The Weed Science Society of America (WSSA) announced the availability of the 10th edition of its popular Herbicide Handbook – a trusted resource used by educators, researchers, growers, extension agents, government officials, students and others interested in weed management.

First published more than three decades ago, the handbook offers comprehensive information on the more than 230 herbicides currently available in the U.S. It includes physical properties, mode of action, environmental fate, solubility, toxicity to humans and wildlife, binding properties and much more.

The new edition has been completely updated and reorganized in an easy-to-navigate alphabetical format. It also includes approximately 20 new herbicide compounds introduced since the last edition was published.

A handy glossary includes definitions of technical terms and acronyms, a conversion table for measurements, lists of adjuvants that improve herbicide performance, and an updated genealogy of agrichemical companies that reflects how the industry has changed through the years.

“Dozens of weed scientists volunteered their time in support of the project,” says Dale Shaner, a past president of WSSA and editor of the new edition. “They’ve helped us bring together a comprehensive body of information that should be useful to anyone who uses or studies herbicides.”
