General Information

General Information

Integrity herbicide is a selective residual preemergence herbicide for controlling most annual grasses, broadleaf weeds, and sedges in field corn and popcorn (refer to Table 1 of the label for a list of weeds controlled preemergence). Residual preemergence applications of Integrity must be activated by at least 1/2 inch of rainfall or sprinkler irrigation prior to weed seedling emergence. When Integrity is not activated, a labeled postemergence herbicide or cultivation may be needed to control weed escapes.

Integrity also provides contact burndown of many broadleaf weeds (refer to Table 2 of the label for a list of weeds controlled by a burndown application). An adjuvant (refer to Additives section for details) is required with Integrity for optimum broadleaf burndown activity. Burndown applications of Integrity should be made when broadleaf weeds are small and actively growing. Burndown activity may be slowed or reduced under cloudy and/or foggy or cooler weather conditions, or when weeds are growing under drought or other stress conditions. When targeting dense weed populations and/or larger broadleaf weeds, use a higher application rate within an application rate range and/or higher spray volumes. Angling nozzles forward (to 45 degrees) may improve penetration of denser weed canopies.

Mode of Action

Integrity herbicide combines the two active ingredients: saflufenacil, a potent inhibitor of protoporphyrinogenoxidase belonging to herbicide mode-of-action Group 14 (WSSA)/Group E (HRAC), and dimethenamid-P, a chloroacetamide belonging to the herbicide mode-of-action Group 15/Group K3. Saflufenacil is rapidly absorbed by roots and foliage. Following inhibition of the protoporphyrinogen-oxidase, plant death is the result of membrane damage. Under active growing conditions, susceptible emerging weed seedlings usually develop chlorotic and necrotic injury symptoms within hours and die within a few days. Susceptible germinating weed seeds will usually die as they reach the soil surface or shortly after emergence. Dimethenamid-P is a root-and-shoot inhibitor that controls susceptible weed seedlings before or soon after they emerge from the soil.

Crop Tolerance

Field corn and popcorn are tolerant to Integrity when applied according to label directions as a preplant to preemergence treatment and under normal environmental conditions. Crop injury may occur under stressful growing conditions (e.g. low soil fertility, seedling disease, extreme hot or cold weather, excessive moisture, high soil pH, high soil salt concentration, or drought). Severe crop injury will result if Integrity is applied postemergence (over the top) to corn.

Application Instructions

Integrity may be applied preplant surface, preplant incorporated or preemergence to field corn and popcorn. Integrity may only be applied prior to crop emergence.

Application Rates

Application rates of Integrity for residual preemergence weed control may vary depending on soil texture and organic matter. Refer to Table 3 for soil texture groups used in the label.

Application Methods and Equipment

Integrity may be applied by either ground or air. Good spray coverage is important for optimum weed control and can be improved with proper adjuvant, nozzle, and spray volume selection.

Use and configure application equipment to provide an adequate spray volume, an accurate and uniform distribution of spray droplets over the treated area, and to avoid spray drift to nontarget areas. Equipment should be adjusted to maintain continuous agitation during spraying with good mechanical or bypass agitation. Avoid overlaps that will increase rates above the use rates specified in the label.

Integrity may be applied using either water or sprayable fluid nitrogen fertilizer solutions as the spray carrier. Additionally, Integrity may be impregnated on and applied with dry bulk fertilizer.

Aerial Application Requirements

Water Volume. Use 3 or more gallons of water per acre. See the section of the label for the measures to be followed to reduce the potential of spray drift to nontarget areas from aerial applications.

Ground Application Requirements

Spray Carrier Volume. Use 3 or more gallons of water per acre or 20 or more gallons of sprayable fluid fertilizer per acre. Thorough coverage of existing vegetation is essential for burndown applications and higher spray volumes may be necessary for better performance.

Ground Application (dry bulk fertilizer)

Integrity herbicide may be impregnated or coated onto dry bulk granular fertilizer carriers for residual soil surface applications. Impregnation or coating may be conducted by either in-plant bulk or on-board systems. Perform the mixing operation in well-ventilated areas.

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 Integrity may clog air tubes or deflector plates on pneumatic application systems. Mineral oil may be added to Integrity before blending with fertilizer to reduce plugging. DO NOT use drying agents when mineral oil is used. To avoid separation of Integrity 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.

Generally fertilizer application rates of at least 200 lbs to 700 lbs per acre of herbicide and fertilizer blend will provide adequate distribution or coverage for Integrity across the soil surface. Application must be made uniformly to the soil to prevent possible crop injury and offer satisfactory weed control. Impregnated fertilizer spread at 1/2 rate and overlapped to obtain a full rate will offer a more uniform distribution. A shallow (< 2 inches) incorporation is desirable for improved weed control. Deeper incorporation will dilute the herbicide layer near the soil surface and may result in unsatisfactory weed control.

Use the formula in the label to determine the herbicide rate when using dry bulk fertilizer applications.

Use Precautions

- Maximum seasonal use rate - DO NOT apply more than a maximum cumulative amount of 25 fl ozs/A of Integrity per cropping season. A cropping season is defined as the period following harvest of the preceding crop through the harvest of the planned or current crop.

- If additional saflufenacil is applied, DO NOT exceed a maximum cumulative amount of 0.134 lb ai/A saflufenacil per cropping season.

- If additional dimethenamid-P is applied, DO NOT exceed a maximum cumulative amount of 0.98 lb ai/A dimethenamid-P per cropping season.

- DO NOT apply Integrity after crop emergence because severe crop injury will occur.

- DO NOT apply Integrity where an at-planting application of organophosphate or carbamate insecticide(s) is planned and/or has occurred because severe injury may result.

- Rainfastness - Integrity is rainfast 1 hour after application. Burndown activity may be reduced if rain or irrigation occurs within 1 hour of application.

- DO NOT contaminate irrigation ditches or water used for domestic purposes.

- Integrity herbicide is not for sale, distribution, or use in Nassau and Suffolk counties in New York State.

For distribution and use only in the state of South Dakota

Refer to the Integrity herbicide main label, EPA Reg. No. 7969-279, for complete Directions For Use and all applicable restrictions and precautions. When following the instructions on this supplemental label, the user must have the label and the entire Integrity container label in possession at the time of pesticide application.

Limitations, Restrictions, and Exceptions

Grain Sorghum

Integrity may be applied preplant surface, preplant incorporated, or preemergence to grain sorghum. All Integrity applications must only be made to sorghum seed that has been properly treated by the seed company with an approved chloroacetamide herbicide safener or severe injury may occur.

Under high soil moisture and/or cool conditions, Integrity application may cause temporary stunting or leaf wrapping of grain sorghum. Grain sorghum will normally outgrow these symptoms within 10 to 14 days.

NOTES:

- Application rate will eliminate early season weed interference. Full season weed control will require a labeled tank mix partner, sequential postemergence herbicide application, and/or cultivation.

Application Timings

Preplant Surface and Preplant Incorporated Applications (up to 14 days prior to planting)

Integrity can be applied to the soil surface or incorporated up to 14 days before planting. For preplant incorporated applications, apply Integrity and incorporate into the upper soil surface (1 to 2 inches). Use a harrow, rolling cultivator, field cultivator, or other implement capable of providing uniform shallow incorporation. Avoid deeper incorporation or reduced weed control may result.

Preemergence Surface Application

Apply Integrity as a broadcast treatment to the soil surface after planting and before crop emergence. Integrity must be applied before crop emergence or severe injury will occur.

Crop-specific Restrictions and Limitations

- DO NOT apply Integrity after grain sorghum emergence or severe crop injury will occur.

- DO NOT apply Integrity where an at-planting application of an organophosphate or carbamate insecticide(s) is planned and/or has occurred or severe injury may result.

- DO NOT apply more than a maximum cumulative amount of 0.112 lb of saflufenacil per acre from all product sources per cropping season.

- Integrity is not registered for use on sweet or forage sorghum.

- Sorghum forage and silage can be harvested, fed, or grazed 70 or more days after application.

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.
