Management Of Turfgrass Diseases

This third edition of Management of Turfgrass Disease is completely revised and updated to provide the latest information on maintaining a healthy turf and identifying and treating turf diseases. Written by a leading international lecturer on turf grasses, the book’s focus is on prevention as it lays out specific strategies you can follow to stop disease from occurring in the first place. The book also addresses cultural, genetic, biological, and chemical approaches to turf management and provides practical solutions to everyday problems. You'll learn about cool and warm season grasses, growing conditions, new diseases, symptoms, and identification and management techniques. Valuable tips on irrigation, fertilization, and grass culture are included, as are 72 full-color photographs and more than 100 figures.

J. M. VARGAS Jr. is Professor of Plant Pathology at Michigan State University, where he has been involved in teaching, research, and extension for the past thirty-five years. He has published more than 200 articles on turfgrass diseases and related subjects and has given presentations at conferences throughout the world.
