When applying Diquat Herbicide always mix with an approved surfactant (such as Alligare 90) per the label instructions. Add the rest of the water to the sprayer and mix well. Step 3: On a fan spray nozzle setting, apply the Diquat to the target areas until they are completely wet but making sure not to spray to the point of runoff.

If using a hand sprayer, for example, 2 gallon sprayer, put 1 gallon of water and 1 gallon of Diquat into the sprayer and spray the contents over an acre of the area. Per the product label, it should be applied in the spring or early summer when the weeds are actively growing and when water temperatures have reached or exceeded 50 degrees.
