Take-all Root Rot

M. L. Elliott and P. F. Harmon

This document discusses the root rot disease affecting warm season turfgrasses, caused by the pathogen Gaeumannomyces graminis var. graminis. The disease is triggered by high rainfall and stressed turfgrass, leading to symptoms such as yellow patches and rotted roots. Cultural controls, including proper mowing and balanced nitrogen-potassium applications, are essential for managing the disease. Preventative fungicides can be used but are less effective once symptoms appear. The document emphasizes the importance of stress prevention and provides detailed guidelines for turfgrass management to mitigate the impact of the disease. First published: July 1994.
