Product Q&A

Answer:

We do not recommend applying Roundup Pro Concentrate  to a pond for cattail eradication. Diquat Water Weed and Landscape Herbicide is one of our top products for control of Cattails as well as a multitude of other aquatic weeds. It is not harmful to any aquatic life and will control the weeds in the water as well as along the bank. For Cattails, Diquat Water Weed and Landscape Herbicide may be applied by backpack, airboat, spray handgun, helicopter, airplane, or similar application equipment that results in thorough spray coverage.Spot Treatment:Apply Diquat Water Weed and Landscape Herbicide at 2 quarts per 100 gallons spray carrier (0.5% solution) with an approved aquatic wetting agent at 0.25-1.0% v/v (1 quart to 1 gallon per 100 gallons water). For cattail control, Diquat Water Weed and Landscape Herbicide should be applied prior to flowering at the maximum application rate (8 quarts of Diquat Water Weed and Landscape Herbicide/100 gallons spray carrier) plus the wetting agent. Repeat treatments may be necessary for complete control. Spray to completely wet target weeds but not to runoff. Densely packed weeds or mats may require additional applications due to incomplete spray coverage. Re-treat as needed. For best results, re-treat weed escapes within 2 weeks of the initial treatment. Broadcast Treatment:Apply Diquat Water Weed and Landscape Herbicide at the rate of 0.5-2.0 gallons persurface acre in sufficient carrier along with 16-32 oz./A of an approved wetting agent. Retreat as necessary for densely populated weed areas. Good coverage is necessary for control of the target weeds.
