The main active ingredient of Roundup is the isopropylamine salt of glyphosate. Another ingredient of Roundup is the surfactant POEA (polyethoxylated tallow amine). Monsanto also produced seeds which grow into plants genetically engineered to be tolerant to glyphosate, which are known as Roundup Ready crops. The genes contained in these seeds ...
The glyphosate-based herbicide RoundUp (styled: Roundup) was developed in the 1970s by Monsanto. Glyphosate was first registered for use in the U.S. in 1974. [4] Glyphosate-based herbicides were initially used in a similar way to paraquat and diquat, as non-selective herbicides. Attempts were made to apply them to row crops, but problems with ...
Convolvulus arvensis, or field bindweed, is a species of bindweed in the Convolvulaceae [1] native to Europe and Asia. It is a rhizomatous and climbing or creeping herbaceous perennial plant with stems growing to 0.5–2 metres (1.6–6.6 ft) in length.
It was marketed as Roundup in 1971. [17] The development of glyphosate-resistant crop plants, it is now used very extensively for selective weed control in growing crops. The pairing of the herbicide with the resistant seed contributed to the consolidation of the seed and chemistry industry in the late 1990s.
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 ...
Monsanto was one of four groups to introduce genes into plants in 1983, [3] and was among the first to conduct field trials of genetically modified crops in 1987. It was one of the top-ten U.S. chemical companies until it divested most of its chemical businesses between 1997 and 2002, through a process of mergers and spin-offs that focused the ...
