New Brunswick maple syrup industry considers using BTK insecticide to combat forest tent caterpillar defoliation.

New Brunswick's maple syrup industry is considering using a biological insecticide, BTK, to control forest tent caterpillar defoliation in northwestern woodlands, affecting 120 sq km. About 30-40 syrup producers experienced infestations, potentially reducing production in the next spring. The industry plans to spray BTK in spring to prevent future issues, but funding and government approval are needed.
