GENERAL INFORMATION
for Bacillus thuringiensis Berliner subsp. aizawai

Description: A specific strain of the bacterial insecticide Bt selected for its control of Lepidopteran larvae, particularly those of the Spodoptera group and insects that have developed resistance to Btk

Appearance and life cycle: Bacillus cultures are found in nature in one of two states. They are found either as vegetative cells that are actively growing and dividing or as spores.
