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


(Hawaii Only)

TriCor DF, a selective herbicide, is effective as a pre-emergence and an early postemergence broadcast application for control of certain grass and broadleaf weeds. When applied as a spot treatment, it also provides excellent control of perennial grasses and broadleaves.

Ground Application: TriCor DF should be mixed by filling the spray tank half full of clean water. Then add the specified amount of TriCor DF to suit the total tank capacity and the rate of application per acre (preferably 25 to 35 gallons per acre). Complete filling the tank and maintain sufficient agitation during mixing and spraying to ensure a uniform spray mixture.

Aerial Application: TriCor DF may be used for use in aerial spray equipment as a pre-emergence or postemergence application to irrigated sugarcane. Aerial spray equipment should be calibrated to apply the proper amount of TriCor DF in 5 to 10 gallons of spray mixture per acre.

For aerial and chemigation application methods on sugarcane the maximum application rate is 2-2/3 lb TriCor DF/acre.

To assure that spray will not adversely affect adjacent sensitive nontarget plants, apply this product by aircraft at a minimum upwind distance of 400 ft from sensitive plants.

TriCor DF applied pre-emergence or postemergence to the sugarcane as a broadcast spray or spot treatment will effectively control the following when weeds are less than 3 inches in height.


POSTEMERGENCE: Apply specified dosage per acre as a broadcast spray to control weeds prior to “close in” time when cane shades out the weed growth.

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.
