WINTER GRASS KILLER

David Grays Winter Grass Killer will selectively control winter grass in home lawns & sports turf.
If left untreated, Winter Grass will quickly spread through your primary lawn when it's in its periods of dormancy around late Autumn, Winter and early spring. The spread of Winter Grass will quickly choke-out your primary lawn inhibiting its ability to grow and flourish.
Pre-emergent winter grass control is achieved through the presence of Propyzamide being active (for up to 8 weeks) in the soil at the time of germination. The mixed product should be applied to the problem area and watered into the root zone with around 10-12mm of irrigation or rainfall.
Post-emergent winter grass control is achieved through applying the chemical directly to areas of winter grass infestation, including the leaf and root zones. The mixed product should be applied to the problem area and watered into the root zone with around 10-12mm of irrigation or rainfall. The propyzamide active will enter the plant systemically through the roots into the plant and will control post emergent winter grass infestations within 2-3 weeks.
