Vegetable seed disinfection method

In the prevention and control of vegetable diseases, seed disinfection is used to control the bacteria inside and outside the seed and the bacterial contamination during the seedling stage, and the results can be achieved with half the effort. Seed disinfection of fungal diseases 1. Formic acid mixture: This product is a mixture of 20% thiram and 20% benzoate. Cucumber wilt, bacterial wilt and seedling blight were soaked for 30 minutes with 20-fold solution; tomato wilt was controlled with 200-fold solution for 30 minutes. The above diseases and watermelon wilt can also be seeded with 0.4% of seed weight. 2. Fujia Mixture: This product is a mixture of 30% thiram and 50% thiophanate-methyl. When controlling tomato and watermelon fusarium wilt, use 200 times liquid soaking for 20-30 minutes; when controlling cucumber fusarium wilt, blight and seedling blight, use 200 times liquid soaking for 30-60 minutes. The above-mentioned disease control can also be seeded with 0.5% to 1% of seed weight. To control eggplant brown leaf disease, verticillium wilt, blight, sweet pepper anthracnose, and disease when soaked with 200-400 times liquid for 30 minutes; tomato leaf mold and carrot black spot use 1% seed weight seed dressing. 3, Fumei double: 80% effective content. The control of soybean blight is 0.3%-0.5% of seed weight. 4, Captan: effective content of 80%. Control the sowing of the nightshade of solanaceous and melon vegetables at the seedling stage, and use 0.2%-0.4% seed weight for seed dressing. 5, rust amine: effective content of 75%. To prevent tomato seedlings such as tomato, eggplant, bell pepper, cucumber, watermelon, and carrot, seed dressing is applied with 0.4% of the weight of the seed; in addition to spinach damping-batch, the seeds may be soaked in 200-fold solution for one hour, or 1000 times liquid soaking for 24 hours. Seed Disinfection of Viral Disease 1. Trisodium Phosphate: Immerse seeds such as tomato, watermelon and gourd with 10% solution for 15-20 minutes, then rinse with water. 2, constant temperature dry heat: constant temperature 70 °C dry heat treatment of tomatoes, cucumbers, watermelons, cabbage, cabbage and radish and other seeds, can prevent viral infection, and concurrent treatment of fungal and bacterial diseases. Dry heat-treated seeds should be dried. Chen seeds should not be treated. Treated seeds cannot be preserved for a long time. China Agricultural Network Editor
