Researchers are hoping Canadian potato growers will soon be able to use an innovative approach to control wireworms. This method uses just a few grams of insecticide per hectare applied to cereal seeds that are planted along with untreated seed potatoes. It provides very good wireworm control for the whole…
Just because black cutworms don’t overwinter in Canada doesn’t mean they aren’t a threat to potato crops. The insects spend their winters in the southern United States but travel north on low-level jet streams and, once they cross the border into Canada, they look for a tasty food source. Black…
There are other, more sophisticated methods of testing for the presence of late blight spores in growers’ fields, but that’s precisely the reason Eugenia Banks selected a very simple test for her 2016 project.
Post-harvest potato storage expert Todd Forbush of Techmark Inc. in Lansing, Mich., says quality potato storage requires just two things: quality storage facilities and quality potatoes to store.
Sept. 29, 2016 – Second growth is a physiological potato problem induced by soil temperatures of 24 C or above and water stress. These two factors interact to limit the tuber growth rate, causing second growth. Inadequate soil moisture alone does not result in the initiation of second growth. Heat…
July 27, 2016, Prince Edward Island – While some areas on P.E.I. got a thorough soaking over the weekend, others are still thirsty for moisture. Water levels are still low in some areas of the province, reports CBC. | READ MORE
June 28, 2016, Manitoba – The crops continue to look very good, says Vikram Bisht in the Manitoba potato report from June 24. Most early planted crops are row closed and many are nearly so. The rainfall distribution has been very good, and very few fields need irrigation. The accumulated…
June 28, 2016, Alliston, Ont. – Irrigation was the order of the day on June 27, writes Eugenia Banks, OMAFRA potato specialist, in her latest update. Banks checked a few fields near Alliston, Ont., for early blight but did not find any lesions. The fields had been sprayed recently and…
June 23, 2016, Manitoba – Potato crops across Manitoba in general look very good, according to Vikram Bisht of Manitoba Agriculture, Foods and Rural Development, in his latest report. The early planted crops appear to be about a week ahead of last year. Many of these fields have crop canopy nearly…
May 27, 2016, Prince Edward Island – Prince Edward Island potato growers got a bit of a head start to planting this year, says Greg Donald, manager of the P.E.I. Potato Board. Donald estimated that between 65 and 75 per cent of the Island’s 2016 potato crop was in the ground…
April 28, 2016, Charlottetown – Christine Noronha, an entomologist with Agriculture and Agri-Food Canada’s Charlottetown Research and Development Centre, has designed an environmentally green trap that could be a major breakthrough in the control of wireworms, an increasingly destructive agricultural pest on Prince Edward Island and across Canada. In this…
April 26, 2016 – Eugenia Banks is offering free training sessions for potato scouts in May.  The first session will be held Monday May 30 from 9:30 a.m. to 3 p.m. at the Shelburne Agricultural Society Community Centre in Shelburne, Ont. The second session will be held Tuesday May 31…
  Careful management of irrigated potato crops over the long-term may help maintain crop productivity and nutrient availability within acceptable levels for agricultural production. This is the conclusion Agriculture and Agri-Food Canada (AAFC) researchers reached when they did a field experiment the year after completing a long-term irrigated potato rotation…
  Potatoes are a high input, high value crop and ensuring their success should not be left to chance. Certain variables, like the weather, cannot be predicted or controlled, but monitoring the weather can certainly help assess if problems affected by weather can occur. But suspecting there could be a…
Nov. 20, 2015, Prince Edward Island – A former manager of the P.E.I. Elite Seed Potato Farm says he’s been hearing there have been no outbreaks of bacterial ring rot in Prince Edward Island potatoes in five years. But the good news is tempered by the provincial government’s decision to discontinue…
