Glyphosine

Glyphosine is a plant growth regulator used on sugar beet and sugarcane. It inhibits fiber production, causing the plant to divert more dry matter to sucrose storage. of glyphosine were used in the US in 1974. It was first registered in 1972, though now is considered largely obsolete. In other plants, e.g. maize, it causes chlorosis by inhibiting plasmid RNA synthesis. It can be synthesized from chloroacetic acid and N,N-bisamine. Metals form complexes with glyphosine.
Chemically, glyphosine is a tertiary amine, a glycine derivative and a phosphonic acid.
It has been manufactured by CCA Biochemical and Monsanto, and sold under the "Polaris" trademark.
