Research and/or project statements

  • The greenhouse entomology team at the Harrow Research and Development Centre focuses on the development of integrated pest management programs for the Canadian greenhouse horticultural industry. 
  • Our work entails the discovery and validation of novel biological control and reduced risk agents used to suppress pests of greenhouse crops, as well as the development of new tools and technologies to improve pest management.
  • This research program has as its goal to optimize the competitiveness and sustainability of Canada's greenhouse vegetable production sector.
