Sumitomo Excel Mera 71 Herbicide is a non-selective, post-emergence systemic herbicide containing Ammonium Salt of Glyphosate 71% SG. It is useful for managing a broad spectrum of weeds in tea, non-cropped areas and directed-spray plantation inter-rows when used as per product label recommendation.
Excel Mera 71 works by moving inside the weed plant after absorption through green foliage. It helps control annual and perennial grassy weeds, sedges and broadleaf weeds by inhibiting the EPSPS enzyme, which disrupts essential amino acid synthesis and gradually leads to complete weed control under proper application practices.
Sumitomo Excel Mera 71 is suitable for directed foliar spray where non-selective weed control is required. It should be sprayed directly on actively growing weeds while avoiding contact with crop foliage, as it can damage any green plant part it touches.

Sumitomo Excel Mera 71 Herbicide works by inhibiting the EPSPS enzyme in weeds. This blocks the synthesis of essential aromatic amino acids, disrupting normal plant metabolism and gradually leading to weed control. Because it is systemic, it moves inside the weed plant and helps control weeds from leaves to roots when applied on actively growing green foliage.

Its Ammonium Salt of Glyphosate 71% SG formulation supports broad-spectrum control of grassy weeds, sedges and broadleaf weeds when applied at the recommended dose and weed stage.
