Barley leaf stripe, a seedborne disease caused by Drechslera graminea, has become a serious problem in the absence of an effective seed treatment. For this reason, field trials were conducted during three consecutive harvest years (19821984) to identify a suitable seed treatment for control of barley leaf stripe. Several fungicides tested provided a high level of disease control. Three of these, imazalil, CGA-64251, and iprodione, gave nearly complete control of barley stripe without phytotoxicity.
