Prosedge 750DF Nutgrass Killer

ProSedge 750 DF – Selective Nutgrass & Mullumbimby Couch Control

Target the weeds your mower can’t reach.
ProSedge 750 DF is a selective post-emergent herbicide designed to control Nutgrass (Cyperus rotundus) and Mullumbimby Couch (Cyperus brevifolius) without harming your lawn. Trusted by professionals, it’s powered by Halosulfuron-methyl (750 g/kg) and delivers precise, long-lasting control in both domestic and commercial turf.

Unlike contact herbicides, ProSedge works from the inside out — moving through the weed’s system to stop growth and destroy underground tubers. You’ll see yellowing within 7–10 days and complete control within 4–6 weeks.

How much to apply:
Use 1.3 g per 100 m² mixed in 10 L of water (or 65–130 g/ha) depending on weed density.
Apply evenly over actively growing weeds — at least 5 cm of new leaf growth for Nutgrass or 2 cm for Mullumbimby Couch.
Water lightly after 24 hours, and delay mowing for 2 days post-application for best results.

ProSedge is safe on Couch, Kikuyu, Buffalo, Zoysia, Ryegrass, Fescue, Bentgrass, Carpetgrass, and Queensland Blue Couch when used as directed.
