General Information


HURDLE 3.8 ACS herbicide is recommended for preemergence control of grasses and certain broadleaf weed species as they germinate.

HURDLE 3.8 ACS can be used in and around field, liner, and container grown ornamental nurseries.

HURDLE 3.8 ACS will not control established weeds. Therefore, areas to be treated should be free of established weeds at the time of treatment, or HURDLE 3.8 ACS may be used in conjunction with herbicides registered for postemergence use in noncropland areas and ornamental sites. Consult the labels of those herbicides for suggested treatments, rates to be used and precautions or restrictions for use in these areas.

The efficacy of HURDLE 3.8 ACS will improve if the application is followed by one-half inch of rainfall or its equivalent in sprinkler irrigation. If HURDLE 3.8 ACS is not activated by rainfall or irrigation within 30 days, erratic weed control may result.

Applied according to label directions and under normal growing conditions, HURDLE 3.8 ACS herbicide or HURDLE 3.8 ACS herbicide tank-mix combinations will not cause crop injury. Overapplication can result in crop stand loss, crop injury, or soil residues. Uneven application can decrease weed control or cause crop injury.

Seedling diseases, cold weather, excessive moisture, high soil pH, high soil salt concentration, or drought can weaken seedlings and plants, and increase the possibility of plant damage from HURDLE 3.8 ACS.


Uniformly apply with properly calibrated ground equipment in sufficient water per acre to uniformly treat the area with a spray pressure of 25 to 50 psi. Maintain continuous agitation during spraying with good mechanical or bypass agitation. Avoid overlaps that will increase rates above those recommended. Avoid application when winds may cause drift.

Avoid unintentional contact of spray solution with driveways, stone, wood, or other porous surfaces. Rinse immediately with water to avoid staining. Avoid mechanically scrubbing until surface area is thoroughly rinsed.

Limitations, Restrictions, and Exceptions


HURDLE 3.8 ACS herbicide is recommended for preemergence control of most annual grasses and certain broadleaf weeds as they germinate on noncropland areas such as sign posts; pumping installations; fence rows; storage areas; windbreaks and shelterbelts; and other similar areas. HURDLE 3.8 ACS herbicide may be tank mixed with Roundup Pro, Karmex, Finale, diuron, glyphosate or other products to provide bare ground; or, total vegetation control; or, can be used to provide greater plant selectivity in areas where such action may be desired. Such sites might have roots of landscape vegetation, ornamentals, or desirable trees encroaching into the treated zone. Refer to tank mix partner labels regarding effects on desirable plants. Applications may be made to existing weeds controlled by the partner herbicide. Recommended rates should be determined from the product labels prior to use. Follow the most restrictive label instructions.
