5 Product Information Zidua® SC herbicide is a selective rate-dependent resid- ual pr eemergence herbicide for controlling annual grass weeds, sedges, and annual broadleaf weeds (including bio types resistant to ACCase inhibitors, ALS inhibitors, and glyphosate) that infest broad bean, celery, chickpea, corn, cotton, dry bulb onions, fallow, leek, mint, peanut, perenni- al cool- se ason grasses grown for seed production, potato, safflower, soybean, and sunflower listed in Table 1 and wheat listed in Table 2 . R efer to Crop -specific Inf ormation section for use directions specific to each labeled crop . P eriods of dry weather following application of Zidua SC may reduce herbicidal effectiveness . Z idua SC must be activated by at least 1/2 inch of rainfall or irrigation before weed germination and emergence . When Zidua SC is not activated and weeds emerge, a labeled postemergence herbicide or shallow cultivation may be needed to control weed escapes . Z idua SC does not control emerged weeds . He rbicidal activity of Zidua SC may be reduced if trash on the soil surface from the previous crop covers more than 25% of the application area . M anage trash levels if needed with combine straw shredder/spreaders, earlier burndown of emerged weeds, or light tillage . Ta ble 1.

Even though Zidua SC will control these species, some weed escapes are possible . Multiple herbicides with multiple different effective sites of action MUST be used in tank mix- tures or sequentially to limit these weed escapes to prevent or delay the onset of herbicide-resistant weed biotypes . 2 For control of these weeds, a tank mix partner or a sequentially applied herbicide partner is needed .
8 Mode of Action Zidua® SC herbicide acts to inhibit very long-chain fatty acid synthesis as a Group 15 herbicide . I t is a root-and- shoot growth inhibitor that controls susceptible germinating seedlings before or soon after they emerge from the soil . Herbicide Resistance Management Zidua SC is a Group 15 herbicide . An y weed population may contain or develop plants naturally resistant to Zidua SC and other Group 15 herbicides . We ed species with resistance to Group 15 may eventually dominate the weed population if Group 15 herbicides are used repeat- edly in the same field or in successive years as the primary method of control for targeted species . T his may result in partial or total loss of control of those species by Zidua SC or other Group 15 herbicides . To delay herbicide resistance consider: • Av oiding the consecutive use of Zidua SC or other t arget-site-of-action Group 15 herbicides that have a similar target site of action on the same weed species . • Usi ng tank mixes or premixes with herbicides from differ- ent target-site-of-action groups as long as the involved products are all registered for the same use, have differ- ent sites of action, and are both effective at the tank mix or prepack rate on the weed(s) of concern . • Basi ng herbicide use on a comprehensive IPM ( In tegrated Pest Management) program including cultural and mechanical methods . • Mo nitoring treated weed populations for loss of field effi- cacy, and control of escapes with effective alternative herbicides or mechanical methods . • Id entify weeds present in the field through scouting and field history and understand their biology . T he weed- co ntrol program needs to consider all of the weeds present . • Sc out fields prior to application to identify the weed spe- cies present and their growth stage to determine if the intended application will be effective . • Sc out fields after application to verify the treatment was effective . • Su spected herbicide-resistant weeds may be identified by these indicators: 1 . Fa ilure to control a weed species normally controlled by the herbicide at the dose applied, especially if con- trol is achieved on adjacent weeds; 2 . A sp reading patch of non-controlled plants of a partic- ular weed species; and 3 . Su rviving plants mixed with controlled individuals of the same species . • If resistance is suspected, treat weed escapes with an h erbicide with a different MOA and/or use non-chemical methods to remove escapes, as practical, with the goal of preventing further seed production . • Re port any incidence of non-performance of this product against a particular weed species to your local BASF representative . • Con tacting your local extension specialist, certified crop advisors, and/or manufacturer for herbicide resistance management and/or integrated weed management directions for specific crops and resistant weed biotypes . Crop Response No crop injury is expected when Zidua SC is applied according to label directions and under normal environ- mental conditions . A pplication to crops under stress because of inadequate or excess of moisture for normal crop development, cool and hot temperatures, sodic soils, poorly drained soils, hail damage, flooding, pesticide injury, mechanical injury, or widely fluctuating temperatures may result in crop injury . Application Instructions Application rates of Zidua SC may vary depending on soil texture . R efer to Table 3 for soil texture groups used in this label unless a specific soil texture is mentioned . Whe n use rates are in ranges, apply the low rate for soils with coarse texture or low organic matter; apply the high rates for fine soil textures, high organic matter, heavy soil surface plant residue, or heavy weed pressure . Ta ble 3. Soil Texture Groups Coarse Medium Fine Sand Loamy sand Sandy loam Loam Silt loam Silt Sandy clay loam Sandy clay Silty clay loam Silty clay Clay loam Clay Zidua SC may be used on peat soils and muck soils, and mineral soils with 10% or more organic matter , but weed control may be inconsistent and/or reduced . Us e maximum labeled use rate allowed in the specific crop . Use Table 4 to determine the corresponding amounts of active ingredient (pyroxasulfone) from Zidua SC product use rates .

R efer to the Crop-specific Information section for specific applica- tion instructions (timings, rates, restrictions and precautions) by crop . Pr eplant Surface Application. Apply Zidua SC alone or in tank mix within 45 days of planting . I f weeds are pres- ent at the time of application, use additional weed control methods, for example a tank mix with an appropriate po stemergence herbicide(s), to control emerged weeds . Pr eplant Incorporated (PPI) Application. Incorporate Zidua SC into the upper (1 to 2 inches) soil surface within 14 days of planting . D eeper incorporation may increase the potential for crop injury and also may result in reduced weed control . Us e appropriate equipment for uniform shal- low incorporation, including a field cultivator, harrow, rolling cultivator, or finishing disc . Pr eemergence Surface Application. After planting and before crop emergence, apply a uniform broadcast treat- ment to the soil surface . A pply Zidua SC only to a uniform seedbed which is firm and free of clods, cracks, excess trash (previous crop residue), and weed growth . I f weeds are present, apply Zidua SC in a tank mix with an appro- priate postemergence herbicide, for example a glyphosate- c ontaining product . Ea rly Postemergence Application. Zidua SC must be applied and activated before weed seedling emergence or in a tank mixture that controls emerged weeds . Zidua SC will not control emerged weeds . W eeds that are already emerged at the time of application must be controlled with cultivation, tank mix or sequential application of another herbicide labeled for postemergence control of the target weeds in the crop . Po stemergence-directed (Layby) Application. Zidua SC must be applied as a directed spray between crop rows and activated before weed seedling emergence or in a tank mix that controls emerged weeds . Z idua SC will not control emerged weeds . W eeds that are already emerged at the time of application must be controlled with cultivation, tank mix or sequential application of another herbicide labeled for postemergence control of the target weeds in the crop . Fal l/Winter Application for controlling weeds germi - nating in the fall, or winter weeds. Zidua SC may be broadcast surface applied in the fall or winter after crop harvest . D O NOT apply to frozen or snow-covered soil . T illage operations may be conducted before or after apply- ing Zidua SC . I f tillage is used following an application, tillage must be shallow (no more than 2-inches deep) to uniformly incorporate the herbicide into the upper soil surface . Application Methods and Equipment Zidua SC may be applied by aerial or ground application or by chemigation application via sprinkler or drip irrigation . Th orough spray coverage is required for optimum weed control and can be improved with proper nozzle and spray volume selection . Us e and configure application equip- ment to provide an adequate spray volume, an accurate and uniform distribution of spray droplets over the treated area . Adj ust equipment to maintain continuous agitation during spraying with good mechanical or bypass agitation . Av oid overlaps that will increase rates above the use rates specified in this label .

10 Mandatory Spray Drift Management Aerial Applications • DO NOT release spray at a height greater than 10 ft a bove the vegetative canopy, unless a greater applica- tion height is necessary for pilot safety . • For all applications, applicators are required to use a medium to ultra coarse spray droplet size (ASABE S572 .1) . • Th e boom length must not exceed 65% of the wing- span for airplanes or 75% of the rotor blade diameter for helicopters . • Ap plicators must use 1/2 swath displacement upwind at the downwind edge of the field . • No zzles must be oriented so the spray is directed toward the back of the aircraft . • DO N OT apply when wind speeds exceed 10 miles per hour at the application site . • DO N OT apply during temperature inversions . Ground Applications • Apply with the nozzle height advised by the manufac- t urer, but no more than 3 feet above the ground or crop canopy . • For all applications, applicators are required to use a medium to ultra coarse spray droplet size (ASABE S572 .1) . • DO N OT apply when wind speeds exceed 10 miles per hour at the application site . • DO N OT apply during temperature inversions . Spray Drift Advisories The applicator is responsible for avoiding off-site spray drift . B e aware of nearby non-target sites and environmen- tal conditions . Importance of Droplet Size An effective way to reduce spray drift is to apply large droplets . Us e the largest droplets that provide target pest control . W hile applying larger droplets will reduce spray drift, the potential for drift will be greater if applications are made improperly or under unfavorable environmental conditions . Controlling Droplet Size - Ground Boom Volume Volume. Increasing the spray volume so that larger drop- lets are produced will reduce spray drift . Us e the highest practical spray volume for the application . I f a greater spray volume is needed, consider using a nozzle with a higher flow rate . Pr essure. Use the lowest spray pressure advised for the nozzle to produce the target spray volume and droplet size . Spra y Nozzle. Use a spray nozzle that is designed for the intended application . Con sider using nozzles designed to reduce drift . Controlling Droplet Size - Aircraft Adjust Nozzles Follow nozzle manufacturers directions for setting up noz- zles . G enerally, to reduce fine droplets, nozzles must be oriented parallel with the airflow in flight . Boom Height - Ground Boom Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage . F or ground equipment, the boom must remain level with the crop and have minimal bounce . Release Height - Aircraft Higher release heights increase the potential for spray drift . Wh en applying aerially to crops, DO NOT release spray at a height greater than 10 feet above the crop canopy, unless a greater application height is necessary for pilot safety . Shielded Sprayers Shielding the boom or individual nozzles can reduce spray drift . C onsider using shielded sprayers . V erify that the shields are not interfering with the uniform deposition of the spray on the target area . Temperature and Humidity When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation . Temperature Inversion Drift potential is high during a temperature inversion . T em- perature inversions are characterized by increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind . T he presence of an inversion can be indicated by ground fog or by the movement of smoke from a ground source or an aircraft smoke generator . S moke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing . Av oid applica- tions during temperature inversions . Wind Drift potential generally increases with wind speed . AVOID APPLICATIONS DURING GUSTY WIND CON DITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect spray drift . Chemigation Application via Sprinkler and Drip Irrigation Systems Zidua® SC herbicide may be applied as a chemigation treatment through sprinkler irrigation systems . Appl y this product ONLY through a sprinkler irrigation system of the following type: center pivot, end tow, hand move, lateral move, side (wheel) roll, or solid set . DO NOT apply this product through any other type of sprinkler irrigation system . Zi dua SC may also be applied as a chemigation treatment through drip irrigation systems . Al l chemigation precau- tions mentioned in this label for sprinkler irrigation systems also apply for drip irrigation systems .
11 Application may be made alone or in tank mixtures with other herbicides on this label registered for use in specified sprinkler or drip irrigation systems . Appl ication must be made within specific crop stage timings and product use rates given in the container label Directions For Use . Uni form distribution of Zidua® SC herbicide -treated ir rigation water is the sole responsibility of the applicator and is required to avoid crop injury, lack of herbicide effec- tiveness, or illegal pesticide residue in the crop . I f you have questions about calibration, contact State Extension Ser - vice specialists, equipment manufacturers, or other experts . Pr oper calibration is the responsibility of the applicator . T he system must be properly calibrated (with water only) to ensure the amount of Zidua SC applied corresponds to the specified rate . A pply Zidua SC in volume minimums of 0 .33 t o 0 .67 i nch of water using the lower volume for coarse- te xture soils and the higher volume for fine-texture soils . A pplication made in high volumes of water (more than 1 inch) may result in reduced weed control . Me ter herbicide dilution into irrigation water through the entire time of water application for center pivot and lateral move sprinkler systems . F or solid-set and hand-move sprinkler irrigation systems and drip irrigation systems, apply Zidua SC through the system at the beginning of the set; then follow with additional water to reach volume minimums as listed by soil type . T o increase calibration accuracy of injection metering equipment, dilute Zidua SC in a minimum of 3 parts water to 1 part Zidua SC . Main- t ain agitation in injection nurse tanks to keep a uniform herbicide suspension during application . Special Restrictions for Chemigation: 1 . DO NOT a pply when wind speed favors drift beyond the area intended for treatment . 2 . DO NOT connect an irrigation system used for pesticide application to a public water system unless the pesticide label-prescribed safety devices for public water systems are in place . 3 . A pe rson knowledgeable of the chemigation system and responsible for its operation, or under the supervision of the responsible person, shall shut the system down and make necessary adjustments if the need arises . 4 . Ta il water (runoff water) from chemigation that contains Zidua SC needs be recirculated and/or contained in the field in a cistern or holding reservoir from the initial appli- cation and/or used only on adjacent, approved crops for which Zidua SC is registered for this type of application . 5 . The pesticide injection pipeline must contain a function - al, automatic, quick-closing check valve to prevent the flow of fluid back toward the injection pump . I t must also contain a functional, normally closed, solenoid-operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down . 6 . Th e sprinkler chemigation system must contain a func- tional check valve, vacuum-relief valve, and low-pressure drain appropriately located on the irrigation pipeline to prevent water-source contamination from backflow . I n addition, systems must use a metering pump, including a positive displacement injection pump (e .g . di aphragm pump) effectively designed and con - structed of materials that are compatible with pesticides and capable of being fitted with a system interlock . 7 . The sprinkler chemigation system must contain function - al interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops, or in cases where there is no water pump, when the water pressure decreases to the point where pesti- cide distribution is adversely affected . 8 . Th e irrigation line or water pump must include a func- tional pressure switch that will stop the water pump motor when the water pressure decreases to the point where pesticide distribution is adversely affected . Chemigation systems connected to public water systems: 1 . Public water system means a system for the provision to t he public of piped water for human consumption if such system has at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 60 days out of the year . 2 . Chem igation systems connected to public water sys- tems must contain a functional, reduced-pressure zone backflow preventer (RPZ) or the functional equivalent in the water supply line upstream from the point of pesti- cide introduction . A s an option to the RPZ, the water from the public water system needs be discharged into a reservoir tank prior to pesticide introduction . Th ere shall be a complete physical break (air gap) between the outlet end of the fill pipe and the top or overflow rim of the reservoir tank of at least twice the inside diameter of the fill pipe . 3 . Al l chemigation systems connected to public water sys- tems must also follow restrictions listed in the preceding section . Ground Application (Dry Bulk Fertilizer) Zidua SC may be impregnated or coated onto dry bulk granular fertilizer carriers for residual soil surface (fall, pre- plant surface, preplant incorporated) applications or for residual weed control from postemergence over-the-top of cotton applications . Im pregnation or coating may be con- ducted by in-plant bulk or on-board systems . P erform the mixing operation in well-ventilated areas . Al l individual state regulations relating to dry bulk granular fertilizer blending, registration, labeling, and application are the responsibility of the individual and/or company selling the herbicide/fertilizer mixture . Zi dua SC may be impregnated on many commonly used dry fertilizers . DO NOT impregnate on ammonium nitrate, fertilizers containing ammonium nitrate, potassium nitrate, sodium nitrate, or powdered limestone .
12 Fertilizer application rates of at least 200 lbs to 700 lbs per acre of herbicide and fertilizer blend will provide adequate distribution or coverage of Zidua ® SC herbicide across the soil surface . A pplication of impregnated fertilizer must be made uniformly to the soil to prevent possible crop inju- ry and offer satisfactory weed control . I mpregnated fertilizer spread at half rate and overlapped to obtain a full rate offers a more uniform distribution . A s hallow (less than 2 inches) incorporation is desirable for improved weed control . D eeper incorporation dilutes the herbicide layer near the soil surface and may result in unsatisfactory weed c ontrol . To c alculate the herbicide rate when using dry bulk fertiliz- er applications: [fl ozs of Zidua SC per acre X 2000] = fl ozs of Zidua SC for 1 ton of fertilizerpounds fertilizer per acre To impregnate Zidua SC on bulk fertilizer, use a closed ro tary-drum mixer or other commonly used dry bulk fertil - izer blender equipped with suitable spray equipment . Mi x Zidua SC with sufficient water to form a sprayable slurry mixture . S pray nozzles must be directed to provide uni- form fertilizer coverage while avoiding spray contact with mixing equipment . No nuniform impregnation can cause crop injury or unsatisfactory performance . Spra y herbicide mixture onto fertilizer after blending has started . A ddition of a suitable drying agent may be necessary if the fertilizer and herbicide blend is too wet for uniform application due to high humidity, high urea concentration, or low fertilizer use rate . S lowly add the drying agent to the blend until a flowable mixture is obtained . D rying agents are not intend- ed for use with on-board impregnation sy stems . Und er some conditions, fertilizer impregnated with Zidua SC may clog air tubes or deflector plates on pne umatic application systems . Mine ral oil may be added to Zidua SC before blending with fertilizer to reduce plug- ging . D O NOT use drying agents when mineral oil is used . T o avoid separation of Zidua SC and mineral oil mixes in cold temperatures, keep mixture heated or agitated before blending with fe rtilizer . M ineral oil may be used with inplant blending stations or with on-board injection systems . Un iformly apply the treated fertilizer with accurately cali- brated and proper equipment immediately after impregnation to avoid lump formation and spreading d ifficulties . Ac curate calibration of fertilizer application equipment and uniform fertilizer distribution is essential for satisfactory weed control . Cleaning Spray Equipment Clean application equipment thoroughly by using a strong detergent or commercial sprayer cleaner according to the manufacturer’s directions . Tr iple rinse the equipment before and after applying Zidua SC . Additives Zidua SC is formulated to provide optimal residual pre- emergence weed control . H owever, several tank mixes with Zidua SC may require an adjuvant to improve burn- down of emerged weeds . T herefore, an adjuvant may be used with Zidua SC tank mixes that are applied fall, pre- plant, pr eemergence, or early postemergence . F ollow the adjuvant directions for the tank mix pa rtner of Zidua SC . Tank Mixing Information It is the pesticide user’s responsibility to ensure that all products in the mixtures are registered for the intended use . Re ad and follow the applicable restrictions and limita - tions and directions for use on all product labels involved in tank mixing . Us ers must follow the most re strictive direc- tions for use and precautionary statements of each product in the tank mixture . Zi dua SC may be tank mixed or applied sequentially with other herbicide products registered for use in any labeled crop found in this label for a broader spectrum of residual weed control and/or control of emerged weeds . R efer to the tank mix product labels to confirm that the respective tank mix products are registered for use on the labeled crop . F ollow the adjuvant directions for the tank mix part- ner of Zidua SC . R ead and follow tank mix product labels for application instructions, use restrictions and precau - tions, and rotational cropping guidance . Ph ysical incompatibility, reduced weed control, or crop injury may result from mixing Zidua SC with other pesti - cides, additives, or fertilizers . Compatibility Test for Tank Mix Products Before mixing components, always perform a compatibility jar test . 1 . Fo r 20 gallons per acre spray volume, use 3 .3 cu ps (800 mL) of water . F or other spray volumes, adjust rates accordingly . O nly use water from the intended source at the source temperature . 2 . Ad d components in the sequence indicated in the mix- ing order using 2 teaspoons for each pound or 1 teaspoon for each pint of label rate per acre . 3 . Al ways cap the jar and invert 10 cycles between com- ponent additions . 4 . Wh en the components have all been added to the jar, let the solution stand for 15 minutes . 5 . Ev aluate the solution for uniformity and stability . T he spray solution must not have free oil on the surface, or fine particles that precipitate to the bottom, or thick (clabbered) texture . I f the spray solution is not compati- ble, repeat the compatibility test with the addition of a suitable compatibility agent . I f the solution is then co mpatible, use the compatibility agent as directed on its label . I f the solution is still incompatible, DO NOT mix the ingredients in the same tank .
13 Mixing Order Shake Zidua® SC herbicide container well before use. Maintain agitation throughout mixing and application until spraying is completed . 1 . W ater - Fill tank 1/2 to 3/4 full with clean water and start agitation . 2 . In ductor - If an inductor is used, rinse it thoroughly after each component has been added . 3 .

Residual Rates of Zidua SC in Sunflower Application Timing Use Rate by Soil Texture1 (fl ozs/A) Coarse Medium Fine Preplant surface 1 .75 t o 2 .5 2 .5 to 5 .0 5 .0 t o 6 .5 P reemergence 1 .75 t o 2 .5 2 .5 to 5 .0 5 .0 t o 6 .5 E arly postemergence 1 .75 t o 2 .5 1 .75 t o 3 .25 1 .75 t o 3 .25 1 Refer to Table 3 for definition of soil-texture groups . Application Timing Zidua SC may be applied in a single application or in sequential applications . Fall/Winter Application for controlling weeds germinating in the fall, or winter annual weeds. Zidua SC may be broadcast surface applied in the fall or winter to control winter annual weeds and other weeds germinating in the fall . Us e on coarse, medium, or fine soils at rates listed for the preplant surface timing . S equential preemergence and/or postemergence applications can be made, but DO NOT exceed the maximum cumulative rate allowed by soil type per year . S ee the main Application Timings section of this label for further application instructions . Early Preplant Surface Application (within 15 to 45 days of planting) Use application rates in Table 18 when making preplant surface applications, using the highest application rate within the rate range for a given soil texture . P replant sur- face applications are not advised on coarse soils or in areas where average annual rainfall (or rainfall plus irriga- tion) typically exceeds 40 inches . Preplant Surface Application (within 14 days of planting) Apply Zidua SC at the use rates specified in Table 18 as a broadcast spray to the soil surface before planting on all soil types . Preemergence Surface Application Apply Zidua SC at use rates specified in Table 18 as a broadcast spray to the soil surface after planting and before crop emergence . Early Postemergence Application Apply Zidua SC at use rates specified in Table 18 as a broadcast spray to sunflower from first true leaf (leaf at least 1 .5 in ches long, V1 stage) through eight leaf stage (V8) . Z idua SC applications to emerged sunflower may result in temporary leaf burn and stunting, but a reduction in sunflower yield is unexpected . Ad juvants may be applied with Zidua SC when making early postemergence applications . Sequential Applications If a sequential application program of Zidua SC is used (e .g . f all application followed by spring application, or sequential spring applications including preplant surface or preemergence application followed by postemergence application or consecutive postemergence applications), the maximum combined rate of Zidua SC that may be applied per year is 2 .5 fl oz s/A (0 .08 l b ai/A of py roxasulfone) on coarse soils and 8 .25 fl o zs/A (0 .26 6 lb ai/A of pyroxasulfone) on medium-to-fine soils . Crop-specific Restrictions • On coarse soil - DO NOT apply more than 2 .5 fl oz s/A of Zidua SC (0 .08 l b ai/A of pyroxasulfone) in a single applica ti on or as a maximum cumulative amount from sequential applications in sunflower per year . • On a ll soils other than coarse:
- DO N OT apply more than 6 .5 fl oz s/A of Zidua SC (0 .21 3 lb ai/A of pyroxasulfone) in a single application .
- DO N OT apply more than a maximum cumulative amount of 8 .25 fl o zs/A of Zidua SC (0 .26 6 lb ai/A pyroxasulfone) from sequential applications in sunflow- er per year . • Ma ximum number of applications per year: 3 (when applying rates less than single application maximum rate) • Se parate sequential applications by at least 14 days . • D O NOT apply Zidua SC preplant incorporated to sunflower . • D O NOT apply Zidua SC to sunflower at cracking or cotyledon stage . • D O NOT apply a tank mix of Zidua SC and Beyond ® h erbicide on Clearfield ® sunflower hybrids/varieties . • Th ere is no required (preharvest) interval between a pre- plant and preemergence application of Zidua SC and sunflower harvest .
25 • DO NOT apply Zidua ® SC herbicide postemergence less than 60 days before harvest of sunflower seed . Crop-specific Precautions • Sunflower seed quality - P lant high quality seed . • S eedbed preparation - The seedbed MUST be pre- pared to ensure good seed row closure and soil coverage of the seed . • Th e use of Zidua SC may result in temporary growth suppression or leaf burn in sunflower under stressful conditions including inadequate or excessive soil mois - ture or rainfall, cool and hot temperatures, compacted or crusted soils, improper planting depth, injury from other pesticides, disease or other pest damage, mechanical injury, nutrient imbalances, or other conditions known to cause plant stress . • I f Zidua SC is tank mixed with another herbicide other than glyphosate or a graminicide, use a lower rate within the Zidua SC rate range for the application timing and soil texture (as specified in Table 18) . Wheat Zidua SC may be applied preplant surface, pre- emergence, delayed preemergence, or early postemergence in fall-seeded or spring-seeded wheat for residual preemergence control or suppression of listed weeds (Table 2 ) and suppression of other listed weeds (Table 1 ) . Us e Zidua SC as part of a weed control pro- gram in wheat either in combination or sequentially with other herbicides for a broader spectrum of weed control and/or control of emerged weeds . Crop Response Zidua SC applied preplant surface or preemergence can cause wheat injury . Und er stressful conditions (including inadequate or excessive moisture, cool or hot tempera- tures, compacted soils, injury from other pesticides, disease or other pest damage, mechanical injury, nutrient imbalances, low soil pH induced aluminum toxicity, or other conditions known to cause plant stress), Zidua SC injury will be intensified . No c rop injury is expected when Zidua SC is applied delayed pr eemergence or early postemergence . Ho wever, some visual wheat response is possible when Zidua SC is applied to wheat under stressful conditions including inad - equate or excessive moisture, cool or hot temperatures, compacted soils, injury from other pesticides, disease or other pest damage, mechanical injury, nutrient imbalanc - es, or other conditions known to cause plant stress . Wh eat response is most often visible as stunting and/or discoloration of leaf tissue (e .g . c hlorosis), but in its most severe form can result in stand loss and yield reduction . T he greatest potential for wheat response occurs when Zidua SC concentrates in the crop row . U nacceptable wheat response may be caused by uneven application, soil clods or disturbances, an open/cracked seed furrow that allows herbicide to directly contact the seed, or a deep seed furrow that allows herbicide concentration after a rain/irrigation event during wheat germination . C ertain wheat varieties can be more sensitive to Zidua SC . B efore applying to wheat, verify sensitivity with your local seed company (supplier), university extension specialist (e .g . w heat breeder, weed scientist, county agent, etc .), or BASF representative . Application Rate Apply Zidua SC in wheat at the residual rates in Table 19 . Ta ble 19. Residual Rates of Zidua SC in Wheat Application Timing Use Rate by Soil Texture1 (fl ozs/A) Coarse Medium Fine Preplant surface or Preemergence 1 .0 t o 2 .0 1 .75 t o 2 .5 1 .75 t o 3 .0 De layed preemergence 1 .25 t o 1 .75 1 .75 t o 2 .5 1 .75 t o 3 .25 Ea rly postemergence 1 .75 t o 4 .0 1 .75 t o 4 .0 1 .75 t o 4 .0 1 Refer to Table 3 for definition of soil-texture groups .

Preplant Surface Application Apply Zidua SC at the use rates specified in Table 19 as a broadcast spray to the soil surface no more than 14 days before planting on all soil types . S oil disturbance after application from planters/drills may result in herbicide incorporation that can result in unacceptable crop injury, or displacement of Zidua SC that can result in inconsistent weed control . S ee State-specific Use Instructions for applications in Idaho, Montana, Oregon, and Washington . Preemergence Surface Application Apply Zidua SC at the use rates specified in Table 19 after planting but before wheat spiking as a broadcast spray to the soil surface with uniform seedbed that is firm and free of clods . E nsure good seed row closure and soil coverage to avoid contact with Zidua SC . A s the interval from planting to application increases, the potential for crop injury decreases . S ee State-specific Use Ins tructions for applications in Idaho, Montana, Oregon, and Washington . Delayed Preemergence Surface Application Apply Zidua SC at the use rates specified in Table 19 as a broadcast spray to the soil surface following wheat plant- ing when 80% of germinated wheat seeds have a shoot at least 1/2-inch long until wheat sp iking .
26 Early Postemergence Application Apply Zidua® SC herbicide at the use rates specified in Table 19 as a broadcast spray to wheat at spiking up to the 4th-tiller growth stage .
