Invasive Phragmites

The Invasive Phragmites Control Centre (IPCC) and Quinte Conservation are working with the municipalities of The City of Belleville and Prince Edward County to mitigate the spread of Invasive Phragmites in the Quinte Watershed. Starting the week of August 17, 2026, an experienced team team of professional applicators will be applying a pesticide treatment to the Invasive Phragmites colonies listed in the notices below.

Why Control Phragmites?

Invasive Phragmites is an aggressive non-native plant that:
•Reduces native biodiversity.
•Degrades wetlands and wildlife habitat.
•Restricts access to shorelines and waterways.
•Impairs drainage and water movement.
•Creates dense monocultures that displace native vegetation.

Controlling invasive Phragmites supports the restoration of native ecosystems and helps protect the environmental, recreational, and agricultural resources of Prince Edward County.

City of Belleville

The Invasive Phragmites Control Centre (IPCC), Quinte Conservation, and the City of Belleville intend to control invasive European Common Reed (Phragmites australis subsp. australis) within municipal road allowances and other City-owned properties throughout the City of Belleville. Treatments will target established populations of invasive Phragmites identified through the Quinte Region Phragmites Management Area (QRPMA) roadside monitoring program.

Treatment Areas

Treatment sites are located throughout the City of Belleville, including:
•Dundas Street West and Avonlough Road
•Haig Road and Oak Ridge Boulevard area
•Station Street corridor
•Airport Parkway West corridor
•Casey Road
•Cannifton Road
•River Road
•Mudcat Road and Country Charm Drive area
•Millennium Parkway commercial area
•Cloverleaf Drive
•Sidney Street corridor
•Bell Boulevard corridor
•Hannafin Road
•Enterprise Drive
•Wallbridge Loyalist Road corridor
•Moira Street West
•Point Anne Road
•Scuttlehole Road and Bronk Road area
•Bellevue Drive

A complete list of treatment locations is available through Quinte Conservation and the City of Belleville. Treatment areas include both terrestrial and wet roadside habitats. Several sites occur in wetlands, stormwater infrastructure, and drainage features.

Pesticides to be Used

The contractor will use pesticides registered under the Pest Control Products Act (Canada):

Terrestrial (Dry) Sites

VisionMAX Herbicide (PCP Registration No. 27736) / Timberline Herbicide (PCP Registration No. 33456)

Active Ingredient: Glyphosate (present as potassium salt).

Surfactant/Adjuvant: MSO Concentrate with Leci-Tech (PCP Registration No. 28385)

Active Ingredient/Guarantee: Methylated seed oil of soybean 70%.

Aquatic/Wet Sites

Habitat Aqua Herbicide (PCP Registration No. 32374)

Active Ingredient: Imazapyr (present as isopropylamine salt).

Aquasurf Non-Ionic Spray Adjuvant (PCP Registration No. 32152) 

Active Ingredient: Surfactant blend.

These pesticides will be used by licensed applicators to control invasive Phragmites populations in accordance with all federal and provincial regulations. The pesticide use is in accordance with the exception to Ontario's cosmetic pesticide ban under subsection 7.1(2) of the Pesticides Act for the management, protection, establishment, and restoration of natural resources as prescribed in Section 28(1) of Regulation 63/09.

Treatment Timing

Applications are expected to commence the week of August 17, 2026, weather permitting, and conclude by the end of the week. Treatment dates may vary depending on site conditions and weather.

Prince Edward County

The Invasive Phragmites Control Centre (IPCC), Quinte Conservation, and Prince Edward County intend to control invasive European Common Reed (Phragmites australis subsp. australis) within municipal road allowances and other County-owned properties throughout Prince Edward County. Treatments will target established populations of invasive Phragmites identified through the Quinte Region Phragmites Management Area (QRPMA) roadside monitoring program.

Treatment Areas

Treatment sites are located throughout Prince Edward County, including:

•County Road 2 corridor
•County Road 3 corridor
•County Road 4 corridor
•County Road 5 corridor
•County Road 10 corridor
•County Road 19 corridor
•County Road 23 corridor

•Marsh Road
•Bakker Road
•Gardenville Road
•Harbard Road
•Vienna Road
•Oram Road
•Ridge Road
•Miller Road

Invasive Phragmites (Phragmites australis) is an aggressive invasive plant hat spreads quickly and out-competes native species for water and nutrients. It is not clear how it was transported to North America from its native home in Eurasia.

It has been causing damage to Ontario's biodiversity for decades by releasing biochemicals from its roots into the soil to hinder the growth of surrounding plants. 

Compared to its native counterpart, Invasive Phragmites can grow in dense stands with as many as 200 stems per square metre, and reach heights up to 15 feet. It's stems are tan/beige in colour with blue-green leaves and large, dense seedheads. Native Phragmites have reddish-brown stems, yellow-green leaves and smaller, sparser seedheads.

  • Crowds out native vegetation, resulting in decreased plant biodiversity
  • Provides poor habitat and food supplies for wildlife, including several species at risk
  • Grows very quickly, causing lower water levels as water is transpired faster than it would be with native vegetation
  • Increases fire hazards as stands are composed of a high percentage of dead stalks
  • Affects agriculture, cause road safety hazards
  • Impacts recreational activities such as swimming, boating, and angling

Quinte Region Phragmites Management Area

Quinte Conservation is in the early stages of developing a Quinte Region Phragmites Management Area (QRPMA) with potential partners, including watershed municipalities, organizations and volunteer-based lake groups.

The QRPMA will support the prevention, control, and eradication efforts to mitigate the threats posed by Phragmites.
