95% Purity CAS 1071-83-6 C3H8NO5P Glyphosate Herbicide
Description
In the 1990s, no glyphosate-resistant weeds were known to exist.By 2014, glyphosate-resistant weeds dominated herbicide-resistance research. At that time, 23 glyphosate-resistant species were found in 18 countries. "Resistance evolves after a weed population has been subjected to intense selection pressure in the form of repeated use of a single herbicide."
According to Ian Heap, a weed specialist, who completed his PhD on resistance to multiple herbicides in annual ryegrass (Lolium rigidum) in 1988 – the first case of an herbicide-resistant weed in Australia – by 2014 Lolium rigidum was the "world’s worst herbicide-resistant weed" with instances in "12 countries, 11 sites of action, 9 cropping regimens" and affecting "over 2 million hectares." Annual ryegrass has been known to be resistant to herbicides since 1982. The first documented case of glyphosate-resistant L. rigidum was reported in Australia in 1996 near Orange, New South Wales. In 2006, farmers associations were reporting 107 biotypes of weeds within 63 weed species with herbicide resistance. In 2009, Canada identified its first resistant weed, giant ragweed, and at that time 15 weed species had been confirmed as resistant to glyphosate. As of 2010, in the United States 7 to 10 million acres (2.8 to 4.0 million hectares) of soil were afflicted by herbicide-resistant weeds, or about 5% of the 170 million acres planted with corn, soybeans, and cotton, the crops most affected, in 22 states.In 2012, Charles Benbrook reported that the Weed Science Society of America listed 22 herbicide-resistant species in the U.S., with over 5.7×106 ha (14×106 acres) infested by GR weeds and that Dow AgroSciences had carried out a survey and reported a figure of around 40×106 ha (100×106 acres).[192] The International Survey of Herbicide Resistant Weeds database lists species that are resistant to glyphosate.
In response to resistant weeds, farmers are hand-weeding, using tractors to turn over soil between crops, and using other herbicides in addition to glyphosate.
Monsanto scientists have found that some resistant weeds have as many as 160 extra copies of a gene called EPSPS, the enzyme glyphosate disrupts.
