Project Title 1 - Greenhouse Studies of DON in Wheat as Influenced by Environment and F.g. Isolate: Continue to gather data on differential effects of moisture duration, growth stage at inoculation, and Fusarium isolate on FHB and DON development in susceptible and moderately resistant hard red spring wheat and durum cultivars, in controlled greenhouse inoculation experiments. Project Title 2 - Uniform Evaluation of Fungicides for FHB Control in Multiple ND Grain Classes: North Dakota produces three spring grain classes that often are affected by Fusarium head blight. Project Title 3 - Integrated Management Studies for the Reduction of FHB and DON in Multiple Grain Classes, ND: Four investigators in ND will look at two to three management strategies for reducing FHB and DON on multiple grain classes. The four investigators will look at these four crops in different environments across the state.

Project Title 1: Test 4 inoculation timings, 3 moisture duration regimens, and two to three F. graminearum isolates on two grain classes and two cultivars of each grain class to determine effects on FHB, DON, and DON derivatives. To determine if there are interactions between grain class or susceptibility of cultivar and moisture duration, growth stage and/or isolate. Project Title 2: Fungicide treatments agreed upon by the Uniform Fungicide Trial Coordinating committee will be evaluated on three spring grain classes (hard red spring wheat, durum wheat, and spring barley) at two environmentally unique locations in North Dakota – Carrington in the central district and Langdon in the north east district. Fungicide evaluation is needed on all three crops because: ND leads the nation in production of all three; FHB susceptibility varies among these three crops; and fungicide response varies slightly among these three crops to individual chemistries or combinations of chemistries. Multiple locations generally help guarantee success in getting useful information, too, as one or more locations generally have adequate to excellent levels of FHB for successful evaluation and separation of treatments. ND has provided considerable useful information to the Initiative, to producers, and to the fungicide industry from these trials, leading to improved fungicide use and fungicide registrations. Continued studies are warranted because of several reasons: Some experimental products are being developed by the crop protection industry that may have different modes of action than the standard triazoles, important because of resistance issues; some combinations of products may work more effectively than a single component; data across regions and grain classes verifies efficacy across multiple environments; continued data collection leads to new registrations; we don’t want this area to stagnate. Project Title 3: The four investigators, grain class; location of study, and strategies that will be studied\to study, and grain class(es) proposed are: 1. Marcia McMullen, Professor and Plant Pathologist: hard red spring wheat, Fargo, ND in EC region; 3 strategies: rotation, variety, fungicide. 2. Stephen Neate, Professor and Plant Pathologist: spring barley, Fargo, ND in EC region; 3 strategies: rotation, variety, fungicide. 3. Joel Ransom, Assistant Professor and Agronomist: winter wheat and spring wheat, Lisbon, ND in SE region, Prosper, ND, EC region; 2 strategies: variety and fungicide strategies. 4. Scott Halley, Research Associate and MS in Soil Science, PhD student in Plant Pathology: spring barley and durum wheat, Langdon, ND in NE region; 3 strategies with both barley and durum: rotation, variety, and fungicide.
