Description A user-friendly granular herbicide designed for selective control of Nutgrass and Mullumbimby Couch, offering excellent turf safety across a wide range of turf varieties. Nutgrass: Apply when new leaf growth exceeds 5cm (typically in Spring or Summer). Mullumbimby Couch: Apply when new leaf growth exceeds 2cm (usually Spring or Summer). For best results, apply when weeds are actively growing. Repeat treatments may be necessary if significant new weed growth occurs. Both weeds tend to grow most vigorously after rainfall. Note that drought stress following application can reduce effectiveness. Weed foliage and seed heads will gradually yellow and eventually dry out (desiccate). Initial symptoms appear within 7–10 days, with complete weed control visible over 4 to 6 weeks. Application Rate: 1.3g/100sqm Not required to be watered in after application. 25g Halo-Force can cover up to 1920sqm.
