TURFGRASS - WARM SEASON GRASSES - BEARDED SPRANGLETOP, ETC.

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

TURFGRASS

Do not use Pennant MAGNUM on turfgrasses in New York State.

Apply Pennant MAGNUM before weeds emerge. Since soil moisture is necessary to activate Pennant MAGNUM, irrigate with 1/2 inch of water if rainfall does not occur within 7 days after treatment (See following Precautions).

Notes: (1) Split rate of applications can be made at rates not less than 1 pt./A. (2) Do not apply more than once every 6 weeks. (3) For commercial sod production, do not apply more than 4.2 pts./A per year to the same area used for sod production. (4) For other turf uses, do not apply more than 2.6 pts./A per year.

Precautions for all uses on turf: Delayed spring green-up, temporary slowing of growth and yellowing may occur following application. To avoid turf injury, (1) Application of a nitrogen-containing fertilizer at or soon after applying Pennant MAGNUM will minimize delay in spring green-up and any temporary yellowing; (2) use only on turfgrass not under stress from infestations of insects, nematodes, or diseases; (3) do not use on golf greens, tees, or aprons; (4) do not seed or overseed with desirable turfgrass 4 months before or after treatment, and (5) do not apply this product to newly seeded grasses until they have overwintered and have a well-developed rhizome system. (6) Before using Pennant MAGNUM in the tank mix with fluid fertilizer or other registered pesticides, determine the tolerance of the turf species by applying the combination to a limited area during a period of active growth. (7) In turfgrass areas which have heavy thatch, the weed control of Pennant MAGNUM may be reduced.

Restrictions: To avoid possible illegal residues, do not graze or feed turf clippings to animals.
