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 ...
From the late 1970s to 2016, there was a 100-fold increase in the frequency and volume of application of glyphosate-based herbicides (GBHs) worldwide, with further increases expected in the future. Glyphosate is absorbed through foliage, and minimally through roots, and from there translocated to growing points.
Following its 1970 introduction, Monsanto's last commercially relevant United States patent on the herbicide glyphosate (brand name RoundUp) expired in 2000. Glyphosate has since been marketed by many agrochemical companies, in various solution strengths and with various adjuvants, under dozens of tradenames.
Monsanto was a pioneer of optoelectronics in the 1970s. 1970: Legal: The United States Department of Agriculture halts the use of 2,4,5-T (manufactured by Monsanto) on all food crops except rice. 1972: Products: DDT is banned under most circumstances. 1974: Products
Concerns were raised about toxicology tests conducted by Industrial Bio-Test Laboratories in the 1970s [71] and Craven Laboratories was found to have fraudulently analysed samples for residues of glyphosate in 1991. [72] Monsanto has stated that the studies have since been repeated. [73]
Franz and his research team screened possible metabolites and synthesized compounds and eventually discovered glyphosate in 1970. [2] Although all of the patents regarding glyphosate list Franz as the sole inventor and the Monsanto Company as the assignee, Franz acknowledged that the discovery was a group effort.
This is a list of herbicides. These are chemical compounds which have been registered as herbicides . The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [ 1 ]
A 2008–2009 survey of 144 populations of waterhemp in 41 Missouri counties revealed glyphosate resistance in 69%. Weeds from some 500 sites throughout Iowa in 2011 and 2012 revealed glyphosate resistance in approximately 64% of waterhemp samples. As of 2023, 58 weed species have developed glyphosate resistance.
