Objective
1) Examine three different air stream speeds (maximum, minimum, and median range of the sprayer), orifice angles of 30, 60, and 78 degrees down from horizontal and nozzles that produce 'large', fine, medium, and course drop sizes to achieve maximum fungicide deposition and efficacy on small grains for control of FHB. 2) Examine the benefits of making a sequential fungicide application about 7 days after the initial application. 3) Compare 'Tradition' to 'ND20448' barley. Tradition is a malt type barley cultivar that was planted on the greatest number of barley acres in North Dakota in the past year. 'ND20448' is an NDSU line being considered for replacement of 'Tradition'. One of 'ND20448' unique qualities is that it has been shown to accumulate 1/3 less deoxynivalenol (DON) in the seed than 'Tradition' and other 6-row type cultivars. 4) Support research efforts by the major public hard red spring wheat programs in the upper Great Plains in developing lines that reduce the effects from FHB. 5) Provide field evaluations of biological control agents or biologically based products for control of FHB and DON on different market classes of wheat and barley in different environments using standardized methods.
