Canadian potato output rises in 2023 

Alberta vaults to first place in provincial potato production

At 32.063 million hundredweight of potatoes this year, Alberta vaulted from third to first place as it improved on the previous year’s crop of 26.813 million. Manitoba moved into second spot from third with its harvest of 29.760 million cwt. following last year’s 26.139 million. Prince Edward Island saw its output reduced in 2023 to 25.813 million cwt. from 27.789 million. In 2023, the trio combined for 68 per cent of Canada’s total potato harvest of 128,801 million cwt.

Potatoes see big benefits from water stewardship project

Farmers studied the benefits of in-field and field edge projects for themselves and the community

Improved water stewardship on potato fields in the Lake Winnipeg basin could provide a surprising amount of community benefits, a recent project showed. “Those numbers were way bigger than I would ever expect,” said farmer Chad Berry. Berry, who owns Under the Hill Farms near Cypress River, was one of four farms (covering 34,000 acres)

Rethinking phosphorus acid and phototoxicity

Most leaf damage is cosmetic, not yield-busting, according to recent trials

Potato growers who use foliar phosphorus acid to lower the risk of storage loss might not need to be so picky when it comes to application, according to recent research. Until now, the need to avoid phototoxicity during application has been emphasized. Producers were advised to apply early in the morning or risk chemical burn on potato leaves. However,


Trials with the potato vine crusher have shown up to 94 per cent reduction in weed germination.  photo:

Old invention shows promise for weed control in potatoes

Originally designed for insect larvae, the potato vine crusher lowers germination rate of weed seeds

An invention originally designed to control European corn borer in potatoes has shown potential to reduce weed seeds during potato harvest. Dr. Andrew McKenzie-Gopsill, a research scientist with Agriculture and Agri-Food Canada, recently discussed the advantages of minimizing weed seeds during harvest to reduce pressure in potato crops. Then a colleague suggested an invention that

European corn borer might prefer grain crops normally, but it’s not opposed to settling into a potato crop too if conditions are right.

Corn borers develop taste for potatoes

Canadian potato growers found a new insect foe in the 2015 season — European corn borer. Ordinarily the pest prefers maize and other grain crops, but when conditions are right it will move on and hit other crops hard, including potatoes. Ian MacRae, an extension entomologist at Minnesota’s Northwest Research and Outreach Center, told Manitoba

PVY control depends on better understanding of aphids

After years of decline, the industry is seeing infections, not only increase but become more difficult to detect

Russell Groves has noticed a troubling trend for potato seed growers in his home state of Wisconsin in recent years. The University of Wisconsin entomologist specializes in insect-transmitted vegetable plant diseases, and he says after a period of decline, potato virus Y (PVY) infections have begun to increase for seed potato growers. “From about the


Devastating new potato disease headed north

The disease, which causes brown stripes in potatoes, 
has spread like wildfire since being found in Texas in 2000

Manitoba growers haven’t seen zebra chip disease yet — but it’s only a matter of time, says John Nordgaard. The transplanted North Dakotan manages a potato operation for Black Gold Farms near Piersall, Texas, which he describes as one of the epicentres for the disease, which results in striped chips that look like a white

Irrigation challenges highlighted in 2012

After a couple of challenging wet seasons, the spring of 2012 looked like it was off to a good start. Dry, workable soils led to one of the earliest planting completions in the history of the potato business in Manitoba, and growers were looking forward to a successful season. However, that planting season was only
