Quantify the value of a FHB control program that integrates tolerant cultivars, fungicides, crop management and crop rotation in spring and winter wheat in North Dakota.
Approach: Establish a series of experiments in four locations in south eastern and north central North Dakota to look at the interaction of fungicide and host plant resistance on overall FHB control in spring and winter wheat to determine if there is value in growing a FHB-tolerant cultivar if fungicide is applied. Examine the effect of plant density on the effectiveness of fungicide in controlling FHB in spring wheat to determine if crop management can improve fungicide efficacy. Use on-farm monitoring to quantify the effect of crop rotation on the development of FHB and its control using genetic resistance and/or fungicides.
