The introduced invasive species spotted knapweed is easily identified once the plant produces its distinctive bright-pink flowers. But at this stage it is already well past the stage where controlling its spread is easy or feasible, warns the Invasive Species Council of Manitoba.

Spotted knapweed could do more harm than leafy spurge

The ISCM declared August Invasive Species Month and is highlighting the risks associated with the potential spread of spotted knapweed

The Invasive Species Council of Manitoba wants all Manitobans to be on the lookout for an invasive plant species now spreading across Manitoba that has the potential to do as much or more damage as leafy spurge. Spotted knapweed was first detected in southeastern Manitoba in 2009 but has more recently been found at sites

Crop Diagnostic School: It doesn't hurt to check your water source if you think your herbicide is underperforming

With the amount of time and expense producers put into spraying glyphosate, they need to know that their efforts will be rewarded with dead weeds as much as possible. But did you know there could be minerals hiding in your water source that can reduce glyphosate’s effectiveness? At the recent Crop Diagnostic School, Allan Dawson

Inter-row cultivator uses a camera and computer to get rid of weeds

Mechanical weed control was one of the features at Crop Diagnostic School last month in Carman. Here, Katherine Stanley of the University of Manitoba explains some of the technology the Garford cultivator uses that allow it to remove weeds from your crop without damaging it in the process.

Provide a healthy, competitive crop stand to help battle back weed pressures

“If you don’t put a crop plant there on that spot in the field, a weed’s gonna grow,” says Rob Gulden, professor of weed science at the University of Manitoba. Gulden was referring to one strategy producers can use to help fight herbicide-resistant weeds, and that is by increasing their seeding rates. In this interview with


Delegates try out the recently released Weedscout app during the Global 4-H Summit in Ottawa July 11-14.

Facial recognition technology can capture and identify the faces of weeds as well as humans

A new app will bring weed identification to the field with the click of a smartphone camera. That’s according to Bayer and its recently released Weedscout app, which compares a photo of a weed with a cumulative database and returns a list of potential matches. “As it’s used more and more, it’s designed to learn

MBFI research co-ordinator Kristelle Harper stands in front of the herd at the Manitoba Beef and Forage Initiatives Johnson Research Farm.

Putting spurge on the menu for research — and cattle

With an incoming learning centre and research ranging from rodent control to grazing systems and leafy spurge, 2017 looks to be busy for Manitoba Beef and Forage Initiatives

Manitoba Beef and Forage Initiatives (MBFI) is ramping up for 2017. Preparations are underway for a long list of projects at the collaborative’s three test farms outside of Brandon. “Some of them are continuing projects from last year,” said MBFI president Ramona Blyth. “Research is never just done in one year, so there’s the carry-over


Wild oats, known to be highly competitive with wheat, have declined in relative abundance, according to weed survey results.

Weed rankings shuffle in latest provincial weed survey

Wild oats are down, but experts are warning producers to take a closer look at their foxtail, it might not be the species they think

Green foxtail is still the province’s top weed, yellow foxtail is on the rise and wild oats have declined, according to last year’s Manitoba Weed Survey results. Wild oats, usually the second-most-abundant weed in the province, slipped to fourth in 2016, overtaken by both wild buckwheat and barnyard grass. Dr. Jeanette Gaultier, principal investigator of



Palmer amaranth seems to have slipped into North Dakota as part of seed mixes for conservation plantings.

The invasive weed is also really good at developing herbicide resistance

North Dakota extension personnel are warning farmers on that side of the border of the arrival of the invasive weed Palmer amaranth. The North Dakota Department of Agriculture and North Dakota State University Extension Service are advising farmers to scout new conservation plantings for Palmer amaranth, a very aggressive weed that has plagued cropland production
