General Information


Use Precautions

Apply this product only as specified on the label. Do not apply by aerial application.

This product is formulated as an emulsifiable concentrate containing 7.0 pounds of active EPTC per gallon.

This product is a selective soil applied herbicide for preemergence control of many annual and perennial grasses, broadleaf weeds and sedges as they germinate, but it will not control established weeds. Established weeds should be controlled before applying this product or by use of an appropriate postemergence herbicide in a tank mix combination treatment with this product.

When applied as a spray to the soil surface this product must be incorporated immediately after application. Ideally, application and incorporation should be done simultaneously. Incorporation prevents loss of the herbicide to evaporation. This product may be tank mixed with any product having the same crop use and restrictions allowing co-application. This product treatments may be followed by any registered herbicide for additional weed control.

Follow this product label directions carefully. Over application can result in crop stand loss, crop injury, or excessive soil residues. Uneven application, improper soil incorporation, or soil incorporation deeper than recommended can decrease weed control and/or cause crop injury.

Seedling diseases, cold weather, excessive moisture, shallow or deep planting, low or high soil pH, high soil salt concentration, or drought can weaken seedlings and plants and increase the possibility of crop damage and/or reduced crop yields from use of this product.

To assure uniform application, mix the prescribed amount of this product with a sufficient volume of water to provide thorough coverage of target area. Follow the recommendations given in the “APPLICATION” section of the label.

See label for mixing instructions.


Apply this product in 10 to 50 gallons of water (20 or more gallons of liquid fertilizer) per acre with conventional spray equipment. Increase spray volumes when treating dense weed foliage or fields containing excessive crop residues to increase penetration and coverage.

Band applications should be equivalent to the broadcast rate and application volume per acre.

DO NOT apply this product if wind velocity is high enough to cause drift of the application spray off the target site or irregular spray patterns.

Choose spray nozzles capable of producing spray droplets able to maintain good foliage coverage and weed control. Avoid using nozzles and excessive spray boom pressure that may increase the formation of fine droplets most likely to drift.


Apply this product in 10 or more gallons of water per acre.

SPECIAL EQUIPMENT DESIGNED FOR SUBSURFACE APPLICATION MUST BE USED. Injector and sweep units must be rigidly mounted on the planter or cultivation unit. When using sweeps at planting they must be mounted ahead of the planters.

SOIL INJECTION: Injector shanks must be spaced 2.5 to 3 inches apart and mounted in staggered positions to avoid trash buildup. Set shanks to inject this product 2 to 3 inches below the soil surface. The width of the band in which weed control is desired will determine the number and spacing of injector shanks required per row. (Example: Four injector shanks spaced 3 inches apart give a 12-inch band.) A broadcast application can be made by increasing the number of shanks. The two shanks adjacent to the drill row must be 1.25 to 1.5 inches on either side of it, EXCEPT IN COTTON WHERE THE DISTANCE MUST BE 4 INCHES ON EITHER SIDE OF THE DRILL ROW, AND SUGAR BEETS WHERE THE DISTANCE MUST BE 2.75 INCHES ON EITHER SIDE OF THE DRILL ROW.

COVERED SWEEPS: Set the sweeps to run below the soil surface deep enough to cover this product with 2 to 3 inches of soil. Calibrate by measuring the spray band width at the back of the sweep, not sweep width. For broadcast applications, stagger sweeps on double tool bar so they overlap sufficiently to allow spray bands to meet. NOTE: When applying with either injectors or sweeps, this product must be applied deep enough to allow 2 to 3 inches of soil to remain over the treatment after planting operations.


This product may be applied via dry fertilizers impregnated with this product and incorporated in the soil before planting for the control of grass and broadleaf weeds. See Tables on the label for examples of approved dry fertilizers and rates of application.

See label for chemigation information application instructions.


Follow the recommended rates as directed in the specific crop sections of the label. Use higher label rates when heavy weed populations are anticipated or excessive crop litter remains in the field prior to seedbed preparation or application.

Some rates are dependant upon the different growing conditions found in the United States. Use rates for some crops may vary between regions, check specific crop sections of the label for rate in geographic area treatment is to be made.

Limitations, Restrictions, and Exceptions



This product may be used for weed control in Irish Potatoes. This product will not control established weeds. Prior to application, it is recommended that weeds be removed via cultivation or other methods.

The Superior is sensitive to this product and some early season stunting or injury may occur under less than optimum conditions for germination and growth.

When applying tank mixtures or sequential applications with this product, always read the companion product label(s) to determine application timing, specific use rate, and weed species controlled. In addition, follow all precautions and restrictions that apply to each product used. Always follow the most restrictive label.


Preplant Incorporated: Apply and incorporate the required rate of this product just before planting. Apply as a band treatment for incorporated application to Potato beds. A Fall application can be made to fields located in Minnesota and North Dakota to be planted in Irish Potatoes the following spring. Fall applications should be made before the ground freezes.

USE REGION: Pacific Northwest Region (see map on the label).


- Purple nutsedge and Yellow nutsedge: May not be controlled at less than 3.5 pints of this product per acre.

- Perennial weeds must be turned under and chopped up thoroughly prior to treatment. The underground rhizomes of quackgrass and the rhizomes and stolons of bermudagrass must be cut up so that only four or less nodes remain on a strand. For the suppression or control of quackgrass and bermudagrass, the disc must be set to cut 6 inches deep. Use 4.5 to 7 pints of this product for quackgrass and 3.5 to 7 pints for bermudagrass. Incorporate this product by discing or apply in the irrigation water after the rhizomes and stolons have been cut up. Consult recommendations for crops on which these higher rates may be used. Nutsedge may not be controlled by water-run applications in heavier soils.

Restrictions for Use on Potatoes:

DO NOT exceed the maximum labeled rate of this product in any region.

DO NOT apply to Potatoes within 45 days of harvest (within 30 days of harvest for Potatoes treated via irrigation in the Western region).

Pre-Harvest Interval

45 days
