Symptoms: a thin, longitudinal scar extends from the stem scar to the blossom end. Occassionally, an open hole to the locule forms. The defect occurs when the flower anthers fuse to the developing fruit’s ovary wall and happens most commonly when fruit set takes place in cool weather.

Glyphosate injury
