Abstract
Scab or "head blight" of wheat has been known in Minnesota
for more than twenty years. The disease seems to have attracted
little attention, however, until about 1915 1vhen it became suffi·ciently
prevalent, especially on Marquis wheat, to attract the attention
of growers, who sent to the experiment station a great
many diseased heads of wheat with the comment that head blight
was doing a great deal of damage. Practically every one of these
farmers said that Marquis was more severely injured than other
varieties. Whether the introduction of Marquis and its g-eneral
use was responsible for the increasing amount of scab is not definitely
known, but it is certain that the disease seems to have become
more prevalent with the general adoption of Marquis.
Altho considerable work already had been clone on the disease,
many facts concerning its general characteristics were still unknown
when the writers began their investigations. The conclitions
most favorable for its development, the plants attacked, the
distribution in the state, the amount of damage caused by the disease,
and especially the control measures were known only very
imperfectly. For this reason work on these various phases of the
problem was begun in 1915 and has been continued until the
present time. The major part of the work was completed in 1920
and little has been clone since.
