General Information

PRODUCT INFORMATION

Pennant Magnum Herbicide controls many annual grasses, certain annual broadleaf weeds, and yellow nutsedge. Pennant Magnum may be used on commercial and residential warm-season turfgrasses and other noncrop land, including, but not limited to the following: airports, roadsides, golf courses, sports fields, public recreational areas, ornamental gardens, cemeteries, other landscaped areas, etc. Pennant Magnum may also be used in and around container and field-grown ornamentals, nonbearing nursery stock, and on sod farms.

DO NOT USE IN GREENHOUSES OR OTHER ENCLOSED STRUCTURES.

Do not apply under conditions which favor runoff or wind erosion of soil containing this product to nontarget areas.

To prevent off-site movement due to runoff or wind erosion:

1. Avoid treating powdery dry or light sand soils when conditions are favorable for wind erosion. Under these conditions, the soil surface should first be settled by rainfall or irrigation.

2. Do not apply to impervious substrates such as paved or highly compacted surfaces.

3. Do not use tailwater from the first flood or furrow irrigation of treated fields to treat nontarget crops unless at least 1/2 inch of rainfall has occurred between application and the first irrigation.

NOTICE TO USER: Plant tolerances to Pennant Magnum Herbicide have been found to be acceptable in the specific genera and species listed on the label. Because of the large number of species and varieties of plants, it is impossible to test each for tolerance to Pennant Magnum. Neither the manufacturer nor the seller has determined whether or not Pennant Magnum can be used safely on plants not specified on the label. Therefore, the professional user should determine if Pennant Magnum can be used safely by testing the recommended rates on a particular group of similar unlabeled ornamental plants in a small area before widespread use or by checking with the local weed specialist for guidance. Likewise, if the professional user plans to apply Pennant Magnum for control of weed species not listed on the label, Pennant Magnum should be tested on a small-scale basis before widespread use or the local weed specialist contacted for guidance.

APPLICATION PROCEDURES

Ground Application: Apply Pennant Magnum alone or in tank mixtures by ground equipment in a minimum of 10 gals. of spray mixture per acre, unless otherwise specified.

Use sprayers that provide accurate and uniform application. For Pennant Magnum tank mixtures with wettable powder or dry flowable formulations, screens and strainers should be no finer than 50-mesh. Rinse sprayer thoroughly with clean water immediately after use.

Aerial Application (Sod Farms Only): Apply Pennant Magnum in water alone or in tank mixtures with AAtrex, Princep, or other herbicides registered for use on sod farms in a minimum total volume of 2 gals./A by aircraft. See Turfgrass section for listing of applicable warm-season grasses. Avoid application under conditions where uniform coverage cannot be obtained or where excessive spray drift may occur. In order to assure that spray will be controllable within the target area when used according to label directions, make applications at a maximum height of 10 ft., using low-drift nozzles at a maximum pressure of 40 psi, and restrict application to periods when wind speed does not exceed 10 mph. To assure that spray will not adversely affect adjacent sensitive nontarget plants, apply Pennant Magnum or Pennant Magnum mixtures at a minimum upwind distance of 400 ft. from sensitive plants.

Avoid application to humans or animals. Flagmen and loaders should avoid inhalation of spray mist and prolonged contact with skin.

Application

Apply 100-800 lbs. of the herbicide/fertilizer mixture per acre. For best results, apply the mixture uniformly to the soil with properly calibrated equipment immediately after blending. Uniform application of the herbicide/fertilizer mixture is essential to prevent possible crop injury. Nonuniform application may also result in unsatisfactory weed control. In areas where conventional tillage is practiced, a shallow incorporation of the mixture into the soil may improve weed control. On fine- or medium-textured soils in areas where soil incorporation is not planned, i.e., reduced tillage situations or in some conventional tillage situations, make applications approximately 30 days before planting to allow moisture to move the herbicide/fertilizer mixture into the soil. On coarse-textured soils, make applications approximately 14 days prior to planting.

Precaution: To avoid potential injury of ornamental plants, do not use the herbicide/fertilizer mixture on container-grown plants and where planting beds are being formed.

Limitations, Restrictions, and Exceptions

NURSERIES AND LANDSCAPE PLANTINGS

Calibrate applicator equipment before use according to the manufacturer’s directions.

Application

Apply Pennant MAGNUM in sufficient carrier to obtain thorough coverage. For liquid carriers, use a minimum of 10 gals./A. Apply before grass, broadleaf weeds, or yellow nutsedge emerge, or after existing weeds or nutsedge plants have been removed. A second application may be needed to provide longer weed control not to exceed a total of 4.2 pts./A (46 ml/1,000 sq. ft.) per year or crop cycle, whichever is less.

Use higher rates for a given soil texture on high organic matter soils and where yellow nutsedge and/or a heavy infestation of weeds is expected. Use the lower rates on soils with low organic matter content and where light infestations of weeds are expected. In peat and muck soils and soils highly enriched with organic matter (i.e., sawdust) and/or synthetic mixes, the activity of Pennant MAGNUM may be reduced.

If banded applications are used, refer to the General Information section of the label to calculate the amount of Pennant MAGNUM needed.

Precautions: (1) To avoid plant injury, do not apply Pennant MAGNUM to seedbeds, cutting beds, or unrooted cuttings before transplanting or to plants until the soil has firmly settled around roots. (2) When Pennant MAGNUM is applied broadcast over-the-top of plant foliage, follow with sufficient overhead irrigation to wash Pennant MAGNUM from the foliage to reduce the chance of injury.

Field- and Liner-Grown Plants and Plants in Landscape Plantings

Liner-Grown Plants - Plants transplanted normally in rows in a nursery or similar area for further growth before transplanting to final growing location (place of establishment).

Citrus (Citrus spp.), Crabapple, Apple (Malus spp.), Cherry (Prunus spp.), Pear (Pyrus spp.): Do not apply to trees or plants that will bear harvestable fruit within 12 months, or illegal residues may result.

Pennant MAGNUM may be applied in tank mixtures with Barricade, Factor, Goal, Princep, Ronstar, Roundup, or other compatible herbicides registered for use on ornamentals. Refer to the respective product labels for weeds controlled and for plants on which they are registered for use. When applying Pennant MAGNUM in tank mixtures, observe the more restrictive directions for use, precautions, and limitations on the label or the respective tank mix product label.

Common purslane, groundsel, hairy nightshade, sandbur, seedling johnsongrass, shattercane, volunteer sorghum: Control of these weeds can be erratic due partially to variable weather conditions.
