Wintergrass Killer Herbicide

Wintergrass weed is a grassy cool season annual with perennial and biennial bio-types observed in some regions. It is light green in colour with a tufted growth habit and a white panicle inflorescence germinating from late winter throughout spring and summer. Leaf blades possess a folded venation with a long ligule and boat-shaped leaf tips that curl up at the ends. Looks somewhat similar to Nutgrass.

This particular weed is highly adaptive and can thrive in shaded areas and full sun depending on moisture conditions. Tolerates low mowing heights and can persist in golf greens all year round. Plants reach maturity quickly and seed profusely making them an aggressive weed that can be difficult to control.
