Wheat School: Fusarium head blight 101 — field history & weather combine to create risk

Fusarium head blight grows on old, infected crop residues, which is the primary source of this disease. Weather conditions have also been ideal for disease development. While these are the ideal conditions for the pathogen to proliferate, anywhere between 10 and 30 degrees can see activity, says Dr. Kelly Turkington of Agriculture and Agri-Food Canada in this Wheat School episode.
