GENERAL INFORMATION
GLEAN HERBICIDE DRY FLOWABLE application is recommended for selective control or suppression of certain broadleaf weeds as a spring postemergence treatment in wheat (spring, winter, or durum), barley or oats.
It is noncorrosive, nonflammable, nonvolatile and does not freeze. Wheat, barley, or oats may be grazed by or fed to livestock anytime after treatment.
Rainfall, soil temperature, and soil pH are important factors affecting GLEAN HERBICIDE DRY FLOWABLE breakdown in soil. GLEAN HERBICIDE DRY FLOWABLE breakdown is more rapid under conditions of low soil pH, high soil temperature, and high soil moisture. The breakdown process is slower under conditions of high soil pH, low soil temperature and low soil moisture.
GLEAN HERBICIDE DRY FLOWABLE should not be used on Agricultural land where soil pH is higher than 7.5 as extended soil residual activity may adversely affect crop rotation options beyond usual intervals.

IMPORTANT:
UNLESS OTHERWISE SPECIFIED IN THE "MINIMUM RECROPPING INTERVAL AND CROP ROTATION GUIDELINES" SECTION OF THIS LABEL, Agricultural land previously treated with GLEAN HERBICIDE DRY FLOWABLE cannot be rotated to crops other than wheat, oats, or barley until a FIELD BIOASSAY confirms that residues of "GLEAN Herbicide Dry Flowable" are not present. A FIELD BIOASSAY involves growing a test strip of the crop(s) intended for production the following year in fields previously treated with GLEAN HERBICIDE DRY FLOWABLE. Crop response will indicate whether or not to rotate to the crop(s) used in the test strip. See "Field Bioassay" section of label. Failure to follow these instructions could result in injury to subsequent crops.
GLEAN HERBICIDE DRY FLOWABLE controls susceptible annual weeds by both foliar and root uptake.
Best control of emerged annual weeds is obtained when weeds are actively growing, and when GLEAN HERBICIDE DRY FLOWABLE is applied to small weeds (less than 10 cm tall). Warm, moist growing conditions promote active weed growth and enhance the activity of GLEAN HERBICIDE DRY FLOWABLE; weeds stressed by moisture or temperature extremes may be less susceptible and incomplete weed kill may result. Residual control of weeds germinating after spray application is achieved when GLEAN HERBICIDE DRY FLOWABLE is carried into the seedling root zone by rainfall. For best results, sufficient rainfall to move GLEAN HERBICIDE DRY FLOWABLE 5 to 7 cm deep into the soil is required after application, before weeds develop an established root system and grow beyond the seedling stage.
GLEAN HERBICIDE DRY FLOWABLE rapidly inhibits growth of susceptible weeds. However, typical symptoms (discoloration) of dying weeds may not be noticeable for 1 to 3 weeks after application depending on growing conditions and weed susceptibility. Degree of control, and duration of effect depend on the rate used, weed sensitivity and weed size, growing conditions at and following treatment, precipitation, soil organic matter and pH.

AGRICULTURAL DIRECTIONS FOR USE
SURFACTANT
GLEAN HERBICIDE DRY FLOWABLE must be applied with a recommended surfactant (see Postemergence Applications in Crop) when used alone, or when tank mixed with 2,4-D or MCPA. Surfactant isnot required when tank mixing with Avenge 200-C, Hoegrass 284.
For mixing instructions see Spray Preparation section.
