Growing disease-free plants
The plant pathology program is focused on integrated disease
management of powdery mildew in nursery crops. Objectives of this program
include understanding the epidemiology of the disease, examining alternatives
to traditional fungicides for powdery mildew control, identifying sources of
powdery mildew resistance, and developing integrated pest management strategies
that can be used for powdery mildew disease management.
Research on the components of the integrated management system include:
determining the most practical and efficient timing of fungicide
(or alternative products) applications in the powdery mildew
controls, identification of environmentally friendly microbes that can be used
to control powdery mildew, and ascertaining the effects of commonly used
fungicides on these microbes. An additional component of the Plant
Pathology Program is the continual monitoring and identification of
Phytophthora and other pathogens with potential for economic significance
to the nursery industry. The significance of this research program will
be a reduction in the amount of chemical pesticides released into the
environment and promotion of a sustainable disease management system for small
and large scale production systems.
