Question:

Good morning. Here’s my annual late leaf spot text. Hope you’re doing well.

Jordan:

Hope you are as well. My impression is that this is chemical burn. We will begin seeing leaf spot but this looks like burn.

Follow Up:

With the underside spores?

Jordan:

I decided to send these to David L. The whole canopy look seems to be chemical burn. The individual spots could be leaf spot disease. David?

Langston:

Based on the sporulation I see on the undersides of the leaves, its late leaf spot.

Follow Up:

This field got its third spray within the last five days. Which was Bravo + Convoy. He did not have worm insecticide in The mix. I’ll discuss adding Proline and/or sulfur with that trip.

Jordan:

With our weather, I would suggest a tighter interval too. Error on early on each of the following sprays.
