Spots on Peanut Leaves Peanut Notes No. 117 2025

Question:

This is what I think may be early leaf spot. Correct?

Jordan:

This is chemical burn of some kind. Not the leaf spot we control with fungicide.

*Leaf spot in our region is seldom seen until mid to late August even when fungicides are not applied. Disease starts lower in the canopy.

Spots and holes on leaves indicating chemical burn.
A hole surrounded by yellowing on an otherwise healthy leaf.
