BURNDOWN WEED CONTROL - FIELD CORN - PREPLANT (0-30 DAYS)
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.
BURNDOWN WEED CONTROL - Field Corn and Soybeans
Metribuzin DF can be used as part of a herbicide program for burndown of existing vegetation prior to crop emergence in conservation tillage systems. Metribuzin may be tank-mixed with 2,4-D low volatile ester (LVE), Gramoxone Extra, or Roundup / Roundup Ultra /Touchdown for control of emerged weeds prior to field corn or soybean emergence. Metribuzin tank-mixes with 2,4-DB, Fusion, Poast Plus or Select may also be used in soybeans for control of emerged weeds prior to crop emergence. Metribuzin DF burndown tank mixes can be applied before planting or prior to crop emergence in the following areas:
Illinois, Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota, Missouri, Nebraska, Ohio, South Dakota, and Wisconsin.
All areas for all products except Fusion tank-mixes - see Fusion section of the label for recommended states.
Application: Metribuzin DF may be applied up to 30 days prior to planting or pre-emergence. Apply only by ground equipment when Metribuzin DF is used for burndown of existing vegetation in conservation tillage systems. Metribuzin DF and tank-mix partner burndown rates are listed in the following three tables.
Special Precautions. Do not apply these treatments after crop emergence. Observe all precautions and limitations on the labeling of all products used in tank-mixtures. Refer to the General Information section of the label for additional information, precautions, and limitations.
1. Do not apply on coarse textured soils with less than 1.5% organic matter.
2. Do not apply more than 4 oz of Metribuzin DF per acre on soils with less than 2% organic matter.
3. Do not apply on soils having pH 7.0 or greater.
4. Do not apply more than 5-1/3 ounces Metribuzin DF (0.25 pound active ingredient) per acre per growing season.
5. Corn seed should be planted a minimum of 1-1/2 inches deep.
6. Metribuzin DF may only be used in hybrid seed corn production fields if both inbred parents are known to be tolerant to Metribuzin DF.
1. Apply only 2,4-D low volatile ester formulations which are registered and recommended for preplant or burndown use in soybeans.
2. Do not apply tank-mixtures containing 2,4-D LVE if wind is blowing toward desired susceptible plants (i.e. cotton, tobacco, tomato, etc.) or when wind speeds exceed 6 miles per hour.
Feeding restrictions. Corn treated with Metribuzin DF may be harvested for silage or grain 60 days after treatment. Soybean vines or hay treated with Metribuzin DF may be grazed or fed to livestock 40 days after application. Do not feed hay, forage, fodder or graze 2,4-D, Select, or Fusion treated vegetation. Follow the most restrictive preharvest interval of all products used in a tank-mixture.
