Application Rate
Low and flexible
» 12-20 fl oz per acre
» Common use rate is 16 fl oz per acre
-
Application Timing
Treat when weeds are actively growing and not stressed by drought or other condition. Increase herbicide rate within the labeled rate range as the season progresses and plants become more mature. Higher rates will produce an increase in residual.
-
Application Method
Ground Broadcast Application: Spray volumes greater than 10 gallons per acre generally provide better coverage and better control.
Aerial Broadcast Application: Use 2 gallons or more per acre total spray volume. 5 gallons per acre or greater will generally provide better coverage and better control, particularly in dense and/or tall foliage.
High-Volume Foliar Application: High volume foliar treatments may be applied at rates equivalent to a maximum of 20fl oz per acre per annual growing season.
Spot Application: Spot treatments may be applied at 40 fl ozs of DuraCor® per acre, if an application is not made to more than 50% of the treatable acre. Spray volume should be sufficient to thoroughly and uniformly wet weed foliage, but not to the point of runoff.
