Tsunami DQ Aquatic Herbicide - 1 Qt.

Sanco Industries

Tsunami DQ Landscape and Aquatic Herbicide

Tsunami DQ herbicide is used to control weeds in the following sites:

  • aquatic areas
  • commercial greenhouses and nurseries
  • dormant established turfgrass (bermudagrass, zoysiagrass – nonfood or feed crop)
  • landscape, industrial, recreational, commercial, residential, and public areas
  • ornamental seed crops (flowers, bulbs, etc. – excluding the state of California)
  • turf renovation (all turf areas except commercial sod farms) 

Tsunami DQ is effective in controlling duckweed, water hyacinth, pondweed, slender leaf pond weed, coontail and other aquatic weeds, as well as some emerged annual broadleaf and grass weeds in established dormant bermudagrass lawns. It works by being absorbed by the weed, and, within a few days, the weed shows signs of dying. Optimum results are seen if the weeds are young, actively growing, and free from stress. Avoid spray drift to crops, ornamentals, and other desirable plants during application, as injury may result. Clean all spray equipment with water after use. Avoid application to muddy water or disturbing the water during application that may reduce weed control. To avoid reduced herbicidal activity, do not use dirty or muddy water in preparing spray solutions of Tsunami DQ. Avoid application under conditions of high wind, water flow, or wave action.
