By Ashley Robinson Gummy stem blight (GSB), also known as black rot, is a common issue for watermelon producers in the Southeast. Didymella bryoniae, the fungus that causes GSB, favors warm and humid weather, leaving the Southeast growing region susceptible to the disease’s devastating effects. If not managed well, it can cause significant yield loss for growers. RECENT ISSUES Over …
Grafted Watermelon Seedlings Could Benefit Growers

Wildflowers Help Watermelon Pollinators
By Karla Arboleda To attract more watermelon pollinators, growers can use different types of wildflowers around their crops. That’s what Miriam Jenkins, a graduate of Clemson University’s Wildlife and Fisheries Biology program, determined from her recent study. For pollinator-dependent crops like watermelon, adding certain wildflowers to the surrounding landscape helps create a better area for pollinators to feed. Jenkins said …
USDA to Survey Fruit Growers about Chemical Use
Athens, GA (USDA/NASS) – The U.S. Department of Agriculture’s National Agricultural Statistics Service (NASS) will survey fruit growers in 11 states, including Florida, Georgia and South Carolina, for its biennial Fruit Chemical Use Survey.

More Ways to Manage Fusarium Wilt
By Karla Arboleda Five years ago, there was no solid foundation for managing fusarium wilt in watermelons. Now, researchers have identified several techniques watermelon growers can use to help combat the disease. Nicholas Dufault, associate professor of plant pathology at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS), says his research on the pathogen is leading to …
Fusarium Wilt Management in Watermelons
By Karla Arboleda Watermelons this season have suffered through the hot weather, and researchers in Jackson County, Florida, have been seeing mixed results with fusarium wilt management. Josh Freeman, University of Florida Institute of Food and Agricultural Sciences associate professor of horticultural sciences, works on how to deal with the watermelon disease. “It’s really the primary soilborne disease that growers …
New Watermelon Rootstock Proves Pest, Disease Resistant
By Karla Arboleda Southeastern watermelon growers have struggled with fusarium wilt and nematodes for decades. A new rootstock may be the light at the end of the tunnel. Carolina Strongback, a new watermelon rootstock, is resistant toward fusarium wilt and nematodes. Researchers developed the watermelon line at the U.S. Department of Agriculture’s Agricultural Research Service (ARS) and Clemson University. They …
