[Fhb-update_ma] FHB Update from PA, 05/16/11

[FHB Updates - Mid Atlantic SWW Region]

Scattered areas within Pennsylvania are now at “Medium” risk for the development of scab in wheat that is currently flowering.  Our 7-day weather forecast includes a stretch of wet, mild weather that is conducive to the production and spread of spores.  As the week progresses, many areas of the state will likely reach the “High” level for risk.  Be prepared to spray a fungicide on fields that are at medium to high risk at flowering.  Recommended products include Prosaro at 6.5 fl oz/A or Caramba at 14 fl oz/A.  It is advisable to allow a minimum of 3-4 hours for drying and absorption of the product, although rainfast times for these products are not known.  Remember, sprays applied PRIOR to flowering will NOT provide significant suppression of scab or toxin production.
