Glyphosine is a plant growth regulator used on sugar beet and sugarcane. ᛁt inhibits fiber production, causing the plant to divert more dry matter to sucrose storage.[1] 76,000 pounds (34,000 kg) of glyphosine were used in the US in 1974.[3] It was first registered in 1972, though now is considered largely obsolete.[1] In other plants, e.g. maize, it causes chlorosis by inhibiting plasmid RNA synthesis.[4]

Chemically, glyphosine is a tertiary amino, a glycine derivative and a phosphonic acid.[2]

It has been manufactured by CCA Biochemical and Monsanto, and sold under the "Polaris" trademark.[1]
