The Fusarium Head blight risk tool indicates low scab pressure for the state of Arkansas on susceptible varieties as of April 8th.  Most wheat should be flowering in the south and central part of the state or will be by the end of this week.  Growers should be mindful that the tool provides regional guidance, and this alone does not guarantee that you will not see some level of scab in your fields.  The information provided by this tool should be used in addition to local experience with your fields and previous knowledge of varieties grown.  If a fungicide application for scab is made, optimal timing is early flowering to 5 days after the start of flowering with a product labelled for scab suppression.  Please see the current Arkansas Plant Disease Control Products Guide – MP154 ( for fungicide options for scab.  Additionally, earlier fungicide applications were made to some fields for stripe rust. These applications should not be
  considered preventative for scab.
