Six- to eight-year crop rotation to manage root rot in pea and lentil crops is a long rotation. But that’s about the only option that pulse growers have when it comes to managing the devastating disease. So, researchers continue to look for control options that can help reduce the damaging impact of the disease.
“Root rot is an important and intractable issue for pulse growers. There is no genetic resistance currently available, and seed treatments are only effective on some of the pathogens and only provide protection for a few weeks after seeding,” says Michelle Hubbard, research scientist with Agriculture and Agri-Food Canada in Swift Current, Sask. “It’s a problem with not a lot of solutions.”
