June was hot and wet with temperatures consistently near 90˚ F and many areas getting close to 10 inches of rain, but it followed a May that was hot and dry with temperatures up to 100˚ F. That meant less gummy stem blight.
Watermelon producers in South Georgia who were impacted by excessive rainfall in February and early March could see their planting window delayed.

Gummy stem blight (GSB) and fusarium wilt (FW) can be common problems for watermelon producers in the Southeast. These two diseases are caused by fungal pathogens from the same taxonomic subphylum, but that is where the similarities end.
