To explore the field efficacies of different biological pesticides and their mixtures with Bacillus thuringiensis, the field efficacy trials were compared. The results showed that spinetoram 60 g/L SC, LeNPV+Bacillus thuringiensis WP had better efficacies on diamond-back moth. The control effects of the mixtures of biological pesticides and Bacillus thuringiensis increased significantly. The recommended dosages of application were spinetoram 60 g/L SC 675 mL/hm2, LeNPV+Bacillus thuringiensis WP 1 125 g/hm2, and the additive amount of Bacillus thuringiensis 32 000 IU/mg WP was 750 g/hm2.
