Sempra Herbicide

Sempra Herbicide - Halosulfuron Methyl 75% WG

Sempra Herbicide is a selective, systemic, post-emergence herbicide containing Halosulfuron Methyl 75% WG, designed for targeted management of difficult sedge weeds, particularly Nut Grass (Motha) / Cyperus rotundus.

It is suitable for recommended crops including sugarcane, maize, and bottle gourd. Sempra works systemically after application and moves within susceptible weeds, interfering with the ALS enzyme pathway required for the production of essential branched-chain amino acids.

For farmers dealing with recurring Motha or Nut Grass infestations, Sempra offers a crop-selective weed management option when used according to the approved label directions.

Its main value is its focus on difficult sedge weeds such as Motha / Cyperus rotundus, rather than being positioned as a general-purpose herbicide for every weed.
