ENTOMOLOGY PRIORITIES

Following a three-year virtual hiatus due to the COVID-19 global pandemic, Agriculture and Agri-Food Canada’s Pest Management Centre (AAFCPMC) held its 21st annual national pest management priority setting workshop in a much-anticipated return to an in-person format in Gatineau, Quebec from March 21 – 23. The exercise was broken into three workshops, one per day, focusing on entomology, pathology and weed science over the course of the three days.

The meetings brought together a wide range of participants from across Canada, the United States, and other international partners including Brazil and the Netherlands. Participants included university and federal researchers, crop extension specialists, private consultants, provincial specialists, provincial minor use coordinators (PMUCs), registrant representatives, Pest Management Regulatory Agency (PMRA) and AAFC-PMC staff, growers and grower organization representatives.

The meetings were held to review the top priorities identified by each of the provinces’ horticultural and ornamental crop industries to establish the top national priorities for the minor crops sector. Priorities which were selected in the final ‘A’ round will guide AAFCPMC’s field research program as research projects in the 2024 season and eventually support future minor use label expansion submissions sent to PMRA once complete. The goal of the workshops was to elevate 35 ‘A’ priorities for capacity analysis consideration – eight mainstream and two organic projects per discipline, plus five regional
