Improper handling of wheat seed dressings not only does not prevent disease and insects, but it may also lead to slow emergence of wheat, uneven emergence, and even affect the normal growth of wheat seedlings. Under normal circumstances, the following points should be noted in wheat seed dressing before sowing:
Determine the type of pesticides according to the local pest occurrence. If the local wheat seedling pests occur very lightly and the diseases are severe, only the fungicides can be used for seed dressing, and pesticides do not need to be added; if pests and diseases are mixed, pesticides should be used. Seed dressing, but also with fungicides seed dressing; If the occurrence of heavy underground pests, seed dressing by drugs can not achieve the desired control effect, should be taken with seed dressing and soil treatment methods to prevent wheat pests.
Accurately understand the amount of pesticides some farmers in the wheat seed dressing estimated drug use, blindly increase the amount of medication. Practice has proved that if wheat is used in the dressing of Triadimefon, Phoxim, etc., if the amount is too large, it will cause phytotoxicity, but it will cause the emergence of wheat to be delayed and growth is slow, and the emergence of ridges will occur.
Pay attention to the seed dressing method. For wheat, use phoxim and other seed dressings. Diluted the pesticide with water first, then mix well with the wheat seeds, cover the stuffy stuff and sow. 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.
With the broadcast, can not be long set
After wheat has been seeded with insecticides, it usually takes 2 to 3 hours for boring and 6 hours for long, and the seeds are immediately sowed after being absorbed by wheat seeds. Generally, after wheat is sterilized with a fungicide, it should be immediately sown or dried immediately after being dried. Some peasant households spent a long time boring on wheat seed dressings, or kept sowing for a long time after dressing, which could easily cause phytotoxicity.
