Early bird may dodge verticillium woes in potatoes
Pushing a problem field to the front of the planting queue may help limit infection
Verticillium wilt is a problem for a lot of crops in Manitoba, including canola, sunflowers and alfalfa. In potatoes, the fungus Verticillium dahlia is the main cause of potato early die complex. In a 2021 interview with the Co-operator, Mario Tenuta, University of Manitoba soil scientist and main investigator with the Canadian Potato Early Dying Network, suggested the condition
