I heard that story on NPR too. I expect Roundup resistant horseweed to be making an appearance in my neck of the woods, Cumberland County Il., soon as the topography of rolling hills dictates the use of no-till methods that use roundup. As Ean Malcom in Jurassic Park stated, “nature will find a way”. A half century of use of chemicals and antibiotics is already stimulating the adaptation by organisms to our meddling.

eric,

The annual Roundup bath is creating superweeds just as predicted. In the Red River Valley of the North, farmers often rotate Roundup Ready soybeans with wheat, this spring which was wet, a lot of wheat did not come up on last year's RR soybean fields, these fields had to be replanted. In my opinion, in certain growing conditions, Roundup is also carrying over to the next growing season killing any crops without genetic engineered resistance to Roundup.
