Potato Consumption Rebound Puts Squeeze on Reduced Acres

Potato acres across Canada are expected to be down for 2020, due to contract volume cuts in March as the pandemic lockdown hit North America. After a three-month long rollercoaster ride for the potato industry, there’s good news on the horizon. “The rebound is happening faster than anyone anticipated,” Kevin MacIsaac, general manager of the United Potato Growers of Canada, says in a phone interview. “We thought we would have far too…

Rainfall in Manitoba Potato Regions Below Normal

Rainfall in Manitoba potato growing areas has been 35 to 70 per cent of normal levels with less rain having fallen over the last week, the June 26 provincial potato report from Manitoba Agriculture’s Vikram Bisht says. Potato heat units are near or just above normal, the report notes. Crop emergence and stand are looking good with some late planted fields just emerging.

Direct seeding with minimal tillage

First of its Kind

A farmer in Manitoba is trying out a first of its kind seeding experiment — using direct seeding with minimal tillage to try and reduce soil compaction and erosion in his fields. Chad Berry has been practicing zero tillage seeding on his grain crops for years but had always wanted to do it on his potato fields. However, he didn’t feel his potato planter would work for it, so when he upgraded…

Potato Update for Ontario

Fields across Ontario are at very different stages ranging from flowering and bulking in south western Ontario to still emerging in late areas such as Shelburne-Melancton. Most of the fields planted in early May in central Ontario are filling the rows, and tuber size is good! I saw leaf burning caused by heat and excessive evapo-transpiration. Plants overgrow this leaf burning lesions. Poor emergence has been noticeable in a few fields. Possible…

Working Together on Research

After more than a decade spent developing a research network, the Canadian potato industry is now taking full advantage of funding from the Canadian Agricultural Partnership. When Canada first launched Growing Forward [now called the Canadian Agricultural Partnership (CAP) more than a decade ago, the potato industry was interested but knew they had some work to do before they could take full advantage of the program. “There was a real need for…

Dip Test Protocol to Determine Neonicotinoid Insecticide Resistance

An important factor in managing insecticide resistance is to know the effectiveness of the product which is going to be applied. This can be accomplished by using dip tests, a simple technique in which adults or larvae are immersed for a few seconds in insecticide solutions. The mortality rate determined for each insecticide indicates the products which are likely to be most effective under field conditions. Dip Test Items Although dip test…
