Resources on Fungicides for FHB
The U.S. Wheat and Barley Scab Initiative’s (USWBSI) recent Scabinar, focused on fungicides for FHB. The content of the webinar included best practices for application and use, as well as efficacy information and historical context. Whether or not you attended, here are some key messages:
Pick your product
- Choose a fungicide with care. Not all fungicides registered on small grain crops are effective in managing FHB. See the Fungicide Efficacy Guide for Control of Wheat Diseases on the Crop Protection Network to help pick the best fungicide options for managing FHB.
- USWBSI researchers are concerned about fungicide resistance and research is ongoing to monitor Fusarium graminearum populations.
Plan your application
- Applying a fungicide twice for FHB management? Results from field research trials funded by the USWBSI have shown that additional reduction in FHB and DON can occur with two treatment programs. More research is needed to better understand the circumstances in which this practice would be economical. Also, it is important to be mindful of product label restrictions that might not always allow a two-treatment application in some instances.
- Prioritize product and timing when doing your ground application—these have a greater influence than equipment features like nozzle height and droplet size.
- Time it right for maximum DON reduction. Fungicide timing postcards with images are available to print on our Communicators' Tool Kit.
