The ASTM E35.22 Standard for Terminology Related to Biorationals Task Group (Biorationals Task Group) was formed in 2010 as a result of changes in consumer preference about how food is produced and the related increased development and marketing of nontraditional pest control and nutritional products. The goal of the task group is to develop standard definitions to minimize the use of confusing and inconsistent terminology for these types of products. The standard came to life in 2013 with the definition of “biorational,” which is an umbrella term for these pest control and nutritional products. The first biorational term approved was the U.S. Environmental Protection Agency's definition of “biopesticide,” which was published in 2015. Subsequently, several other terms relating to biorationals (e.g., “biopesticides” and specific biopesticides such as “biochemical,” “microbial,” and “plant-incorporated protectant” biopesticides) have been approved.
