Production Methods
Glyphosate-sesquisodium is produced by first manufacturing technical-grade glyphosate through the standard industrial route, typically the glycine/IDA-based pathway in which glycine (or its substituted precursor) is phosphonomethylated and then neutralised to yield glyphosate acid. Once the acid is purified, producers convert it into the sesquisodium form through controlled partial neutralisation with sodium hydroxide, adding 1.5 molar equivalents of sodium so that the product contains both mono- and disodium glyphosate species in the stable “sesquisalt” ratio. This neutralisation is carried out in aqueous media under carefully managed pH and temperature to prevent salt instability or formation of insoluble by products.
Mechanism of action
Broad-spectrum, systemic, contact action, translocated and non-residual acivity. Inhibits EPSP synthase.
