WASHINGTON, Sept. 19, 2022 — Farmers used to worry about weeds. Then, herbicides solved that problem. At least for a while. In 1997, there were 432 new patents for herbicides; by 2009, there were only 65. Developing broad-spectrum glyphosate and “Roundup Ready” crops worked so well that people basically stopped looking for new herbicides. But then the weeds started fighting back. https://youtu.be/vsbYyUfLwh8

The American Chemical Society (ACS) is a nonprofit organization chartered by the U.S. Congress. ACS’ mission is to advance the broader chemistry enterprise and its practitioners for the benefit of Earth and all its people. The Society is a global leader in promoting excellence in science education and providing access to chemistry-related information and research through its multiple research solutions, peer-reviewed journals, scientific conferences, eBooks and weekly news periodical Chemical & Engineering News. ACS journals are among the most cited, most trusted and most read within the scientific literature; however, ACS itself does not conduct chemical research. As a leader in scientific information solutions, its CAS division partners with global innovators to accelerate breakthroughs by curating, connecting and analyzing the world’s scientific knowledge. ACS’ main offices are in Washington, D.C., and Columbus, Ohio.
