General Information


SOIL TEXTURE: As used on the label, “Coarse soils” are loamy sand or sandy loam soils. “Medium soils” are loam, silt loam, silt, sandy clay, or sandy clay loam. “Fine soils” are silty clay, silty clay loam, clay, or clay loam. Silty clay loam soils are transitional soils and may be classified as medium textured soils in some regions of the U.S.


Do not allow sprays to drift on to adjacent desirable plants.

Apply this product only as specified on the label.

Do not use on other crops grown for food or forage. Observe all cautions and limitations on labeling of all products used in mixtures.

Do not rotate any crop not listed on the label for 18 months following application of TriCor DF.

For all uses: Low-pressure and high-volume hand-wand equipment is prohibited.


Use a standard low pressure (20 to 40 psi.) herbicide boom sprayer equipped with suitable nozzles and screens no finer than 50-mesh in nozzle and in-line strainers. Agitate thoroughly before and during application with bypass agitation.

GROUND APPLICATION: Apply the proper rate of TriCor DF in a minimum of 10 to 40 gallons of spray mixture per acre broadcast.

Banded Application: Use proportionally less TriCor DF per acre in a band versus a broadcast application. For band application use 1/4 to 1 gallon of spray mix per inch of band width regardless of row spacing.

EXAMPLES: (1) To treat a 15-inch band on rows 30 inches apart, use one-half of the broadcast rate of TriCor DF. (2) To treat a 14-inch band on rows 42 inches apart, use one-third of the broadcast rate of TriCor DF.

AERIAL APPLICATION: Where permitted, apply specified rate in a minimum of 2 to 10 gallons of spray mixture per acre.

Do not apply aerially when wind speed is greater than 10 mph.

NOTE: Do not apply aerially when TriCor DF is tank-mixed with Lasso.

For All Applications of TriCor DF: Sprayer must be accurately calibrated before applying TriCor DF. Check sprayer during application to be sure it is working properly and delivering a uniform spray pattern. As the volume of spray mixture decreases per acre, the importance of accurate calibration and uniform application increases. Avoid other application, misapplication, and boom and spray swath overlapping that will increase spray dosage. (Crop injury may occur as a result). Avoid spray skips and gaps which allow weeds to grow in untreated soil. Do not apply when weather conditions favor spray drift and/or when sensitive or cool season crops, such as cole crops, onions, peas, or strawberries are present in adjacent fields or in areas where wheat is growing in coarse textured soils.

Refer in the label for tank mix information.

Limitations, Restrictions, and Exceptions



Follow all applicable precautions and restrictions on other portions of the label and on the full federal label. For application ONLY by commercial applicators and only on established bermudagrass turf (such as parks, athletic fields, golf course fairways and cemeteries) which has a mowing height of one-half inch or greater.

Not for use in commercial greenhouses, nurseries, on sod farms, or on grass grown for seed. For use on plants intended for aesthetic purposes or climatic modification and being grown on golf courses or lawns and grounds.

Do not enter or allow others to enter treated area until sprays have dried. Do not apply to dormant turf in the transitional bermudagrass growing zones which are or can be expected to be adversely affected by cold weather stress.

Do not apply using low-pressure and high-volume hand-wand.

Do not apply more than 2 lbs TriCor DF (1.5 lbs ai) per acre in a single growing season. Do not apply more than once to dormant turf and twice to actively growing turf in a single growing season.

Avoid spray overlaps that will increase dosages above those specified.

Do not apply by air to turf.

Only apply to established bermudagrass turf with a mowing height of one-half inch or more. Do not apply to greens, tees, aprons, or other turf which is closely mowed.

Phytotoxicity may occur if applied within the root zone area of ornamentals, shrubs, or trees. Avoid application to these areas.

Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application.

For best weed control, do not mow treated areas for at least 3 days after treatment. For best results, delay mowing until after rainfall or irrigation is received.

Do not use grass clippings for animal feed.

When applying TriCor DF to turf which is actively growing, use the lower rate in areas where soil pH is greater than 7.5.

Do not allow sprays to drift onto adjacent desirable plants.

Observe all cautions and limitations on labeling of all products used in mixtures.


Having a mowing height of one-half inch or more.


Apply 1/3 to 2/3 lb TriCor DF in 40 gallons of water/A as a uniform broadcast spray. Apply only when turf is vigorously growing and not stressed. Repeat if necessary, but do not apply more often than every 7 days. Do not apply more than twice per season to actively growing. Applications may result in temporary discoloration, which turf soon outgrows.

Observe the “General Precautions and Restrictions” when using this product.

Refer in the label for other weeds controlled when tank mix with MSMA.

Restricted Entry Interval

12 hours

Exception: If the product is soil-injected or soil-incorporated, the Worker Protection Standard, under certain circumstances, allows workers to enter the treated area if there will be no contact with anything that has been treated.
