Abstract

The compatibility of Bacillus thuringiensis (B.t.) with 27 chemical insecticides representing organophosphorus and carbamate insecticides, pyrethrins, chlordimeform, urea derivative, and antifeedant were studied by way of their effects on germination of the bacterial spores, replication of vegetative cells and spore staining, and refractive index characteristics.

The results showed that: (1) Carbamates were generally more compatible with Bacillus thuringiensis than were the other insecticide groups tested. (2) Technical formulations were less harmful to the bacteria than wettable powders which were less harmful than emulsifiable concentrates. (3) Of the 27 pesticides, those most compatible with B.t. were Orthene®, Dylox®, Lannate®, Sevin®, Zectran®, and Dimilin®. These insecticides are considered recommendable for use in integrated control operations with Bacillus thuringiensis if the target insects are susceptible to them and provided that due regard is given to the environmental implications of their use.
