DuPont Authentication Velpar L H - 63377 - Manual (Page 7)

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.
VELPAR L is recommended for control of certain weeds
where the following species are grown:
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
Georgia Mississippi Rhode Island
Florida New Hampshire South Carolina
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.

plantation for 1 year or more.
