August 10th – Hot and Humid Weather is Accelerating the Disease!

 

Tamra Jackson from University of Nebraska, Doug Jardine-Kansas State are sounding the bell for growers to look at the infestation of GLS gaining and ultimately affecting yield in corn fields of Kansas/Nebraska/Iowa.

 

Dr. Jardine noted in late July, “For fields where the disease is already above the ear leaf, producers should consider using a triazole or triazole-containing fungicide, such as Quilt ® , Stratego ® , Tilt ® , Bumper ® , or Propimax ®. In fields where the disease has made less progress, strobiluron fungicides such as Headline ® or Quadris ® can work well.

 

“The most severe disease outbreaks will occur where susceptible hybrids are being grown in a corn-after-corn or no-till situation,” the plant pathologist said.
