[Fhb-update_cgp] FHB Update from NE, 05/26/11

[FHB Update - Central GP, Hard Winter Wheat]

Today, May 26, 2011, the National Fusarium Head Blight Risk Assessment Tool elevated the risk of scab to high in an area in southeast Nebraska.  Scab risk is moderate in parts of eastern, south central, southwest, and north central Nebraska.  Significant rainfall during the second half of last week and the first half of this week has contributed to the elevated risk of scab.  It is recommended that a fungicide be applied at early flowering to suppress scab.  The fungicides Prosaro and Caramba are good in suppressing scab and very good to excellent in controlling foliar diseases.  If foliar disease pressure is low and the flag and flag -1 leaves are free of disease, delay a fungicide application until early flowering and then apply a fungicide that will both suppress scab and provide protection against foliar diseases.
