APPLICATION INFORMATION

EASTERN US

Apply VELPAR® DF as a broadcast spray in the spring prior to bud break. If application is made after bud break, use directional spray equipment to prevent contact with foliage.

WESTERN US

Areas of greater than 20 inches annual rainfall - VELPAR® DF may be applied as a broadcast spray in the spring prior to conifer bud break. If application is made after bud break, use directional spray equipment to prevent contact with foliage.

Areas of less than 20 inches annual rainfall - VELPAR® DF may be applied in the fall before the soil freezes or in the spring after snow cover melts, but before conifer bud break occurs.

USE RATES

The rates listed below are for broadcast application. For band application, use proportionately less; for example, use 1/2 of the broadcast rates when treating a 3-foot band where row spacing is 6 feet. Use the higher end of the rate range on the heavier soil type.

Do not use more than one application of VELPAR® DF per year.

USE PRECAUTIONS

CHRISTMAS TREES

•Do not use VELPAR® DF in nurseries, seed beds, or ornamental plantings.

•Do not add a surfactant in applications over the top of conifers.

•Weed control results from spring applications depend on sufficient moisture to activate VELPAR® DF.

•Do not cut treated vegetation for forage or hay nor graze domestic animals on treated areas for 60 days following application.

•Poor weed and brush control may result from the following: –Heavy duff or slash present at the time of application. –Use on poorly drained sites.

–Applications made when soil is saturated with water and rain is imminent within 24 hours.
