Emmette from Summit, Mississippi writes
Per the product label Diquat Water Weed and Landscape Herbicide can be used at a rate of .5-2.0 gallons per surface acre in a sufficient carrier along with 16-32 oz per acre of a surfactant for pennywort. Retreat as necessary for densely populated weed areas. If you are using it as a spot treatment, you would use approximately .75 oz per gallon of water plus a surfactant. Spray to completely wet target weeds but not to the point of runoff. Densely packed weeds or mats may require additional applications due to incomplete spray coverage. Repeat as needed. For best results, re-treat weed scapes within 2 weeks of the initial treatment.
