Development and current status of Bacillus thuringiensis for control of defoliating forest insects

Abstract

In Canada, use of high-potentcy formulations (12.7-16.9 BIU/L) applied undiluted at 30 BIU in 2.4 L/ha or less has significantly reduced but not eliminated initial constraints of high treatment costs and inconsistent efficacy. Current research is focused on further reducing these constraints. -from Author
