The majority (but not all) of U.S. wheat- and barley-producing states enjoyed a calm year in terms of Fusarium Head Blight incidence and severity. As always, growing season weather played an important role in disease incidence and severity, or lack thereof.
Commonly referred to as “scab,” Fusarium Head Blight, caused by the fungus Fusarium graminearum, can produce significant yield losses, as well as serious grain quality issues due to the presence of the mycotoxin known as “DON” (deoxynivalenol).
A recent survey of university small grains specialists by the U.S. Wheat & Barley Scab Initiative (USWBSI) found growers had very few problems with the disease this year in eastern states like New York, Maryland, Virginia, the Carolinas and Georgia. The exception was Pennsylvania, where central and southern wheat counties in particular incurred very serious levels of infection.
Southern states (Alabama, Mississippi, Arkansas) reported low incidence of scab this year in their wheat crops, as growing season weather was not conducive to its development
Ohio’s wheat producers suffered high scab levels in 2010.… Continue readingRead More »
