Active Ingredient and Translocation Mechanism
Mera 71 contains ammonium salt of Glyphosate formulated as high-concentration soluble granules.
Upon foliar absorption, the chemical travels systemically through weed vascular phloem to underground rhizomes and storage tubers, stopping EPSP synthase enzyme activity.
- Formulation: 71 percent SG (Soluble Granules)
- Systemic action: Translocates throughout roots and vegetative shoots for complete weed kill
- Fast dissolution: Granules dissolve quickly in clean water without leaving tank residues
Target Weeds and Authorized Use Settings
Mera 71 is engineered to suppress difficult perennial grasses, sedges, and broadleaf weeds in authorized non-crop areas and tea plantations.
Because it lacks residual activity in soil, it clears unwanted field vegetation ahead of new planting operations.
- Perennial weeds: Effectively controls Cynodon dactylon, Cyperus rotundus, and Imperata cylindrica
- Application timing: Spray when target weeds have lush green leaves and are actively photosynthesizing
- Regulatory scope: Registered for weed control in tea crops and non-cropped industrial areas under national guidelines
Purchasing, Packaging, and Operator Safety
Commercial packs are commonly distributed in convenient single-dose sachets and larger multi-kilogram containers.
Spray operators must use low-pressure floodjet or flat fan nozzles with protective drift shields to avoid harming adjacent crops.
- Water source: Use clean pond or tap water free from suspended mud and organic sediments
- Personal protection: Wear protective rubber gloves, mask, and safety goggles during preparation and spraying
- Post-application interval: Allow sufficient drying time before rainfall to ensure full systemic uptake

Common questions
What is the technical formulation of Mera 71?
Mera 71 contains Glyphosate 71% SG (Ammonium Salt), formulated as highly soluble dry granules.
How does Mera 71 prevent weed regrowth?
It translocates systemically down into roots, rhizomes, and stolons, destroying the entire root system to prevent regrowth.
Is Mera 71 selective for standing crops?
No, Mera 71 is non-selective and will damage any green crop foliage it touches; use drift shields in non-crop areas.
