Glyphosine is an organophosphate plant growth regulator.¹It decreases chlorophyll production in new fronds ofL. gibbawhen used at a concentration of 500 µM.¹Glyphosine has been used as a sugarcane ripener.²It also increases the T cell response to an insulin B chain autoantigenic peptide corresponding to amino acids 9-23 of human insulin (EC₅₀= 70.6 nM) and delays the onset of diabetes in non-obese diabetic (NOD) mice when administered at a dose of 80 mg/kg per day.³
