Crop disease reporting tool is now live

By
The 2022 version of a tool that alerts producers to emerging disease threats is now available. The Quick Disease Reporter Tool was created by the Prairie Crop Disease Monitoring Network. It allows users “to make general reports of diseases in common crops” across the Prairies. “This information can be used to identify regions where Prairie crop
Some bacteria found on corn silk are reduced, while some proliferate when exposed to fusarium.

New research finds natural bacteria in corn may help against fusarium

Certain types of bacteria multiply in corn silk when exposed to the pathogen

By
University of Guelph researchers have found corn silks naturally contain diverse microbes, a finding that may point to a new strategy to help protect cobs from fungal infections. Why it matters: The discovery may improve breeding and farming practices to avert costly and harmful fungal outbreaks. The study was led by Manish Raizada, a professor

Potato Early Dying a silent yield killer

Industry network seeks to reduce impact of the disease

By
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

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

By
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

How canola diseases act like COVID-19

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

By
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

By
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,

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

By
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

Phytophthora a growing risk to soybeans

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

By
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?

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

By
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

Researchers break the wild-domestic barrier in legumes

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

By
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
