Not working on watermeal
By Laurie in minnetonka mn on 07/07/2023
Bought this because they claimed it kills watermeal. Still have it after multiple sprays.
Expert response:
We apologize you did not get the expected results. Here is a bit more information that will help you have a successful application for watermeal. Semera SC is a contact herbicide that quickly degrades in the water column so plants that DO NOT initially come in contact with the herbicide will not be controlled. Coverage is essential for effective watermeal control. All floating weeds need to be exposed to lethal concentrations in all parts of the water body. Any watermeal escapes left in the water column will quickly re-infest the water body. Any untreated escapes or re-introductions of plants that were not treated will reestablish in areas where surface weeds have been previously controlled. Semera SC must be applied across the entire water body surface where the watermeal is present. If not, control will be limited and the watermeal will quickly repopulate the water body. We hope this information is helpful to you. Please let us know if you have any additional questions. We are always happy to help.
