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.
