【Abstract】 In this context, the effect of several kinds of seed coating applied in the rice fields was studied. The result indicated that the seeds coated with A B2 seed coating showed faster field emergence, higher seedling stand percent and better seedling growth than the others. The result also demonstrated that the A B2 seed coating possessed the best control effect on Stenchaetothrips biformis (Bagnall) with 50.05%-84.63% among all of the treatments and long persistent to control the pests, and that it’s harvest yield was increased by 26.47% compared with that of the ck treatment.更多还原
