Iron present as ferrous sulfate monohydrate or ferrous sulfate heptahydrate (hereafter referred to as ferrous sulfate) is an herbicide used to control the growth of moss in turf and lawns.
This document presents the final regulatory decision for the re-evaluation of ferrous sulfate. To comply with this decision, the required label amendments must be implemented on all product labels sold by registrants no later than 24 months after the publication date of this document. Registrants of products containing ferrous sulfate will be informed of the specific requirements affecting their product registration(s) and of the regulatory options available to them.
