Yesterday the EPA issued a cancellation order for Closer (sulfoxaflor). The link below provides more information on that cancellation. The cancellation means that the product can no longer be sold at this time. However, if growers still have this product on hand, they are permitted to apply the product previously purchased according to the label directions on the container. It is unknown at this time when sulfoxaflor may be reregistered.
