| Abstract: In order to screen out effective and safe pesticides for controlling Bemisia tabaci in greenhouse and reduce the use of chemical pesticides, seedling stage tomato of greenhouse was used as experimental material. Four treatments were set up, which contained 1.25, 1.67, 2.08 mL/kg 5% d-limonene SL, 0.17 mL/kg 25% thiamethoxazine WP (conventional chemical agent) and clear water was control. The results showed that 1.67 mL/kg 5% d-limonene SL had better control effect and was suitable for popularization. |
