PRODUCT INFORMATION
HER11 herbicide is a dispersible granule that is used for selective postemergence weed control in wheat (including durum), barley, oats, triticale and fallow. The best control is obtained when HER11 is applied to young, actively growing weeds. The use rate will depend on weed spectrum and size of weed at time of application. The degree and duration of control may depend on the following:
• weed spectrum and infestation intensity
• weed size at application
• environmental conditions at and following treatment HER11 herbicide is a dispersible granule to be mixed in water or other recommended carrier and applied as a uniform broadcast spray. It is noncorrosive, nonflammable, nonvolatile and does not freeze.

RESTRICTIONS
Injury to or loss of adjacent sensitive crops, desirable trees or vegetation may result from failure to observe the following:
• Do not apply, drain or flush equipment on or near desirable trees or other plants or on areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots.
• Do not use on lawns, walks, driveways, tennis courts, or similar areas. Prevent drift of spray to desirable plants. Do not apply to wheat, barley, oats, and triticale underseeded with another crop.
Dry, dusty field conditions may result in reduced control in wheel track areas. Also observe the following: Do not harvest wheat or barley sooner than 45 days after the last application of HER11.
When using HER11 in tank mixes or sequential applications with other products containing thifensulfuron-methyl and/or tribenuron-methyl, do not exceed the following limits.

PRECAUTIONS
Injury to or loss of adjacent sensitive crops, desirable trees or vegetation may result from failure to observe the following:
• Take all necessary precautions to avoid all direct or indirect contact (such as spray drift) with non-target plants or areas.
• Carefully observe all sprayer cleanup instructions both prior to and after using this product, as spray tank residue may damage crops other than wheat, barley, oats, and triticale. Wheat, barley, oats, and triticale may differ in their response to various herbicides. FMC recommends that you first consult your state experiment station, university, or extension agent as to sensitivity to any herbicide. If no information is available, limit the initial use of HER11 to a small area.
HER11 should not be applied to wheat , barley, oats, and triticale that is stressed by severe weather conditions, drought (including low levels of subsoil moisture), low fertility, water-saturated soil, disease, or insect damage, as crop injury may result. Risk of injury is greatest when crop is in the 2 to 5-leaf stage. Severe winter stress, drought, disease, or insect damage following application also may result in crop injury.
Under certain conditions, such as heavy rainfall, prolonged cold weather (daily high temperature less than 50o F), or wide fluctuations in day/night temperatures prior to or soon after HER11 application, temporary discoloration and/or crop injury may occur. To reduce the potential of crop injury, tank mix HER11 with 2,4-D (ester formulations perform best–see “Tank Mixtures” section of this label) and apply after the crop is in the tillering stage of growth.

APPLICATION INFORMATION
USE RATE
Apply HER11 at a rate of 0.25 to 0.67 oz per acre. When applying 0.25 to 0.4 oz per acre, HER11 must be used in a tank-mix combination with other registered herbicides.

Wheat (including Durum), Barley and Triticale
Apply 0.25 to 0.67 oz HER11 per acre to wheat (including durum), barley or triticale. The total amount of HER11 cannot exceed 0.67 oz per acre per crop season.

Oats (Spring and Winter)
Apply 0.25 oz HER11 per acre for control of light populations of the weeds listed in Weeds Controlled table. In oats, HER11 must be used in a tank-mix combination with other registered herbicides such as HARMONY® SG. Do not make more than one application (or more than 0.1 ounces of active ingredient tribenuron-methyl) of HER11 per acre per crop season on oats.

Fallow
Apply 0.25 to 0.67 oz HER11 per acre to fallow. The total amount of HER11 cannot exceed 0.67 oz per acre per crop season. HER11 should be applied in combination with other suitable registered fallow herbicides such as glyphosate plus 2,4-D (ester formulations work best) or glyphosate plus dicamba.
When HER11 is applied at a rate of 0.25 to 0.4 oz per acre, HER11 must be used in a tank-mix combination with other registered fallow herbicides.

Pre-plant Burndown
Apply 0.25 to 0.67 oz HER11 per acre as a burndown treatment prior to, or shortly after planting (prior to emergence). The total amount of HER11 cannot exceed 0.67 oz per acre per crop season.

Post Harvest
Apply HER11 at 0.25 to 0.67 ounce per acre to crop stubble after harvest. Use the 0.67 ounce per acre rate when weed
infestation is heavy and predominantly consists of those weeds listed under the “WEEDS PARTIALLY CONTROLLED” section of this label or when application timing and environmental conditions are marginal. (See the “APPLICATION TIMING” section of this label for restriction on planting intervals). HER11 should be applied in combination with other suitable registered burndown herbicides (See the “TANK MIXTURES” section of this label for additional information). Sequential treatments of HER11 may also be made provided the total amount of HER11 applied during one fallow/pre plant cropland season does not exceed 0.67 ounce per acre.

APPLICATION TIMING
Since HER11 has very little or no soil activity, it controls only those weeds that have germinated; therefore, apply HER11 when all or most of the weeds have germinated. Annual broadleaf weeds should be past the cotyledon stage, actively growing, and less than 4" tall or wide. Rainfall immediately after treatment can wash HER11 off of weed foliage, resulting in reduced weed control. Several hours of dry weather are needed to allow HER11 to be sufficiently absorbed by weed foliage.

Wheat (Including Durum), Barley, Winter Oats and Triticale
Make applications after the crop is in the 2-leaf stage, but before the flag leaf is visible.

Spring Oats
Make applications after the crop is in the 3 leaf stage, but before jointing. Do not use on "Ogle", "Porter" or "Premier" varieties as crop injury can occur.

Fallow
HER11 may be used as a fallow treatment, in the spring, summer or fall when the majority of weeds have emerged and are actively growing.

Pre-plant Burndown
Apply HER11 as a burndown treatment to wheat (including durum) and barley to control emerged weeds prior to, or shortly after planting (prior to emergence). Make applications when the majority of weeds have emerged and are actively growing. HER11 can be used as a burndown treatment prior to planting other crops. See "CROP ROTATION" for the time interval required before planting.

Post Harvest
HER11 may be used as a burndown treatment to crop stubble when the majority of weeds have emerged and are actively growing. See the “CROP ROTATION” section of this label for additional information.
