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, 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
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, 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
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
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
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
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
The start of the 2011 growing season was challenging to say the least. Wet weather and unseasonably cool conditions in the majority of the west had producers stressed out and wondering if they would get a crop in at all. That was the case in fact in large areas of Saskatchewan and Manitoba. Fast forward… Read More
When the conditions are right, flea beetles move quickly and devastate quickly. The bugs are the most chronically damaging insect pest of canola in Western Canada. They inflict the most damage on canola at the seedling stage, inhibiting proper plant growth and delaying maturity. They will feed on more mature plants, but canola at later… Read More
In this episode of the Canola School, Troy Prosofsky discusses the impact that the flea beetle is having on the Western Canadian canola crop. Troy also talks about the evaluation of flea beetle damage and when or when not to spray to control the pest. Flea Beetles can be terrible pests and if the damage… Read More
With the advent of the introduction of seed treatments like Helix Extra, we do not hear as much about flea beetles anymore. The reality is that they are still around and could have an impact on your yield. Forecasts for this pest are difficult and we require the pest to eat the plants in order… Read More
By Garth Donald, CCA,Western Canadian Manager of Agronomy, Dynagra I can honestly say that it has been a while since I have been on my hands and knees trying to see if there is any life left in a canola plant but this last week it has occurred more than I would like it to…. Read More
