Soluble Granule
For Use on Cereals, Fallow and as a Pre-plant or Post-harvest Burndown Herbicide

PRODUCT INFORMATION
DPX-SBN49 is a water soluble granule that is used for selective postemergence weed control in wheat (including durum), barley, triticale, oats and for post-harvest burndown, fallow, and pre-plant burndown weed control. The best control is obtained when DPX-SBN49 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 weed spectrum and infestation intensity, weed size at application, and environmental conditions at and following treatment. DPX-SBN49 is noncorrosive, nonflammable, nonvolatile, and does not freeze. DPX-SBN49 should be mixed in water and applied as a uniform broadcast spray.

BIOLOGICAL ACTIVITY AND ENVIRONMENTAL CONDITIONS
DPX-SBN49 is absorbed through the foliage of broadleaf weeds, rapidly inhibiting their growth. Leaves of susceptible plants appear chlorotic from 1 to 3 weeks after application and the growing point subsequently dies. DPX-SBN49 provides the best control in vigorously growing crops that shade competitive weeds. Weed control in areas of thin crop stand or seeding skips may not be as satisfactory. However, a crop canopy that is too dense at application can intercept spray and reduce weed control.
DPX-SBN49 may injure crops that are stressed from adverse environmental conditions (such as extreme temperatures or moisture), abnormal soil conditions, or cultural practices. In addition, different varieties of the crop may have differing levels of sensitivity to treatment with DPX-SBN49 under otherwise normal conditions. Treatment of sensitive crop varieties may injure crops. To reduce the potential of crop injury to cereals, tank mix DPX-SBN49 with 2,4-D (ester formulations perform best–see the Tank Mixtures section of this label) and apply after the crop is in the tillering stage of growth.

AGRICULTURAL USE REQUIREMENTS
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR part 170. This Standard contains requirements for the protection of agricultural workers on farms, forests, nurseries, and greenhouses, and handlers of agricultural pesticides. It contains requirements for training, decontamination, notification, and emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on this label about personal protective equipment (PPE) and restricted-entry interval. The requirements in this box only apply to uses of this product that are covered by the Worker Protection Standard. Do not enter or allow worker entry into treated areas during the restricted entry interval (REI) of 12 hours. PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with
anything that has been treated, such as plants, soil, or water, is: Coveralls. In warm, moist conditions, the expression of herbicide symptoms is accelerated in weeds; in cold, dry conditions, expression of herbicide symptoms is delayed. In addition, weeds hardened-off by drought stress are less susceptible to DPX-SBN49. DPX-SBN49 is rainfast in 4 hours.

IMPORTANT USE RESTRICTIONS
Do not apply to wheat, barley, oats or triticale underseeded with another crop.
Do not apply this product through any type of irrigation system.
Injury to or loss of 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

IMPORTANT USE PRECAUTIONS
Injury to or loss of adjacent sensitive crops and 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 or barley.
Varieties of wheat (including durum), 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 crop sensitivity to any herbicide. If no information is available, limit the initial use to a small area.
Under certain conditions such as heavy rainfall, prolonged cold weather, or wide fluctuations in day/night temperatures prior to or soon after DPX-SBN49 application, temporary discoloration and/or crop injury may occur. To reduce the potential of crop injury, tank mix DPX-SBN49 with 2,4-D (ester formulations perform best - see the "TANK MIXTURES" section of this label) and apply after the crop is in the tillering stage of growth.
DPX-SBN49 should not be applied to wheat, barley, oats or triticale that is stressed by severe weather conditions, drought, 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
