Jay from Florida writes

Will Diquat Water Weed and Landscape Herbicide kill spike rush?

Will Diquat be effective in killing spike rush that has overtaken lake shore?

Answer:

Diquat is not labeled for Aqua plant or Spike Rush. Sonar RTS is labeled to treat for Spike Rush. This Ready-To-Use liquid formula contains Fluridone which is very effective in controlling unwanted aquatic vegetation including duckweed.
