Differences revealed between old and new corn hybrids

Nutrient uptake, leaf architecture and planting densities examined

By
Research using tissue samples from corn fields is not a new concept, but a recent sampling study has uncovered interesting insights. The Corn Era Project has revealed shifts in production, including differences between 1980s hybrids and those of today. The goal of the project was to understand what’s changed in physiological terms when comparing modern […] Read more

The challenge with Bt

Insects are developing resistance to the formerly bulletproof building block of corn hybrid traits

By
The United States Environmental Protection Agency (EPA) is considering a ban on some Bacillus thuringiensis (Bt) corn and cotton hybrid traits in an effort to slow the proliferation of resistant pests. In Canada, where the number of control options is limited, this move might be a cause for concern. Why it matters: Tools to control […] Read more

Making the corn switch decision

Those who switched hybrids during 2019’s late planting season generally had more success

By
The 2019 planting season forced farmers to make more complex corn seed and planting timing decisions than they have in years. A wet and cool spring kept many farmers in Ontario out of fields until June and in some cases, for risk takers, July. Farmers who planted shorter-season corn hybrids generally made the right choice […] Read more

Managing corn mycotoxins needs scouting, hybrid choice

Farmer can reduce risk of mycotoxins, including through insect and spore management

By
Generally dry conditions have reduced the threat of mycotoxins in corn this year, although rains during humid days could change that as corn moves to tasselling and silking. However, Dave Hooker, of the University of Guelph’s Ridgetown College, says that historical monitoring of mycotoxin levels by the Ontario Ministry of Agriculture Food and Rural Affairs […] Read more

Bringing high-tech down to earth

These Exeter-area brothers have embraced multi-hybrid planting — but so far results are mixed

By
When farmers Mike and Geoff Strang went looking for a new planter, they weren’t content with buying the latest technology off the shelf. They took their new Kinze 3600Tr planter home and modified it so they can now sow two different corn hybrids at variable rates according to varying soil conditions and yield potential. The […] Read more

A multi-hybrid planter rebuild

By
How do you take a split hybrid, twin row planter and make it plant dual hybrids one in the front planter row and one in the back? It takes ingenuity, mechanical know-how and some help from eBay. Mike and Geoff Strang, who farm near Exeter, wanted their new Kinze 3600TR planter to plant two corn […] Read more
