Habitat Aqua

Habitat Aqua Herbicide

Habitat® Aqua provides effective, long-lasting, post-emergent control of invasive and undesirable vegetation in and around aquatic sites. Habitat Aqua may be used in directed applications for control of invasive plants in naturalized areas, including privately owned, provincial, federal or other public lands and parks.

How It Works


Habitat Aqua is readily absorbed through foliage and rapidly translocated throughout the plant. Treated plants stop growing shortly after an application. Chlorosis appears first in the newest leaves, and necrosis spreads from this point.


In perennials, Habitat Aqua translocates into underground or submerged storage organs to control weeds and prevent regrowth. Chlorosis and tissue necrosis may not be apparent until the season following an application.


Apply Habitat Aqua to emergent foliage of the target vegetation, using care to avoid over-application or run-off that might result in an inadvertent application directly to water. Habitat Aqua does not control plants that are completely submerged or have a majority of foliage under water.


The application of Habitat Aqua requires Aquasurf® non-ionic spray adjuvant or another non-ionic surfactant. When making aquatic applications, these applications must be made with Aquasurf.


Weeds Controlled
