Cabbage seedpod weevil.

What’s bugging you?

These three beetles are the latest addition to the pest spectrum in Manitoba

Manitoba farmers have, in recent years, found themselves hosts to three new uninvited guests. That was the message from John Gavloski, Manitoba Agriculture and Resource Development entomologist, to the Ag in Motion Discovery Plus virtual farm show this summer. He said all three of these new pests are types of beetle, and all three first

Keep an eye out for these three ‘new’ insect pests

Entomologists are tracking the progress of cereal leaf beetles,cabbage seedpod weevils and pea leaf weevils across Manitoba

A provincial entomologist is asking farmers and agronomists to keep their eye out for three pests making inroads in Manitoba. Why it matters: Provincial entomologist John Gavloski has a watch list of pests starting to creep their way into Manitoba. The cereal leaf beetle was first spotted in Manitoba in 2009 and has spread from


It might look bad, but there’s a pretty good chance those canola 
volunteers aren’t actually doing that much harm.

What to do with those yellow soybean fields?

Now is also the time to scout for Bertha armyworms and diamondback moth

That bright yellow volunteer canola in your soybeans might look worse than it really is — so before trying to control it, consider whether it makes economic sense. That’s the advice Tammy Jones, Manitoba Agriculture and Resource Development’s (MARD) weed specialist gave in an interview following a Crop Talk webinar July 15. (Jones’ last day

The province has urged canola growers in parts of the province to be on watch for diamondback moth larvae and pupae.

Heads-up on diamondback moth

Eastern Manitoba and the southern Interlake have been hot spots for the province’s diamondback moth trapping program this year

Canola growers in eastern Manitoba and the southern Interlake should be keeping an extra eye out for diamondback moth this year, experts have warned. Manitoba Agriculture and Resource Development has noted exponentially higher counts of diamondback moth in those areas, something provincial entomologist John Gavloski has linked to windy weather in June blowing adult moths

Prairie Pest Monitoring Network launches website

The resource will help farmers and agronomists scout and identify pests

The Prairie Pest Monitoring Network (PPMN) has launched a new website. The PPMN is a Prairie-wide insect pest monitoring group that provides valuable information, predicts insect risks, monitors insect populations and offers information to growers and agronomists to help them scout for pests, time their scouting activities and to make decisions about using chemical controls. “We are really excited to be launching this new website,” said Meghan

Armyworm on the march in Manitoba

Cereals and grasses are taking a hit from armyworms, one of several pests that tend to blow in as adults from the south

Manitoba has an armyworm problem. Eastern, central and southwestern Manitoba, as well as the Interlake have all reported spraying from farmers looking to keep the pests from chomping down on their cereal and forage grasses, according to Manitoba Agriculture and Resource Development. “There’s been some control in pretty much every agricultural region except the northwest,” provincial entomologist

Prairie pest report says grasshopper risk low

This despite general upward trend in the populations across Manitoba and Saskatchewan

This year’s grasshopper threat remains light to very light across Manitoba, according to survey data released by the Prairie Pest Monitoring Network on April 27. The data is based on surveys done in 2019. These included nearly 3,200 grasshopper counts across the Prairie provinces between May 1 and August 31. Maps in the report show

Pests like the corn leaf aphid could be in areas thought free of it, according to new research.

Crop pests often missed as they move into new areas

Finding where pests exist in the early stages of movement into an area are key to control

Insects and diseases that damage crops are probably present in many places thought to be free of them, new research shows. Pests that have not been reported in a certain area are usually assumed to be absent, but analysis by the University of Exeter shows many pests are “currently unobserved, but probably present” (a likelihood


Grasshopper control continues in oilseed crops, hay yields seen significantly lower

Manitoba Crop Report and Crop Weather report for August 13

Southwest Region Warm temperatures this week have quickly advanced crop maturity, together with cooler than normal overnight temperatures. Rain over the weekend and into Monday occurred throughout the region but amounts varied from 0.4 mm at Lake Audy to 37 mm at Bede. Areas along Hwy 16 are still below normal moisture accumulation this summer.

Nine pests to watch for if you’re growing flax

Dr. James Tansey, Saskatchewan Agriculture’s insect specialist, reminded farmers at a Saskatchewan Agriculture conference in Weyburn, Sask., that “plants are not a passive part of the environment.” Flax produces poison in the form of cyanogenic glycoside (cyanide) that is toxic to several insects. However, your flax crop may still need some help protecting itself from
