Supplies of Surflan are limited. I cannot independently confirm the following but this is what I was told by a distributor. “The manufacturing facility was damaged and the active ingredient (oryzalin) is in very short supply. It is unclear if oryzalin will or will not be discontinued.”

If you have supplies (or can purchase supplies) the labels are still valid and you can continue to use the Surflan you have. As I get additional information I will update this post.

Information about Surflan herbicide is available in this fact sheet:
