PHYSICAL CHEMISTRY
glyphosate
Mol. wt. 169.1
M.f.:C3H8NO5P
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)
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).
APPLICATIONS
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.
Selected tradenames: 'Rodeo' (isopropylammonium salt) (Monsanto); 'Roundup' (isopropylammonium salt) (Monsanto); 'Sting' (isopropylammonium salt) (Monsanto) etc
