Botany and Plant Pathology 

  • Professor

765.494.0363
Lilly Hall Room 1-238

Background

    Ph.D. (Plant Pathology), University of Florida, 1977
    M.S. (Microbiology / virology), Florida Atlantic University, 1971
    B.S. (Biological Sciences), Florida Atlantic University, 1969

Martyn joined the Department of Botany and Plant Pathology (BTNY) at Purdue University in 1997 after serving 20 years on the faculty of Texas A&M University. From 1997 to 2005 he served as professor and BTNY department head. From 2005 to 2007 he was Director of the Center for Crop Biosecurity and Invasive Plant Pests. He has published over 100 scientific articles, including journal articles, book chapters and reviews and technical publications. He has served The American Phytopathological Society (APS) in numerous capacities, including as vice president, president-elect and president (2005-08); Councilor of the North Central Division (2003-05); vice president and president of the Southern Division (1995-96); Plant Disease Editorial Board (1984-88); and on numerous other committees and boards. He currently serves on several advisory committees related to agricultural biosecurity including the USDA National Plant Disease Recovery System and the APS Emerging Pathogens Committee. He has received several career awards including the Distinguished Achievement Award in Teaching (Texas A&M), the Cooperative Extension Team Award (Purdue), and the Distinguished Service Award (Indiana Crop Improvement Association).

Research

Over the years my research focused on soilborne diseases of watermelon and muskmelon, primarily Fusarium wilts and late-season vine declines. Interests have been in the area of molecular evolution of pathogenic formae speciales and races of Fusarium oxysporum and the biology and management of Monosporascus root rot/vine decline. This latter disease has become a limiting factor in melon production around the world in the last 25 years. Due to administrative responsibilities as department head and center director, my active research program was shut down and I no longer accept graduate students or post doctoral fellows into my program.

Teaching

Martyn teaches two courses in plant pathology. The first is Introductory Plant Pathology (BTNY 30100). This 3-hr lecture / laboratory class is offered each fall semester and is a general overview course on the principles of plant pathology and the biology of plant pathogens. Martyn also teaches The Principles of Plant Disease Management (BTNY 53500) each spring semester. This is a 3-hr lecture course intended for students majoring in plant pathology, crop protection or related discipline. The course focuses on how plant disease spread and the seven principles of plant disease management.
