Implementing strategies to stave off herbicide resistance can bring increased costs 
to individual farmers in the short term, while the economic benefits are delayed.

Managing herbicide resistance costs

Farmers considering herbicide resistance strategies are looking at the economics first

By
There are several reasons many farmers haven’t yet adopted herbicide resistance management (HRM) plans. These include a lack of information, the complexity of different management strategies and limited time. But a major reason is still economics. Many farmers worry about the costs of implementing a resistance management plan, especially if they’re uncertain about the potential […] Read more

Blackleg management and agronomy

Agronomy tips... from the field

By
Three main tools go into a successful blackleg management strategy in canola: seed genetics, seed treatment and foliar fungicides. Blackleg genetics, along with seed treatments, can help you get into the season and established while protecting seedlings from blackleg for the first few weeks after seeding. At the two- to six-leaf stage, consider using a […] Read more

Lay the groundwork for a strong soybean season

Agronomy tips... from the field

By
Want to set the stage for a strong soybean crop? Start by seeding into warmer soils. Light tillage can help break up crop residue and spread it evenly across your field. Working up soil also attracts sunlight and heat more effectively. Aim to seed into moisture to give your beans a better start. If possible, […] Read more

Mustard acres feeling squeeze from canola

By
CNS Canada –– Following the largest mustard crop in more than a decade in 2016, supply/demand fundamentals are expected to spur a reduction in Canadian mustard seedings in 2017. However, with more and more cropland moving into canola, mustard acreage increases may be limited in future years when supplies are tight again. After growing the […] Read more

Narrow-leaved hawk’s beard travelling

This noxious weed is spreading outside of northwest Sask. 
and the Alta. border

By
Up until recently, narrow-leaved hawk’s beard was mostly found in northwest Saskatchewan and along the Alberta border. A 2014-15 weed survey has revealed that the weed has spread to areas outside of these traditional hotspots. Identification and control can both be difficult. For this reason, it is advised that growers — especially those who live in non-traditional hotspots — take […] Read more

Controlling cleavers without quinclorac

With quinclorac off of the herbicide menu, farmers will need to use other tools

By
Last spring, the Western Grains Elevator Association (WGEA) and the Canadian Oilseed Processors Association (COPA) advised growers that they would not accept quinclorac-treated canola grown and harvested in 2016. The reason for this announcement was to make sure that grain shipped to customers in other countries remains in compliance with regards to Maximum Residue Limits […] Read more

Back to the agronomy basics in canola

Experts advise growers to focus on quality seed and nitrogen before less conventional inputs

By
Canola growers have been asking agronomists questions about promoted products. Do they work? And if so, are they worth the additional cost? Two researchers, Murray Hartman, oilseed specialist with Alberta Agriculture and Forestry, and Neil Harker, research scientist, weed ecology and crop management, Agriculture and Agri-Food Canada, conducted a study to test the inputs that […] Read more

Are there resistant weeds in your fields?

The answer to this question is probably yes. Testing can give you a definite answer

By
Every season more farmers face the challenge of herbicide-resistant weeds. “Herbicide resistance is the genetic capacity of a weed population to survive a herbicide treatment that, under normal use conditions, would effectively control that weed population,” said Dr. Jeanette Gaultier, weed specialist with Manitoba Agriculture. It’s sometimes described as evolution happening at an accelerated pace […] Read more

Spraying your fungicide in “the zone”

With Bayer’s new “Zone Spray,” farmers can skip the fungicide in some parts of the field

If Warren Bills has his way, farmers will have a better way to forecast sclerotinia than the old wet boots and weather test. “We believe there is a better way to manage the risk of that disease and the returns growers get when they spray,” Bills told agronomists and industry at Bayer’s Ag Summit in […] Read more

Old, new products deliver multi-modes of action

The challenge is to hit weeds with two or more active ingredients to reduce resistance

By
Old chemistry, new formulations, multiple modes of action — these are all elements farmers can include in their weed control toolbox heading into 2017, say weed researchers and crop protection specialists. One of the most important elements these days for either preventing or managing herbicide resistance in weeds is to approach control with multiple modes […] Read more
