Dr. Cheryl Trueman

Vegetable Integrated Pest Management
Assistant Professor


Ph.D. Environmental Biology – University of Guelph
M.Sc. Horticulture – University of Guelph
B.Sc. Agriculture – University of Guelph

Research Interests:

My research interests focus on integrated management of disease and insect pests of field vegetables in Ontario including tomatoes, cucumbers, pumpkins, squash, cabbage, broccoli, peppers, sugarbeets, snap beans, potatoes, and sweet corn. I am interested in applied research that can be adopted by growers in Ontario to improve pest management, reduce yield and quality losses, and delay the evolution of pesticide resistance.

Recent or current projects include:

  • Management of bacterial spot on field tomato, pumpkins, and squash: identification of pathways of transmission, host resistance on foliage and fruit, evaluation of nanoparticles and other bactericides
  • Management of Cercospora leaf spot of sugarbeet: integration of host resistance and fungicide programs, identification of alternative crop protection tools, influence of deposition aids and water volume on fungicide efficacy, improve understanding of initial inoculum sources of Cercospora beticola, fungicide insensitivity monitoring
  • Integration of host resistance and fungicides for management of cucurbit downy mildew
  • Spore trap surveillance of Phytophthora infestans to identify high-risk periods for late blight in field tomatoes

Teaching Responsibilities:

I teach in the Agriculture and Horticulture Diploma programs at Ridgetown Campus.

Current courses include:

Past courses include:

  • Insect & Disease Management
