Canola School: The trouble with flea beetles…

Less than ideal conditions have slowed down canola development and left the crop vulnerable to tiny 2.5 millimetre beetles in some areas this spring. Flea beetles are the number one pest in canola on the Western Canadian Prairies. In this Canola School episode, we talk with Tyler Wist, entomologist with Agriculture and Agri-Food Canada in Saskatoon, about how… Read more »

Entomologist Recommends Proactive Approach to Neonics on the Prairies

Regulatory restrictions are not on the radar in Manitoba, but the province’s agriculture entomologist suggests farmers in Western Canada should ask themselves “why?” before using neonicotinoid seed treatments. The Ontario and Quebec governments are restricting the use of insecticide-treated seed in response to concerns about neonics hurting bee health, but there haven’t been the same problems with pollinator populations… Read more »

Canola School: What Caused Premature Ripening? Tips for End of Season Scouting

While you’re in the field checking canola to see if it’s ready to be cut, or perhaps already swathing or harvesting it, it’s also a good time to assess the toll disease took on your crop. Sclerotinia, blackleg and clubroot can all cause premature ripening, as disease symptoms become more obvious at the end of the season,… Read more »

This Cinderella Crop is Beginning to Act Like a Real Princess

It’s rare to find a western Canadian farmer who doesn’t have a tale to tell of the roaring comebacks canola has made in a growing season. Sure, there have been some wrecks — wicked windstorms that flip swaths or hail that leaves nothing but sticks — but the “Cinderella crop” (you’ve heard the song, right?)… Read more »

Canola School: Estimating Flea Beetle Damage & Protecting Beneficial Insect Populations

We’ve finally got a crop up in Western Canada, but as soon as those tiny canola plants emerge the attacks begin. Seedling blights are one concern at the establishment phase, but flea beetles can be a huge threat to the canola crop. In this episode of the Canola School, Lyndsey Smith is joined by Canola… Read more »

Flea Beetle Pressure Very High: Farmers Encouraged to Scout Daily

If you scouted your canola field for flea beetle damage even a day or two ago, it’s time to get out there and do it again. Kristen Phillips, agronomy specialist in Manitoba for the Canola Council of Canada, is reporting a few thousand acres near Brandon will have to be reseeded because of excessive flea… Read more »

Flea Beetles: A Plan of Attack for a Cool Spring

Flea beetles, those tiny, hungry pests, feed on seedling leaf tissue in your canola fields almost every season. Their feeding on young canola plants causes the most economic damage. Understanding the pest and its lifecycle can help determine when control may be necessary, even if you’ve used a seed treatment. The two dominant species of… Read more »

Flea Beetles, Cutworms Have New Enemy in Lumiderm Seed Treatment

DuPont announced today that Canada’s Pest Management Regulatory Agency (PMRA) has granted approval for the registration of Lumiderm insecticide seed treatment. DuPont Lumiderm insecticide is a new seed treatment product for canola growers containing the active ingredient cyantraniliprole, a Group 28, anthranilic diamide insecticide that provides early season control of flea beetles, both striped and… Read more »

What do Tram Lines Have to do With Insect Management?

What, indeed. If you just read the title and aren’t sure, the short answer is nothing. The longer answer, however, is that tram lines may make scouting for insects easier and more thorough, and thus beneficial. Not convinced? Read on. Some insects are predictably found on the edge of the field — like flea beetles,… Read more »

Pests to Watch Out For In Alberta In 2013

If there’s two things I learned from the GIJOE cartoons in the eighties it’s that 1) GIJOE must have a strict catch and release policy because I don’t recall any members of COBRA being killed and they come back every week. 2) Knowing is half the battle!(they said it at the end of every episode)… Read more »

Canola School: Are Striped Flea Beetles Resistant to Seed Treatments?

It’s no secret that the striped flea beetle is a tougher opponent than the more common crucifer flea beetle. This canola pest tends to emerge earlier than the crucifer type and isn’t as easily killed by commonly used seed treatments. That does not mean, however, that the striped flea beetle is resistant to neonicotinoids, as… Read more »

Canola School: Identifying Crucifer and Striped Flea Beetle

The flea beetle is a menace to canola crops.  Typically seed treatments like Helix Xtra and Prosper have controlled flea beetles with ease and uncontrollable populations were relatively rare.  The feeding of seed treatment protected plants controlled the crucifer flea beetle which was great for farmers. The striped flea beetle has been showing up in… Read more »

FarmTech 2012 – Looking Ahead to Potential Pest Problems In Alberta

Assessing risk is a crucial part of any producer’s pest control strategy. If you don’t know what to look for or how to look for it, you are setting yourself up for some potentially costly problems. That risk assessment starts with a good knowledge of the previous year including hotspots for activity, and overall movement… Read more »
