Customer Reviews for Semera SC Herbicide

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.

I purchased the semera sc, to kill the watermeal in my pond. Waited until the wind pushed it all to one end. I mixed 2.5 oz to 30 gallons of water added about a cup of surfactant. Sprayed it thoroughly and also sprayed the entire shore line. In about 10 days 99 percent of the watermeal was gone. The pond was completely covered. I had tried 2 different herbicides prior with no results. 10 days later still looks great. Glad to have my pond back. Thanks Houston

I had watermeal covering my entire pond. I previously tried two other products with no success. I waited until the wind blew it all to one end. I mixed 2.5 oz. to 30 gallons of water. Thoroughly sprayed it, then sprayed the entire shoreline. About 10 days later about 99 percent gone. Still looks great 20 days after. I don't remember if I got the Semera sc from ya'll or not. But am extremely satisfied with the product. Thanks Houston
