Abstract
Gummy stem blight (GSB) is a major disease of many cucurbits, including watermelon, cantaloupe, cucumber, pumpkin, squash, muskmelon, and other melons. The disease is also known as black rot due to its characteristic appearance on infected fruits. This revised 8-page fact sheet discusses the symptoms, causal agents and disease spread, and fungicides labeled for use in Florida. Written by Mason Newark, Mathews L. Paret, Nicholas S. Dufault, and Joshua H. Freeman, and published by the UF Plant Pathology Department, August 2014.
