Chemical properties and systemic mode of action
- Active ingredient: Ammonium Salt of Glyphosate 71% SG (organophosphorus glycine class, HRAC/WSSA Group 9).
- Mode of action: Specifically inhibits the 5-enolpyruvylshikimate-3-phosphate (EPSP) synthase enzyme in the shikimic acid pathway, halting aromatic amino acid synthesis.
- Deep systemic translocation: Absorbed through green foliage and translocates basipetally into roots, rhizomes, and stolons, preventing regrowth.
- Soil inactivation: Inactivates rapidly upon contact with mineral soil particles and clays, leaving no residual soil herbicide activity.
Target weed spectrum and approved application areas
- Weed spectrum: Eradicates deep-rooted perennial grasses like Cynodon dactylon (doob grass), Cyperus rotundus (motha), and Saccharum spontaneum (kans).
- Plantation crops: Used in tea estates and fruit orchards with protective spray hoods to prevent herbicide drift onto crop leaves or green bark.
- Non-crop land: Ideal for clearing irrigation channels, field bunds, farm roads, industrial sites, and fallow field preparation.
- Application stage: Most effective when weeds are actively growing with lush green foliage and adequate soil moisture.
Government regulations, drift protection, and safety
- Government guidelines: Follow Central and State Government notifications regarding glyphosate application through authorized Pest Control Operators (PCOs) where applicable.
- Drift guard requirement: Always use a protective spray hood over the nozzle to prevent spray droplets from touching crop foliage.
- Water quality: Dissolve in clean, silt-free water; muddy or turbid water binds glyphosate and drastically reduces herbicide potency.
- Safety instructions: Wear rubber boots, gloves, goggles, and a chemical face mask; observe strict storage guidelines.

Common questions
What is the active chemical in Mira 71 herbicide?
Mira 71 contains Ammonium Salt of Glyphosate 71% SG, a systemic non-selective herbicide.
Is Mira 71 selective or non-selective?
It is a non-selective herbicide that kills all green vegetation it contacts; it must not contact main crop leaves.
How does Glyphosate translocate inside weeds?
It is absorbed by foliage and translocates throughout the plant down to deep roots and rhizomes to prevent resprouting.
Why does muddy water reduce Glyphosate effectiveness?
Glyphosate molecules bind strongly to soil and silt particles in muddy water, inactivating the chemical before it hits the weed.
