Pecan Tree Bark Peeling: Photo Request for Rust-Colored Substance Diagnosis

James: 6-year-old paper shell pecans, bark peeling with brown rust between layers.

Expert Response

Steve requested photo (review for focus first) plus:

Overall tree appearance: thinning or full canopy?
Leaf spots present?
Duration: when first noticed?

Diagnostic Value

Pecan bark issues range from normal exfoliation to serious cankers. The rust-colored material suggests possible fungal activity. Photos and canopy assessment distinguish benign from pathological.
