FORECAST SUMMARY: Thursday, May 15:
***** Disease Update - 15 May *** First report of downy mildew from Georgia ... David Langston and Russ Hamlin have reported and confirmed an outbreak of downy mildew in far southern Georgia. Disease is active in fields of summer squash in Echols and/or Lowndes counties, near the town of Lake Park. This serious source is being added to the forecasts.
***** Disease Update - 8 May *** First report of downy mildew from South Carolina.... our thanks to Anthony Keinath.... who informs us of a non-serious outbreak of downy mildew on cantaloupe near Charleston, SC. Recent weather has been favorable. From southern Florida..... Gene McAvoy's report from southern FL states that recent favorable weather has resulted in new and/or renewed infections in many locations of southern FL. Outbreaks have also occurred in south-central FL in Desoto and Okeechobee counties. Crops most affected are pumpkin, cantaloupe, and winter squash. New source sites at Charleston, SC and Arcadia, FL will be added to account for these new infections.
***** In the Southeast.... An active weather pattern is expected through the weekend. Transport events from the various sources will be affecting the source regions and nearby areas, with no long-range threats. Mixed weather conditions will be dominant. All of FL, plus southern GA, will be at Moderate Risk every day, with the risk heightened to Strongly Moderate for northern FL and southern GA on Thursday. Disease activity near Charleston will depend on local conditions, again generally mixed with some variation in favorability Thursday and Friday.
***** In Texas.... active weather across the north and east today through Saturday as a frontal system lingers near and then moves through the state. However, southern and western sections will be sunny to partly cloudy and dry. This includes the source region in deep South Texas. Trajectories move toward other areas Thursday and Friday, but intense heat and solar exposure will squash any significant threat. Low Risk to cucurbit crops in this region for the next 4 -5 days.
