GRAIN SORGHUM - CO, KS - PREPLANT, PREEMERGENCE SURFACE APPLIED
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.
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.
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 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.
