On March 29, 2017, the U.S. Environmental Protection Agency (EPA) denied a petition that sought to ban chlorpyrifos, a pesticide crucial to U.S. agriculture. Instead, EPA will focus its attention on updating and revising its human health assessment for chlorpyrifos under the standard procedures of the ongoing registration review process. The assessment is scheduled for completion on October 1, 2022, in order to support future decision-making.

On Friday March 24, 2017, the California Department of Pesticide Regulation (DPR) registered the use of Sequoia™ insecticide as a Section 24(c) Special Local Need to control foxglove and lettuce aphids in leafy vegetables and Brassica vegetables. 

Sequoia is a member of a new class of chemistry, the sulfoximines, with excellent efficacy on sucking insects such as aphids, lygus, and certain scale insects. Additionally, there is no cross resistance to other chemistries such as organophosphates, pyrethroids, or neonicotinoids.
