Melanie Lewis Ivey

.

Title / Institution: Assistant Professor, Extension Fruit Pathologist, Fresh Produce Safety Specialist, The Ohio State University-Wooster Campus

Role on Project: Key Personnel; Extension and Outreach. Participation in the project will include holding workshops for Ohio growers with the goal of increasing grower awareness and understanding of fungicide resistance development in resident fungal populations, deliver in-field demonstration trials to demonstrate the impact that alternative spray programs can have on reducing the risk of fungicide resistance, monitoring for powdery mildew resistant isolates through the use of sentinel plots, and monitoring for resistance in production vineyards across the state. In addition, the third year annual project meeting will be hosted by The Ohio State University in Cleveland Ohio.

Research/Extension/Teaching Interests: Dr. Lewis Ivey’s applied research program focuses on the development and integration of sustainable strategies for managing diseases of fruit crops and hops. Her Extension activities include the development and delivery of targeted, science-based, disease management guidelines and knowledge translation programs aimed at enhancing the health and safety of fruit crops.

Ioannis Stergiopoulos

.

Title / Institution: Associate Professor of Plant Pathology, University of California Davis

Role on Project: Key Personnel; Research. My role in this project is to oversee the genome sequencing of Erysiphe necator, assist in monitoring fungicide resistance in this pathogen through target-site mutation detection, and unravel the molecular basis of SDHI and quinoxyfen resistance in E. necator.

Research/Extension/Teaching Interests: My research focuses on the molecular genetics and genomics of plant-microbe interactions aiming on understanding two fundamental questions, (i) how fungal plant pathogens cause disease and (ii) how plants defend themselves against fungi. I also study the molecular mechanisms and evolution of fungicide resistance in phytopathogenic fungi both in the field and in a lab setting, in order to design better management strategies that will preserve the efficacy of existing and future chemistries.
