Just as viruses have evolved to our medicines to over come them,our weeds have developed into what is known as “superweeds”. By definition a superweed is a hybrid plant that contains genes for herbicide resistance;produced by accidental crossing of genetically engineered crop plants with wild plants.These superweeds have developed as a result of GM(genetic modified) farming.It is estimated that 60 million A. have been affected.The plants have developed as an unintended result of growing crops that have been genetically modified to withstand the spraying of weedkillers like Monsanto’s Roundup Ready-also known as glyphosate(a broad spectrum herbicide used to kill weeds).As mentioned the weeds have become immune to the chemicals and then take over the field due to the overuse of Roundup.It is estimated that there are 24 species of such weeds.some examples of “superweeds’ are: pigweed-palmer amaranth,horseweed-conyza canadesis,and ragweed-ambrosia trifida.As result these superweeds take water and nutrients from the intended crops.One crop we/me may not think about in my neck of the woods -Midwest-is cotton.It is affected as well. As our farmers work to feed the world-within the whole industry-more research is needed not only in sensible chemical use but practices that can be applies in large scales.In conclusion it has been expressed that it is a “viscious cycle”-more chemicals-25% more each year-are needed for farmers that use GM crops and to “control” weeds.
