Cool, wet conditions create good environment for crops, diseases

From Delta Farm Press

This has been one of the coolest summers in recent memory for residents of the South and Southeast. Instead of breaking into a sweat moments after you walk outside, farmers and others who work outdoors have been able to stay reasonably calm, cool and collected.

Unfortunately, the same can also be used to describe foliar diseases that can infect corn, cotton, rice and soybeans. Some have flourished while others – which tend to do better in hotter, dryer weather – have languished.

“In soybeans in Tennessee, we are getting reports of frogeye leaf spot in the field in susceptible varieties,” says Heather Young-Kelly, Extension plant pathologist with the University of Tennessee. “In my own research plots, I’m seeing it where I expect it. I have seen that it’s a little delayed in its development due to the low relative humidity and the cooler temperatures.”

Dr. Kelly was one of several university speakers who participated in the Asgrow/DeKalb agAcademy Field Day in Union City, Tenn. About 200 farmers traveled to the Aug. 7 event from Kentucky, Missouri and Tennessee.

The cooler temperatures and rains are also the right conditions for SDS or sudden death syndrome in soybeans along with other diseases that have been showing up in corn, cotton and rice in 2014.
