【Abstract】 The control of rice thrips in rice seedlings and rice planthoppers in rice field was studied by different application modes(irrigating the root,spraying upon the leaf) and different concentrations(500~1000 times diluted solution) of 25% Thiamethoxam SC which was applied once at seedling stage.The results showed that 25% Thiamethoxam SC had good control effect on rice thrips in seedlings,while it had low control effect on rice planthoppers in transplanted rice plants.Application of 25% Thiamethoxam SC could well improve the quality of rice seedlings.更多还原
