doi:10.16409/j.cnki.2095-039x.2020.06.015

Abstract

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.

Key words: Bacillus thuringiensis, resistant Plutella xylostella, application and extension

CLC Number:

S476.1
