Oryzalin 500 is a unique pre-emergent herbicide, which is applied to the soil or surface to selectively control Winter Grass, Annual Rye Grass, Crab Grass and Chickweed in turf situations. Oryzalin also inhibits root growth in certain small seeded broadleaf weds and will bind strongly to soil colloids so it is unlikely to leach or move.
Specticle Herbicide is a new and innovative pre-emergent herbicide for warm-season turf. Long residual control - up to 8 months. Non staining and no odour.
