Wheat growers in Maryland have so far been fortunate this year for having low disease pressure from leaf rust, powdery mildew and even scab!! In the south (Eastern shore), wheat is flowering currently. With consistently warmer temperatures now, a few incidences of leaf diseases are being observed. Triazole fungicides: Prosaro/ Caramba/ Proline that are the scab fungicides should provide control against these as well. Strobilurin containing fungicides should not be sprayed at this stage, as they may lead to DON accumulation in grains. Up in the north, flag leaves are emerging. No diseases being seen so far here as well. Growers should keep an eye on the FHB risk, as crop heads and flowers here in coming weeks.
