APPLICATION TIMING

EASTERN US

Apply VELPAR L as a broadcast or banded spray in the spring prior to conifer bud break to lessen conifer injury potential.

WESTERN US

Rainbelt (areas of high spring rainfall): For best results, apply as a broadcast or banded spray in the late winter or spring when weeds are actively growing, but prior to conifer budbreak.. If application is made after conifer 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 as a broadcast or banded spray 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. Weed 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. For band application, use proportionately less. For example, use 1/2 of the broadcast rates when treating a 3-ft band where row spacing is 6 ft.

IMPORTANT PRECAUTIONS - FORESTRY

•Do not use VELPAR L in nurseries, seedbeds, or ornamental plantings.

•On tracts of land where various soil types are present and VELPAR L rate selection is difficult, conifer damage or less- than-expected vegetation suppression may occur due to the different rates required for various soil types.

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

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

–Applications to soils high in organic matter (greater than 5%).

•Following harvest, allow stumps and injured trees sufficient time to adequately resprout before applying VELPAR L.

•Where burning is desired, burn vegetation only after any brush has completely defoliated, at least twice, allowing for sufficient root uptake of VELPAR L

•Do not use VELPAR L on frozen soils; use in spring after snow melt.

•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 L.

•When applying VELPAR L after transplanting, wait until rainfall has settled the soil around the base and root systems of the transplants before making the treatment.

•Crop injury may occur when VELPAR L is used:

–On trees that show poor vigor, insect damage, disease, winter injury, or other stress conditions

–On any soil containing less than 1% organic matter

–On loamy sand or sandy loam with less than 2% organic matter, except Jeffrey pine and Ponderosa pine

–On conifer foliage after conifer bud break.

–On gravelly or rocky soils, exposed subsoils, clay knobs, sand, or sandy soil with 85% or more sand.

–On crop species not listed on this label

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