Safety of Bacillus thuringiensis for earthworms

Authors: Benz, G., Altwegg, A.
Journal, Volume, Year: Journal of Invertebrate Pathology, volume 26:125-126, 1975
Summary

Experiments were done to evaluate the effects of two Bt preparations (Dipel and Bactospeine) on earthworms (Lumbricus terrestris) in a forest environment. Three concentrations of Dipel and one concentration of Bactospeine were applied on a 9 square meter plot. Mean densities of earthworms in each plot were determined prior to and after Bt treatment. None of the Bt treatments had an adverse effect on earthworm populations.

Comments

This was one of the early studies looking at non-target effects of Bt.
