* Partial control
SPRAY EQUIPMENT
VELPAR L may be applied by ground equipment or by air
(helicopter only).

VELPAR L.
IMPORTANT PRECAUTIONS
- CHRISTMAS TREES
• Do not use VELPAR L 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 L.
• 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.
–Applications to soils high in organic matter (greater
than 5%).
• Crop injury may occur when VELPAR L is used on the
following:
–Trees that show poor vigor, insect damage, disease, winter
injury, or other stress conditions.
–Any soil containing less than 1% organic matter.
–Loamy sand or sandy loam with less than 2% organic matter
(except Jeffrey Pine and Ponderosa Pine).
–Crop species not listed in this label.
–Conifer foliage after conifer bud break.
–Gravelly or rocky soils, exposed subsoils, clay knobs, sand,
or sandy soil with 85% or more sand.
VELPAR L is recommended for control of certain weeds in
pineapple.
APPLICATION TIMING
- USE RATES - MIXING INSTRUCTIONS
Use a sprayer properly calibrated to a constant speed and
rate of delivery.
Mix the proper amount of VELPAR L in water. Add a
surfactant at 0.25% by volume of water.
• Intercrop period - Apply VELPAR L as a broadcast spray
in 100–400 gal of water per acre at the rate of 0.9–7 pt per
acre. For aerial application, use at least 10 gal water per
acre.
• Post mulch, preplant - Apply VELPAR L as a broadcast
spray in 100–400 gal of water per acre at the rate of 0.9–7
pt per acre.
• Post plant, before planting material starts active growth -
Apply VELPAR L as a broadcast spray in 100–400 gal of
water per acre at the rate of 0.9–7 pt per acre.
A post-plant application should be made after planting
material starts to grow only when weed growth has
escaped control by other herbicide applications.
• Post-plant crop harvest, prior to forcing first ratoon -
Apply VELPAR L as a broadcast spray in 100–400 gal of
water per acre at the rate of 0.9–7 pt per acre.
• Directed postemergence (pineapple and weeds) inter-
space application - Apply VELPAR L as a directed spray
3–10 months after planting in 50–200 gal of water per
acre (broadcast basis) at the rate of 0.9–7 pt per acre
(broadcast basis) using a stroller boom or knapsack.
• Directed spot treatments for perennial grasses before
floral induction - Spray perennial grasses postemergence
to wet (50–200 gals per acre depending on size) with
3.5–7 pt per 100 gal of water as a spot treatment.
• Treatments to field edges and roadsides - Apply VELPAR L
at 7–14.5 pt per acre in 100–400 gal of water.
