Integrated Pest Management Options

Fusarium head blight infection in oat is very difficult to identify. Bleached florets are often caused by high temperatures rather than Fusarium. Examine developing panicles carefully for any development of pink colouration. Avoid planting oat into corn residue.

For more information, see FUSARIUM HEAD BLIGHT (Fusarium graminearum), on page 60.
