ALFALFA (NON-DORMANT, NON-WINTER HARDY VARIETIES)
SOIL TEXTURE: As used on the label, “Coarse soils” are loamy sand or sandy loam soils. “Medium soils” are loam, silt loam, silt, sandy clay, or sandy clay loam. “Fine soils” are silty clay, silty clay loam, clay, or clay loam. Silty clay loam soils are transitional soils and may be classified as medium textured soils in some regions of the U.S.
GENERAL PRECAUTIONS AND RESTRICTIONS
Do not allow sprays to drift on to adjacent desirable plants.
Apply this product only as specified on the label.
Do not use on other crops grown for food or forage.Observe all cautions and limitations on labeling of all products used in mixtures.
For all uses: Low-pressure and high-volume hand-wand equipment is prohibited.
APPLICATION OF METRIBUZIN DF WITH HERBICIDE SPRAY EQUIPMENT
Use a standard low pressure (20 to 40 psi.) herbicide boom sprayer equipped with suitable nozzles and screens no finer than 50-mesh in nozzle and in-line strainers. Agitate thoroughly before and during application with bypass agitation.
GROUND APPLICATION: Apply the proper rate of Metribuzin DF in a minimum of 10 to 40 gallons of spray mixture per acre broadcast.
Banded Application: Use proportionally less Metribuzin DF per acre in a band versus a broadcast application. For band application use 1/4 to 1 gallon of spray mix per inch of band width regardless of row spacing.
EXAMPLES: (1) To treat a 15-inch band on rows 30 inches apart, use one-half of the broadcast rate of Metribuzin. (2) To treat a 14-inch band on rows 42 inches apart, use one-third of the broadcast rate of Metribuzin.
AERIAL APPLICATION: Where permitted, apply specified rate in a minimum of 2 to 10 gallons of spray mixture per acre. Do not apply aerially when wind speed is greater than 10 mph.
NOTE: Do not apply aerially when Metribuzin is tank-mixed with Lasso.
For All Applications of Metribuzin DF: Sprayer must be accurately calibrated before applying Metribuzin DF. Check sprayer during application to be sure it is working properly and delivering a uniform spray pattern. As the volume of spray mixture decreases per acre, the importance of accurate calibration and uniform application increases. Avoid over application, misapplication, and boom and spray swath overlapping that will increase spray dosage. (Crop injury may occur as a result). Avoid spray skips and gaps which allow weeds to grow in untreated soil. Do not apply when weather conditions favor spray drift and/or when sensitive or cool season crops, such as cole crops, onions, peas, or strawberries are present in adjacent fields or in areas where wheat is growing in coarse textured soils.
COMMERCIAL IMPREGNATION AND APPLICATION OF METRIBUZIN DF ON DRY BULK FERTILIZER
Dry bulk fertilizer may be impregnated or coated with Metribuzin DF for application to established alfalfa and to soybeans. All recommendations, cautions, and special precautions on the label must be followed along with state regulations relating to dry bulk fertilizer blending, impregnating and labeling.
APPLICATION: Uniform application is essential for satisfactory weed control. Accurate calibration of fertilizer application equipment is essential for uniform distribution to the soil surface. The recommended method of application is to apply 1/2 the recommended rate and overlap 50 percent or to double apply by splitting the middles to obtain the best distribution pattern.
If fertilizer materials are excessively dusty, use diesel oil or other suitable additive to reduce dust prior to impregnation as dusty fertilizer will result in poor distribution during application. Crop injury and/or poor weed control may occur where the impregnated fertilizer is not uniformly applied.
INCORPORATION AND COMBINATION USES: When Metribuzin DF is to be used in combination with another herbicide, follow directions on the label for combinations, rates, crops, incorporation, and special precautions.
Non-Dormant, Non-Winter Hardy Varieties
Metribuzin DF is recommended as a broadcast surface application to established crops of non-dormant alfalfa varieties for preemergence and postemergence control of certain winter annual weeds following either a fall or winter sheep grazing/green-chop harvest.
Apply specified dosage by aerial or ground spray equipment in 7 to 40 gallons of water per acre. Treat established alfalfa stubble after fall or winter sheep grazing or green-chop harvest and prior to the time regrowth is 2\" tall. Alfalfa foliage present at time of application can exhibit yellowing. Injury may occur to alfalfa in areas of high salt concentration where the crop is stunted and/or has a poorly developed root system, or if alfalfa is under stressed growing conditions such as diseases, insect infestations, or drought. For most effective post-emergence weed control, treatment should be made before weeds are 2\" tall or before leaf rosettes are 2\" wide. For maximum control, rainfall (1/4\" or more) or irrigation is necessary within 30 days of treatment, however, do not flood irrigate within 2 days after treatment. Use 1/2 lb Metribuzin on sand soil when only mustard, goosefoot, lambsquarters, or canary grass are the weeds to be controlled. Do not apply earlier than 6 months after seeding. Do not graze or harvest within 28 days after application.
SPECIAL PRECAUTIONS: Maintain continuous mechanical agitation in the spray tank to insure a uniform spray mixture.
Do not apply with aerial spray equipment when wind speed is greater than 10 mph. Do not apply when weather conditions favor spray drift and/or when sensitive cool season crops, such as cole crops, onions, peas or strawberries, are present in adjacent fields.
Applications should not be made when weather conditions favor drift especially in areas where wheat is growing on coarse textured soils in adjacent fields, or injury may occur.
