General Information


Mode of Action
UP-STAGE 3CS herbicide contains the active ingredient clomazone, an isoxazolidinone herbicide, which acts to inhibit pigment synthesis in the plant chloroplast as a Group 13 herbicide. It is quickly taken up by the roots and shoots to block plant chlorophyll to control susceptible germinating seedlings before or soon after they emerge from the soil.

Any weed population may contain or develop plants naturally resistant to UP-STAGE 3CS and other Group 13 herbicides. Weed species with acquired resistance to Group 13 may eventually dominate the weed population if Group 13 herbicides are used repeatedly in the same field. Appropriate resistance-management strategies should be followed.

To delay herbicide resistance take one or more of the following steps:

- Rotate the use of UP-STAGE 3CS or other Group 13 herbicides within a growing season sequence or among growing seasons with different herbicide groups that control the same weeds in a field. Whenever possible incorporate multiple weed control practices such as mechanical cultivation, biological management practices, and crop rotation.

- Use tank mixtures with herbicides from a different group if such use is permitted; where information on resistance in target weed species is available, use the less resistance-prone partner at a rate that will control the target weed(s) equally as well as the more resistance-prone partner. Consult your local extension service or certified crop advisor if you are unsure as to which active ingredient is currently less prone to resistance.

- Adopt an integrated weed-management program for herbicide use that includes scouting and uses historical information related to herbicide use and crop rotation, and that considers tillage (or other mechanical control methods), cultural (e.g. higher crop seeding rates; precision fertilizer application method and timing to favor the crop and not the weeds), biological (weed-competitive crops or varieties) and other management practices.

- Fields should be scouted before and after application to identify the weed species present and their growth stage to determine if the intended application will be effective. Scout after herbicide application to monitor weed populations for early signs of resistance development. Indicators of possible herbicide resistance include: (1) failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; (2) a spreading patch of non-controlled plants of a particular weed species; (3) surviving plants mixed with controlled individuals of the same species. If resistance is suspected, prevent weed seed production in the affected area by an alternative herbicide from a different group or by a mechanical method such as hoeing or tillage. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and planting clean seed.

- If a weed pest population continues to progress after treatment with this product, discontinue use of this product and switch to another management strategy or herbicide with a different mode of action (MOA), if available. Treat weed escapes with an herbicide with a different MOA or use nonchemical methods to remove escapes. To the extent possible do not allow weed escapes to produce seeds, roots, or tubers.

- Contact your local extension specialist, certified crop advisors, and/or manufacturer for additional herbicide resistance management and/or integrated weed management recommendations for specific crops and resistant weed biotypes. Report any incidence of non-performance of this product against a particular weed species to your retailer or UPL NA representative.



110 and 120 Gallon Compack Containers

Equipment Requirements:

UP-STAGE 3CS is a microencapsulated herbicide and requires a diaphragm type pump in order to maintain product quality. DO NOT use gear or pistontype pumps. Bulk/Minibulk containers have been prefitted with a Scienco DD6 diaphragm type pump for recirculation and dispensing of product.

Dispensing Instructions:

When ready to dispense UP-STAGE 3CS from the Compack, the applicator must recirculate the product in the container, if the product has settled or separated, for approximately 5 minutes or until the product is thoroughly turned over. The Scienco DD6 pump is equipped with recirculation capability. This allows for quick and efficient mixing of product which may have separated or settled in storage. To recirculate, press down the bypass pushrod lever to the locked position (slid under the motor) and turn on the motor. The discharge ball valve at the end of the hose must be closed before turning on the motor. Once the product is thoroughly recirculated the applicator may then begin the process of dispensing UP-STAGE 3CS into the spray tank, loading or mixing system.

250 Gallon Bulkdrum III Containers

Equipment Requirements:

UP-STAGE 3CS is a microencapsulated herbicide and requires a diaphragm type pump in order to maintain product quality. DO NOT use gear or pistontype pumps. The following pumps are suitable for moving UP-STAGE 3CS from the 250 gallon Bulkdrum into spray tanks, mixing systems, or dedicated repackaging minibulk tanks*:

Tuthill Fill-Rite Chemtraveller portable transfer pump
Scienco Caddy-SS portable transfer pump
Scienco DD6 pump
Tuthill Fill-Rite Series 400 diaphragm pumps

Dispensing Instructions:

When ready to dispense UP-STAGE 3CS from the Bulkdrum, the dealer/ applicator must recirculate the product in the container, for at least 15 minutes. This can be done by hooking a portable pump such as listed above to the bottom bung, opening the valve and directing the outlet nozzle into the 6" top port (seal must be broken). Directing the nozzle stream into the corners will ensure more complete turning of the product volume. Once the product is thoroughly circulated, the dealer/applicator may then begin the process of dispensing UP-STAGE 3CS into the dedicated repackaging minibulk container(s)*, or spray tank, loading or mixing system. Rinse the empty Bulkdrum container and transfer the rinsate directly to the mix or spray tank.

* Any dealer wishing to repackage UP-STAGE 3CS must comply with all Federal, State and local laws pertaining to bulk herbicide handling and possess a signed repackaging agreement from UPL NA.


- DO NOT use gear or piston-type pumps

- DO NOT apply this product by air or through irrigation equipment.

- DO NOT apply UP-STAGE 3CS herbicide to non-field areas including fence rows, waterways, ditches, and roadsides.

- When moving spray equipment to noncontiguous sites, do not allow spray solution to spray or drip from tanks, hoses, fittings or spray nozzles and tips.

- DO NOT apply when weather conditions favor drift.

- Off-site movement of spray drift or vapors of UP-STAGE 3CS herbicide can cause foliar whitening or yellowing of some plants. Prior to making applications, read and strictly follow all precautions and instructions in the APPLICATION DIRECTIONS, MANDATORY SPRAY DRIFT and SPRAY DRIFT ADVISORIES sections.




- The microencapsulation of clomazone, the active ingredient in UP-STAGE 3CS, is intended to minimize movement away from the site of application. Avoid making applications when spray particles may be carried by air currents to areas where sensitive crops and plants are growing, or when temperature inversions exist. Leave an adequate buffer zone between the area to be treated and desirable plants. Foliar contact with spray drift or vapors may cause foliar whitening or yellowing of sensitive plants. Symptoms are generally temporary in nature, but may persist on some plant species.

Application restrictions must be taken as follows:

- Observe all buffer restrictions.

- Before application, determine air movement and direction.

Refer to crop use directions for additional requirements.

Under some conditions, temporary whitening or yellowing of leaves may occur on approved rotational crops where undesirable soil residues of UP-STAGE 3CS exist. Under abnormal conditions, carryover injury to rotational crops can occur. The following factors can contribute to increased risk of injury to rotational crops:

1) Over-application resulting from use of worn nozzles, excessive over-lapping of spray swaths, failing to shut off spray booms when turning (end row areas), or slowing or stopping sprayer.

2) Soil with pH less than or equal to 5.9.

3) Extreme dryness in the four months following application.

4) Choice of rotational crop hybrid.

Additional instructions to prevent rotational crop injury may be provided in the form of service bulletins for locations where risk of injury is significantly increased due to extremely dry conditions.

Refer to ROTATIONAL CROP INSTRUCTIONS and REPLANTING INSTRUCTIONS of specific crops for additional crop planting information.

DO NOT drain or flush equipment on or near desirable trees or other plants, or in areas where their roots may extend or in locations where the chemical may be washed or move into contact with their roots. DO NOT contaminate any body of water including irrigation water that may be used on other crops. Carefully follow sprayer clean-up instructions noted below to prevent spray tank residues from damaging other crops.

Thoroughly rinse sprayer equipment to remove residues of herbicide that might injure other subsequently sprayed crops. Follow the steps below for the thorough rinsing of spray equipment following applications of UP-STAGE 3CS herbicide or tank mixes of UP-STAGE 3CS with other labeled products.

1) Drain any remaining spray solution from tank, pump, hoses and boom and discard in an approved manner (see NOTE that follows).

2) Clean tank and fittings by:

- Thoroughly hosing down the inside walls of the spray tank with a quantity of water equal to 1/8 of the total tank capacity and operating the pump to circulate this solution through the sprayer system for 15 minutes.

- Washing down the outside surfaces of equipment.

- Removing nozzle tip and screen from end nozzle in each boom section and allowing several gallons of rinsate solution to flush completely through boom (collect rinsate while flushing).

3) Thoroughly drain remaining rinsate solution from tank, pump and hoses. Combine with boom flushing and dispose of all rinsates from this first rinsing in an approved manner (see NOTE that follows).

- When switching from water dilutions to applications utilizing crop oil or liquid fertilizer as a carrier, flush a small volume of crop oil or liquid fertilizer through the tank, pump, hoses, and boom prior to the next use. Dispose of crop oil or liquid fertilizer rinsate in an approved manner (see

NOTE for local, state and federal guidelines).

4) Remove the remaining nozzle tips, and screens and the line filter and wash in a pail of warm soapy water, thoroughly rinse and replace.

5) Hose down the inside walls of the spray tank a second time and circulate this solution using the same procedure as noted in #2 above.

6) If the next use of the sprayer will be for applying a pre-emergent or preplant incorporated pesticide on any crop for which UP-STAGE 3CS is registered, rinsate from this second rinsing may be utilized by diluting with the water for the next pesticide load;

If the next use of the sprayer will be a post-emergence applied pesticide on any crop, drain rinsate solution from this second rinsing. Retain rinsate solution for use only with a soil incorporated pesticide to be applied on a crop for which UP-STAGE 3CS is registered. Refill tank (after draining second rinsate solution) in accordance with post-emergence product label directions.

NOTE: Dispose of excess spray mixture and/or rinsate from first tank rinsing by application to cropland as described on this label. If excess spray mixture and/or rinsate from first rinsing cannot be disposed of according to label instructions, dispose of in compliance with local, state and federal guidelines. Contact your state pesticide or Environmental Control Agency or the Hazardous Waste representative at the nearest EPA regional office for guidance.

Care must be taken when mixing UP-STAGE 3CS herbicide. Avoid mixing in areas adjacent to desirable plants.

UP-STAGE 3CS Alone: Mix UP-STAGE 3CS with water or liquid fertilizer in the following manner: Fill the spray tank one-half to three-fourths full with water or liquid fertilizer, add the proper amount of UP-STAGE 3CS, then add the rest of the water or liquid fertilizer. Provide sufficient agitation during mixing and application to maintain a uniform spray mixture.

Tank Mixtures: Fill spray tank 1/4 to 1/3 full with water; with agitator operating add the specified amount of ingredients using the following order: dry formulations (e.g., wettable powders, dry flowables) first, liquid suspensions (e.g., flowables) next and finally liquids (e.g., EC’s). Mix thoroughly and fill tank one-half full continuing agitation. Add UP-STAGE 3CS herbicide to tank while maintaining agitation. Complete filling the sprayer tank with water. Where use of a surfactant is indicated, add as the last ingredient to the spray tank. Maintain agitation during filling, mixing and application. When using drift reducing agents, follow specific product label instructions for order of addition to spray tank. It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.

Fertilizer Spray Mixtures: Applications of UP-STAGE 3CS alone, or with indicated tank mixtures, in conjunction with fertilizer solutions may be used unless use directions specifically state otherwise. Test small quantities for compatibility by the following procedure before mixing tank full quantities.

1) Put 1 pint of fertilizer solution in a quart jar.

2) Add the appropriate amount of herbicide based on the table below. If more than one product is to be used, add each separately using the following sequence: dry formulations (e.g., wettable powders, dry flowables) first, liquid suspensions (e.g., flowables) next and finally liquids (e.g., EC’s).

3) Close jar and shake well.

4) Watch mixture for several seconds, again in 5 minutes and again after 30 minutes. If herbicide/fertilizer combination remains mixed or can be remixed readily (i.e., does not permanently separate, foam, gel or become lumpy), the mixture is compatible and can be mixed in full volumes and sprayed. If the mixture is compatible, prepare spray by adding fertilizer solution to the tank first, then follow directions noted below:

A) UP-STAGE 3CS Alone: Dilute with 2 parts of water and add slowly to spray tank of fertilizer with agitator running. Maintain agitation during application.

B) UP-STAGE 3CS plus Tank Mixtures: Dilute with two (2) parts of water, then add to the spray tank of fertilizer, while maintaining agitation, using the following order-slurry of dry formulations (wettable powders, dry flowables) first, diluted liquid formulations (EC’s, flowables) second. Continue agitation during application.

It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.


Ground Applications

Broadcast or Banded Applications: Apply UP-STAGE 3CS alone or in tank mix combinations by ground equipment using a finished spray volume of 10 to 40 gallons of water per acre. For UP-STAGE 3CS tank mixtures with wettable powder or dry flowable formulations, use nozzle screens and strainers no finer than 50-mesh.

UP-STAGE 3CS may be used as a pre-emergent soil surface applied treatment from 30 days before planting to just prior to crop emergence. If field conditions indicate the need for additional seedbed preparation, the use of equipment which will move the herbicide no deeper than 1 1/2 - 2" is acceptable.

Cultivation After Planting
If cultivation is necessary because of soil crusting, compaction, or weed emergence, soil treated with UP-STAGE 3CS may be shallow-cultivated (no deeper than 1 1/2 - 2") or rotary-hoed without reducing the weed control activity of UP-STAGE 3CS. Avoid deep cultivation which may bring untreated soil to the surface and result in poor weed control.

Limitations, Restrictions, and Exceptions


UP-STAGE 3CS herbicide may be utilized as a surface broadcast treatment prior to weed emergence, for the control of annual grass weeds in dry-seeded rice.

UP-STAGE 3CS may be applied as a surface broadcast application 14 days prior to planting or up to 7 days after planting, but prior to weed emergence, using ground equipment in a minimum of 10 to 40 gallons of water per acre at the rate of 11 - 34 fl oz product (2/3 - 2 1/8 pints product, 0.25 - 0.8 lb ai)/A depending upon the soil texture. Refer to table below for specific rates and weeds controlled. For heavy soils use the higher specified rate, otherwise less than desirable weed control may result.

For pre-emergent broadcast treatments, refer to the directions for broadcast applications in the APPLICATION INSTRUCTIONS section.

If initial planting of rice fails to produce a uniform stand, rice may be replanted in fields treated with UP-STAGE 3CS. When tank mixing with a labeled product, refer to the replant instructions for that product. When a tank mix is used, refer to the product’s label for any additional rotational crop instructions.

Partial weed control may result if levees are pulled after UP-STAGE 3CS has been applied. Additional use of labeled post-emergence herbicide applications may be required.

Both pre-emergent surface broadcast applications and early post-emergence applications (out to the five leaf stage) of UP-STAGE 3CS may be made during the same season to control the above weeds as long as the total yearly application does not exceed 34 fl oz (0.8 lb ai)/A. Refer to the table below for specific rates.

Application of UP-STAGE 3CS herbicide to fields which have been precision leveled with deep cuts may result in rice crop injury including stand loss. Consult with rice specialists for soil amending practices which can reduce potential for herbicide injury in precision leveled fields.

Rotate to crops as listed below. Refer to section headed Rotational Cropping Precautions.

Note: When using UP-STAGE 3CS with other registered herbicides always refer to rotational restrictions and directions on the other product’s label.

Cover crops may be planted anytime but stand reductions may occur in some areas.



- DO NOT use this treatment in water-seeded rice.

- DO NOT apply UP-STAGE 3CS on rice fields in which concurrent crayfish or catfish farming are included in the cultural practices.

- DO NOT use water containing UP-STAGE 3CS residues from rice cultivation to irrigate food or feed crops which are not registered for use with UP-STAGE 3CS.

- DO NOT apply more than 34 fl oz UP-STAGE 3CS (0.8 lb ai)/A per year or in a single application.

- DO NOT make more than two applications per year when using reduced application rates.

- DO NOT make more than one pre-emergent application.

- DO NOT make more than one post-emergent application after rice emergence up to five-leaf rice.

- DO NOT make a post-emergent application any sooner than 7 days following a pre-emergent application.

- DO NOT retreat fields with a second pre-emergent application of UP-STAGE 3CS.

- DO NOT replant treated fields with any crop at intervals that are inconsistent with the ROTATIONAL CROP INSTRUCTIONS on the UP-STAGE 3CS label.

- DO NOT graze or harvest for food or feed cover crops planted less than 9 months after UP-STAGE 3CS treatment.
