Guidelines for effective and responsible application.

Mode of Action

Glyphosate is absorbed through leaves within 1–6 hours, moving bidirectionally via the phloem. It accumulates in growing points, causing gradual chlorosis and plant death within 1–4 weeks. Glyphosate targets a specific site in the Shikimic acid pathway, inhibiting the production of essential amino acids (phenylalanine, tryptophan, and tyrosine). This disrupts protein synthesis, leading to plant starvation. The process is temperature-dependent, affecting the speed of action.

Environmentally Friendly

This pathway exists only in plants; mammals, birds, fish, and insects must obtain these amino acids from food and do not metabolize glyphosate, contributing to its favourable environmental profile. No other herbicide class targets this site (HRAC group G).

Glyphosate Formulations

Not all glyphosate products are the same. While they share the active ingredient, formulation impacts performance. Since Roundup’s launch, our chemists have developed advanced formulations for improved weed control, less restrictive use, and enhanced safety. Modern Roundup formulations ensure superior uptake, faster action, better rain resistance, and higher efficacy.
