Glyphosate resistant Canada fleabane has been confirmed in 28 counties throughout the province. Some counties also have multiple resistant Canada fleabane which is resistant to both glyphosate and ALS or group 2 herbicides. It is finding its way from fields of corn, soybeans and wheat into orchards and vineyards at an amazing rate. Therefore, we need to know what we can do to control what is there to prevent the further spread of this multiple resistant weed.
