Weed management is a part of crop production that never leaves a grower’s mind. Weeds are constantly evolving and changing; weeds that pop up this year may not have even been a blip on the radar in previous seasons. Adding to this, new forms of resistance are constantly emerging, and decisions can become overwhelming.

To simplify the decision-making process, we’re pleased to bring you another edition of our annual Weed Control Guide, in which we’ve listed products available to you (as of publication time) in alphabetical order. The information herein primarily comes directly from chemical companies themselves. However, growers should always double-check provincial guidelines and product labels to avoid errors.

Furthermore, the ratings provided in the tables should be used as a guide when selecting herbicides. Herbicide-tolerant varieties are listed in red type, and the overall format allows you to compare options for grassy and broadleaf weed products. Once you’ve selected your choices, be sure to compare tank-mixes to best address the range of weeds in your fields. The ratings provided in the tables should be used as a guide when selecting herbicides.

It is important to remember that actual control can vary greatly depending on a number of factors, including soil type, moisture conditions, weed pressure and size, and environment. Also, products can sometimes become antagonistic and will therefore be less effective on a particular weed when used in combination, compared to when it’s used separately. Each year, new products are introduced to the market while others are withdrawn. We have done our best to include all registered products in this guide, but as new products are introduced, we recommend readers make notes in their copy.
