The Ontario Ministry of Natural Resources and Forestry and partners have undertaken one of the first aquatic uses of herbicide to control phragmites in Canada at Rondeau Provincial Park and the results so far appear successful.
The ministry was approved for emergency use of the herbicide at Rondeau and Long Point Provincial Park in 2016 and again earlier this year by Health Canada’s Pest Management Regulatory Agency.
According to a September report from the ministry, this type of treatment was not used in Canada prior to 2016, but it has been used regularly in the U.S. The herbicide can only be used in Canada when permission is granted by the PMRA. Click on the following sentence to access the full story.
“We’ve consulted some U.S.-based experts in some adjacent states who have a long history of control of aquatic infestations of phragmites,” said Michael Irvine, the provincial vegetation management specialist at the ministry.
