***** Disease Update - 12 September ***** Two outbreaks to report.... one near Tifton in southern Georgia. Kenny Seabold informs us of an outbreak on watermelon in a one-acre test plot. First observed in late August, disease severity increased significantly about 10 days after the last application of Ridomil. Irrigation and early-morning dews have provided favorable conditions for DM. Our thanks also to Margaret McGrath in New York. She states that downy mildew was observed on September 9th in Suffolk County, near the town of Riverhead. This is a non-serious infection of pumpkin and winter squash in a 0.2-acre plot.
FORECAST SUMMARY - Thursday, September 12
*** Dry over most areas Thursday and Friday. However, the effects from a tropical system in the Gulf and an approaching cold front will bring rainy weather to the Eastern Seaboard Saturday and Sunday *** A tropical depression in the eastern Gulf will bring showers to FL today. The rest of the East will be dry courtesy of high pressure centered in the mid-Atlantic states. The future behavior of the tropical depression is uncertain..... but it is expected to move slowly north or northwest before it heads to the northeast late Friday or Saturday.... ahead of an approaching cold front. Showery weather in FL will spread to the Southeast on Friday, mid-Atlantic and mountains on Saturday, and farther north on Sunday.
Thursday.... HIGH RISK for central and northern FL, Moderate Risk for southwest GA. Low Risk otherwise.
Friday.... HIGH RISK for central and northern FL, southern and western GA, and eastern AL. Moderate Risk for southern SC. Low Risk elsewhere.
Saturday and Sunday... trajectories will be moving north and northeast from most areas. Favorable weather will spread into the mid-Atlantic states on Saturday, Northeast on Sunday. Mixed conditions are expected in the southern GA and FL areas by Sunday in the wake of the tropical moisture.
