Managing herbicide resistance

Gowan Canada will host a speaker series 
on Wednesday and Thursday at Ag in Motion

By
Diversity is defined in the dictionary as “the condition of having or being composed of differing elements.” In weed control, diversity means using multiple strategies, or an integrated weed management approach. For herbicides, this means using all of the modes of action available to reduce the risk of weed resistance. This may be obvious, but […] Read more

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

Start planning spring crop rotations

Strong crop rotations can bring along a wealth of long-term agronomic benefits

By
Crop rotations can be used to take advantage of differences in how each crop in a rotation contributes to increased soil organic matter, aids in pest management, manages soil nutrients and controls soil erosion. Rotating different crops in the same field can effectively promote sustainable crop production. If you haven’t already started planning your crops […] Read more

The latest in using integrated weed management tools for hard-to-manage weeds

By
A three-year study in Arkansas has found that a combination of fall management practices and herbicide use are the most effective ways to control herbicide-resistant Palmer amaranth, when combined with a herbicide program. But Arkansas isn’t Alberta. So what can western Canadian farmers learn from this study? More and more often the message in weed […] Read more

Stem Shock: new herbicide in development

A new mode of action based on RNA could soon be killing a weed near you

By
It’s been over 20 years since chemical companies released a new mode of action in herbicides. But a B.C.-based company is cooking up a whole new type of herbicide. “We use a different mode of action for the actual killing of the plants than a lot of traditional herbicides. Most herbicides, by reducing the specific […] Read more
