ASTM International Committee E35 on Pesticides, Antimicrobials and Alternative Control Methods invites all interested parties to join a new task group on biorationals. The task group is under the jurisdiction of Subcommittee E35.22 on Pesticide Formulations and Delivery Systems.

The primary purpose of the task group will be to define pesticide products being marketed as biorationals. In response to ever-increasing demands for production of food and fiber, the growth in nontraditional pest control agents based on biologically derived materials continues to grow as well. Several terms are being proposed for these new materials. Among the terms currently being marketed are “biopesticides,” “biorationals,” “biological control agents” and “biologicals.”

Definitions are needed to eliminate confusing terminology and, in some cases, the overlap of terminology being applied to the same material. The task group will also consider the implications of possible U.S. Environmental Protection Agency regulatory actions for biorationals.

To accomplish its initial goal of developing definitions, the task group has begun work on its first proposed standard, WK32362, Terminology for Biorationals.
