Cercospora Leaf Blight Control Necessary for Soybeans

Cercospora leaf blight is the number one cause of yield loss in soybeans among leaf diseases in the U.S. BASF Technical Marketing Manager Albre Brown says it was once an issue mostly for southern farmers, but it has expanded north. “Because the past few years we’ve seen warmer temperatures, soybeans in more northern geographies are starting to show a greater symptom progression and onset of this disease in those geographies.” Brown says it all starts with prevention. “The pathogen survives in infected residue. If you’ve had the pathogen in the past, you’ll likely see it again. Prevention can occur by using high-quality seed.
