South Dakota received a section 18 use for Amitraz strips. Eight other states, including Florida are piggy-backing on the approval. Amitraz had a section 3 use many years ago, but the manufacturer pulled it when a batch of old material was sickening bees. The plasticizer had broken down turning dark and oily and toxic to bees. Several less than honest beekeepers used it after the notice was posted looking for easy money. White and powdery are good, brown and oily is bad. Amitraz has continued in use in less litiguous nations. Amitraz is or has goon through recent trails to get a new section 3. It is still quite effective.
