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 »

European Commission gives glyphosate a new 5-year licence

The European Commission has granted a new five-year licence for glyphosate, with Germany breaking a stalemate that would have seen the herbicide de-authorized in less than three weeks. After falling short of the qualified majority needed for glyphosate’s renewal earlier this fall, an appeals committee approved a five-year licence on Monday, with 18 countries voting… Read more »

This robot kills weeds with lasers

A robot that zaps unwanted organisms with lasers may describe a character in a science fiction plot, but in reality, it’s a technological response to farming with high labour costs. The Jäti is a battery-powered autonomous crawler built by a pair of German companies that is designed to identify weeds and destroy them with laser… Read more »

Growing food soybean demand fueling Sevita

What will the identity preserved (IP) soybean market look like in 10 years? Sevita International’s new CEO Don Rees believes the market will double over the next decade and he feels that’s a conservative estimate. Grabbing a larger piece of that growing IP pie will be one of Rees’ goals as he takes the reins… Read more »

New residual herbicide tackles resistant weeds

Canadian corn and soybean growers have a new tool to tackle resistant and tough-to-control weeds. Zidua SC, a new Group 15 herbicide from BASF, will be available in 2018. Deven Esqueda, BASF corn and soybeans crop manager, says the herbicide is labelled for use in herbicide-tolerant soybeans and field corn. With the active ingredient pyroxasulfone,… Read more »

Soybean School: Pre + post = successful IP weed control

What’s the best herbicide program for food-grade, non-GMO, identity preserved soybeans? It’s a common question OMAFRA weed specialist Mike Cowbrough gets from growers and we have the answer on this edition of RealAgriculture Soybean School. Cowbrough says there’s no magical herbicide that can handle all the challenges food-grade soybeans face during the growing season. But… Read more »

Knowing your variety helps avoid ‘gnarly barley’

Cereal variety trials typically give researchers great insight into yield, disease tolerance, standability and a host of management considerations to help growers pick the right variety for their fields. In this year’s Ontario Spring Cereal Performance Trials, researchers are also getting a good look at the impact herbicide choices can have on cereals. In this… Read more »

Soybean School: One-pass vs. two-pass weed control

Should you spray your soybeans once or twice? In this episode of Real Agriculture Soybean School, OMAFRA weed specialist Mike Cowbrough takes a look at how one-pass and two-pass herbicide systems compare. He notes that a one-pass program can offer effective weed control if growers keep soybeans fields weed-free through the third trifoliate stage. But… Read more »

Watch for these weedy invaders in Ontario

You’ve probably seen and heard reports of the impact invasive weeds like waterhemp and palmer amaranth could have on Ontario crops. While these two heavyweights tend to capture the headlines, there’s a host of other invaders also looking to find a home in your fields. At the recent Southwest Crop Diagnostic Day, Ridgetown College, University… Read more »

Wheat School: Unleashing a bacteria biopesticide to control grassy weeds

A “biopesticide” is defined as a living organism that’s capable of controlling a pest, including weeds. Dr. Susan Boyetchko, research scientist with Agriculture and Agri-Food Canada in Saskatoon, specializes in biopesticide technology, and she’s been working on a program to develop bio-based tools for controlling grassy weeds, such as wild oats and green foxtail. As she explains… Read more »

Wheat School: How harvest weed seed control could fit in the fight against herbicide resistance

Harvest weed seed control has been widely adopted in Australia as a tool in fighting herbicide resistance. When it comes to North America, farmers in southern States, such as Arkansas, have started implementing these concepts, but the idea of destroying weed seed viability has yet to take off here in Canada. In this Wheat School episode,… Read more »
