Saskatchewan bugs to watch for in 2019

Low survey results in 2018 could be good news for Saskatchewan farmers this season

The 2018 pest survey results for Saskatchewan look like good news for the 2019 season. Grasshopper, pea leaf weevil and diamondback moth populations were all low in 2018. Large numbers of Bertha armyworm moths were caught in the Outlook and Watrous areas, but these do not necessarily predict 2019 populations. Saskatchewan Ministry of Agriculture integrated […] Read more

When conditions are right, bertha armyworm damage can happen quickly.

Patience pays with bertha armyworm

Experts recommend holding 
the spray until you scout, 
and counting beneficial bugs

Late last summer, a canola field heavily infested with bertha armyworm in western Manitoba created a lot of fuss on Twitter, proving, yet again, just how localized population spikes can be in some areas. While sudden population spikes can cause panic, experts recommend that growers only take measures after they’ve got a good handle on […] Read more


Although there was lots of green in the field, some areas were patchy where the plant stand was thin. In other spots, entire rows were missing plants. There was no obvious pattern.

Crop Advisor’s Casebook: What’s attracting seagulls to this canola field?

A Crop Advisor's Solution from the January 23, 2018 issue of Grainews

Paul, who farms 3,500 acres north of Camrose, Alta., was convinced cutworms were taking a bite out of his canola crop. It was mid-June last year when he noticed his canola plant stand was thin. Also, many seagulls were circling the field. He thought cutworms were attracting the birds, as well as damaging his crop […] Read more

Looking back on 2017’s biggest growing challenges

Agronomy tips... from the field

Looking back on issues that growers had to deal with during the 2017 growing season, two things come to mind: insects and weather. In the spring, several regions across the Prairies experienced heavy flea beetle and cutworm pressure in their canola crops, along with some diamondback moth pressure later in the season. Keep in mind […] Read more


Pea leaf weevil is a common pest in field peas and faba beans, primarily affecting crops grown in Alberta and Saskatchewan.

Pea leaf weevil moves into new territory

Pea leaf weevils are on the move. Know what you can do about them

Pea leaf weevil numbers are on the rise. In fact, according to Scott Meers, an entomologist with Alberta Agriculture and Forestry, they’re moving into areas where producers have no experience with them at all. “We’ve seen a major expansion in the past several years of pea leaf weevil, especially up the west side of central […] Read more

Don’t rush canola into cooler soils

Agronomy tips... from the field

Your flea beetle management strategy this season is going to depend on what type of weather conditions and soil temperatures experienced in the days leading up to seeding. Striped flea beetles are going to be a significant threat to your emerging canola, and were responsible for about 90 per cent of the feeding damage we […] Read more


Swede midge larvae.

Midge scouting in canola

Scouting is an important component of management. If you don’t know what’s in your field, you can’t evaluate what control measures to use. Yearly scouting is needed to assess what pests exist in fields, as populations don’t always remain constant. For example, in 2016 there were higher counts of cutworm but lower incidence of Bertha […] Read more



The severity of wheat midge this season will depend on the weather.

Protect yourself against wheat midge

Wheat midge may be on the rise this year, especially in southeastern Saskatchewan

Farmers in most areas of Saskatchewan need to be aware of wheat midge, says Scott Hartley, Sask­atch­­e­wan’s provincial special­ist for insect pest management. Specifically, eastern Sask­­­­atch­ewan, primarily east central and southeast. There’s another section from Prince Albert south, “extending quite a ways, at least down to close to Bethune.” Midge threats in Alberta aren’t as high, but are more pronounced east of Edmonton and in the Peace region. However, Alberta […] Read more

Grasshopper numbers are climbing in Alberta. They can thrive in dry weather.

Be on your guard for grasshoppers

Grasshopper numbers are up in Alberta. Warm dry weather will give them an edge

Grasshoppers were found in higher numbers in 2015 in Alberta. Unfortunately, the same is expected for 2016, says Scott Meers, Alberta Agriculture insect management specialist. The Peace region, the extreme north and northwest areas of Alberta, are expected to have high grasshopper numbers. Farmers west of Edmonton also saw high populations last year and the […] Read more
