Willem van Staveren says perennials and winter annuals such as dandelions, thistle and particularly kochia are targeted in the farm’s fall weed control program.

Weed control timing is important: sooner is better than later

If weeds get the upper hand, a percentage of yield loss can’t be recovered

By Lee Hart April 11, 2023

Willem van Staveren says you can’t beat early weed control. In fact, every year on the family-run southern Saskatchewan farm, the Van Staverens plan for a post-harvest herbicide application to help control winter annual and perennial weeds in preparation for the following growing season. “It is important for us to make the late fall herbicide […] Read more

With the increasing incidence of herbicide resistance, producers must adjust their strategies to manage kochia and other resistant weeds.

Your provincial weed outlook for 2023

Make sure these weeds are on your radar this year

For as long as agriculture has existed in Western Canada, farmers have been waging a battle to control yield-robbing weeds in their fields. It will be a similar story in 2023. The difference this time around is that battle could be shaped largely by the location where it is being fought. While Manitoba received significant […] Read more

As part of a series of weed abundance surveys, 2,277 fields across Saskatchewan were surveyed in 2019 and 2021. That data was used to provide metrics such as the frequency and density with which weed species can occur in a region after post-emergence herbicide application.

Your biggest herbicide-resistant weed threats for 2023 based on the latest survey results

By Jim Timlick April 3, 2023

As any farmer will attest to, herbicide-resistant weeds are a growing concern on the Canadian Prairies. In fact, it’s estimated they cost farmers in Western Canada as much as $530 million annually in lost yields and alternative weed management practices. Charles Geddes, a research scientist with Agriculture and Agri-Food Canada (AAFC), who specializes in weed […] Read more

Rising herbicide resistance means it’s time to broaden your weed control arsenal with chemical, mechanical and non-chemical methods

By Mark Halsall March 27, 2023

Herbicides have long been the go-to solution for Prairie grain producers fighting weed infestations. Over time, it has led to widespread resistance development in many weed species and a shrinking list of chemical options for controlling pervasive weeds like kochia and wild oats that have become resistant to multiple modes of action in recent years.

Q: How can I improve weed control in my crops? A: There is a constant demand to improve overall weed control in our crops. Pre-seed herbicides are the initial application providing the base for that growing season. Growers battle change across the weed spectrum combined with the challenge of weed resistance management. Producers often ask, […] Read more

If your cropland is presently clubroot-free, keep it that way. Do not allow any mud-carrying equipment of any kind on your cropland other than your own farm equipment. Plant resistant varieties and keep the land clubroot-free to enhance your financial future.
