Vegetable seed disease prevention treatment coup
The seeds of vegetables often carry bacteria. In many cases, in order to reduce the disease at the seedling stage, some disinfection measures are taken on the seeds in the early stage of planting. The disinfection of the seeds can kill most of the bacteria and pathogenic fungi on the seeds, and the virus is inactivated. In order to prevent the occurrence of diseases, and to improve the germination rate of the seeds and the disease resistance at the seedling stage. Therefore, in the vegetable production, seed treatment should be done according to the disease prevention needs. Today, Cherry Little Girl teaches everyone how to deal with vegetable seeds! First, prevention and treatment of bacterial diseases (1) Soaking in warm soup Determine the temperature and time of soaking water according to the type of vegetables. The pepper seeds were soaked in warm water at 55 ° C for 30 minutes. The seeds of the melon seeds were generally soaked in warm water at 55 ° C for 20 minutes. The seeds of cabbage, broccoli and radish were soaked in warm water at 50 ° C for 20 minutes, and the seeds of the beans were soaked in warm water at 45 ° C for 15 minutes. (2) Soaking seeds Pepper seeds were soaked in 1% copper sulfate solution for 5 minutes. Cucumber, kale, and broccoli seeds were soaked for 2 hours with 72% agricultural streptomycin 1000 times solution. The radish seeds can be soaked for 5 to 20 minutes with 45% Dyson zinc water solution 1000 times, or soaked with 75% agricultural streptomycin 1000 times for 2 hours. For the prevention and treatment of melon bacterial diseases, soak seeds with 10% sodium chloride 10~30 times for 30 minutes, then wash them with water. (3) Chemical dressing The pepper seeds can be seeded with 50% dikesone powder with a seed quality of 0.3%. Cucumber, kale, broccoli and radish seeds can be seeded with 50% Fumex WP of 0.4% seed quality. The radish seeds can also be seeded with 35% metalaxyl seed dressing with a seed quality of 0.3%. To control the bacterial disease of kidney bean, seed dressing can be carried out with 50% thiram double wettable powder or 70% dikesone raw powder with a seed quality of 0.3%. Second, prevention and treatment of fungal diseases (1) Soaking seeds in warm soup Seeds of cucurbits and solanaceous seeds were soaked in warm water at 55 ° C for 15 to 20 minutes, seeds of celery were soaked in warm water at 48 ° C for 30 minutes, seeds of beans were soaked in warm water at 45 ° C for 10 minutes, and green onions and onion seeds were soaked in warm water at 50 ° C for 25 minutes. (2) Soaking seeds 1. For the prevention and treatment of melon (cucumber, watermelon) wilt and eggplant yellow wilt, cotton rot and bean anthracnose, soak seeds with 40% formaldehyde (formalin) 100 times for 30 minutes. 2. Cabbage, tomato, melon seeds, soaked in 50% carbendazim 500 times solution for 1~2h, then removed, washed with water and germinated sowing, can prevent white spot black spot disease of cabbage and tomato early (late) disease And melon white powder disease. 3. Dip cabbage, kidney bean and melon seeds with 50% dasen ammonium 200~300 times for 20~30min, remove and wash with water, and control the downy mildew and bean anthracnose. 4. Soak the tomato seeds for 3~4h, then dip in 0.3%~0.4% copper sulphate solution for 5min to prevent tomato early blight. 5. Control of pepper blight and anthracnose can be soaked in 1% copper sulfate solution for 30 minutes. 6. Control cucumber wilt can be soaked with 2%~3% bleaching solution for 30~60min. 7. Control the bean wilt with 60% anti-mildew ultra-fine powder 600 times liquid soak for 30min. 8. Prevention and control of green onion and onion purple spot can be soaked in 0.1%~0.2% potassium permanganate solution for 20min, and the melon wilt can be soaked in 0.1%~0.2% potassium permanganate solution for 0~60min. 9. Control cucumber sclerotinia disease Wash cucumber seeds with 10% saline. 10. Dip the melon and solanaceous vegetable seeds with 2% sodium hydroxide solution for 10~30min, then wash and sow with water to control various fungal diseases and viral diseases. 11. Soak seeds with 0.1% methyl thiophanate for 2~3h, and wait until they are fully dried before sowing to prevent fungal diseases such as blight and downy mildew. (3) Chemical dressing 1. Control cucumber plague and cabbage, radish, spinach downy mildew, seed dressing with 50% Fumex WP of 0.3% seed quality. 2. For the prevention and treatment of cucumber scab, 50% carbendazim WP can be used for seed dressing with 0.3% seed quality. 3. For the prevention and treatment of spinach downy mildew, 25% metalaxyl WP can be used for seed dressing with a seed quality of 0.3%~0.4%. 4. For the prevention and treatment of melon fungal diseases, seedlings of Luheng No. 2 WP can be used with a seed quality of 0.4% to 0.5%. 5. For the prevention and treatment of black spot of cabbage, seedlings with 0.2% to 0.3% of seed quality or 50% speeding can be used. Third, prevention and treatment of viral diseases (1) Soaking seeds in warm soup For the prevention and treatment of viral diseases, it can be soaked in warm water of 60~62 °C for 10 minutes. (2) Soaking seeds After immersing the seeds in water for 4 hours, immersing them in 10% trisodium phosphate solution for 20~30 minutes, then removing them, washing them with water and germination, and controlling tomato and pepper virus diseases. Soaking seeds with potassium permanganate solution for 10~30min can alleviate and control the disease of eggplant vegetable virus and early blight. (3) Dry heat treatment The virus can be prevented by treating the seeds under a dry heat condition of 70 ° C (constant temperature drying oven) for about 72 hours. Fourth, operational requirements (1) Soaking seeds in warm soup The water temperature is strictly controlled according to different vegetable types. To be heated evenly for a specified period of time. (2) Soaking seeds and seed dressing Concentrations and doses must be performed as standard. Mix the medicine evenly. After soaking the seeds, rinse the seeds with water to remove the pesticides on the seeds to avoid drug damage after sowing, affecting seed germination and seedling growth.   (3) Dry heat treatment To grasp the applicable varieties, strictly control the temperature and time as required. The above is the coup for the vegetable seed disease prevention treatment brought to you by Cherry Little Girl. Is it for you to open your eyes? I hope this article can help our farmers friends!
