Cheryl Trueman

Vegetable Pathology & Entomology
College Research Professor

Education:

M.Sc. – Plant Pathology - University of Guelph
B.Sc. (Agr.) – University of Guelph

Research Interests:

My research interests focus on integrated management of insect and disease pests of vegetable crops 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 reduce the development of pesticide resistance.

Recent or current projects include:

  • Disinfectants and other treatments as preventative tools for bacterial spot in tomato transplants
  • Optimizing management of Cercospora leaf spot of sugarbeet in the wake of pyraclostrobin fungicide resistance
  • Management and identification of bacterial spot on pumpkins and squash
  • Fungicide spray programs and monitoring for cucurbit downy mildew
  • Management of belly rot in pickling cucumbers

Teaching Responsibilities:

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

Current courses include:

Past courses include:

  • Insect & Disease Management
  • Vegetable Crop Pest Management
  • Plant Health & the Environment
  • Organic Production
