There is a new threat Florida blueberry growers should be wary of: bacterial wilt. In a memo sent to members of the Florida Blueberry Growers Association, President Dudley Calfee strongly advised growers to scout fields thoroughly for this “new and dangerous pathogen.”

Five years ago, a North Carolina State University-led specialty crop project helped several U.S. growers use grafted tomato plants to return land plagued by bacterial wilt to production. The project paired needy growers with companies such as Ontario Plant Propagators that supplied grafted plants. Now NC State researchers are leading a new project that promises to find ways that grafted plants can give growers more choices to manage diseases and add value to their cucurbit and tomato crops.

“I’m not an evangelist for grafting, but I can make a field of tomatoes whole by switching from non-grafted transplants to grafted plants.
