• Prior to forcing first ratoon - Apply DuPont™ VELPAR®
DF as a broadcast spray in 100–400 gal of water per acre
at the rate of 1/3 - 2 1/3 lb 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 gal of water
per acre (broadcast basis) at the rate of 1/3 - 2 1/3 lb 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
1 1/3 - 2 1/3 lb per 100 gal of water as a spot treatment.
• Treatments to field edges and roadsides - Apply
VELPAR® DF at 2 1/3 - 4 8/10 lb per acre in 100–400
gal of water.
WEEDS CONTROLLED
VELPAR® DF is recommended for the control or
suppression of the following species:
* Suppression
USE PRECAUTIONS - PINEAPPLE
• 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.
• 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 TIMING
- USE RATES - MIXING INSTRUCTIONS
Apply a single treatment of VELPAR® DF per year using a
fixed-boom sprayer and a minimum of 25 gal per acre
unless otherwise directed.
HAWAII
Apply VELPAR® DF pre- or postemergence at the
following rates for the indicated soil texture:
VELPAR® DF (Lb/Acre)
(Plus surfactant
Soils
0.25% by volume)
Coarse Texture
Sand, loamy sand, sandy loam
2/3 - 1 2/10
Medium Texture
Loam, silt loam, silty clay loam
2/3 - 2 1/3
Fine Texture
Clay, gray hydromorphic clay
2 1/3 - 4 8/10
Use the higher levels of the recommended dosage ranges on
soils high in organic matter. Do not apply more than twice the
highest recommended rate for the indicated soil texture per crop
(18–24 months).
A surfactant is recommended for all uses.
For preemergence use only, VELPAR® DF may be applied with
aerial equipment using at least 10 gal of spray per acre.
For spot treatments of emerged weeds, VELPAR® DF may be
applied with a knapsack sprayer in concentrations of
0.6 - 4.8 lb per 100 gal of water. Apply a sufficient volume to
thoroughly wet weed foliage, but do not exceed 40 gal of spray
per treated acre. Use the lower concentrations on coarse-textured
soils that are low in organic matter, and use the higher concen-
trations on fine-textured soils that are high in organic matter.
LOUISIANA
Apply 2/3 - 1 2/10 lb of VELPAR® DF per acre broadcast in the
fall before sugarcane emerges or in the spring before active cane
tillering begins. Fall treatments of 2/3 - 1 2/10 lb per acre may
be followed by a spring treatment of 2/3 - 1 2/10 lb per acre. Do
not apply more than 2 lb per year. Use the higher levels of the
recommended dosage range on fine-textured soils.
PUERTO RICO
For preemergence treatments, apply 1/3 - 2/3 lb of VELPAR®
DF per acre.
For postemergence treatments, apply 1/3 - 2/3 lb of VELPAR®
DF per acre to weeds after they have emerged. Use the lower
rates on coarse-textured soils and the higher rates on fine-
textured soils (high in clay or organic matter). Each ratoon may
receive up to 2/3 lb of VELPAR® DF per acre.
For spot treatment of emerged weeds, VELPAR® DF may be
applied with a knapsack sprayer in concentrations of 1/3 - 2/3 lb
per 100 gal of water. Apply a sufficient volume to wet the weed
foliage. Do not exceed 100 gal of spray per treated acre. Use the
lower concentration on coarse-textured soils and the higher
concentration on fine-textured soils.
Note: Since it is difficult to calibrate “spot” knapsack
applications, extra care must be taken not to exceed the rate
equivalent of the maximum of 2/3 lb VELPAR® DF per acre.
Do not apply more than 1 1/3 lb of VELPAR® DF per acre per
crop season.
TEXAS
Apply 2/3 - 2 1/3 lb of VELPAR® DF per acre. On plant cane,
apply the herbicide before the cane emerges or as a directed
layby treatment. On stubble cane, apply VELPAR® DF
preemergence (up to the 3-leaf stage) or as a directed layby
treatment. A pre- or early postemergence treatment may be
