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 is recommended for use in and around established tree plantations (including Christmas Trees); pulpwood and fiber farms; in and around established ornamentals planted in non cropland areas. HURDLE 3.8 ACS may be applied at planting or to established trees. When making an application at planting, it is important that slit closure be achieved to prevent HURDLE 3.8 ACS from directly contacting the tree roots or being washed into the root zone via the open slit or root stunting may occur. For post emergence control of weeds, tank-mix combinations of HURDLE 3.8 ACS plus Roundup, Finale, or other labeled herbicides are recommended. Refer to approved labeling for species recommendations. Recommended rates for the tank-mix compounds should be determined from the product labels of both the HURDLE 3.8 ACS and partner herbicide prior to use. Precaution must be exercised to prevent combination sprays from direct contact with desirable foliage or injury may result. HURDLE 3.8 ACS plus diuron or simazine combinations will broaden weed control spectrum, however, use of combinations may restrict HURDLE 3.8 ACS usage in sensitive areas. Refer to manufacturers' labels for specific use directions, precautions, and limitations before use and follow those that are most restrictive.
