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. Containing 8.53% active diquat dibromide, Weedtrine® D acts as a potent contact killer in plants by disrupting cellular membranes allowing Weedtrine® D to enter plants "short circuit" the plants ability to convert light into energy known as "Photosynthesis."
Weedtrine® D is recommended for small ponds less than 1/2 acre with submerged weed and duckweed problems. Weedtrine® D Aquatic Herbicide is quickly absorbed by plants.
One gallon of Weedtrine® D Liquid covers 4,000 sq. ft. of submersed weeds or 8,000 to 10,000 sq ft. of floating, immersed, or terrestrial weeds. We recommend using Weedtrine® D with the surfactant Cygnet Plus to maximize its effectiveness when applied above water to emergent species. Cygnet Plus reduces the surface tension, allowing the Weedtrine® D to wet the entire leaf instead of rolling off. Absorption and herbicidal action are usually quite rapid, with visible effects in a few days.
