| Abstract: | It is effective to control Pieris rapae and Pluttella xylostella by dilution of 1 000 aqueous of dust of Bacillus thuringiensis(Bt) strain H3136 mutant. Control peak with the highest mortality of 97.5% and 79.8% respectively appears in 5～7 d and 2～5 d after spraying. Mortality of Pieris rapae and Pluttella xylostella for BtH3136 is better than that for omethoate. In view of effective and no pollution of environment, BtH3136 preparation will completely be replaced for chemical pesticides in the production of no pollution of vegetables. |
