A: First, your question appears to refer to one or more studies that have been retracted from, or never formally published in, a peer-reviewed scientific journal. If you are unfamiliar, retraction is the process by which scientific papers are officially withdrawn from the public record. According to Retraction Guidelines published by the Committee on Publication Ethics: “Journal editors should consider retracting a publication if:they have clear evidence that the findings are unreliable...

A: Thanks for asking about the toxicity of glyphosate versus that of surfactants used with glyphosate. For herbicides like glyphosate to be most effective at controlling unwanted plants, they need to be applied with a surfactant. Surfactants (short for “surface-acting agents”) are soapy substances that help to reduce surface tension of the water so the drop of spray solution can spread over the surface of a leaf and help to penetrate the waxy layer (the cuticle) of the plant. Herbicidal soaps are... Continue Reading

A: Generally speaking, complex traits are more difficult to manipulate than simple traits like herbicide resistance. However, it has been repeatedly shown that by manipulating the expression of regulatory genes or signaling proteins, one can control entire developmental or metabolic pathways that control complex traits. Dr. James is somewhat correct that drought tolerance is more complex than herbicide resistance, but researchers have been successfully engineering plants for drought... Continue Reading

A: Your question could be answered in various ways depending upon how one interprets it.  We use GM seeds for growing both corn and soybeans here on our farm.  The benefits of biotech seeds include the reality that we now are using less pesticides and other chemicals on our crops, as well as the fact that it allows us to use less tillage (break-up) of the soil. This means less land erosion, a very good plus for the environment. In my opinion, the biggest problem with the seeds is... Continue Reading
