Concerns Over Black Cutworm in Ontario in 2011 – Tracey Baute, OMAFRA

Rain isn’t the only thing those constant storms have been carrying into Ontario. States south of Ontario have reported large captures of black cutworm moths, and some of those same moths have been riding the storm fronts into Ontario and laying eggs.
