We use two herbicides for treatment:
For dry sites – Roundup WeatherPRO is used. This is a herbicide used regularly by the agricultural community.
For wet sites – Roundup Custom is used. We have a special permit to use this in the Long Point region. “Custom” is essentially the same as WeatherPRO except that all the pre-added surfactants (that make the product stick to the plant) are removed. The surfactants are the portion of the product that can be harmful to aquatic life. We use a water safe surfactant approved for aquatic use that is added to Roundup Custom at the time of application to ensure our treatment is effective.
Habitat Aqua, an imazapyr-based herbicide, has recently been registered for control of invasive Phragmites in Canada in and around aquatic sites. The LPPAA is currently investigating the use of this product as part of our control program.
