Abstract
Taking the 2nd instar Plutella xylostella larvae as experimental worm,the synergism of six potentiators(NaH2PO4,CuSO4,Success,Boric acid,Citric acid,Abamatin)on Bt 20 was studied.The results showed that Success had the best synergism effect on Bt 20.The corrected mortality to Plutella xylostella reached to 42.2%～95.6% on the second day,the third day's corrected mortality reached to 48.9%～100%,and the fourth day's corrected mortality could reach to 50.2%～100%.
