New webcast explores migration research of zebra chip-carrying potato psyllids

Potato growers in the US looking to reduce the likelihood of a zebra chip disease outbreak have been forced to rely on calendar-based insecticide applications due to the unpredictable arrival of disease-carrying potato psyllids. Providing information about vector migration and overwintering habits is a new educational presentation from the Plant Management Network titled “What Is the Source of Potato Psyllids Colonizing Potato Fields in the Pacific Northwest?” now available in the Focus on Potato resource for growers, crop consultants, and Extension agents. The webcast, developed by David Horton, research entomologist at USDA’s Agricultural Research Service, provides possible reasons why psyllids have become more prevalent in the Pacific Northwest and discusses recorded zebra chip outbreaks and potato psyllid biology, possible non-crop host plants allowing overwintering, and current research investigating migration habits. Visit the Focus on Potato webcast resource.
