Mira 71 Herbicide: Ammonium Salt of Glyphosate 71% SG

Active Ingredient Chemistry and Systemic Translocation

Mira 71 features highly concentrated water-soluble granules engineered for deep weed kill.

Key biochemical attributes:

• Active ingredient: Ammonium salt of glyphosate formulated at 71% SG concentration.
• EPSP synthase inhibitor: Halts the biosynthesis of essential aromatic amino acids (phenylalanine, tyrosine, tryptophan), stopping plant protein synthesis.
• Deep systemic translocation: Absorbed through foliage and translocated downward through phloem vessels to destroy deep underground rhizomes and tubers.
• Non-selective spectrum: Destroys broadleaf weeds, annual grasses, and deep-rooted perennial sedges indiscriminately upon foliage contact.

Approved Use Areas and CIBRC Regulatory Rules

Central regulatory directives govern the lawful application of glyphosate formulations across India.

Approved use sectors and guidelines:

• Tea plantations: Applied as a directed spray between tea bushes to control dense weed flushes without contacting tea leaves.
• Non-cropped areas: Used along farm fences, irrigation ditch banks, railway corridors, and industrial sites to clear heavy weed overgrowth.
• Regulatory restriction: Government directives mandate that glyphosate formulations must be used exclusively in tea crops and non-crop areas by trained applicators.
• No selective field use: Never spray across standing food crops like wheat, rice, or vegetables, as it causes complete crop destruction.

Application Protocols and Spray Drift Precautions

Preventing accidental spray drift onto valuable crops requires disciplined spraying equipment.

Operational precautions:

• Hooded nozzles: Always use flat fan or floodjet nozzles fitted with protective spray hoods to prevent wind drift onto desirable vegetation.
• Active weed growth: Spray when target weeds are green, actively growing, and have adequate foliage surface to absorb the chemical.
• Clean water requirement: Use clean water free of suspended clay or silt, as soil particles bind and deactivate glyphosate molecules.
• Operator safety: Wear rubber boots, nitrile gloves, protective eyewear, and a respirator during mixing and field application.
