My research program focuses on integrating basic and applied research to develop improved management strategies for fruit diseases of concern to New York producers. In recent years, research endeavors in the form of plant biotechnology have made considerable contributions to the management of fruit diseases. However, efforts are still needed to improve the concepts and products of basic research so they may be more readily applied to solve disease problems. My applied research endeavors have focused on understanding the prevalence, development, selection, and mechanisms of practical antimicrobial resistance to both antibiotics and fungicides in populations of fruit pathogens. Hence, although much of my research is concerned with applied aspects of fruit diseases, a portion of my research program will be dedicated to conducting basic research in the hope of developing products with potentially broad or far-reaching applications.

Currently, my appointment is 20% extension, 30% Teaching, and 50% research. Because of this split, I endeavor to interweave my research program goals with those of my extension and teaching programs such that my research endeavors lead to stakeholder-relevant extension deliverables and illustrations of real world teachable moments. In turn, I allow my student, grower stakeholder needs, extension concerns to guide my research efforts. Therefore, my research, teaching, and extension efforts focus on applied disease management for NY crops where accomplished have impacts and can be realized in short time frames.

To address both applied and basic research philosophies, and both research, teaching, and extension aspects of my appointment, I have established the following goals:

1. Investigate the biology and management of fungal and bacterial diseases of apple, stone fruit, and small fruit using cultural, chemical, biorational, and organic approaches
2. Understand the biology and management of single-site fungicide resistance and antibiotic resistance in pathogen populations responsible for diseases of apples, stone fruit, strawberries
3. Develop precision agriculture forecasting systems for plant disease.

My specific research objectives are to:

1. Understand cryptic infections of bud wood by the fire blight pathogen Erwinia amylovora and the prevalence and mechanisms of antibiotic resistance in regional populations of E. amylovora
2. Manage diseases of apples, stone fruit, and bush berries using chemical, cultural, organic, and biorational approaches
3. Understand the prevalence, mechanisms, and potential to manage practical resistance in populations of Monilinia spp., the causal agents of brown rot, shoot blight, and blossom blight of stone fruit
4. Investigate the persistence, prevalence, mechanisms, and factors resulting in the development and selection for practical resistance in populations of Venturia inaequalis, the causal agent of apple scab.
