FHB Update from IL, 05/09/18

Storms are pushing through today (5.9.18) which may increase FHB risk in some areas. Early wheat has headed in some parts of the state and will likely start flowering by the end of the week. Caramba, Prosaro, and Proline can be applied from the start of flowering (50% of main tillers starting to flower) through about a week after this point without a loss in efficacy. Other active ingredients such as tebuconazole (Folicur etc) and propiconazole (Tilt etc) can be used but are not very efficacious for FHB. Do not apply products containing a strobilurim (QOI: FRAC group 11) to heads as these active ingredients have been demonstrated to increase vomitoxin in our replicated trials.
