Thomas Forge, Ph.D.

Research Scientist

Applied Soil Ecology / Nematology

Current research and/or projects

General area of research is applied soil ecology, with an emphasis on: (1) Ecology and management of plant-parasitic nematodes; and (2) Integrated root health management for perennial horticulture crops.

Current projects:

  • Impacts of plant-parasitic nematodes on perennial fruit production in British Columbia
  • Comparative tolerance and resistance of new cherry and apple rootstocks to plant-parasitic nematodes
  • Identification and distribution of plant-parasitic nematode species of concern to agriculture in western Canada
  • Pre-plant soil and water management practices to suppress plant-parasitic nematodes and improve replant establishment of perennial fruit crops
  • Interactive influences of organic amendments, mulches and alternative irrigation practices on nematode population dynamics in orchards and vineyards

Education and awards

  • Ph.D. (Plant Pathology), University of Wisconsin-Madison
  • B.Sc. (Biology), Kansas State University
