Potential for delayed orchardgrass seeding during glyphosate-resistant alfalfa establishment
Few herbicides are labeled for weed control when establishing alfalfa (Medicago sativa L.)-grass mixtures. Varying the planting date of the grass in relation to alfalfa and adjusting herbicide application timing could improve weed control and forage grass safety. The research objective was to evaluate the use of glyphosate [N-(phosphonomethyl) glycine] for weed control in seedling ...

Stacked corn hybrids show inconsistent yield and economic responses in New York
Stacked (two to three transgenic traits) corn (Zea mays L.) hybrids represented 40% of U.S. corn in 2008, despite limited agronomic studies. Field-scale studies were conducted on four farms in New York for 2 yr to evaluate the agronomics and economics of double-stacked {glyphosate resistance and Bt (Bacillus thuringiensis) European corn borer [Ostrinia nubilalis (Hübner)] trait} hybrids when ...

Behavior of atrazine in limited irrigation cropping systems in Colorado: prior use is important
Received for publication October 28, 2008. Glyphosate-resistant (GR) corn may be a major component of new cropping systems to optimize the use of limited irrigation water supply while sustaining production. Because atrazine is an important tool for residual weed control in GR corn, we examined atrazine binding to soil, dissipation, movement, and early season weed control in limited and full ...

Volunteer corn presents new challenges for insect resistance management
Genetically-modified (GM) corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] dominate the North American agricultural landscape and are becoming increasingly important as biofuels. However, as herbicide-tolerance and insecticidal traits are often simultaneously expressed by individual plants, glyphosate [N-(phosphonomethyl) glycine]-resistant (GR) volunteer corn is becoming a widespread ...

Effects of the herbicide dicamba on non‐target plants and pollinator visitation
Nearly 80% of all pesticides applied to row crops are herbicides, and these applications pose potentially significant ecotoxicological risks to non‐target plants and associated pollinators. In response to the widespread occurrence of weed species resistant to glyphosate, biotechnology companies have developed crops resistant to the synthetic‐auxin herbicides dicamba or 2,4‐D, and once ...

Ninth Circuit Denies Requests to Stay Use of Enlist Duo Herbicide During Judicial Review
On August 11, 2015, the U.S. Court of Appeals for the Ninth Circuit denied a motion for a stay pending review filed on December 18, 2014, by the Natural Resources Defense Council (NRDC), as well as a subsequent stay motion filed on February 6, 2015, by the Center for Food Safety and other petitioners (Case Nos. 14-73353 and 14-73359, consolidated). Both motions requested that the court stay an ...

Why are certain herbicides banned?
Herbicides, also known as weedkillers, are chemical substances used to control and kill unwanted plants (weeds), leaving the desired plants unharmed. While these products are very useful for farmers, they are not always safe. In fact, many herbicides that were in common use around the world a few years ago are slowly being banned. In this blog post, we will look at a few herbicides that are used ...

Environmental Groups File Opening Briefs Challenging EPA’s Decision to Register Enlist Duo
On October 23, 2015, in the U.S. Court of Appeals for the Ninth Circuit, the Natural Resources Defense Council (NRDC) and other environmental groups including the Center for Food Safety (CFS, et al.) (together, Petitioners) filed separate opening briefs in Case Nos. 14-73353 and 14-73359 (consolidated) arguing that the U.S. Environmental Protection Agency’s (EPA) decision to register Dow ...

The complex nature of GMOs calls for a new conversation
An honest discussion of genetically modified organisms must move beyond narrow concepts of human health to the wider social and environmental impacts of engineered crops. The GMO debate is one from which I’ve kept a purposeful distance. For one thing, it’s an issue that has already garnered more than its fair share of attention. For another, when you consider that many domesticated ...
