| Abstract: | The wettable powder of Bacillus thuringiensis with potency of 50000IU/mg was developed by Hubei Biopesticide Engineering Research Center with highly toxic B. thuringiensis strain NBIV-330 obtained from the strain collection through screening with resistant Plutella xylostella. The product is used to prevent and control resistant diamond-diamond-moth, the control effect reaches over 85% with the dosage of 30～50 g/mu 3 days after treatment. |
