Description and Uses

Glyphosine was introduced in 1973 and is preferably used in sugar beets. The synthesis starting with glycine uses two equivalents of formaldehyde and of phosphorous trichloride under oxidative conditions. A second derivative of Glyphosate is a cyclic phosphaoxazole being formed from Glyphosate and formaldehyde. This compound is claimed to control the growth of some grasses without dis- coloration or phytotoxicity.

Chemical ripener; plant growth regulator.
