| Abstract: | Five insecticides Chlorfenapyr, Cascade, Larvin, Redan, Regent have been tested to control Spodoptera exigua. The results showed that Chlorfenapyr not only had fast and high control efficacy (90.51 %～92.56 %) to Spodoptera exigua (Hübner) in 7 days after treatment but also lasted long period (the control efficacy is still 86.33 %～91.30 % in 10 days after treatment); Cascade had better control efficacy (92.13 %) to the pest in 10 days after treatment. Redan, Regent had lower control efficacy. Control efficacy of Larvin is 92.13 % in 7 days after treatment. |
