Optigard Flex does not list (Z)-9-hexadecenal as any of its active ingredients. The inactive ingredients are privy to the manufacturer and not disclosed, so we cannot say whether or not the product contains (Z)-9-hexadecenal. You may wish to contact the manufacturer directly for more information. You can reach Syngenta by calling 800-334-9481. We are not aware of a product that we currently carry that contains this ingredient.
