Active technical content and systemic mode of action
Glycel contains Glyphosate formulated as an isopropylamine salt (HRAC Group 9).
Key technical properties:
- Active composition: Glyphosate 41% Soluble Liquid (SL) (equivalent to 360 g/L glyphosate acid).
- EPSP synthase inhibition: Inhibits 5-enolpyruvylshikimate-3-phosphate synthase, halting synthesis of essential aromatic amino acids (phenylalanine, tyrosine, tryptophan).
- Systemic basipetal translocation: Absorbed through green foliage and translocated downward through the phloem into subterranean rhizomes, tubers, and stolons.
- Complete weed eradication: Deep-rooted perennial grasses and sedges turn yellow within 7 to 10 days, followed by complete root and foliar death within 2 to 3 weeks.
- Soil inactivation: Inactivated upon contact with soil particles through strong microbial binding and degradation, leaving no residual soil activity.
Target weeds and approved operational areas
Glycel provides broad-spectrum suppression of difficult perennial and annual weed complexes:
Primary target weeds and use areas:
- Tea estates: Directed inter-row spraying between tea bushes using hooded nozzles without contacting green foliage.
- Non-crop agricultural land: Eradication of perennial brush and grasses along fence lines, bunds, and irrigation canals.
- Grasses and sedges controlled: Cynodon dactylon (Bermuda grass), Cyperus rotundus (purple nutsedge), and Imperata cylindrica (cogon grass).
- Broadleaf weeds controlled: Parthenium hysterophorus, Commelina benghalensis, and Ageratum conyzoides.
Dose guidelines, pricing factors and safety rules
Dilute Glycel according to CIBRC-approved product label rates (typically 800 ml to 1.2 litres per acre in 150 to 200 litres of clean water).

Always wear personal protective equipment, avoid spraying in windy conditions or near standing food crops, and never spray near water bodies.

Common questions
What is the active technical ingredient in Glycel herbicide?
Glycel contains Glyphosate 41% SL, a systemic non-selective herbicide.
Why does Glycel destroy deep-rooted perennial weeds completely?
It translocates systemically through the phloem into underground rhizomes and tubers, halting aromatic amino acid synthesis throughout the weed.
What causes variations in Glycel 1-litre retail prices?
Retail prices vary across districts due to state taxes, transportation logistics, and individual dealer promotions.
