APPLICATION DIRECTIONS:

Subsurface Applications: For submersed weeds, especially Hydrilla, that have reached the water’s surface, apply Tsunami DQ in a water carrier or an invert emulsion through boom trailing hoses carrying nozzle tips that direct the dilute spray below the water surface to ensure adequate weed coverage.

Bottom Placement: For submersed weeds (ex. Hydrilla, Bladderwort, or Coontail) that have reached the water surface and/or where the water is slowly moving through the weed growth, apply Tsunami DQ in an invert emulsion carrier with weighted hoses that inject the diluted spray solution near the bottom. Adding a copper-based algaecide may improve control. Alternatively, a pretreatment application with a copper based algaecide may improve overall control if algae are present along with submersed weeds.

Surface Application for Submersed Aquatic Weeds: For submerged weeds, apply Tsunami DQ as a spray insufficient carrier to fully cover the target area and to ensure complete coverage of the weed areas. The higher rate is recommended for mixed weed populations. Surface spray applications are not recommended for densely-packed submersed weeds or if water is over 2 feet deep (use subsurface applications of Tsunami DQ in these situations). 

TARGET PESTS: 

Weeds Controlled in Established Dormant Turfgrass: Little Barley, Annual Bluegrass, and Bromes including Rescuegrass, Sixweeks fescue, Henbit, Buttercup, and Carolina Geranium. 

Submersed Weeds Controlled or Suppressed: Bladderwort, Hydrilla, Watermilfoils (including Eurasian), Pondweeds, Coontail, Elodea, Brazilian Elodea, Naiad, and Algae.

Floating and Marginal Weeds: Water lettuce, Water hyacinth, Duckweed, Salvinia spp., Pennywort, Frog’s Bit, and Cattails.
