Happy 4th of July from the Crops Team!

[ISU Crop News @ISUCropNews]

It's field day season! The last two weeks @ISUExtension campus specialists and field agronomists have been busy with summer field days and in-season trainings. It's been great seeing everyone at each of these events!

There are more field days to come: https://t.co/yPs23J0tiq

Gray leaf spot and bacterial leaf streak can look similar on corn leaves, but management is different. Fungicides work against gray leaf spot, but not bacterial leaf streak.

Both diseases produce long lesions between leaf veins. Gray leaf spot lesions are rectangular with straight edges. Bacterial leaf streak lesions are tan to brown with wavy margins.

A helpful diagnostic trick: hold the leaf up to the light. Bacterial lesions often show bright yellow halos, unlike gray leaf spot.
