Polyethoxylated tallow amine (POEA) is a surfactant added to Roundup and other herbicides as a wetting agent. [17] POEA is not a single surfactant, but a complex mixture. The composition of each POEA surfactant is a proprietary trade secret. Monsanto's RoundUp, for example, contains a proprietary POEA surfactant called MON 0818 at a 15% ...
The percentage of POEA varies. A 1997 US government report said that Roundup is 15% POEA while Roundup Pro is 14.5%. [136] Since POEA is more toxic to fish and amphibians than glyphosate alone, POEA is not allowed in aquatic formulations. [137] [136] [138] As of 2000, at least 58 studies existed on the effects of Roundup on a range of organisms ...

2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.
Formulation terminology follows a 2-letter convention: (e.g. GR: granules) listed by CropLife International (formerly GIFAP then GCPF) in the Catalogue of Pesticide Formulation Types (Monograph 2); see: download page. Some manufacturers do not follow these industry standards, which can cause confusion for users.
Current Roundup Ready crops include soy, corn (maize), canola, [2] sugar beets, [3] cotton, and alfalfa, [4] with wheat [5] still under development. Additional information on Roundup Ready crops is available on the GM Crops List. [6] As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties. [7] [8]
