Active ingredient chemistry and biochemical mode of action
Glyphosate is an organophosphorus herbicide with non-selective, systemic action that eradicates both annual and deep-rooted perennial weed species.
- Inhibits 5-enolpyruvylshikimate-3-phosphate (EPSP) synthase, disrupting the shikimic acid biosynthetic pathway.
- Blocks synthesis of vital aromatic amino acids (phenylalanine, tyrosine, and tryptophan) essential for plant protein production.
- Readily absorbed by green foliage and translocated through plant phloem down into underground roots, rhizomes, and stolons.
- Shows negligible soil residual activity because it strongly binds to soil clay and organic matter where it undergoes microbial degradation.
Statutory usage restrictions and regulatory framework in India
Government of India notifications place strict statutory limitations on the sale and application of Glyphosate formulations.
- Application is officially approved primarily for tea plantations and designated non-cropped industrial sites.
- Under Ministry of Agriculture notifications, application must be carried out only through certified Pest Control Operators (PCOs).
- Strictly prohibited from use in conventional food grain, pulse, or vegetable fields where drift can cause severe crop death.
- Retail sales are subject to strict record-keeping and dealer licensing oversight by state agriculture departments.
Safety protocols, application practices, and drift mitigation
Applicators must use protective coveralls, chemical-resistant gloves, goggles, and vapor-filtering masks. Spray only during calm weather using low-pressure nozzles fitted with drift-reduction spray hoods. Never allow spray mist to drift onto non-target vegetation, standing agricultural crops, or nearby natural water bodies.

Common questions
What is the active chemical ingredient in Glycel herbicide?
Glycel contains Glyphosate 41% SL (soluble liquid), a broad-spectrum non-selective systemic herbicide.
What are the legal restrictions governing Glyphosate application in India?
Under central statutory notifications, Glyphosate is approved for tea plantations and non-crop areas, restricted to application by licensed pest control operators.
Does Glyphosate leave residual weed control in the soil?
No, Glyphosate strongly adsorbs to soil particles upon contact and is rapidly broken down by soil microbes, providing no residual pre-emergence control.
