I purchased this 1-1/3 oz bottle of Monsanto's Manage on Ebay sold as "new" from a seller who said they bought it at a lawn business surplus auction. The bottle was not sealed, which I knew before I bought it. Since the bottle has no seal, I want to be sure this is Manage before I spray it on my St. Augustine. I don't want to take a chance and kill my lawn if the contents are not as advertised. I seached the internet but could not locate any pictures of what Manage looks like so I have attached this image. Is this Monsanto's Manage? Thanks to all who provide feedback.
