APPLICATION INFORMATION
EASTERN US
Apply DuPont™ VELPAR® L from early spring to early summer after hardwoods have broken bud and before full leaf expansion.
Applications made over the top of pines may result in excessive pine injury under conditions of high humidity and temperature (80 degrees F).
WESTERN US
Rainbelt (areas of high spring rainfall): For best results, apply in late winter or spring when brush is actively growing, but prior to conifer budbreak. If application is made after bud break, use directional spray equipment to prevent contact with conifer foliage, as injury may result.
Snowbelt (areas of low spring rainfall): For best results, apply in the fall before soil freezes and after the final resting bud has hardened on the conifers. Or, spring applications may be made after snow cover melts in anticipation of rainfall prior to conifer budbreak. Brush control results from spring treatments will be dependent on sufficient rainfall following application to activate VELPAR® L.
USE RATES
The rates listed below are for broadcast application. Use the higher rate range for the harder to control (*suppression) species in the PLANTS CONTROLLED listings of the Site Prep and Release sections. Do not use more than one application of VELPAR® L per year.
