PHYSICAL CHEMISTRY
glyphosate
Composition Tech. is ³95% pure. Zwitterion structure (P. Knuuttila & H. Knuuttila, Acta Chem. Scand., 1979, 33, 623). Mol. wt. 169.1 M.f. C3H8NO5P Form Colourless crystals. M.p. 189.5?.5 °C B.p. Decomp. >200 °C V.p. 1.31 ´ 10-2 mPa (25 °C) KOW logP <-3.2 (pH 2-5, 20 °C), (OECD 107; EEC A8) Henry <2.1 ´ 10-7 Pa m3 mol-1 S.g./density 1.705 (20 °C) Solubility In water 11.6 g/l (25 ºC). Insoluble in common organic solvents, e.g. acetone, ethanol and xylene. The alkali-metal and amine salts are readily soluble in water. Stability Glyphosate and all its salts are non-volatile, do not photochemically degrade and are stable in air. Glyphosate is stable to hydrolysis at pH 3, 6 and 9 (5-35 °C). pKa 5.77?.03, 2.18?.02 (20? °C), (OECD 112) F.p. Not flammable
APPLICATIONS
Biochemistry Inhibits 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), an enzyme of the aromatic acid biosynthetic pathway. This prevents synthesis of essential aromatic amino acids needed for protein biosynthesis. Mode of action Non-selective systemic herbicide, absorbed by the foliage, with rapid translocation throughout the plant. Inactivated on contact with soil. Uses Control of annual and perennial grasses and broad-leaved weeds, pre-harvest, post-planting/pre-emergence and in stubble, in cereals, peas, beans, oilseed rape, flax and mustard, at c. 1.5-2 kg/ha; as a directed spray in vines and olives, at c. 4.3 kg/ha; in orchards, pasture, forestry and industrial weed control, at c. 4.3 kg/ha. As an aquatic herbicide, at c. 2 kg/ha. Formulation types SG; SL. Compatibility Mixing with other herbicides may reduce the activity of glyphosate.
