Mexico open to deal with U.S. on GMO corn

U.S. corn growers seek clarity over ban

Reading Time: 2 minutes Mexico City | Reuters — Mexican President Andres Manuel Lopez Obrador said on Tuesday he is seeking a deal with Washington after the United States threatened legal action over Mexico’s plan to ban genetically modified (GMO) corn in 2024. After meeting with Mexican officials on Monday, U.S. Secretary of Agriculture Tom Vilsack said Mexico’s decree […] Read more

Brazil moves closer to China corn exports as Beijing approves traders

Reading Time: 2 minutes Beijing/Sao Paulo | Reuters – Chinese customs updated its list of approved Brazilian corn exporters on Wednesday, a move a Brazilian agriculture official said could jumpstart sales of corn to the world’s second-largest economy. The approvals could reshape global trade flows and result in fewer sales for farmers in the United States, the world’s top corn supplier. […] Read more

U.S. corn farmers wary of vomitoxin, latest stress on global grain supplies

Reading Time: 2 minutes Chicago | Reuters – A fungus that causes “vomitoxin” has been found in some U.S. corn harvested this fall, causing headaches for growers and livestock producers and forcing ethanol plants and grain elevators to scrutinize grain deliveries. The situation is another hit to global grain supplies that have sunk to the lowest in a decade since Russia […] Read more

At 11 on-farm locations across Manitoba in 2020, only four sites showed a statistically significant yield difference.

Split N fertilizer application a good option

Manitoba corn trials suggest it’s not a yield booster, but it can be a yield maintainer

Reading Time: 6 minutes The verdict is out on split nitrogen applications in Manitoba corn. After years of small-plot and on-farm field-scale trials, it appears that split N can provide some flexibility for farmers to adapt to conditions as the season unfolds but, generally, they should only expect the practice to maintain yield, not increase it.  “For many people, […] Read more

Feed weekly outlook: Corn imports pressure grain prices in Lethbridge

Reading Time: 2 minutes MarketsFarm — With harvesting operations winding down, high-delivered bids for feed barley and wheat in Alberta are higher compared to the same time last month and last year. However, there is still some volatility in feed grain prices, according to one Lethbridge-based trader. “I think most (of the increase) was (due to) demand, but as […] Read more

While corn is generally more sensitive to yield loss from weeds, soybeans are more sensitive to Canada fleabane. In field trials, Peter Sikkema found the average yield loss in soybean to be 61 per cent versus 52 per cent in corn.

The Canada fleabane problem

At current corn and soybean prices, the value of control is at an all-time high

Reading Time: 4 minutes If you think you’ve heard the same message about glyphosate-resistant Canada fleabane more than once, you’re probably right. But that doesn’t mean you should pay less attention, especially since it’s particularly important if you’re growing corn. The problem of resistant biotypes isn’t getting much better, says Peter Sikkema, weed scientist with University of Guelph’s Ridgetown […] Read more


Finding new uses for corn and its byproducts is one way to encourage continued production of corn (and soybeans).

Are corn and soybeans on the wane?

Could other crops erode their dominance in Eastern Canada, and if so, which ones?

Reading Time: 5 minutes In the next 10 to 30 years, could corn and soybeans became lesser crops in Ontario and Eastern Canada? What would that look like and how might that unfold?  Before you say, “It’ll never happen,” think back to 1992 and changes such as transgenics, GPS and precision ag technologies and production capabilities that have virtually […] Read more

Mike Cornelissen has been has upgraded his equipment three times as manufacturers have rolled out new designs.

Strip till catching on 

Residue management and improved soil health are among the benefits

Reading Time: 4 minutes In theory, strip till should boost yields, especially in corn, where the practice is most usually used. Clearing residue from a seed zone and berming the soil so it warms faster in preparation for spring planting sounds like an obvious benefit. More equipment manufacturers have adapted systems to enable “multitasking” such as combining strip till […] Read more


The RNAi trait in SmartStax Pro prevents the production of a specific protein in CRW, without which it can’t survive.

A new trait for corn rootworm

The RNAi trait will launch in Canada in 2023 and complement current Bt Cry protein traits

Reading Time: 5 minutes Late in 2019, agronomists in mid-western Ontario urged producers to opt out of growing continuous corn or corn on corn in an effort to break the cycle of resistance that had developed within corn rootworm. The issue had arisen because of resistance to three of four Bt Cry proteins, reducing the effective modes of action […] Read more

#CropPatrol: Corn seen to be very sensitive to weed interference

Reading Time: 2 minutes Ontario farmers grow most of the corn produced in Canada, with 2.2 million acres produced in 2020, a value of more than $2 billion. However, the crop is sensitive to early weed interference. The Weed Science Society of America (WSSA) reported an average corn yield loss of 50 per cent if weeds are left uncontrolled. […] Read more
