Glyphosate

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.
