Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Coppers - Sulfate and Chelated together

Have used reward a number of times and with CU on a couple of situations. Have not used Aquathol + reward. The aquathol works best for us sprayed on with surfactant and water. It rids the pondweed for half to 2/3 of the summer period (about 2 1/2 mths). About twice as long as reward and or CU.
