Action against weed resistance

Resistant weed management costs around the world

With an effective integrated weed management plan, Canadian growers can avoid some of the additional costs that US and Australian growers have incurred due to herbicide resistance. Here’s a snapshot:

  • Growers in the US purchased inexpensive glyphosate for years
  • Today, they need to rely on different, more expensive herbicides
  • Some have even incurred an extra $150/acre for hand roguing
  • With no weed control, herbicide resistance included, there is an automatic 30% yield decrease (Joerg Ellmans)
  • Increased management costs and yield loss due to resistant weeds are costing Australian growers on average an additional 27%/acre (Source: 2014/2015 Grains Development Research Corporation)
