Research Interests

The turfgrass industry is a billion dollar business in Pennsylvania. Golf courses, landscapes, athletic fields, business and residential lawns, and sod production all represent significant components of the turf industry. Maintaining high quality turf is one of the top priorities of the turf industry. Diseases such as gray leaf spot, anthracnose basal rot, dollar spot, brown patch, and Pythium foliar blights pose significant challenges for the turfgrass industry in producing and maintaining a high quality turf.

My research program involves management of gray leaf spot of perennial ryegrass turf caused by Magnaporthe oryzae, through applications of the principles of plant disease epidemiology and biology of the pathogen. The epidemiological research focuses on the influence of environmental conditions on development of gray leaf spot under various turfgrass management practices. Research on biology of the pathogen entails characterization of the population structure of M. oryzae in various geographic regions of the United States. Additionally, forecasting the outbreaks of dollar spot epidemic through an innovative approach to detection and quantification of pathogen biomass in root and thatch zone, using procedures in molecular biology, is a component of my research in epidemiology.

A second component of my research program encompasses induced systemic resistance in plants through integration of biological and chemical plant defense activators as part of an integrated management for gray leaf spot and dollar spot diseases. Fungicidal control of various foliar and root diseases of turfgrass is also a significant part of my research program. I maintain a collaborative research with the fungicide industry for development of a sustainable disease management program as part of an integrated turfgrass disease management strategy.

My outreach program involves disease diagnostic services and management recommendations to the turfgrass industry in Pennsylvania.

Extension Activities and Interests

My outreach program involves disease diagnostic services and management recommendations to the turfgrass industry in Pennsylvania. In addition to the resident courses at Penn State in turfgrass diseases, I also offer this online course, PPEM 412 "Turfgrass Disease Management," as part of Penn State's Distance Education program.

Course Overview

This course will provide an introduction to concepts of disease processes in plants and biology of plant pathogens, principles of turfgrass disease diagnosis based on symptom development, recognition of signs and microscopic structures of the pathogens, environmental and cultural management factors influencing disease development, significance of pathogen life cycle in disease epidemic development, and integrated turfgrass disease management practices. Disease of various turf types for golf courses, residential lawns, landscapes, and athletic fields will be discussed. Disease topics will include diseases that commonly occur in winter, diseases that develop in spring and persist into summer, and diseases that initiate in summer and remain active until late fall in most regions of North America. A number of non-infectious disorders of turf caused by extreme environmental conditions and improper cultural practices will also be discussed.

Course Objectives

Upon completion of the course students will be able to:

  • Understand the basic concepts of plant disease caused by microorganisms.
  • Understand the nature of the cause of turfgrass diseases, influence of the environmental conditions on disease development, and disease management strategies.
  • Develop the skill in diagnosis and management of turfgrass diseases.

Academic Integrity

Academic integrity is the pursuit of scholarly activity in an open, honest and responsible manner. Academic integrity is a basic guiding principle for all academic activity at The Pennsylvania State University, and all members of the University community are expected to act in accordance with this principle. Consistent with this expectation, students should act with personal integrity, respect other students' dignity, rights, and property, and help create and maintain an environment in which all can succeed through the fruits of their efforts. Academic integrity includes a commitment not to engage in or tolerate acts of falsification, misrepresentation or deception. Such acts of dishonesty violate the fundamental ethical principles of the University community and compromise the worth of work completed by others (see Faculty Senate Policy 49-20, G-9 Procedures and the Code of Conduct).

Read the Academic Integrity Guidelines for the College of Agricultural Sciences

A lack of knowledge or understanding of the University's Academic Integrity policy and the types of actions it prohibits and/or requires does not excuse one from complying with the policy. Penn State and the College of Agricultural Sciences take violations of academic integrity very seriously. Faculty, alumni, staff and fellow students expect each student to uphold the University's standards of academic integrity both inside and outside of the classroom.
