Dhanuka Sempra Herbicide – Powerful Control Over Nutgrass in Sugarcane & Maize Fields

If you're a sugarcane or maize grower, you already know the nuisance called Cyperus rotundus (motha or nutgrass). It spreads fast, drains nutrients, and competes with your crop roots — cutting your yield silently. Dhanuka Sempra is your answer to this stubborn weed.

Powered by Halosulfuron Methyl 75% WG, Sempra is a systemic herbicide that moves through the plant and stops the weed at the root — without affecting your main crop. Within 24 hours, it starts showing results. No more digging, no more manual weeding.

Real Farmer Advantage

“Earlier we were doing 2–3 rounds of weeding manually. After using Sempra in our maize field, nutgrass stopped spreading, and yield went up. It saved both time and money.”
– Ramlal Yadav, Maize Farmer – Rewa, MP
