I’ve held a variety of roles in Monsanto’s regulatory group since joining the company in 1991. Regardless of my role, whether it was in our Stewardship Group or as a Toxicologist in our Product Safety Center, my focus is on the safe use of our products.

As a mom, I am concerned about the safety of products as well. As a toxicologist who focuses on pesticide safety, I can tell you that glyphosate herbicides are backed by one of the most extensive worldwide human health, safety and environmental databases ever compiled for a pesticide product. In fact, evaluations spanning four decades, the overwhelming conclusion of regulatory agencies and independent experts worldwide has been that glyphosate, the active ingredient in Roundup® branded...

That is a great question, and I wish I could give you a short answer, but a lot of work and scientific evaluation have gone into understanding what happens to glyphosate after it is applied to Roundup Ready crops like corn and to ensuring your family and mine have safe food to eat.   Most glyphosate applications in Roundup Ready corn occur before the corn kernels start to develop; therefore, very little glyphosate is present in the kernels, so residues in the kernels are low. Typical... Read More

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... Read More

Glyphosate, the active ingredient in Roundup branded herbicides, is not banned in any country and is registered in more than 100 countries around the world. Regulatory agencies such as the U.S. Environmental Protection Agency (EPA) and scientific bodies such as the World Health Organization have reviewed numerous studies conducted according to international guidelines and good laboratory practices and concluded that glyphosate does not cause cancer or birth defects.  There have...
