Wheat seed dressing can prevent diseases
Wheat seed dressing can prevent full-bleeding, root rot, sheath blight, scattered black ear and other soil-borne, species-borne diseases and some insect pests. Care should be taken when dressing seed: 1. The type of medicine should be determined according to the occurrence of pests and diseases. If the occurrence of wheat seedling pests is very light, the disease occurs more severely, and only the fungicides can be used for seed dressing, and pesticides do not need to be used; if pests and diseases are mixed, they must be seeded with insecticides, and must be seeded with fungicides. If the occurrence of heavy pests in the ground, seed dressing by medicine can not achieve the desired control effect, seed dressing and soil treatment methods should be taken to prevent wheat pests. 2. To accurately grasp the amount of pesticides. Prevention and control of wheat underground pests, 50% phoxim can be used to prevent diseases such as wheat smut, full-bleeding disease, powdery mildew, and sheath blight. 15% of Triadimefon can be used and 6% of Riken Suspension can be used. Mixed wheat seeds. Some farmers use “estimate†drugs when dressing wheat seeds and blindly increase the amount of drugs used. This is undesirable. Practice has proved that if wheat is used with Triadimefon, Phoxim and other pesticides, if the amount is too large, it will cause obvious phytotoxicity to wheat, which will cause the emergence of wheat to be delayed, and the growth will be slow. In severe cases, it will even appear to lack of seedlings, so it should be particularly note. 3. Pay attention to the seed dressing method. For wheat seed dressings such as phoxim, the pesticide should be diluted with water first, then mix well with the wheat seeds, and cover the stuffy stuff before planting. Wheat is dressed with quintozene, triadimefon, and Rickettsia. The seed should be sprayed with water until it is moist, and then the agent is evenly mixed on the seed, and then immediately sown or dried after sowing. If it is necessary to use insecticides for seed dressing and seed dressing with fungicides, insecticides should be mixed first, and then mixed with fungicide, and then immediately sowed. 4. It is not allowed to stay for a long time with the accompanying broadcast. After wheat is seeded with insecticides, it usually takes 2 to 3 hours, up to 5 to 6 hours, and the seeds are sown immediately after being absorbed by the wheat seeds. Generally, after wheat is sterilized with a fungicide, it should be immediately sown or dried immediately after being dried. Some peasant households spend a long time boring after wheat seed dressing, or they will not broadcast after dressing for a long time, which will also cause phytotoxicity to wheat. If wheat is spread in the sun after dressing with fungicides, the disease prevention effect will be significantly reduced. In addition, we must strictly follow the seed dressing practices to prevent human and animal poisoning.
