Pests, such as corn rootworm, continue to evolve and so does the technology required to control these these yield-robbing insects. At Canada’s Outdoor Farm Show earlier this month, Bayer Crop Science launched SmartStax Pro with RNAi technology, a new mode of action to help defend corn plants against the pest. David Kikkert, Bayer Crop Science’s… Read More

Corteva has announced plans to launch its new Vorceed Enlist corn varieties in Canada for planting in 2024. Vorceed Enlist corn combines three modes of action for above-ground insect protection and three modes of action for below-ground insect protection, including a new RNAi mode of action. It also includes tolerance to four herbicides – 2,4-D… Read More
There are so many insects in the world that most of them likely haven’t been described yet. From some of the more common insects, such as the flea beetle, to a lesser-known such as a the beet webworm, this episode of The Agronomists tackles as much as we can in an hours’ time. Host Lyndsey… Read More
Transgenic traits that defend corn plants against against damaging corn rootwoom have been around since 2003. But in recent years, farmers have seen growing resistance to these traits and researchers and seed companies are working to preserve the effectiveness of the technology while also develop new ways to combat the yield-robbing pest. One of those… Read More
Corn rootworm resistance to Bt proteins and hybrids is a growing concern for Ontario corn producers. In this video report from Ontario Diagnostic Days 2021, University of Guelph research scientist Jocelyn Smith helps growers understand corn rootworm’s life cycle and how to rate corn roots for rootworm injury. She also discusses how growers can work with researchers to… Read More
Corn rootworm can be a major yield-robber and this year more than most, it’s on everyone’s minds. Amanda Craven, agronomist at PRIDE Seeds is joined by Bernard Tobin for this Corn School episode to talk resistance management, how rotation helps, and how corn rootworm affects yield. “What we’re seeing this year, in our corn-on-corn fields,… Read More
Corn and soybean insects and disease are the focus of Day 3 of Ontario Diagnostic Days. The annual Ontario field crop diagnostic days held at Ridgetown, Elora, and Winchester are again virtual in 2021. On this episode, host Shaun Haney is joined by OMAFRA field crops entomologist Tracey Baute to discuss growing concern about corn rootworm… 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
Corn rootworm, manure, and soybeans — farmers don’t often hear those three words in the same sentence but we’ve come to expect the unexpected in 2020. With growing resistance to corn rootworm traits in Ontario, many farmers who typically plant continuous corn will look to control the pest by expanding rotations to include soybeans. But… Read More
The growth of Bt resistant corn rootworm in the U.S. and now Ontario has many growers asking if the traits they purchase to defend their corn crop will stand up against the pest. It’s a question Dan Wright and other seed industry executives are hearing more often these days. But Wright, Syngenta Canada’s head of… Read More
Resistance to Bt corn rootworm hybrids has developed in Ontario and growers are asking: what’s the best strategy to control the yield-robbing pest if in-seed technology fails? Resistance has been confirmed in several fields in Huron, Perth and Durham Counties in Ontario and the problem is likely even more widespread, says Tracey Baute, Ontario Ministry… Read More
If you’ve ever adopted a new way of doing things after attending a field day or conference, do you let the researcher or extension staff know? Sometimes, research can be a rather thankless job, and many researchers don’t hear back on their work being applied on-farm. Peter “Wheat Pete” Johnson came across just such an… Read More
Harvest is rocking and rolling for most corn and soybean growers in Ontario save for @WheatPete himself who took an equipment breakdown as a chance to get the Word done early this week. This week’s Wheat Pete’s Word covers a lot of ground, including the why behind high test weight corn, the nitrogen connection to high… Read More
How’s wheat planting coming along? Are you all done? Call 1-888-746-3311 or tweet @WheatPete to leave your feedback and questions for Wheat Pete! In this instalment of Wheat Pete’s Word, resident agronomist and host Peter Johnson covers a long list of topics, including what wheat plant populations should look like in fields that have already emerged… Read More
Canadian corn growers will have access in 2014 to a novel source of corn rootworm protection as Syngenta Canada rolls out its Agrisure Duracade trait. The Duracade trait is the first corn rootworm trait launched with insect resistance management and the preservation of technology durability in mind, says Syngenta in a press release. It will… Read More
