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

By Melanie Epp February 21, 2018

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

The diamondback moth is capable of producing as many as four generations each year. The earlier they arrive and the better the conditions, they more they reproduce.

Why was 2017 an unprecedented year for diamondback moth?

Reviewing economic thresholds and  action plans to control this insect pest

By Melanie Epp February 20, 2018

Last year’s growing season was a freakish one for diamondback moth in Western Canada, and while the probability that an outbreak of this calibre will be seen in 2018 is very low, the possibility is always there. Knowing what to do and when to act can help you to get this insect pest under better […] Read more

Looking back on 2017’s biggest growing challenges

Agronomy tips... from the field

By Chadrick Carley November 16, 2017

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

White heads had popped up randomly throughout the durum field. The plants with the white heads were completely sterile and felt crispy, yet they were attached to a healthy, green plant.

Crop Advisor’s Casebook: What’s causing white heads in this durum crop?

A Crop Advisor's Solution from the October 17, 2017 issue of Grainews

By Dallas Funke October 20, 2017

Frank, who grows durum wheat, lentils, canola and soybeans south of Regina, Sask., called me mid-August in 2016 to discuss an issue with his wheat crop. He noticed white wheat heads popping up randomly throughout the field. “Could this be from heat blast, like in canola flowers?” he asked. “There are more of these heads […] Read more

Wheat midge 101: the basics of scouting

Growing soft white wheat or a non-midge-tolerant variety? Get ready to scout

By Julienne Isaacs June 29, 2017

It’s smaller than a mosquito, but more of a headache for Prairie farmers — wheat midge might look innocuous, but it can cause significant crop damage in Western Canada. Since midge-tolerant spring wheat varieties have become widely available, midge scouting has become a thing of the past for many Prairie farmers. However, with only one […] Read more

Don’t rush canola into cooler soils

Agronomy tips... from the field

By Rob Bishop May 24, 2017

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

By Lisa Guenther May 19, 2017

About 30 per cent of the 2017 crop is seeded, according to the latest Saskatchewan Agriculture Crop Report. But while the province as a whole is close to the five-year average, actual seeding progress varies tremendously across the province and even within regions. Farmers in the southeast have 60 per cent of the crop in […] Read more

A new species of midge lands on the Prairies

Researchers say this  new “anonymous” midge is not an imminent concern, but it’s worth watching

By Angela Lovell May 16, 2017

An anonymous midge species has been identified in Saskatchewan and central Alberta. The new species is similar to Swede midge (a species already present in Saskatchewan), but to this point does not appear to have caused significant, widespread damage in canola crops. Researchers are still trying to find out more about the as yet unnamed […] Read more
