Uniform Trial on Integrated management of FHB: Kentucky

Grants and Contracts Details


Using foliar fungicides or disease resistance alone, have not provided acceptable FHB and DON control results in many situations. The best available fungicides cUlTently only provide for FHBIDON suppression (~40-50% disease control) and highly FHB-resistant wheat varieties are currently unavailable. Conceptually, integrated control would maximize the strengths of specific disease control methods, while minimizing their weaknesses. The result should be more complete FHBIDON control. Integrated pest management (IPM) methods have been around for many years in a variety of pest-crop systems. However, until recently, insufficient information existed for developing an integrated FHB/DON control program. Work funded by the USWBSI since 1998 has resulted in the identification of fungicides and moderately resistant wheat varieties which can be used to develop an integrated approach to FHBIDON control. Thus, a National Uniform Trial on Integrated Control of FHB has been initiated. The objectives of this trial are to 1) evaluate the benefits of combining host resistance (one susceptible and two resistant varieties) and fungicides (non-treated vs. Prosaro-treated) for FHBIDON management; and 2) generate data aimed at increasing grower adoption of integrated FHB management strategies. The strategy is to decrease the overall risk ofFHB epidemics in the U.S. through enhanced grower adoption of integrated FHB/DON management programs. In addition, disease and weather data will be given to the coordinator of the FHB Prediction Tool with the aim of increasing the reliability and accuracy of the tool. Once refined, this FHB Prediction Tool will be used by advanced wheat producers to determine if and when it is appropriate to apply a fungicide. Knowing when to deploy a pesticide, or not, is part and parcel of any integrated pest control program. Kentucky will participate in a multi-state, multi-year study to evaluate the benefits of combining host resistance and fungicides for FHB/DON management. As part of a Uniform Trial, Kentucky will conduct two tests, both located at the Spindletop Research Farm in Lexington, KY.
