DuPont Authentication H - 64953 User Manual

NOTE: Severe alfalfa injury may result following
application after cutting if either the regrowth is more than 2
inches high, significant stubble is left after alfalfa cutting, or
the air temperature is above 90 °F.

Make a single application after alfalfa becomes dormant and
before new growth begins in the spring. Where weeds have
emerged, use a surfactant.

Use higher rates on hard-to-control species, (see Weeds
Controlled section below) fine textured soils, soils
containing greater than 5% organic matter, or under adverse
environmental conditions such as temperature extremes or
when weeds are stressed due to low rainfall.

For dormant alfalfa, use a surfactant approved for crops at
the rate of 0.25% v/v (1 quart per 100 gallons of spray
solution).

Select the appropriate rate for soil texture and organic
matter content as follows:

Coarse Texture
Loamy sand,

sandy loam

2/3 - 1

2/3 - 1

1 1/3 -2

Medium Texture
Loam, silt loam

silt, clay loam,
sandy clay loam

2/3 - 1

1 - 2

1 1/3 - 2

1 1/3 - 2

NOTE:
- In the states of MT, ND, SD, and WY, do not exceed a use rate of 

1 1/3 pounds per acre on medium and fine textured soils. 

- In the state of Montana (MT), do not apply to soils with less than 

1.5% organic matter. 

- In the state of Wyoming (WY): 

Do not apply to soils with less than 0.5% organic matter.
Apply to irrigated alfalfa only.

VELPAR® DF, when applied preemergence or early
postemergence at the following rates, is recommended for
the control or suppression of the following species in alfalfa
crops:

* Suppression - a visible reduction in plant population and/or
plant vigor as compared to an untreated area and generally not
accepted as control.

VELPAR® DF, when applied in late spring or after cutting
at the following rates, will control these species listed
below:

Apply VELPAR® DF using a fixed boom power sprayer or
aerial equipment. 

For ground applications apply in a minimum of 20 gallons
of spray solution per acre and by air in a minimum of 5
gallons.
