Timing sprays for control of Septoria and suppression of FHB should focus on heading. It is still early enough that perithecia of the scab fungus could develop in infected residues present in wheat and barley fields. The recent rains will facilitate their development, particularly if temperatures remain cool and rains persist. Of equal concern, and maybe even greater concern, is the potential for Septoria diseases to develop in wheat. The development of Septoria will be favored by recent rains and past experience suggest that even fields that have been rotated to other crops can develop damaging levels of Septoria if rains continue.
Wheat stands, in general, are good and yield expectations remain high.
Rains have removed drought limiting concerns. Price and LDP program options are favorable for optimizing yields and this should include controlling diseases. Septoria can be effectively controlled with 4 oz. In the case of FHB, Folicur may be a better choice than Tilt. If leaf rust or powdery mildew are present, Tilt may perform better than Folicur.
