View Rule

In March 2021, EPA issued a proposal to codify product performance data requirements to support registration of products claiming efficacy against three categories of invertebrate pests: those identified to be of significant public health importance (e.g., ticks, mosquitoes, cockroaches, etc.), wood-destroying insects (e.g., termites), and certain invasive invertebrate species (e.g., Asian long-horned beetle). The latter two categories are considered to be of significant economic or ecological importance. Product performance data (efficacy studies) document how well the pesticide performs the intended function (such as killing or repelling) against an invertebrate pest. The Pesticide Registration Improvement Extension Act of 2018 (PRIA 4) requires EPA to publish the final product performance data requirements no later than September 30, 2021.
