Active ingredient and systemic mode of action
Glyphosate inhibits the EPSPS (5-enolpyruvylshikimate-3-phosphate synthase) enzyme in the shikimate metabolic pathway, which is essential for synthesizing aromatic amino acids (phenylalanine, tyrosine, and tryptophan) in plants. Translocated via phloem to growing meristems and root systems, it kills underground rhizomes and roots.
- Active ingredient: Glyphosate 41% SL (soluble liquid)
- Herbicide group: Organophosphorus glycine derivative (HRAC Group 9)
- Translocation: Symplastic phloem mobility eliminating deep rootstocks and rhizomes
Target weeds and application zones
- Target weeds: Cynodon dactylon (doob grass), Cyperus rotundus (motha), Saccharum spontaneum (kans), and broadleaf weeds.
- Approved use zones: Tea plantations, non-cropped industrial areas, canal banks, and field bunds.
- Fallow land clearing: Applied before land preparation to clear heavily weed-infested wasteland.
Statutory regulations and safety precautions
In India, central regulatory notifications restrict the commercial use of glyphosate strictly to tea crops and non-cropped land through authorized Pest Control Operators (PCOs). Use a protective spray hood to prevent drift onto standing crops, wear chemical-resistant gloves, and avoid application in windy weather.

Common questions
What is the active ingredient in Glycel herbicide?
The active ingredient in Glycel is glyphosate 41% SL, an EPSPS inhibitor systemic herbicide.
Can Glycel be sprayed directly on standing field crops?
No, glyphosate is a non-selective herbicide that will destroy any green crop foliage it touches; it must only be used with protective drift hoods in approved areas.
What are the regulatory restrictions on glyphosate in India?
The Ministry of Agriculture has restricted glyphosate use to tea plantations and non-cropped areas, requiring application by licensed operators.
