When it comes to economic impact, ascochyta — also referred to as mycosphaerella blight — is a serious concern in peas, lentils and chickpeas. In this Pulse School episode, we talk to Nevin Rosaasen, about how to scout for ascochyta, and the importance of timing when it comes to fungicide application. “When you are going out… Read More

For parts of Western Canada, the rain keeps on pouring. Early wet conditions could be conducive to root rot problems in pulses. Fortunately, for three of the four main culprits —rhyzoctonia, fusarium and pythium, the plants will generally grow through the vulnerable early seedling stage if a seed treatment has been applied, notes Robyne Bowness-Davidson, pulse… Read More

As peas and fababeans emerge, at least one potentially devastating pest already has made an appearance — the pea leaf weevil. In this Pulse School episode, we talk about how to deal with the weevils if you are seeing them now, economic thresholds for control, and how to avoid them in the future. Pulse research… Read More

Taking a break from peas or lentils for six years is a tall order for fields where aphanomyces has been a problem. Are there in-field options or tools for managing this relatively new disease? Syama Chatterton, pulse crops pathologist with Agriculture and Agri-Food Canada in Lethbridge, has been conducting field trials across the prairies over the last two… Read More

With seeding just two months away, Canada’s pulse crop industry is in limbo, facing the threat of not having access to its largest export market as of the end of March. India’s government says it will not extend a derogation (or an exemption) allowing pulses from Canada to be fumigated with methyl bromide upon arrival, rather than… Read More

“Herbicide layering” looks to be an effective approach to managing hard-to-control cleavers in pulses. As Eric Johnson, weed scientist at the University of Saskatchewan, explains in this Pulse School episode, herbicide layering is the application of different modes of action sequentially. It usually involves a pre-seed soil-applied herbicide, such as sulfentrazone, ethalflurolin or pyroxasulfone, ,… Read More

Pea aphids populations have been reaching problematic levels in some parts of the Prairies over the last few weeks. In this Pulse School episode, Dennis Lange, provincial pulse specialist in Manitoba, says they’re still a concern in some areas. “We’re at the stage where some of the later seeded pea fields are in the late flowering stage, pods… Read More
