Glyphosate ²Ý¸Êì¢

Introduction: Glyphosate is a non-selective common and effective herbicide. It is highly soluble in water, non-volatile and does not normally leach to groundwater. It is not persistent in soils but may be in aquatic systems under certain conditions. It is moderately toxic to humans and a skin and eye irritant. It is moderately toxic to birds, most aquatic organisms, earthworms and honeybees.

Product analysis by hplc with u.v. detection (AOAC Methods, 17th Ed., 983.10; CIPAC Handbook, 1985, 1C, 2132; ibid., 1998, H, 182) or by ion-exchange lc with u.v. detection (AOAC Methods, 17th Ed., 996.12). Residues determined by glc (Pestic. Anal. Man., 1979, II ), by gc with MSD ( also applicable to aminomethylphosphonic acid, AOAC Methods, 17th Ed., 2000.05) or by hplc with o-phthalaldehyde post-column reaction specific for primary amines (J. Agric. Food Chem., 34(6), 955-960 (1986)). In environmental water, by hplc determination by o-phthalaldehyde post-column reaction system (AOAC Methods, 17th Ed., 991.08, 10.6.18).

EHC 159 (WHO, 1994). Animals In mammals, following oral administration, glyphosate is very rapidly excreted unchanged and does not bioaccumulate. Plants Slowly metabolised to aminomethylphosphonic acid ([1066-51-9]), which is the major plant metabolite. Soil/Environment In soil (field), DT50 1-130 d, depending on edaphic and climatic conditions. In water, DT50 varies from a few to 91 d. Photodegradation in water occurs under natural conditions, DT50 33-77 d; no substantial photodegradation in soil was recorded over 31 d. In a lab. whole system with water and sediment, DT50 27-146 d (aerobic), 14-22 d (anaerobic). The major metabolite in soil and water is aminomethylphosphonic acid.


Usage: Translocated herbicide that may be applied preplant or preemergence to over 150 crops for control of annual and perennial weeds, woody brush, and trees. Use postdirected in tree and plantation crops, postemergence over Roundup* Ready soybeans, and postharvest in fallow periods and noncropland. For annual and perennial grasses and broadleaf weeds in plantation and other crops, and general weed control in noncropland and as no-tillage in farmland.


Application: 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, in cereals, peas, beans, oilseed rape, flax and mustard, at c. 1.5-2 kg/ha; control of annual and perennial grasses and broad-leaved weeds in stubble and post-planting/pre-emergence of many crops; as a directed spray in vines and olives, at up to 4.3 kg/ha; in orchards, pasture, forestry and industrial weed control, at up to 4.3 kg/ha. As an aquatic herbicide, at c. 2 kg/ha.
