Monsanto

A new study supports earlier findings that Monsanto’s biggest selling weedkiller may actually be harming crop production by increasing the incidence of fungal root disease. This could be why the "RoundUp-ready" corn and soybeans that Monsanto has engineered to be used with the herbicide have failed to deliver promised yields.

Add this to recent stories of RoundUp’s ubiquitous presence, concerns of serious health effects such as birth defects, and the creation of superweeds (as RoundUp resistance spreads from engineered crops to weeds) — you'd think this would be the final nail in RoundUp’s coffin, right? Not quite, but we're keeping the pressure on.

The ecological, economic and agronomic disaster accompanying herbicide-tolerant transgenic crops is by now well known: over 10 million acres of superweeds resistant to Monsanto’s weedkiller, RoundUp; farm machinery breaking on RoundUp-resistant pigweed thick as a baseball bat; Monsanto paying farmers to spray their fields with competitors’ herbicides; a new generation of transgenic crops in the pipeline engineered to withstand older even more dangerous chemicals like 2,4-D.

Last week brought more bad news for Monsanto: the same phenomenon is also occurring in insect pest populations that are developing resistance to transgenic “Bt corn” in the Midwest.

Like many people, I once believed in the safety of RoundUp. Back in the 1980s when I was a young graduate student in ecology, it was the “safe” herbicide of choice for clearing weeds from study plots.

Monsanto would like us to continue to believe their flagship product is safe, but the data are increasingly saying otherwise. The latest? Widespread exposure is a near certainty, since RoundUp — now linked to birth defects — shows up regularly in our water and air.

Monsanto has announced it will start selling a new genetically engineered sweet corn directly to U.S. farmers this fall, the Los Angeles Times reports. In doing so, the biotech heavyweight will be directly challenging Syngenta, which has until now been the sole producer of the genetically engineered (GE) sweet corn sold at your grocery store since the late 1990s.

My kids had a great baseball season playing in Little League this Spring. We've now moved on to other summery things like swim lessons in Berkeley's freezing fog. So I was caught off-guard by last week's surprise collision between my work and home worlds, namely the revelation that USDA has just given Scotts Miracle Gro (the lawn chemical company and much decried sponsor of Major League Baseball), the go-ahead for a new and once again totally unnecessary genetically engineered product: Roundup Ready lawn grass. And they may have pulled off a de facto deregulation of all future GE products in the process.
