How to prevent Diseases and pests of Wheat Seeds

How to prevent diseases and insects from wheat seeds? Please give guidance on wheat seed disease prevention and pest control can refer to the following methods: 1. Suitable Maidan seed coating agent produced by Swiss Syngenta crop Protection Co., Ltd., effective ingredients are 2.4% difenoconazole and 2.4% chlorpromazil, registered to control wheat smut, every 10ml agent mixed with 10kg seeds, diluted with water, the slurry and seeds will be fully stirred at the ratio of 1:50-100. Until the slurry is evenly distributed on the surface of the seed, it can be sown after drying. The drug has internal absorption and conductivity, the drug can be absorbed by wheat seeds and seedlings after mixing, has a long effective period, has a good effect of disease prevention and seedling protection, and can promote the healthy growth of wheat. 2. 2% tebuconazole seed dressing: mix the seed with 0.1% of the medicament and the wheat seed (10mur15g of the agent mixed with the 10kg seed), first add a small amount of water to make it pulpy, then stir it fully with the seed, so that the slurry is evenly distributed on the surface of the seed and dry in a cool place to sow the seed. It can control wheat sheath blight, total erosion disease and root rot. 3. Seed dressing with phoxim or chlorpyrifos: for the areas where underground pests such as mole cricket and grubs occur, 50% phoxim EC can be selected, 100g of 100jin seeds, 2.5kg mixed with water, or 48% chlorpyrifos EC according to 0.3% of the seed amount, and the seeds can be sown for 4 hours after mixing, which can effectively control underground pests. 4. The combination of soil treatment and chemical seed dressing can be used to control the serious occurrence of underground pests. Soil treatment with 3% phoxim granule 2.5kg ∕ mu evenly sprinkled on the ground, and then turned into the soil. In the dry farming fields of soybeans, corn and sweet potato in our county, because the food is rich, which is beneficial to the occurrence and reproduction of underground pests, the combination of these two methods can be used. Medicament seed dressing should pay attention to the following points: 1. Determine the types of pesticides according to the situation of diseases and pests in different fields, if there are fewer underground pests and more diseases, only fungicides can be used, such as local rice stubble wheat. If mixing occurs, both pesticides and fungicides can be used. If there are more underground pests, seed dressing and soil treatment should be combined, such as dry stubble wheat such as soybeans and corn fields. 2. Accurately control the dosage, do not blindly increase the dosage, lest lead to late emergence of wheat seedlings, slow growth, or even lack of seedlings and broken ridges, and the sowing depth should be 2-5cm. 3. Sow with mixing and sowing for a long time, do not put it for a long time. After mixing seeds with insecticides, it will be stuffy for 4 hours, and fungicides will be sown with mixing, otherwise it is easy to cause drug damage and must not be spread out in the sun. 4. Do a good job in protective measures to prevent human and animal poisoning. Click to get more wheat planting technology click to get more grain planting technology
