Attack of the Monsanto Superinsects Tue Aug. 30, 2011 3:04 AM PDT But now the pitches are wearing thin. Dumping a single herbicide onto millions of acres of farmland has, predictably enough, given rise to weeds resistant to that herbicide. Such "superweeds" are now galloping through cotton and corn country, forcing farmers to resort to highly toxic herbicide cocktails and even hand-weeding. More than 11 million acres are infested with Roundup-resistant weeds, up from 2.4 million acres in 2007, reckons Penn State University weed expert David Mortensen. And now insects are developing resistance to Monsanto's insecticide-infused crops, reports the Wall Street Journal. Fields planted in Monsanto's Bt corn in some areas of the Midwest are showing damage from the corn rootworm—the very species targeted by Monsanto's engineered trait. An Iowa State University scientist has conclusively identified Bt-resistant root worms in four Iowa fields, the Journal reports. motherjones.com/tom-philpott/2011/08/monsanto-gm-super-insects

January 25, 2013 Glyphosate Resistant Weeds – Intensifying Not only are glyphosate resistant weeds spreading geographically, the problem is also intensifying with multiple species now resistant on an increasing number of farms. US farmers told us that 61.2 million acres of cropland are infested with glyphosate resistant weeds, almost doubling since 2010. www.stratusresearch.com/blog07.htm

The first confirmed case of glyphosate-resistant horseweed (marestail) bolted out of the gate in Delaware in 2000. U.S. farmers have been struggling to get it under control since, said Bill Curran, Pennsylvania State University weed scientist. Glyphosate-resistant horseweed was subsequently found in Maryland and New Jersey in 2002, and Pennsylvania in 2003. There are now 21 states with confirmed populations of herbicide-resistant horseweed.

Monsanto Inches Closer To Biggest Biotech Launch In Company’s History February 05, 2015 Similar to bacteria that have adapted to frequently used antibiotics over time, super weeds have gained immunity to herbicides. Weed scientists estimate there are more than 400 different herbicide-resistant weeds around the world. Resistant weeds hurt crops by competing for sunlight and nutrients. St. Louis-based Monsanto’s biotechnology team has been working for nearly a decade on two new soybean and cotton varieties designed to withstand dicamba – an infrequently used herbicide that weeds have not caught up with yet. will.illinois.edu/news/story/monsanto-inches-closer-to-biggest-biotech-launch-in-companys-historyCotton Dicamba, glufosinate-tolerant Approved January 20, 2015 www.nature.com/nbt/journal/v33/n4/fig_tab/nbt0415-328_T1.htmlHerbicide's brand names include Banvel, Diablo, Oracle and Vanquish.
