Summary

Bt aizawai spores and parasporal crystals were added to acidic natural and autoclaved soil. No significant loss of parasporal crystals insecticidal activity was detected over 250 days in autoclaved soil; however, a rapid decrease of activity was observed in natural soil. This suggests that soil microorganisms were responsible for the loss of insecticidal activity.

Comments

This study did not use Bt from transgenic crops.
