General Information


WILDCARD XTRA is formulated as an emulsifiable concentrate containing the equivalent of 2 lbs. per gallon of bromoxynil and 2 pounds per gallon of MCPA.

WILDCARD XTRA is a selective postemergence herbicide for control of important broadleaf weeds infesting small grains (wheat, barley, oats, rye), conservation reserve program areas, and grass grown for seed. Optimum weed control is obtained when WILDCARD XTRA is applied to actively-growing weed seedlings. WILDCARD XTRA is primarily a contact herbicide, therefore thorough coverage of the weed seedlings is essential for optimum control.

WILDCARD XTRA has little residual activity. Therefore subsequent flushes of weeds will not be controlled by the initial treatment.

Generally crops that form a good canopy will help shade subsequent weed flushes. However, certain crops or short-straw varieties, for example Yaccora Rojo wheat, may not develop the crop canopy fast enough to shade the subsequent flushes of weeds.

Occasional transitory leaf burn may occur. The temporary leaf burn is similar to that seen with liquid fertilizer. Because the activity of WILDCARD XTRA is mainly contact, recovery of the crop is generally rapid with no lasting effect. Frequency and amount of leaf burn may be greater when crops are stressed by abrasive winds, cool to cold evening temperatures or mechanical injury, such as that caused by hail, sleet or insect feeding. To reduce the potential for temporary leaf burn, applications should be made to dry foliage in the recommended spray volumes per acre when weather conditions are not extreme.


WILDCARD XTRA can be applied to registered use areas by ground, aerial and sprinkler irrigation equipment.


Use a standard herbicide boom sprayer that provides uniform and accurate application. Sprayer should be equipped with screens no finer than 50 mesh in the nozzle tips and in-line strainers.

Select a spray volume and delivery system that will ensure thorough and uniform spray coverage. For optimum spray distribution and thorough coverage use of flat-fan nozzles (maximum tip size 8008) with a spray pressure of 40-60 psi are recommended. Other nozzle types and lower spray pressures that produce coarse spray droplets may not provide adequate coverage of the weeds to ensure optimum control. Raindrop nozzles and flood nozzles are not recommended as weed control with WILDCARD XTRA may be reduced.

In general, a spray volume of 10 to 20 gallons per acre (GPA) is recommended for optimum spray coverage. A minimum of 5 GPA with a minimum spray pressure of 50 psi and a maximum ground speed of 10 mph may be used with higher speed, low-volume ground application if ground terrain, crop and weed density allow effective spray distribution. When using higher speed equipment, a maximum ground speed of 10 mph is suggested if field conditions cause excessive boom movement during application which results in poor spray coverage. Ground applications made when dry, dusty field conditions exist may provide reduced weed control in wheel track areas. Applications using less than 10 gallons per acre may result in reduced weed control.

When weed infestations are heavy, use of higher spray volumes and spray pressure will be helpful in obtaining uniform weed coverage. When corn or grain sorghum are large enough to interfere with the spray pattern, drop nozzles should be used to obtain uniform weed coverage. If you are unsure of the infestation level or size of crop, consult your local extension service.

Do not apply when winds are gusty or when other conditions favor poor spray coverage and/or off target spray movement.


Use orifice discs, cores and nozzle types and arrangements that will provide for optimum spray distribution and maximum coverage. In general a minimum spray volume of 5 GPA and a maximum pressure of 40 psi are recommended. A minimum spray volume of 3 gallons per acre may be used if crop canopy and weed density allow adequate spray coverage. Aerial applications using less than 5 gallons of spray volume per acre may result in reduced weed control.

Do not apply during inversion conditions, when winds are gusty or when other conditions favor poor spray coverage and/or off target spray movement. Off target spray movement can be minimized by increasing the spray volume per acre and not applying when winds exceed 10 mph.


WILDCARD XTRA Herbicide can be applied through sprinkler irrigation systems to small grains and grasses grown for seed.

Apply WILDCARD XTRA Herbicide through sprinkler systems including center-pivot, lateral-move, side (wheel) roll, solid-set or hand-move irrigation systems only. If hand-moved pipe is used for chemigation, the pipe must not be handled in any way until 24 hours after chemigation has been completed and residues have been flushed from the system. When applying by chemigation, no person may enter the application site unless in an enclosed vehicle. Do not apply this product through any other type of irrigation system.


Postemergence application of WILDCARD XTRA Herbicide will control the following weeds when sprayed in the seedling stage.

Maximum weed stage of growth is listed under WILDCARD XTRA RECOMMENDATIONS of the label.

Limitations, Restrictions, and Exceptions


Spring seeded wheat, barley, oats and rye in Idaho, Oregon, Washington, Colorado, Wyoming and Montana.

Apply to wheat, barley, oats and rye from the 3 leaf stage but before the crop reaches the boot stage.

Apply to kochia that is 2-4 inches height.

Restrictions and Precautions: Wheat, Barley, Oats and Rye

- Do not graze treated field within 45 days after application.

- Do not apply when crops are under moisture stress.

- Do not apply when crop canopy covers the weeds as poor control will result.

- Reduced weed control may occur when weeds are stressed from lack of moisture or cold temperatures.

- Refer to labels of products used in tank-mixture for additional restrictions and precautions.

Restricted Entry Interval
