DuPont Authentication H - 65396 manual Use Rates, Spray Equipment, Weeds Controlled

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

DORMANT VARIETIES

Make a single application of DuPont™ VELPAR® L after alfalfa becomes dormant and before new growth exceeds 2 inches in height in the spring. Where weeds have emerged, use a surfactant.

USE RATES

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:

	VELPAR® L (Pints/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

NOTE:

-In the states of MT, ND, SD, and WY, do not exceed a use rate of 4 pints 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.
