With no new products in the pipeline and fewer options due to re-evaluation, resistance or supply issues, producers need to be nimble when it comes to weed control options.

Living without Linuron in the tank

Growers will have to alter practices and mix and match other products to control weeds

When the 2020 re-evaluation of herbicide Linuron dropped the application rate for potatoes, growers thought they would be off the hook until 2023, when the new rate comes into effect.  However, the registrant ran into regulatory issues after sourcing a technical active ingredient from a new provider. That pushed back production, causing supply issues.  “It […] Read more

‘Expedited’ potato wart survey helps make case for P.E.I., CFIA says

National survey done 'ahead of schedule'

A national survey finding no potato wart in any “unregulated” Canadian fields should offer the reassurance on Prince Edward Island potatoes that trading partners such as the U.S. are now looking for, the Canadian Food Inspection Agency says. CFIA on Thursday reported it has completed this fall’s national survey for the soil-borne fungal potato disease […] Read more


A tractor-mounted snowblower runs through rows of piled-up surplus potatoes on a field near Victoria, P.E.I., about 35 km west of Charlottetown, on Dec. 20, 2021. The shredded potatoes are expected to break down over the winter as compost. (Screengrab from P.E.I. Potato Board video)

Feds put up funds toward managing P.E.I. potato surplus

Ottawa budgets $28 million for distribution and disposal

Prince Edward Island potatoes locked out of the U.S. export market will go either to food banks or “environmentally-sound” disposal with new federal funding. Federal Agriculture Minister Marie-Claude Bibeau on Monday announced $28 million “to support the diversion of surplus potatoes, including help to redirect surplus potatoes to organizations addressing food insecurity and support for […] Read more

Waneta treated with Gibberellic Acid (GA) shows strong, uniform early emergency on the left compared to the control on the right during the WD Potato Ltd. GA trials in 2020.

Treatment could manage chipping potato size

Gibberellic Acid could be a solution to using potato varieties too large for chipping

Potato growers know that size, consistency and uniformity matter to the bottom line and non-marketable potatoes at harvest can chip away at profitability.  Take the Waneta potato; a good chipper variety appreciated by growers but panned by some processors due to its larger size.  In 2020, Mark VanOostrum, supply manager at WD Potato Limited, along […] Read more

Fields can present with a type of herbicide injury, but the symptoms can be mimicked by non-herbicide injury sources like root-lesion nematode infestations in this photo.

Herbicide injury rising in potato fields

Knowledge and preventative management can mitigate most instances

The source of potato herbicide injury isn’t always easy to pin down, especially when the usual suspects aren’t the guilty ones.  During a recent Ontario Potato Board webinar, Andy Robinson, extension potato agronomist at North Dakota State University/University of Minnesota (NDSU/UMN,) said pinpointing how herbicides came into contact with a plant is often a challenge […] Read more

Fall and full-season cover crops show promise in potato trials

Some varieties have shown yield increases and erosion control

Cover crop trials in Prince Edward Island potato fields are yielding promising results. Over the last two years, Ryan Barrett, research and agronomy specialist, Prince Edward Island Potato Board, has run fall-seeded and full-season cover crop trials to assess if there are an overall soil and potato harvest benefit. Why it matters: An estimated 80 […] Read more

Growers check out the hills in Chad Berry’s direct-seeded potato demonstration.

Direct-seeded potatoes show no harvest hit

Both yield and quality were comparable in an initial trial comparison of traditional spring tillage and direct seeding

The amount and quality of the potatoes coming off Chad Berry’s field last fall weren’t that much different from one side to the other, but one half came with a lot less tillage. Results are in from the 2020 field-scale trial, which featured a side-by-side comparison of conventional spring tillage and direct-seeded potatoes. Why it […] Read more
