Halo-Force 25g – discontinued Alternative is Indigo Prosedge 750 DF 25gm An easy-to-use granular herbicide for the selective control of Nutgrass and Mullumbimby Couch with high turf safety across many varieties. Nutgrass: Apply when new leaf growth is greater than 5cm (usually Spring / Summer). Mullumbimby Couch: Apply when new leaf growth is greater than 2cm (usually Spring / Summer). Apply when weeds are actively growing. Apply follow-up treatments as required if sufficient new growth warrants weed control. Growth is greatest of both weeds following rainfall events. Drought stress after treatment may reduce control. Weed foliage and seed head gradually turns yellow until total desiccation (death) occurs. Initial symptoms appear in 7-10 days with full weed control effects appearing over 4 to 6 weeks.
