Using clubroot resistant genetics and lengthening rotations are highly recommended practices for managing clubroot on the Prairies. But is there more farmers could do? “Ninety per cent of those clubroot spores can die with a two-year break, so one in three rotation, that’s really critical, if you have a shorter rotation than that, and you’re… Read More

As swath timing and harvest approach, it’s time to pay close attention to pre-harvest intervals. “PHI or pre-harvest interval is a really important concept to understand, and it’s actually a really easy concept to use,” says Keith Gabert, agronomy specialist with the Canola Council of Canada, in this episode of Canola School. “The labels are… Read More

Forage and hay production this year has been challenging, and livestock producers in much of the Northern Great Plains and the western half of North America are looking for alternative forage resources and feeding strategies. Zach Carlson, extension beef specialist at North Dakota State University, is looking at options for producers who might have canola… Read More

Lygus bugs attack several broadleaf crops, including alfalfa, flax, faba beans, lentils, and canola. They are a pest of concern that have been a focus for Hector Carcamo, research scientist at Agriculture and Agri-Food Canada, Lethbridge, Alta. He joins Kara Oosterhuis for this Canola School episode to talk about lygus bug species, the conditions they… Read More

Plot trials are a great way to gain preliminary research findings about a particular subject. Based just outside of Lethbridge, Alta., Farming Smarter’s primary focus is applied research that helps producers make informed choices around inputs, technology and management practices for their operations. Carlo Van Herk, research technician at Farming Smarter, walks Kara Oosterhuis through the… Read More

It’s been dry, windy, and hot across most of the Prairies this year, and an insect pest that you don’t typically see attacking canola is thriving in these conditions. Lyle Jensen, agronomist at AgroPlus, joins Kara Oosterhuis for this Canola School episode where they discuss grasshopper pressures and options for control. “As we’ve basically been… Read More

Cabbage seedpod weevil can cause considerable yield loss to a canola and other brassica crops, such as mustard. As adults, the pest is three to four millimetres in length, is ash-grey in colour, and has a prominent curved snout, similar to other weevils. Meghan Vankosky, field crop entomologist at Agriculture and Agri-Food Canada Saskatoon, joins… Read More

It’s been dry in parts of Western Canada heading into canola flowering, but has it been dry enough to hold off on spraying for sclerotinia? That’s a question many growers and agronomists in drought-affected areas have been asking themselves over the last week or two. There are really two basic factors to consider in the… Read More

It’s well-known that canola does not like heat during flowering. As soon as daytime highs rise beyond 30 degrees C — as we’re seeing through the current heat wave in Western Canada — the plant can become heat stressed, which leads to blasting and aborted pods. High temperatures can essentially cause a breakdown in communication… Read More

Getting the right spray quality and the right water volume can be a bit tricky, and when it comes to nozzles, there are a few factors to consider when picking the right one. When it comes to nozzle size and spray pattern, there are two important questions our expert for this Canola School episode asks:… Read More
