To apply, determine the volume of water to be treated in acre-feet. Dilute according to the label directions (dilution rate varies). Spray uniformly over the water surface with a tank or backpack sprayer. Allow material to rain down in coarse droplets for better surface penetration.

Weedtrine D Aquatic Herbicide

Weedtrine-D with diquat, is a broad spectrum, rapid-acting, contact herbicides. Ideal for use on small bodies of water or small weed patches. Successfully controls a broad range of submersed, floating and emersed weeds in still lakes, ponds, and drainage ditches. Great on land too!


Use around patios, ornamental gardens, and along fence lines.


Rapidly absorbed by foliage.  Begin's to work immediately on contact. Wilting and loss of foliage occur quite rapidly. 


Effective anytime live foliage is accessible. Best results when applied to well developed foliage, but before growth becomes too dense or weeds flower.


Turbid water or mud covered foliage will reduce absorption and effectiveness. For difficult to control weeds, add Cutrine-Plus Liquid to boost effectiveness.  In or out of water, Weedtrine-D Liquid is very strongly bound to foliage and will not rinse off.


One gallon of Weedtrine-D Liquid covers 4,000 sq. ft. of submersed weeds or 8,000 to 10,000 sq ft. of floating, emersed, or terrestrial weeds.


For submersed weeds dilute Weedtrine-D Liquid with 2 to 5 parts of water.  Inject below surface with a tank sprayer or pour in strips 20 to 40 feet apart.


For floating, emersed or terrestrial weeds, use 2.0 to 6.5 oz. of Weedtrine-D Liquid.  Add water to make 1 gallon of spray.  Thoroughly spray exposed foliage.  Thorough contact with foliage is necessary.

Treat heavy infestations in sections of 1/3 to 1/2 of total weed volume to avoid oxygen depletion.  Allow 5 to 7 days before continuing to untreated sections.
