SOYBEANS - OVER 4% ORGANIC MATTER - FINE SOIL
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.
GENERAL PRECAUTIONS AND RESTRICTIONS
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.
APPLICATION OF TRICOR DF WITH HERBICIDE SPRAY EQUIPMENT
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.
TriCor DF herbicide tank-mix combinations may be used for preplant incorporated applications, pre-emergence surface applications, Split-Shot application and Extended Split-Shot application. TriCor DF may also be used as an overlay application following a preplant incorporated application of a recommended grass herbicide and alone as a preemergence surface application. All these applications can be applied with ground equipment, and some can be applied with aerial spray equipment. In addition, TriCor DF can be applied as a postemergence directed spray to soybeans in certain states.
SPECIAL PRECAUTIONS (Soybeans): Injury to soybeans may occur when TriCor DF is used under the following conditions:
1. When soils have a calcareous surface area or a pH of 7.5 or higher.
2. Due to the sensitivity of certain soybean varieties, TriCor DF should not be used on Altona, AP 55, AP 71, Asgrow 6520, Burlison, Coker 102, Coker 156, Dassel, GL 3202, Govan, Maple Amber, NB 3665, NKS 1884, Paloma 350, Portage, Regal, Semmes, Terra-Vig 505, Terra-Vig 606, Tracy, Vansoy, and Vinton 81. Consult your United Phosphorus, Inc. Representative or your seed supplied for information on the tolerance to TriCor DF of newly released soybean varieties, prior to use of TriCor DF.
3. When applied in conjunction with soil-applied organic phosphate pesticides.
4. Over application or boom overlapping may result in stand loss and soil residues.
5. Uneven application or improper incorporation can decrease the level of weed control and/or increase the level of injury.
6. When applied to any soil with less than 1/2% organic matter.
7. Soil incorporation deeper than specified.
8. When sprayers are not calibrated accurately.
9. When heavy rains occur soon after application, especially in poorly drained areas where water may stand for several days.
10. When soybeans are planted less than 1-1/2 inches deep, particularly in pre-emergence application.
Activation: A minimum amount of soil moisture is required to activate TriCor DF. In areas of low rainfall, pre-emergence applications to dry soil should be followed with light irrigation of 1/4 acre inch of water. Do not apply heavy irrigation immediately after application. As with many surface-applied herbicides, weed control and crop tolerance may vary with rainfall and/or soil texture.
Grazing and Feeding Treated Vines: Treated vines may be grazed or fed to livestock 40 days after application when TriCor DF is applied alone or with Treflan, Metolachlor, S-Metolachlor, Prowl, or Lasso.
Do not use treated vines for feed or forage when TriCor DF is applied with Sonalan, linuron plus Lasso, or linuron plus Metolachlor or S-Metolachlor.
Rate Ranges: Where a rate range is shown, use a lower rate on soils that are coarse-textured or low in organic matter.
Use a higher rate on soils that are relatively fine-textured or high in organic matter.
Replanting: If replanting is necessary in fields treated with TriCor DF as directed on the label, the field may be replanted to soybeans. When replanting, use a minimum of tillage is recommended. Do not apply a second treatment as injury to soybeans may occur.
TRICOR DF ALONE
TriCor DF (Alone) Pre-emergence Application: The following rates of TriCor DF may be applied pre-emergence to soybeans through center pivot or lateral move sprinkler irrigation systems that apply water in a uniform manner. Refer to “Chemigation” section of the label for directions.
TriCor DF can be applied broadcast or banded. This application may be made during planting or as a separate operation after planting but before crop emergence. See the “GENERAL INFORMATION” section in the front of the label.
Do not apply to sand soils, or to sandy loam or loamy sand soils containing less than 2% organic matter. Do not incorporate into soil or apply more than once per season.
1 For control of lambsquarters, redroot pigweed and wild mustard, and for suppression of green, yellow and giant foxtails on alkaline (calcareous) soils in Nebraska, Minnesota, South Dakota and North Dakota only, apply TriCor DF at rates of 1/3 lb/acre on medium soils and 1/3 to 1/2 lb/acre on fine soils regardless of soil organic matter percentage (use 1/2 lb only where soil pH is less than 7.5 and weed pressure is heavy). The 1/3 lb/acre rate of TriCor DF alone can be applied regardless of soil pH. For control of other weeds listed on the label use TriCor DF at full rates specified in the table above, but note that crop injury may occur on soils having a calcareous surface area or a pH of 7.5 or higher.
2 Silty clay loam soils are transitional soils and may be classified as medium textured soils in some regions of the U.S.
3 Refer to the appropriate section of the label for use of TriCor DF on soybeans in coarse soils with 0.5% or more organic matter in certain states.
