FHB Update from DE, 05/03/14

Most of Delaware and parts of Maryland received a substantial amount of rain this past week, but temperatures remain cool. Wheat across Delaware is between Feekes 6 and 8, and I expect significant growth progress based on increasing temperatures and light showers ahead. Some foliar diseases are popping up, but overall levels are low.

Barley is starting to come out of boot in many parts of the state. I do not currently recommend an application for FHB management but if you choose to make an application ensure that at least 35% of your main tillers have emerged fully from the boot. Those of you double cropping to lima beans should be aware of label restrictions to Prosaro and Caramba. Proline is a good alternative in these instances.
