resistant crops - Click here |
* Glyphosate resistance has spread to kochia weed populations in Kansas
with GM driven glyphosate resistance in general estimated to be affecting nearly 11
million acres in the US (Reuters, 26
February 2010)
* Scientists have voiced support for research which shows rising levels of pesticide
applications on GM crops in the United States (Nature
Biotechnology, February 2010)
* A study published in the Proceedings of the National Academy of Sciences has found that
the occurrence of glyphosate resistant weeds in America could threaten the sustainable use
of GM crop glyphosate herbicide-resistant technology (ABC, Australia, 12
January 2010)
* Glyphosate herbicide resistance in weeds continues to spread in the United States and is
now occurring in Iowa (Kansas
Farmer, 18 December 2009)
* Herbicide resistant GM crops in the
United States are continuing to result in increased usage of herbicide compared to non-GM
systems (Reuters,
17 November 2009)
* In some GM crops glyphosate resistance has become so severe that
farmers are having to resort to manual weeding (ABC
News, 6 October 2009)
* The stacking of GM traits is leading to complications in the control of volunteer plants
and increasing risks of insect resistance (AgProfessional, September
2009)
* Gylphosate resistant weeds have become such a problem in genetically
engineered crops that some farmers in the US are turning back to using residual herbicides
and even hoes, according Ford L. Baldwin of Practical Weed Consultants, LLC (Delta Farm Press, 20
August 2009)
* One of the reasons for the rapid uptake of GM crops is the lack of independent science
to give farmers impartial information on their actual performance, and some people are
finally beginning to notice (Financial
Times, Blog, 11 August 2009)
* Glyphosate resistant pigweed has been confirmed in 21 counties in Arkansas since first
confirmed in Mississippi County since 2005 (University of Arkansas, 10 August 2009)
* Resistance to glyphosate has become so prevalent in some parts of the United States
because of the introduction of genetically modified crops that some farmers are now
resorting to hand weeding and Monsanto are paying farmers to switch to other herbicides (Memphis
Commercial Appeal, 9 August 2009)
* In Tennessee and Arkansas glyphosate can no longer be considered a
pigweed herbicide due to resistance problems (Delta Farm
Press, 4 August 2009)

fallen as the economic reasons for growing them weaken (The
Organic & Non-GMO Report July/August 2009)
* Glyphosate resistant weeds are spreading in Argentina with the growing of Roundup Ready
soya (Geoforum,
Vol. 40, No. 4. (July 2009), pp. 623-633)
* The use of glyphosate in 'Roundup Ready' crops has lead to 15 species of weed being
resistant to the herbicide with the problem especially acute in the US (Agweek
8 June 2009)
* Glyphosate-resistant weeds now cover nearly 38 million acres in the
United States (Delta
Farm Press, 15 May 2009)
* Glyphosate resistant weeds are starting to emerge in Argentina following the
introduction of Roundup Ready GM technology (ScienceDirect,
28 April 2009)
The
explosion in weeds resistant to the glyphosate herbicide is continuing to spread across
millions of acres in the United States causing some farmers to consider moving back to
non-GM crops (France 24, 19 April 2009)
The development
of glyphosate resistant weeds on US farms is encouraging the search for alterative to
Roundup Ready technology. Bayer's Liberty Link soybeans will require multiple applications
and/or use with other herbicides (Delta Farm Press, 13 February 2009)
Glyphosate
resistance continues to be a problem for American cotton growers to the point where they
are having to consider other weed management programmes that do not rely on Roundup Ready
GM technology, including use of other herbicides and soil tillage (Delta Farm Press, 6
Feburary 2009)
As
glyphosate resistance increases in Roundup Ready soy bean crops more farmers are
considering returning to conventional beans and using residual herbicides as an
alternative to glyphosate (Delta Farm Press, 5 February 2009)

Insecticidal crops:
* Pesticide applications on Bt
Cotton in India are rising as new pests attack GM varieties (Telegraph
(Calcutta) 16 February 2010)
* Although Bt crops in America helped reduce the use of insecticides in
cotton crops initially, in Mississippi spraying has begun rising again resulting in total
costs to farmers which are increasingly uneconomic (Delta Farm Press, 15
January 2010)
* Data shows Bt resistance is genetically modified corn and cotton crops is more
commonplace than many researchers are prepared to acknowledge (Arizona
Daily Star, 22 December 2009)
* The stacking of GM traits is leading to complications in the control of volunteer plants
and increasing risks of insect resistance (AgProfessional, September
2009)
