Area of Interest:
The ecology and management of fungal diseases of vegetable crops and citrus in Arizona.
Research Goals:
My research program primarily is focused on developing new or enhancing current management strategies for the economically important fungal diseases of vegetable crops and citrus in Arizona. The integrated use of biological, chemical and cultural disease management approaches are being developed or refined to combat the following vegetable and citrus diseases: Sclerotinia leaf drop of lettuce, downy mildew of broccoli and lettuce, powdery mildew of lettuce and melons, Phytophthora stem and root rot of chile pepper, Phytophthora root rot and gummosis of citrus and brown heartwood rot of lemon trees.
