Weedtrine D Aquatic Herbicide, Applied Biochemists

Weedtrine D Aquatic Herbicide is a broad-spectrum liquid aquatic herbicide for use in and around still lakes, ponds, lagoons, ditches, non-crop, or non-planted areas controlling a broad range of filamentous algae and submerged and floating aquatic weeds.

Weedtrine D Aquatic Herbicide controls submersed, floating and emergent weeds including duckweed.  A surfactant is necessary when using this product with any weed on or above the water surface.  Water use is restricted for irrigation, drinking (animal or human) and swimming, see label for details.  Active ingredient is 8.53% diquat dibromide.  Application rate for submersed weeds is 5 - 10 gallons per surface acre of vegetation.

Weedtrine D Aquatic Herbicide is a non-volatile herbicide for use in controlling submersed, floating aquatic and marginal weeds. This product works by being absorbed by the weed. Herbicidal effects are visible within a few days. Optimum results are seen if the weeds are young and actively growing. Treatment of dense weed areas may result in oxygen loss from decomposition of dead weeds.
