Aquatic Weed Spraying for Submerged Weeds in Ontario

We spray so you can play:

For 18 years, Peerless Turfcare has provided quality aquatic weed spraying for pond, lake, marinas, canal, exterminations for weeds and aquatic growth.

Coverage Areas:

Our coverage area ranges from the start of St Lawrence Seaway at Cornwall south to Windsor and north to Timmins, and everywhere in between.  Peerless Turfcare uses REWARD which is a very safe, effective and fast acting product.  See “before” and “after” pictures at the bottom of this page.

Annual Permits:

The permit application process needs to start early in the season, as early as January to March so that we can spray in June/July.  Permits must be filled out and an application sent to the MECP and in some cases other agencies for their approval before May. This process can take months to complete.    Spraying CANNOT be done without a permit in hand as it is illegal.

The Trent Severn Waterway Commission (Parks Canada), has their own fees and permits for aquatic weed spraying that go above and beyond the Ministry of Environment, Conservations and Parks (MECP) requirements. This permit may take over 100 days to get, as their requirement list is lengthy. Permits are achievable but take time. The optimum time to spray aquatic pond weeds is in June/July. Permits dictate when we can spray. Permits specify safety requirements post application. Peerless AquaCare tends to double these security conditions.

How it works:

Our product is applied from a boat and sprayed over the surface of the water.  It filters down and kills weeds which die and sink to the bottom.  The product degrades on the bottom of waterbody because it is heavier than water.  The process needs to be repeated annually.

Pond Vegetation Control Phragmites and other Invasives:

Vegetation around ponds can be treated throughout the year.   Many ponds have Phragmites E. Common Reed which is an invasive species.   By permission from the Ministry of Natural Resources and Forestry (MNRF) we can control Phragmites in dry ponds dugouts or roadsides.

How to get started:

There are 3 easy steps in the process. First, you will get a quote from us. The second step is filling out a permit request form, and the final step is a requirement from the Ministry of Environment, Conservations and Parks, which requires your adjacent neighbours to acknowledge they are aware you are having water weed control services.

The whole reason I wanted to be on the lake, was to have fun in the sun with my family.   I can do this now that the weeds are gone.   Thank you so much!   NY, Puslinch ON.
