The term “superweeds” is the most commonly used slang for a weed that has become resistant to one or more herbicide mechanisms of action. In reality, there is no such thing called “super” about herbicide-resistant weeds. To remove this common misconception about superweeds, the Weed Science Society of America (WSSA) in 2014 published a two-page fact sheet. This publication also clarifies the common myth of the development of superweeds because of GMO crops. There is no...

When glyphosate is applied to plants (e.g., crops or weeds) a certain percentage is absorbed and transported throughout the plant. The amount absorbed is variable depending on the application rate and the type of plant. Very little of the absorbed glyphosate is degraded by the plant and cannot be removed. Its persistence in plants is also variable. Federal regulatory agencies have established allowable limits for glyphosate residues in many different crops to protect human and animal health....

While biodiversity is an important issue, the relationship to agriculture and to agricultural crop protection chemicals is a bit complex.  First of all, since its beginnings 10,000 or more years ago, farming has been quite intentionally an effort to make one plant species dominant in any given tended area or field.  From the plant biodiversity side, the struggle has always been with other plant species that are particularly “weedy” which means they are well adapted to...

To expand on the answer to your question, glyphosate is used in the production of wheat in the U.S., however, its use is limited. In the majority of U.S. wheat fields, it isn’t used at all. In fact, for 2016, it was applied to only 33 percent of wheat acres in the U.S., according to an independent consumer research firm, GfK. Of this 33 percent, nearly all of the acres have glyphosate applied when a harvestable wheat crop is not present, either in fallow or no-till cropping systems...
