Validating economic thresholds for flea beetles can be tricky — especially when we know the damage the insect can do to the canola crop. Héctor Cárcamo, research scientist at Agriculture and Agri-Food Canada (AAFC) at Lethbridge, Alta., recently completed a study that confirms an economic threshold. The team at AAFC found that 25 per cent… Read More

When it comes to seeding depth of canola, there are many different opinions and recommendations out there. While there may not be a right or wrong answer — did you know you can potentially mitigate flea beetle pressure through seeding depth? Flea beetles can be one of the most detrimental insect when it comes to… Read More
On this episode of The Agronomists we’ve brought in two guests who know all there is to know about the pesky pests that seem to inevitably find their way into your crops. We are talking about the infamous wireworm, flea beetles that can wreak havoc on canola crops, and cutworms that, let’s face it, are… Read More
Flea beetles are a common insect pest in early growing canola across the Prairies. There are two important species of concern for canola (and mustard) growers: the striped flea beetle and the crucifer flea beetle. “The feeding is indistinguishable, but the striped flea beetle comes up earlier,” says James Tansey, provincial entomologist with Saskatchewan Ministry… Read More
Some insect pests overwinter in or near fields, while others blow in later in the season. For those that overwinter, early scouting is especially important. Following a relatively mild winter, some insect pests are making the most of dry conditions on many parts of the Prairies and are beginning to emerge and feed. For this… Read More
The organizations representing Canadian canola growers and the canola industry are welcoming a pair of Health Canada decisions regarding two active ingredients found in seed treatments for canola and other crops. Health Canada’s Pest Management Regulatory Agency (PMRA) released its final decisions following special reviews of the impact of clothianidin and thiamethoxam on aquatic insects… Read More
It’s been a challenging year on many fronts, but here we are, yet again, gearing up for the new season. And that’s exciting! Rootworm, western bean cutworm, and flea beetles are just a few of the insects that are on the watch list for Tracey Baute, field crop entomologist with OMAFRA. James Tansey, entomologist with… Read More
Weed control questions, millipede feeding, and a crusting quandary — it must be early June! This week’s Wheat Pete’s Word is a little longer than usual because there is just so much going on and so many great questions rolling in. Host Peter Johnson has got the answers this week to everything from tufted vetch… Read More
What’s bugging your crop? (See what we did there?) Scott Meers, independent agronomist and founder of Mayland Ag Consulting joins RealAg LIVE! host Shaun Haney for an informative and fun chat all about counting bugs. Well, not really. Also not all insects are bugs. Scott would want us to say that. Check out the video… Read More
Seeding is well under way across the Prairies and as farmers start seeding canola, flea beetles are likely the biggest pest of concern. For this Canola School, correspondent Kara Oosterhuis sits down with Dr. John Gavloski, the provincial entomologist with Manitoba Agriculture and Resource Development. Even if canola isn’t in the ground yet and as… Read More
If you were farming on the western Canadian Prairies in 2019, you’ll most likely shudder at the thought of flea beetles, knowing how rampant they ran throughout the spring. Syngenta recently rolled out a new flea beetle option for seed treatments in Western Canada, called Fortenza Advanced, that has the active ingredients sulfoxaflor and cyantraniliprole…. Read More
Every year, many canola producers seem to face the same challenge across the board — how do we manage all these flea beetles? The answer to this question is quite often pointed towards one main action — seed treatments. In this episode of the Canola School, Gregory Sekulic, agronomy specialist with the Canola Council of… Read More
There are few things as frustrating as spending untold hours of preparation and seeding (and finally some rain!) only to have a host of insects crawl or fly in and eat the crop’s yield potential. In this episode of the Canola School, provincial entomologist for Saskatchewan’s Ministry of Agriculture, James Tansey, gets outside to talk… Read More
Seeing dimpling on your canola leaves? Stem feeding? Chances are, it’s flea beetles causing the damage. This year in the southern prairies, flea beetles are becoming a significant issue, most likely in part due to dry conditions. And with neonicotinoids continuing to hit headlines, flea beetle control could become even more difficult in the coming… Read More
As temperatures warm, fields across the west are starting to see flea beetle emergence, and cotyledon defoliation. And that has producers wondering about when to take action. “There’s been some discussion about different threshold levels,” says Errin Willenborg, agronomist with Federated Co-op Ltd. The discussion stems from confusion around two listed thresholds — the 25… Read More
