Diquat dibromide 37.3%
Diquat, which is sold under the trade name of Reward, is used at 1 gallon per surface acre. It is diluted in 50 to 150 gallons of water per acre and sprayed directly on the floating plants. A nonionic surfactant, which can be purchased at most places that sell Reward, must be added to the Reward/water solution as directed on the Reward label. Reward is a contact herbicide.
That means it immediately causes the plant tissue it comes into contact with to turn brown. Because duckweed and watermeal plants are so small, a single Reward treatment will seldom make contact with and kill all the plants. In addition, Reward does not persist in the water; it is typically gone from the water column by 7 to 10 days after treatment. Therefore, any plants that survive the initial treatment will start to regrow in a few days. A typical scenario after treatment with Reward is that many of the plants will turn brown and sink but the survivors will regrow and again cover the pond. Several treatments of Reward usually have to be made in a single season to keep a pond relatively free of duckweed or watermeal.
Treatments should begin as soon as the plants start to grow in the spring or early summer in order to keep ahead of the growth. It is helpful to treat when the wind has pushed the plants to one end of the pond; the spray should be concentrated on the plants in that area. However, do not forget to spray small patches that may still be floating on other parts of the pond or washed up along the banks. Multiple treatments of Reward can successfully control duckweed; unfortunately, they seldom give effective control of watermeal.
