Anticipated Use Sites


Permanent grass pastures, including grasses grown for hay

Conservation Reserve Program (CRP)

Non crop land areas

Timing and Application Methods

Ground Broadcast Application

Spray volumes greater than 10 gallons per acre generally provide better coverage and better control.

Aerial Broadcast Application

Use 3 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 20 fl oz per acre per annual growing season.

Spot Application

Spot treatments may be applied at 20 fl oz of DuraCor™ per acre per annual growing season. Spray volume should be sufficient to thoroughly and uniformly wet weed foliage, but not to the point of runoff.

Anticipated 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. 

Weed and Feed

Possibility to apply through treated dry fertilizer or mixing into liquid fertilizer.

Anticipated Controlled Weeds

Anticipated to control over 140 broadleaf weeds and woody plants.
