Researchers Go Toe to Toe with PCN

Although extremely rare in Canada, potato cyst nematodes (PCN) are such a serious risk to potato production and trade that the Canadian Food Inspection Agency (CFIA) has strict surveillance and quarantine protocols. When PCN was discovered in Quebec in 2006, the CFIA immediately implemented quarantine measures for the affected fields. As well, the agency took other important steps, including working with Agriculture and Agri-Food Canada (AAFC) and other stakeholders to identify research…

New Prospect for Wireworm Control

A few years ago, Todd Kabaluk was given some fuzzy wireworms. That might not sound like an auspicious gift, but Kabaluk is a research biologist in integrated pest management with Agriculture and Agri-Food Canada (AAFC). He was immediately interested. As it turned out, these fuzzy wireworms were the first step on the path toward a new possibility for controlling wireworms. Wireworms are the tough-to-control, soil-dwelling larvae of click beetles. AAFC has found…

Volunteer Potatoes: Potential Issue in 2019

Volunteer potato plants (potatoes growing from unharvested tubers) might be problematic in rotation crops during the 2019 growing season. These plants can be a competitive weed with most crops and act as a reservoir for diseases and insects. In general, winter conditions in Canada are severe enough to control most volunteers (soil temperature below -2 C or 28 F) but winter survival is dependant on tuber health, temperature, snow cover and burial…
