Cool, wet weather has persisted and is forecast through 4/28. Wheat is
likely to start flowering this week in varieties that started to head out at
the end of last week in southern portions of MD and DE. Applications of
Prosaro, Proline, and Caramba can be made anywhere from the start of
flowering (roughly 50% of main tillers flowering in the field) to 5-6 days
afterwards without a loss of efficacy. Applicators should include 0.125% NIS
and apply at least 2 hours before rain for maximum effectiveness. Aerial
applications should be made at 5 gal/A and at least 15 gal/A if applying by
ground. Target 300-350 um droplet size. Nozzles angled forward 30 degrees
will improve coverage of the head. I expect flowering will continue up the
shore over the next 10-14 days. Growers should continually scout fields and
check this page for updates.
