Dicamba has been registered in Canada for use against broadleaf weeds for more than a decade. Its chief merit, says Mike Cowbrough, field crop weed specialist for OMAFRA, is its use as a pre-emergence or burndown product against glyphosate-resistant weeds that occur early in the growing season.
Producers have come to recognize the value it brings to a crop protection strategy, particularly when used in a first herbicide pass for early control of weeds like lamb’s quarters, redroot pigweed and common ragweed. But like any good crop protection strategy, knowledge is power, and it’s important to be mindful of details and best practices to maximize the potential of this important tool.
