An overwintering red raspberry cane with a Cane Botrytis lesion. The dark bumps on the surface of the cane are Botrytis sclerotia (overwintering survival structure). We have seen Botrytis spores produced from the sclerotia on dormant plants during the winter and into the spring months. We are studying the fate of spores produced during the pre-season to determine if they are important in the Gray mold/Botrytis disease cycle.
