Most counties in the southern region of PA are now at âHighâ to âMediumâ risk for the development of scab in wheat and barley that is currently flowering. Our current weather forecast includes a few more days of wet, mild weather that is conducive to the production and spread of spores, and possibly more next week. Be prepared to spray a fungicide on fields that are at medium to high risk at flowering. Caramba, Proline and Prosaro are effective on scab and give control of most leaf diseases and glume blotch. Remember, sprays applied PRIOR to flowering will NOT provide significant suppression of scab or toxin production. Also, the labels of these products do not allow spraying after mid-flowering, and there is a 30-day to harvest restriction.
