DELMARVA — An Extreme Heat Warning is in effect across the Delmarva Peninsula from Tuesday, June 30 through July 4, covering a multi-day stretch of dangerous conditions over the Independence Day holiday weekend. The National Weather Service out of Mount Holly issued the warning early Tuesday morning. Farmers are advised to schedule their heaviest field work before midday and ensure livestock have adequate shade, water, and ventilation.
Crop Scouting
A Bayer agronomist is urging corn growers to scout their fields immediately. Doug George says June’s warm, humid weather pattern mirrors conditions from 2021 — a year that brought serious tar spot damage to corn across the region. The fungal disease thrives under heat and humidity, and George says early scouting is critical to catching it before it spreads.
Conservation
ShoreRivers has secured more than $3 million in grant funding from Maryland’s Chesapeake and Atlantic Coastal Bays Trust Fund. The project targets a Cecil County farm along Black Duck Creek, restoring 3 degraded stream segments totaling 3,770 feet. When complete, the project is expected to remove more than 4,138 pounds of nitrogen from the watershed each year.
Markets
Monday’s grain markets closed soft. July corn settled at $4.02/bu. July soybeans closed at $11.08¾. July Chicago wheat settled at $5.69½. At Laurel Grain Company in Laurel, Delaware, December corn is bid at $4.47/bu.
Forecast
Highs are expected near 90°F Tuesday under mostly sunny skies, with south winds to 10 mph. Wednesday temperatures surge to 95°F with sunny conditions. No rain is in the forecast.
