Last week, Corveta announced two new tools, Sequoia® CA and Transform® CA, both with IsoclastTM active, have been approved by the California Department of Pesticide Regulation and will be available in California for the 2026 season. These tools will help farmers fight sap-feeding insects on cotton, alfalfa, leafy vegetables, grapes, and tree crops, including citrus as well as other key crops.
Isoclast active is now available in nearly every state in the U.S. and in 100 countries around the world following California’s approval. Transform® CA and Sequoia® CA with Isoclast™ active represent a new class of insecticides – the sulfoximines – and both products have a favorable environmental profile compared to alternatives on the market.
Transform® CA and Sequoia® CA are designed to control a range of economically destructive and difficult-to-control sap-feeding pests, including most species of aphids, lygus, leafhoppers, mealybugs and whiteflies. Not only do these insects damage crop quality and reduce yield, but they can also serve as vectors for the further spread of plant diseases.
We are pleased to see this registration move forward and will share updates on product availability and purchasing as more information becomes available.
