Lesion
Nematode - Pratylenchus species.
Disease Problem Solver - UMN NWROC
Lesion nematodes are found world-wide. They attack the root cortex. Roots develop dark lesions and an overall brown color. Loss of the epidermis and cortex decreases root growth nutrient and water uptake. Under stress, plants yellow, become stunted, and have reduced yields.
