General Information



- The microencapsulation of clomazone, the active ingredient in Command 3ME, 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. Coarse sprays are less likely to drift out of the target area than fine sprays.

- 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 precautions must be taken as follows:

- Do not apply aerially or through irrigation equipment.

- Observe all buffer restrictions.

- Do not apply Command 3ME within 1,200 feet of the following areas: Towns and Housing Developments, Commercial Fruit/Nut or Vegetable Production, Commercial Greenhouses or Nurseries.

Except for peppers, pumpkins, succulent peas, sweet corn, sweet potato, and winter squash.

- Before application, determine air movement and direction.

- Do not apply in winds above 10 miles per hour.

- Do not apply Command 3ME 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.

Refer to individual crop use directions for additional requirements.


Care must be taken when mixing Command 3ME herbicide. Avoid mixing in areas adjacent to desirable plants.

Command 3ME Alone: Mix Command 3ME 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 Command 3ME, then add the rest of the water or liquid fertilizer. Provide sufficient agitation during mixing and application to maintain a uniform spray mixture.


Ground Applications

Broadcast or Banded Applications: Apply Command 3ME alone or in tank mix combinations by ground equipment using a finished spray volume of 10 to 40 gallons of water per acre. Use nozzles suitable for broadcast boom or banded application of herbicides. Coarse sprays are less likely to drift out of the target area than fine sprays. See “GENERAL APPLICATION PRECAUTIONS” and “SPRAY DRIFT PRECAUTIONS sections for specific recommendations to reduce spray drift. For Command 3ME tank mixtures with wettable powder or dry flowable formulations, nozzle screens and strainers should be no finer than 50- mesh.

Command 3 ME may be used as a preemergent 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 11/2 - 2” is acceptable.

Cultivation After Planting

If cultivation is necessary because of soil crusting, compaction, or weed emergence, soil treated with Command 3ME may be shallow-cultivated (no deeper than 11/ 2 - 2”) or rotary-hoed without reducing the weed control activity of Command 3ME. Avoid deep cultivation which may bring untreated soil to the surface and result in poor weed control.

Limitations, Restrictions, and Exceptions



Command 3ME herbicide may be utilized as a surface broadast treatment prior to weed emergence, for the control of annual grass weeds in dry-seeded rice.


Command 3ME 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. For heavy soils use the higher recommended rate, otherwise less than desirable weed control mayresult.

For preemergent broadcast treatments, refer to the directions for broadcast applications in the GENERAL APPLICATION INSTRUCTIONS section.


Command 3ME may be applied after planting as an early postemergence treatment to rice at the one to two leaf stage to provide preemergence and residual control of grass weeds. For control of existing grass present at the time of application include a postemergence herbicide registered for the control of grass species in rice. Consult postemergence herbicide label for specific directions regarding use rates and stage of weeds and crop.


If initial planting of rice fails to produce a uniform stand, rice may be replanted in fields treated with Command 3ME. Do not retreat fields with a second application of Command 3ME. When tank mixing with a labeled product, refer to the replant instructions for that product. Do not replant treated fields with any crop at intervals that are inconsistent with the ROTATIONAL CROP GUIDELINES on the Command 3ME label. When a tank mix is used, refer to the product’s label for any additional rotational crop guidelines.

Partial weed control may result if levees are pulled after Command 3ME has been applied. Additional use of labeled post-emerge herbicide applications may be required.


Application of Command 3ME 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.


Do not use this treatment in water-seeded rice.

Do not use Command 3ME for weed control in rice planted in sand, loamy sand or sandy loam soils.

Do not apply Command 3ME on rice fields in which concurrent crayfish or catfish farming are included in the cultural practices.

Do not use water containing Command 3ME residues from rice cultivation to irrigate food or feed crops which are not registered for use with Command 3ME.
