Do you want to stay up-to-date on where herbicide resistant weeds have been identified in Ontario? Field Crop News can help with a searchable Master table of all herbicide resistant weed species in Ontario by County and Herbicide Group (confirmed by the University of Guelph). The post also features distribution maps (by county and herbicide group) of resistant weed species.
Here are a couple of examples of search results, the first simply typing in a county.
The second example searches for a county and for part of the name of the weed, allowing us to see results for both giant ragweed and common ragweed.
Jump over to Field Crop News to browse the maps and database for yourself.
