Blocked tissues that transport water cause the telltale wilting and death of Potato Early Dying disease.

Potato Early Dying a silent yield killer

Industry network seeks to reduce impact of the disease

A national initiative to reduce the severity of a silent enemy in Canadian potato fields is claiming some early success halfway through its four-year program. The Canadian Potato Early Dying Network (CanPEDNet) is starting to learn more about verticillium wilt and how to deal with this major yield-limiting pathogen in commercial potato cropping systems, said

Shift in weather complicates sclerotinia decisions

Shift in weather complicates sclerotinia decisions

Canola is starting to flower and the canopy is wet, usually a recipe for sclerotinia, but perhaps not this year

Parts of Manitoba have taken a sharp turn from bone dry to very wet since the start of June, and that’s impacting the discussion around sclerotinia. “Because parts of the province have had lots of moisture and lots of humidity, we’re gearing up that it could be a bad sclerotinia season,” Justine Cornelsen of the


Clubroot and other crop diseases have startlingly similar transmission pathways and preventive measures as public health challenges such as COVID.

How canola diseases act like COVID-19

There are startling similarities between public health and plant health as coronavirus precautions reveal

With the COVID-19 pandemic, society is gaining a whole new understanding of how diseases spread and how following proper precautions can make a huge impact on slowing the spread. While the human stakes are lower for crop diseases, the economic stakes can be high — and the similarities between COVID-19 and crop disease management is

Use clubroot soil test as early-warning system

Manitoba Canola Growers Association members get one free test a year

Soil testing fields for clubroot spores, even if canola crops are not showing symptoms, is a good way to keep ahead of the disease, says Manitoba Agriculture’s oilseed specialist Dane Froese. “It’s a great way to get tested ahead of time and know if you are near high risk,” he said. If spores are detected,

Dr. Neil Gudmestad, of North Dakota State University, dives into the genetics of SHDI fungicide resistance during the 2018 Manitoba Potato Production Days.

Fungicide issues worse in U.S.

Boscalid and other early blight fungicides are facing down resistance in the U.S., but the issue hasn’t quite reached fever pitch in Manitoba

It’s not time to panic on boscalid resistance, at least not north of the border. The U.S. potato industry, including potato producers directly south in North Dakota, have noted a substantial downturn in both boscalid fungicide efficiency and the wider group of SHDI fungicides in general, something that could rob them of one of their


A close-up of a lower stem lesion on soybean caused by phytophthora.

Phytophthora a growing risk to soybeans

The once-rare infection is now the No. 2 cause of soybean root rot in Manitoba

The threat of phytophthora is on the rise in Manitoba. Results from a 2017 disease survey show it’s becoming common enough soybean growers will need to keep it top of mind as they plan their rotations this year. About 35 per cent of tested soybean crops in Manitoba were positive for phytophthora, although fusarium was

Is a soybean-canola rotation worth rolling the dice?

Is a soybean-canola rotation worth rolling the dice?

Most farmers aren’t jumping on a soybean-canola rotation, but explosive growth of soybean acres and their westward spread into canola country have some asking the question

Farmers better study up on the hurdles of a soybean-canola rotation before trying it in the field, Manitoba Agriculture specialists say. Soybeans have been a growing story in Manitoba, rising over the last decade to become one of the province’s main crops with almost 2.3 million acres planted in 2017. Combined with canola, another high-value

The bambara nut, seen here after being dug, is one type of legume that could benefit from its wild relatives.

Researchers break the wild-domestic barrier in legumes

They’re hoping to tap wild relatives for important traits 
such as disease and pest resistance

Domesticating plants to grow as crops can turn out to be a double-edged scythe. On one hand, selecting specific desirable traits, such as high yields, can increase crop productivity. But other important traits, such as resistance to pests, can be lost. To mitigate this, researchers often turn to the wild relatives of crops. These wild

Do you know how to identify this flax disease and when to look for it?

At the recent Crop Diagnostic School, Manitoba Co-operator reporter Allan Dawson spoke with Rachel Evans, extension agronomist with the Flax Council of Canada, about what flax producers can do to avoid pasmo appearing in their flax crops. Video editing by Greg Berg.

Weather conditions see crops quickly advance, disease, insect pressures low

Manitoba Crop Report and Crop Weather report for July 24, 2017

Hot and humid weather conditions across much of the province are advancing crops quickly. Winter cereals and some early seeded spring cereals are starting to turn. Areas in the Southwest, Northwest and Central regions are well below normal precipitation and would benefit from rain. Thunderstorms brought damaging winds and hail to some areas of Manitoba.
