Glyphosate (N-(phosphonomethyl) glycine) is a non-selective systemic
herbicide, absorbed through the leaves, injected into the bole, or applied to
the stump of a tree, used to kill weeds, especially perennials and broadcast or
used in the cut-stump treatment as a forestry herbicide. Some crops have been genetically
engineered to be resistant to it. Glyphosate was first sold by Monsanto under
the tradename Roundup, but is no longer under patent. It is now also available
in other formulations, e.g. Resolva 24H, which contains glyphosate and diquat.
Glyphosate is effective in killing a wide
variety of plants, including grasses, broadleaf, and woody plants. It has a
relatively small effect on some clover species. By volume, it is one of the
most widely used herbicides. It is commonly used for agriculture, horticulture,
and silviculture purposes, as well as garden maintenance (including home use).
Glyphosate is supplied in several formulations
for different uses:
- Ammonium
salt.
- Isopropyl
amine salt.
- Glyphosate
acid - standalone, as ammonium salt or as isopropyl salt.
- potassium
Salt.
Products are supplied most commonly in formulations
of 120, 240, 360, 480 and 680g
active ingredient per litre. The most common formulation in agriculture is 360g, either alone or with added cationic
surfactants.
For 360g
formulations, European regulations allow applications of up to 12 litres per
hectare for control of perennial weeds such as couch grass. More commonly,
rates of 3 litres per hectare are practiced for control of annual weeds between
crops.
