FHB Update from IL, 04/26/19

Some of the wheat that is furthest along in S IL will be approaching heading within the next 7-10 days. Temperatures will remain cool to moderate, with chances of rain over this period. Remember that fungicide applications targeting FHB should be made between the start of flowering (FGS 10.5.1) through 5-6 days post flowering. This timing has been the most consistant for reducing both FHB symptoms and DON. Reccomended products include PRosaro, Caramba, and Miravis Ace. Avoid products containing QoI's (FRAC group 11) after flag leaf emergence as these may increase DON levels in some instances.
