WEBINAR: Grappling with cut flower diseases

April 23, 2019  By Greta Chiu

Speaker: Dr. Janna Beckerman, Purdue University


Differing from potted crop productions, cut flower growers can sometimes struggle more, or differently, with diseases. Learn how to best prevent and manage some common culprits, including powdery mildew, fusarium, botrytis, leaf spots and more, in this different context.
