Use a minimum of 250 lb dry bulk fertilizer per acre and up to a maximum of 450 lb per acre. To impregnate or coat the dry bulk fertilizer with VELPAR L, direct the nozzles to deliver a fine spray towards the fertilizer for thorough coverage while avoiding spray contact with mixing equipment. Uniform impregnation of VELPAR L to dry bulk fertilizer will vary, and if the absorptivity is not adequate, the use of an absorptive powder may be required to produce a dry, free- flowing mixture. Microcel E (Johns Manville Product Corporation) is the recommended absorbent powder. When another herbicide is used with VELPAR L, mix and impregnate the fertilizer immediately.

Apply impregnated fertilizer immediately unless experience has shown that it can be stored without becoming lumpy and difficult to spread.

Select the rate of VELPAR L to apply per acre from the appropriate section of this label. Then refer to the rate chart below to determine the amount of VELPAR L that should be impregnated on a ton of dry bulk fertilizer, based on the amount of fertilizer to be distributed in one acre.

APPLICATION

Uniform application of VELPAR L-impregnated dry fertilizer is essential for satisfactory weed control. Accurate calibration of the application equipment is essential for uniform distribution to the surface. The recommended method of application is to apply 1/2 the recommended rate and overlap 50%. This results in the best distribution pattern.

CHRISTMAS TREES

VELPAR L is recommended for control of certain weeds where the following species are grown:

Austrian pine

Noble fir

Douglas fir

Ponderosa pine

(western US only)

Scotch pine

Grand fir

Sitka spruce

Loblolly pine

 

Do not use VELPAR L on Christmas trees in the following states:

Alabama

Louisiana

New Jersey

Texas

Arkansas

Maine

New York

Vermont

Connecticut

Maryland

North Carolina

Virginia

Delaware

Massachusetts

Pennsylvania

West Virginia

APPLICATION TIMING

EASTERN US

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

WESTERN US

Areas of greater than 20" annual rainfall - Apply VELPAR L 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 conifer foliage.

Areas of less than 20" annual rainfall - Apply VELPAR L 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-ft band where row spacing is 6 ft.

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

First year plantings - Transplant stock that is 2 years old or more (1 year old for loblolly pine). Apply VELPAR L only if rainfall has settled the soil around the base and root systems of the transplants.

Established trees - Trees that have been planted in the plantation for 1 year or more.
