Will relay intercropping work in Ontario?

RealAgriculture agronomist Peter Johnson is keeping a close eye on relay intercropping trials planted in Ontario this summer. The objective of the research is to evaluate whether Ontario farmers could effectively plant soybeans into standing wheat versus double cropping soybeans that are planted after wheat is harvested. In this video, Johnson inspects an intercropping trial at… Read more »

Chaff deck designed to capture and control weed seeds in combine wheel tracks

Every year at harvest, weed seeds are spread across the field through the back of most combines, setting the stage for weed competition across the entire field. A company in Western Australia has developed a tool to confine those weed seeds to the combine’s wheel tracks. The EMAR Chaff Deck replaces the chaff spreader on… Read more »

Corn School: Will drone sprayers fit your farm?

Is the clock ticking on the future of your ground sprayer? Could it eventually be replaced by a swarm of UAV sprayers that could better target weeds and deliver herbicide to exact locations in the field? These are questions we explore with AGRIS Co-operative agronomist Dale Cowan on this episode of RealAgriculture’s Corn School. Cowan recently… Read more »

Soybean School: Why tackle herbicide resistance with multiple modes of action?

Many agronomists talk about the importance of multiple modes of action when planning a weed control program. In this episode of RealAgriculture’s Soybean School, Ontario Ministry of Agriculture, Food and Rural Affairs weed specialist Mike Cowbrough shows you why. We catch up with Cowbrough as he surveys a patch of Canada fleabane that has survived… Read more »

Soybean School: Scout to evaluate your stand and when to go rolling

What’s your strategy when scouting a newly emerged soybean field? When Agromart Group agronomist Steph Kowalski walks into a soybean field this time of year, the first thing she looks to assess is final emergence and population. “It’s important to know how well we got that seed into the ground,” Kowalski tells RealAgriculture’s Bernard Tobin… Read more »

TechTour: Culti Cam system offers automatic cultivator positioning in row crops

In another move towards automation, Claas has unveiled a system for automatic steering of cultivators in row crops. The Culti Cam uses a high-resolution camera to detect rows, and then adjusts the position of the implement, centring it between rows, independent from the tractor’s steering. Using colour and 3D surface information, Claas says the camera software… Read more »

Group 14 resistant waterhemp confirmed in Ontario

It’s not necessarily the happiest of discoveries, but it’s a first-of-its-kind discovery, nonetheless. Work out of the University of Guelph has confirmed Group 14 resistance in waterhemp at multiple locations in Ontario. What’s more, Dr. Peter Sikkema’s research team, including graduate student Lauren Benoit, has also confirmed waterhemp with cross-resistance to Groups 2, 5, and… Read more »

Canola School: Lessons learned about weed seed destruction machines

With increasing cases of herbicide resistance, machines designed to destroy weed seeds at harvest could be a valuable tool. But like any technology that is not yet widely adopted, there are also some lessons to be learned and challenges to overcome, as researchers with Agriculture and Agri-Food Canada confirmed last year. 2017 marked the first… Read more »

Soybean School: Mind your fencerows to reduce weed resistance

Are we doing enough to reduce the herbicide-resistance weed seedbank on Ontario farms? That’s a question AGRIS Co-operative agronomist Dale Cowan wants farmers in the province to consider when they’re planning their weed control programs for this year. Cowan recently attended the Commodity Classic in Anaheim, California, where he talked with farmers from Mississippi who… Read more »

What’s new for herbicides in Ontario for 2018

Planting is just around the corner, and if you’re in full-on crop planning mode you’re likely curious about what’s new, what’s old, what’s repackaged, what’s the best bet for herbicides in 2018. Lucky for you, Ontario Ministry of Agriculture, Food and Rural Affairs weed management specialist Mike Cowbrough faces an avalanche of these questions every… Read more »

Take a closer look – it may be waterhemp

Waterhemp has set down roots across Ontario, from Essex and Lambton County, and reports indicate it may have migrated as far east as Quebec. Controlling the invader poses several challenges for growers, says BASF agronomist Richard Anderson. The first problem is a high level of herbicide resistance. Some waterhemp is resistant to up to three… Read more »

Soybean School: How wide is your spring burndown window?

If you have weeds pop up prior to planting soybeans you can control them with a burndown herbicide application. But what happens when rain and wind conspire to prevent you from applying a burndown and you have to control weeds after planting? In this episode of the Soybean School, OMAFRA weed control specialist Mike Cowbrough… Read more »

John Deere unveils guidance system opening up autonomous tillage in row crops

Developed by John Deere and subsidiary Monosem, the AutoTrac Implement Guidance system unveiled at Agritechnica in Germany this year gives farmers the opportunity to mechanically target weeds in row crops, at high speed. The system involves two StarFire satellite receivers (one on the tractor and one on the implement), as well as an AutoTrac vision… Read more »

Soybean School: Ontario growers better positioned to manage dicamba

In 2017, many U.S. growers struggled to manage dicamba use with increasing acres of dicamba-tolerant Xtend soybeans. The dicamba story in Ontario, however, was much different, as growers had few issues with managing the marriage of the herbicide and the new trait. In this edition of RealAgriculture Soybean School, OMAFRA weed specialist Mike Cowbrough explains… Read more »

The future is now for farm satellite technology

From automated tractors to precision sprayers that spray only weeds, new technology is creating a buzz in the farming community. But let’s not forget about satellite technology, which is now poised to make a tremendous impact on crop production. That’s the message Patrick Crampton from Farmers Edge shared during a technology discussion panel at the recent… Read more »
