Polaris Weed Killer Herbicide

Usually Ships in 1-2 days
Polaris herbicide does what many other herbicides fail to do: deliver quality results against annual and perennial grasses. It not only targets tough grass species but also various broadleaf weeds, brush and vines. In addition, Polaris kills numerous aquatic weeds near lakes, rivers and streams. It has an active ingredient that provides long-term effectiveness and prevents you from having to retreat the area several times per year. For the control of undesirable vegetation, nothing works quite like Polaris herbicide.

How Polaris Herbicide Works

For severe weed growth, avoid retreating the area for at least two weeks.
