Systemic Fungicides Enhance Gummy Stem Blight Control
Gummy stem blight control is known to cause yield loss of 30-40% if not properly managed. Researchers in key melon regions adjusted management recommendations for this disease during 2017 that growers can use to prepare for 2018.
In a media release issued by Clemson announcing their release of the 2017 guide, researchers pointed out a major change to recommendations which now emphasize the importance of systemic fungicides to gummy stem blight management. Data discussed in the release demonstrated that the use of systemic fungicides reduced disease severity and also inhibited the formation of fungal spores to a greater extent than protectant fungicides.
Per Clemson University Cooperative Extension Watermelon Spray Guide, Inspire Super® fungicide and Switch® fungicide are recommended for gummy stem blight management in a rotation program with fungicides from other FRAC groups. Inspire Super combines 2 active ingredients for broad-spectrum control of watermelon diseases via its translaminar and xylem-mobile systemic activity. Switch attacks disease pathogens at 4 different stages in the pathogen life cycle to provide long-lasting control.
