Wheat Diseases in Arkansas
Several serious wheat diseases occur in Arkansas.
Loose smut and glume blotch are the most consistent seedborne diseases of
wheat in the state and systemic seed treatment fungicides are commonly used to
minimize these problems.
Barley yellow dwarf virus, if transmitted by aphids in the fall, can cause
serious problems the following spring but is an erratic disease most years.
Soilborne viruses are common in northeast Arkansas and resistant varieties
are planted there for control.
Foliar diseases in the spring include leaf rust and Septoria tritici leaf
blotch. Both can cause serious yield and quality losses under the right
conditions. Growers plant resistant varieties or use a single foliar fungicide
application in the spring to control these diseases.
Stripe rust is a very fast moving, dangerous disease but only rarely affects
large areas of wheat in the state. Last year (2000) was one of those times, when
an epidemic affected more than 250,000 acres in Arkansas. Timely fungicide
applications prevented major losses, however.
In rare instances, head scab of wheat has been a major problem in Arkansas.
It has been several years since conditions favored this problem, though.
Other diseases are sporadic, isolated or minor and include powdery mildew,
downy mildew, tan spot, bacterial streak and others.
