DRY BULB ONIONS ETC. - COARSE SOIL - 3% OR MORE ORGANIC MATTER
Mode of Action
Sortie is a root-and-shoot growth inhibitor that controls susceptible germinating seedlings before or soon after they emerge from the soil. Dimethenamid-P is a chloroacetamide herbicide belonging to the herbicide mode-of-action Group 15 (WSSA)/Group K3 (HRAC).
Sortie will provide most effective weed control when applied by ground or aerial equipment and subsequently incorporated into soil by rainfall, sprinkler irrigation, or mechanical tillage prior to weed seedling emergence from soil. Sortie can also be applied through chemigation.
Sortie may be applied as a preplant incorporated, preplant surface, preemergence, early postemergence, or layby (corn) treatment. Sortie may be applied using either water or sprayable fluid fertilizer as the spray carrier. Additionally, Sortie may be impregnated on and applied with dry bulk fertilizer. Sprayable fluid fertilizer as a carrier is not recommended for use after crop emergence. Refer to Additives for more information.
Use rates for Sortie when applied alone, in tank mix, or in sequential applications are given in Table 2 in the label. Refer to Crop-specific Information for additional rate information.
Use rates of this product may vary by soil texture and organic matter. Soil texture groups used in this label are coarse (sand, loamy sand, sandy loam), medium (silt, silt loam, loam, sandy clay loam), and fine (sandy clay, silty clay, silty clay loam, clay loam, and clay).
DO NOT apply to sand-textured soil with less than 3% organic matter (as determined by soil tests, if not known) where depth to groundwater is 30 feet or less. When use rates are expressed in ranges, use the lower rate for more coarsely-textured soils lower in organic matter; use the higher rate for more finely-textured soils high in organic matter.
Preplant Incorporated Application
Apply Sortie and incorporate into the upper (1 to 2 inches) soil surface up to 2 weeks before planting. Use a harrow, rolling cultivator, finishing disk, or other implement capable of giving uniform shallow incorporation. Avoid deeper incorporation or reduced weed control or crop injury may result.
Preplant Surface Application
For use in minimum tillage or no-till production systems, apply Sortie alone or in tank mixes up to 45 days before planting. When making early preplant application (15 to 45 days prior to planting), use the highest rate specified for the specific soil type. Early preplant applications are not for use on coarse-textured soils or in areas where average annual rainfall (or rainfall + irrigation) typically exceeds 40 inches. Early preplant applications may be applied as part of a split application program where the second application is made after planting (use 2/3 of Sortie rate early followed by 1/3 of rate after planting). A split application is recommended when the initial application is made more than 30 days prior to planting. Tank mixes with postemergence herbicides registered for use on the specific crop such as glyphosate, Touchdown herbicide (glyphosate), or Gramoxone Inteon herbicide (paraquat) must be used when weeds are present at the time of application.
Preemergence Surface Application
Broadcast treatment uniformly to the soil surface after planting and before crop emergence. Rainfall, sprinkler irrigation, or shallow mechanical incorporation after application is required to move this product into the upper soil surface where weed seeds germinate. If adequate rainfall or irrigation does not occur and weed seedling emergence begins, a shallow cultivation or rotary hoeing will improve performance.
Early Postemergence Application
Sortie must be applied prior to weed seedling emergence or in a tank mix with products registered for use on the specific crop on this label that control the emerged weeds. Refer to Crop-specific Information for specific postemergence applications by crop.
Use Sortie in field corn, seed corn and popcorn. See Crop-specific Information – Corn for more details on layby application.
Sortie may be used in split application programs where applications are made as part of the methods described above. If applications are less than 2 weeks apart, the total Sortie rate used must not exceed the maximum rate given for each specific soil type. If applications are 2 weeks or more apart, a total Sortie use rate of up to 21 fl. ozs./A per year may be used on any soil type.
For use only in the following states: Iowa, Minnesota, North Dakota, South Dakota, Wisconsin, north of Highway 136 in Illinois, and north of Highway 91 in Nebraska.
Sortie may be used in fall applications to control weeds in minimum tillage or no-till corn or soybean production systems planted the following spring. Apply up to 21 fl. ozs./A of Sortie to medium-texture and fine-texture soils with greater than 2.5% organic matter.
Fall applications must be made after October 1. Apply Sortie in the fall after crop harvest when soil temperature at the 4-inch depth is sustained at less than 55º F and before the ground freezes.
Tillage operations may be conducted before or after applying Sortie. If following an application, tillage should be no more than 2 to 3 inches deep to uniformly incorporate the herbicide into the upper soil surface. If a sequential application program (fall application followed by spring application of Sortie) is used, the maximum combined rate of Sortie that may be applied is 21 fl. ozs./A per crop season.
Aerial Application Method and Equipment
Water Volume. Use 2 or more gallons of water per acre. The actual minimum spray volume per acre is determined by the spray equipment used. Use adequate spray volume to provide accurate and uniform distribution of spray particles over the treated area and to avoid spray drift.
Managing Spray Drift from Aerial Application
Applicators must follow these requirements to avoid off-target drift movement:
- Boom Length – The distance of the outermost nozzles on the boom must not exceed 3/4 the length of the wingspan or rotor.
- Nozzle Orientation – Nozzles must always point backward parallel with the airstream and never be pointed downward more than 45 degrees.
- Application Height – Without compromising aircraft safety, application should be made at a height of 10 feet or less above the crop canopy or tallest plants.
Applicators must follow the most restrictive use cautions to avoid drift hazards, including those found in this labeling as well as applicable State and local regulations and ordinances.
Ground Application (Banding)
When applying Sortie by banding, determine the amount of herbicide and water volume needed using the given formula in the label.
Ground Application (Broadcast)
Water Volume. Use 5 or more gallons of water per acre. The actual minimum spray volume per acre is determined by the spray equipment used. Use adequate spray volume to provide accurate and uniform distribution of spray particles over the treated area and to avoid spray drift.
Ground Application (Dry Bulk Fertilizer)
Sortie herbicide may be impregnated or coated onto dry bulk granular fertilizer carriers for preplant surface, preplant incorporated, or preemergence application. Impregnation or coating may be conducted by either the in-plant bulk system or the on-board system. When impregnated onto some dry fertilizer blends, Sortie may exhibit a strong odor. Perform the mixing operation in a well-ventilated area.
Sortie may also be applied in herbicide tank mixes where the tank mix companion product is also registered for these application systems. Individuals or agents selling Sortie in these application systems are responsible for following all State and local regulations regarding fertilizer and herbicide blending.
Addition of a drying agent may be necessary if the fertilizer and herbicide blend is too wet for uniform application because of high humidity, high urea concentration, or low fertilizer use rate. Slowly add the drying agent to the blend until a flowable mixture is obtained. Drying agents are not recommended for use with on-board impregnation systems.
Under some conditions, fertilizer impregnated with Sortie may clog air tubes or deflector plates on pneumatic application systems. Mineral oil may be added to Sortie before blending with fertilizer to reduce plugging. DO NOT use drying agents when mineral oil is used. To avoid separation of Sortie and mineral oil mixes in cold temperatures, either keep mixture heated or agitated prior to blending with fertilizer. Mineral oil may be used at inplant blending stations or on-board injection systems.
Apply 200 to 750 pounds of the fertilizer and herbicide blend per acre. Application must be made uniformly to the soil to prevent possible crop injury and for satisfactory weed control. Impregnated fertilizer spread at 1/2 rate and overlapped to obtain a full rate will offer a more uniform distribution. For granular fertilizer application to protect small birds and mammals, soil incorporation of the granules is required. A shallow (1 to 2 inches) incorporation is desirable for improved weed control. Deeper incorporation may result in unsatisfactory weed control.

Dry Bulb Onions, Garlic, Dry Bulb Shallots
Sortie may be used as part of a weed management program in dry bulb onions, garlic, and dry bulb shallots grown in muck soils, high organic soils, and in mineral soils.
Apply Sortie after dry bulb onions, garlic, and dry bulb shallots have reached the 2 true-leaf stage until a minimum of 30 days before harvest. Application made prior to 2 true-leaf stage may result in significant crop injury including possible stand reduction. If applications are made to transplanted dry bulb onions, garlic, and dry bulb shallots, DO NOT apply until transplants are in the ground and soil has settled around transplants with several days to recover.
Sortie may be applied in a single application of up to 21 fl. ozs./A or used in split applications of 10 to 14 fl. ozs./A of Sortie applied initially, and the remaining 7 to 10 fl. ozs./A of Sortie in the sequential application. If split applications are made, maintain a minimum of 14 days between sequential applications. DO NOT apply more than a total of 21 fl. ozs./A of Sortie in a single growing season.
A total maximum combined rate of 21 fl. ozs./A of Sortie may be applied on any soil type in a single growing season.
The maximum Sortie use rates in a single application are 12 to 18 fl. ozs./A on coarse-texture soils and 18 to 21 fl. ozs./A on medium-texture or fine-texture soils, but are also influenced by soil organic matter content.
