Data from 19 years of trials examines fusarium head blight in wheat

Wheat_HeadScab_blog1As growing season approaches the issue of fusarium head blight (FHB) in wheat and what can be done to control it, cannot be overlooked. In a recent study, one pathologist and his team looked at nearly two decades of fungicide trials in an effort to find the best way to control the disease.

The findings were presented at the U.S. Wheat and Barley Scab Initiative Forum and consisted of various studies that compared the efficacy of fungicide treatments on wheat over the course of 19 years. Overall, the results show that reducing DON contamination up to 45% is difficult to achieve solely by growing less susceptible wheat varieties, and that successful management requires multiple control strategies incorporating fungicides, wheat varieties, etc.

The results also showed that some fungicides exhibited better control than others. Applying some fungicides after flowering was also found to demonstrated equivalent control of the disease when completed to their application at flowering.  However, applying fungicides before flowering exhibited significantly less DON control.

In summary, FHB is not an easy disease to manage as its control requires several different factors. For more information and detailed findings, click here.
