Understanding Turf Diseases

Disease outbreaks are the result of a combination of factors occurring at the same time. These factors include the presence of the pathogen, the status and vulnerability of the turf, and certain prevailing environmental conditions. The discovery component of our turf disease project is focused on describing and defining the factors that contribute to disease, thereby providing a foundation for building modern effective disease control strategies.

Fungicides are essential tools for suppressing infectious diseases and maintaining high quality turf. Research continues to identify appropriate chemical solutions for a variety of diseases and to investigate how they can be used most efficiently to reduce costs and limit chemical use.

Turf Disease Management Workshops, Seminars and Lectures

These programs are designed to address topics relevant to the work of golf course superintendents, sports turf managers, lawn care professionals, turf industry representatives, consultants, and county extension staff. They address contemporary issues in turf disease identification and control and often are offered as part of a more comprehensive program on turf management. Purdue Turfgrass Program

Turfgrass Disease Profiles

The turf disease profiles represent a series of informational bulletins that deal with important turf diseases in Indiana and the lower Midwest. These descriptions describe the nature of disease-related damage, highlight diagnostic signs and symptoms (color images are included), and discuss conditions that promote disease outbreaks. They also address various kinds of control options for professional and residential and offer specific recommendations for disease.

Turfcast

Turfcast is a computerized system that defines the connection between weather and turf disease outbreaks. The system indexes each day in terms of the risk of establishment and spread of three important diseases (dollar spot, brown patch, and Pythium blight). The program is operational from April 1 through October 31 and is accessible to all interested users on the website http://btny.agriculture.purdue.edu/turfcast.

Exploratory Activities

During the growing season, periodic field excursions are conducted to assess the current status of turf disease epidemics throughout Indiana and other parts of the Midwest. We also collect isolates of certain pathogens so that we can profile their sensitivity to common turf chemicals.
