Barley Yellow Dwarf
Although Barley Yellow Dwarf is a significant problem in Alabama, no current oat or wheat varieties have adequate resistance to this disease. All oat and wheat varieties are susceptible.

Hessian Fly
In the 1996-97 and 1997-98 growing seasons biotype ‘L’ of hessian fly was found in Alabama. This biotype represented only a small portion of the population. The level of resistance to hessian fly as shown in the table is only valid for the biotypes other than ‘L’ since none of the current commercial varieties are resistant to this new biotype.
