Winter, Wheat and Insect Antifreeze
Description
During this episode of the Indiana Agronomy podcast, hosts Carl Joern and Ben Jacob discuss wheat, the weather, and whether an extreme cold snap can kill tar spot. "I'm not under the impression that cold temperatures have any impact on tar spot. It's a fungus, and I'm not aware of any published research that shows that extreme cold kills off those spores," says Joern.
Spoiler alert: Insects are resilient, and they will overwinter. It takes temperatures of -40 degrees celsius to kill off many insects that affect crop health.
