–Applications to soils high in organic matter (greater
than 5%).
• Injury may occur when DuPont™ VELPAR® DF 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).
–Foliage after bud break.
–Gravelly or rocky soils, exposed subsoils, clay knobs,
sand, or sandy soil with 85% or more sand.
VELPAR® DF is recommended for control of certain weeds
in pineapple.
APPLICATION INFORMATION
Mix the proper amount of VELPAR® DF in water. Add a
surfactant at the rate of 0.25% V/V.
Use the lower rates on coarse-textured soils or in areas
where rainfall exceeds 65 inches per year. Use the higher
rates on fine-textured soils or in areas where rainfall is less
than 65 inches per year.
Intercrop period - Apply VELPAR® DF as a broadcast
spray in 100–400 gallons of water per acre at the rate of
1/3 - 2 1/3 pounds per acre. For aerial application, use at
least 10 gal water per acre.
Post mulch, preplant - Apply VELPAR® DF as a
broadcast spray in 100–400 gallons of water per acre at the
rate of 1/3 - 2 1/3 pounds per acre.
Post plant, before planted cuttings start active growth -
Apply VELPAR® DF as a broadcast spray in 100–400
gallons of water per acre at the rate of 1/3 - 2 1/3 pounds per
acre. A post-plant application should be made after planted
cuttings start to grow only when weed growth has escaped
control by other herbicide applications.
Prior to forcing first ratoon - Apply VELPAR® DF as a
broadcast spray in 100–400 gallons of water per acre at the
rate of 1/3 - 2 1/3 pounds per acre.
Directed postemergence (pineapple and weeds) inter-
space application - Apply VELPAR® DF as a directed
spray 3–10 months after planting in 50–200 gallons of water
per acre (broadcast basis) at the rate of 1/3 - 2 1/3 pounds
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 gallons per acre depending on size) with
1 1/3 - 2 1/3 pounds per 100 gallons of water as a spot
treatment.
Treatments to field edges and roadsides - Apply
VELPAR® DF at 2 1/3 - 4 8/10 pounds per acre in 100–400
gallons of water.
WEEDS CONTROLLED
VELPAR® DF is recommended for the control or
suppression of the following species in pineapple crops:
* Suppression – a visible reduction in plant population and/or
plant vigor as compared to an untreated area and generally not
accepted as control.
USE PRECAUTIONS - PINEAPPLE
• Do not exceed 4.8 lb VELPAR® DF per acre per crop.
• Do not apply VELPAR® DF within 181 days of harvest.
VELPAR® DF is recommended for selective weed control
in sugarcane except in the State of Florida.
APPLICATION INFORMATION
Apply a single treatment of VELPAR® DF per year using a
fixed-boom sprayer and a minimum of 25 gallons per acre
unless otherwise directed.

highest recommended rate for the indicated soil texture per crop
(18–24 months).
A surfactant is recommended for all uses.
