Understanding the biology of the causal organisms of disease is crucial for making informed decisions regarding disease management. It is important that growers understand the nature of infections by pathogens during periods of maximum tissue susceptibility, so that sprays are applied in a timely manner. The influence of environment is equally important, and predictive computer models, may allow further fine-tuning of fungicide application timing, especially if used in conjunction with reliable weather forecasts. Alternatives to chemical control methods for disease control are also necessary to provide a truly integrated approach to fungal disease control.

Research Projects:
Integrated management of grapevine powdery mildew (Uncinula necator)
Impact of powdery mildew on quality parameters of grape juice and wine
Epidemiology of blossom and fruit infections of peach by Monilinia fructicola
Strategies for fungicide resistance management for apple scab (Venturia inaequalis) in Ontario
Reduced pesticide use and improved control of grapevine fungal diseases through trellis design, canopy management and improved spray application using vine/row volume
Development of rapid diagnostic techniques for identification of strawberry anthracnose. (Colletotrichum spp.)
