Study on adaptability and using effect of new superfine powder corn seed coating agent in northeast sowing area. The results showed that compared with the uncoated blank control, the germination potential and germination rate of corn seed dressing increased by about 5% and the total number of roots increased by 4%. The seedling fresh weight, stem diameter, dry weight and the blank Compared with the control has obvious advantages, later can increase the yield of corn; especially in the prevention of underground pests in northern best, up to 94%, significantly better than other commercially available seed coating in Northeast China. Superfine corn seed coating agent in the spring sowing in Northeast strong adaptability, no toxic side effects during the whole growth period.
