We would recommend waiting at least 14 days to use any other products in your pond after applying Reward Landscape and Aquatic Herbicide.
Reward Landscape and Aquatic Herbicide is not labeled to control American Lotus, but we do carry Rodeo that is labeled for American lotus and several other aquatic weeds. Reward is the only herbicide we currently carry that is labeled to control coontail. Please keep in mind that this weed can be very difficult to control, and a combination of both chemical control and physical removal will yield the best results.
