SYNOPSIS

Corn and soybeans are approaching the R5 growth stage. As I type this, we are finally getting a significant amount of rain. Dryer weather, hybrid resistance, and fungicide have kept diseases like gray leaf spot and tar spot at bay in corn. But Goss’ wilt and Northern Corn Leaf blight have just started to show up. Soybeans are loving the rain and could have potential to yield if diseases stay away. One plant was found that had stem canker.
