurs. In addition to harming strawberries, shoot blight can also harm a variety of crops such as vegetables and soybeans. Prevention and treatment of bacterial blight should be based on prevention, and comprehensive control measures should be taken according to the characteristics of hazards. Generally, good control results can be achieved. Try to avoid cultivating strawberries in the open field or in the shed where the blight has occurred. For long-term continuous cropping, be sure to seize the high temperature in summer and use solar energy to disinfect and sterilize the shed. Cultivate disease-free seedlings. The establishment of disease-free seedling breeding bases, and the cultivation of disease-free seedlings can reduce the incidence of disease, and strawberry plants cannot be propagated with diseased plants as mother plants. When planting, the density should be reasonable, and appropriate sparse planting cultivation. Covering the black plastic film early in the row before budding is beneficial to inhibiting the germination of mycelium and reducing the effective source of bacteria. And pay attention to field hygiene, timely removal of old leaves and diseased leaves, found that diseased plants were removed in time, brought out and burned. Master the regulation of humidity. Reasonable irrigation, ensure ventilation, reduce the indoor humidity in the shed, and prevent the occurrence of bud blight caused by difficult humidity control. Pharmacy control. Prevention and treatment of blight can be combined with other diseases. In the initial stage of the disease, 10% polyoxin 600-800 times solution, or 10% liquan 300 times solution, or diphenanthrene 600 times solution can be used to irrigate roots or spray. It is also possible to use 24% Jinggangmycin A 1000 times solution plus 1000 times CFU wettable powder containing 100 billion CFU spores per gram, which has better effect. In addition, the following fungicides are effective in controlling strawberry bud blight. 25% thiafuramide suspension agent 1500-2000 times liquid, or 30% oxafuran water agent 1500 times liquid spray or irrigate roots. Once every 7 days, a total of 2 to 3 times, the dosage of severely ill fields should be appropriately increased. In the shed, strawberries can be affected. You can use 150 to 180 grams of 5% chlorothalonil dust per acre, divided into 5 to 6 places, lit the closed greenhouse overnight in the evening, and smoked 2 to 3 times, with an interval of 7 days.
