| Abstract: | In order to evaluate the control effect of dinotefuran 20% SG against rice planthopper, the field efficacy trials were carried out. The results showed that dinotefuran 20% SG had good control effect on rice planthopper, with good quick-acting and persistence efficacy. Therefore, it had a good application prospect in rice. The application stage should be the peak of nymph occurrence of the rice planthopper. The optimum dosage of dinotefuran 20% SG was 450 g/hm2. |
