Executive Summary

Three biologically-based pest management products were assessed for their efficacy in reducing balsam fir sawfly (Neodiprion abietis) larval numbers in a field trial using ground-based application technology. The products used were Neemix 4.5 (a botanical product derived from the neem tree, Azadirachta indica), Bacillus thuringiensis ssp. israelensis, and a naturally-occurring virus pathogen of the balsam fir sawfly. All three products showed sufficient efficacy to warrant further investigation.
