Wheat Scab


Thursday, April 16th, 2020

Fusarium head blight or scab, caused by Fusarium graminearum, severity on wheat vary each year in Indiana. The disease is consistently present and of concern to growers. Cultivars with moderate resistance to Fusarium head blight do not always provide desirable levels of disease control in certain environments, and fungicides have become an important component in Fusarium head blight and DON (deoxynivalenol/vomitoxin) management plans in the region. An integrated approach that combines genetic resistance and fungicide application is desirable to achieve optimal management of Fusarium head blight. Continued evaluation of action thresholds and new products for our climate are needed in order to provide informed fungicide spraying decisions.
