DuPont Authentication Velpar L H - 63377 - Manual (Page 5)

VELPAR L is recommended for control of certain weeds in
established alfalfa grown for hay, except in the states of North
Dakota and South Dakota. Do not use on alfalfa grown for
seed in any state except California.
APPLICATION TIMING
NONDORMANT AND SEMI-DORMANT VARIETIES
In the following states, make a single application during winter
months when alfalfa plants are in the least active stage of
growth:
Arizona Kansas New Mexico Utah
California Montana Oklahoma Washington
Colorado Nebraska Oregon Wyoming
Idaho Nevada Texas
In the following states, make a single application either in the
spring before new growth exceeds 2" in height or to stubble
after cutting following hay removal and before regrowth
exceeds 2" in height:
Connecticut Maine New Hampshire Vermont
Delaware Maryland New Jersey Virginia
Illinois Massachusetts New York West Virginia
Indiana Michigan Ohio Wisconsin
Iowa Minnesota Pennsylvania
Kentucky Missouri Rhode Island
Severe alfalfa injury may result following application after
cutting if either the regrowth is more than 2" high, significant
stubble is left after alfalfa cutting, or the air temperature is above
90 °F.
DORMANT VARIETIES
Make a single application after alfalfa becomes dormant and
before new growth begins in the spring. Where weeds have
emerged, use a surfactant.
For the states of Montana and Wyoming, refer to supplemental
labeling for use directions and precautions.
USE RATES
Use higher rates on hard-to-control species, fine textured soils,
soils containing greater than 5% organic matter, or under
adverse environmental conditions or when weeds are stressed
due to low rainfall.
Select the appropriate dose for soil texture and organic matter
content as follows:
VELPAR L (Pt/Acre)
Soil Texture Percent Organic Matter in Soil
Description <1% 1–5% >5%
Coarse
Loamy sand, sandy loam 2–3
2–3 4–6
Medium
Loam, silt loam silt, clay
loam,sandy clay loam 2–3 3–6 4–6
Fine
Silty clay loam, sandy
clay, silty clay, clay 3–6 3–6 4–6
Rate restrictions are also noted in Important Precautions and
Seed Alfalfa (California Only).
WEEDS CONTROLLED
VELPAR L, when applied preemergence or early
postemergence at the following rates, will control these
species:
1–2 Pt/Acre
2–4 Pt/Acre
4–6 Pt/Acre
* Partial control
VELPAR L, when applied in late spring or after cutting at
the following rates, will control these species:
2–6 Pt/Acre
SPRAY EQUIPMENT
Apply VELPAR L using a fixed boom power sprayer or
aerial equipment.
MIXING INSTRUCTIONS
Add VELPAR L to a water-filled tank and mix it
thoroughly. Apply it in at least 20 gal of water per acre by
ground or 5 to 10 gal of water per acre by air. Use at least
5 pts of water for every 1 pt of VELPAR L.
