ALFALFA

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:
