NONCROPLAND AREAS - GRASSES (4-6 PINTS / ACRE)

General Information

GENERAL INFORMATION

ARSENAL is an aqueous solution containing surfactant to be mixed in water and applied as a spray for control of most annual and perennial grasses and broadleaf weeds on noncropland areas.

ARSENAL may be applied either preemergence or postemergence to the weeds; however, postemergence application is the method of choice in most situations, particularly for control of perennials. For maximum activity, weeds should be growing vigorously at the time of postemergence application. The preemergence activity of ARSENAL will provide residual control of new germination of most weed species following a postemergence application.

ARSENAL is readily absorbed through leaves, stems, and roots and is translocated rapidly throughout the plant, with accumulation in the meristematic regions. Treated plants stop growing soon after spray application. Chlorosis appears first in the newest leaves, and necrosis spreads from this point. In perennials, the herbicide is translocated into, and kills, underground storage organs, thus preventing regrowth. Chlorosis and tissue necrosis may not be apparent in some plant species until two weeks after application. Complete kill of plants may not occur for several weeks.

APPLICATION EQUIPMENT AND TECHNIQUES
Arsenal Railroad herbicide may be applied with the following applications equipment:
Aerial: fixed wing and helicopter.
Boom: conventional boom mounted, manifold mounted, and off-center nozzles.
Low-volume hand-held spray equipment: backpack, knapsack and other pump-up type pressure sprayers and backpack mist blowers used to direct application to weed foliage.
High-volume spray equipment: high pressure handguns and vehicle mounted high-volume directed spray equipment.

AERIAL EQUIPMENT
Uniformly apply the recommended amount of Arsenal Railroad with properly calibrated aerial equipment in 5 to 30 gallons of water per acre. All precautions should be taken to minimize or eliminate spray drift. Aerial equipment designed to minimize spray drift, such as a helicopter equipped with a MICROFOIL boom, THRU-VALVE boom or raindrop nozzles, must be used. Applications should not be made under gusty conditions or when wind velocity exceeds 5 mph. Except when applying with a MICROFOIL boom, a drift control agent may be added at the recommended label rate. A foam reducing agent may be added at the recommended label rate, if needed.

IMPORTANT: DO NOT make applications by fixed wing aircraft unless appropriate buffer zones can be maintained to insure that drift does not occur off the target area.
Thoroughly clean application equipment, including landing gear, immediately after use. Prolonged exposure of this product to uncoated steel (except stainless steel) surfaces may result in corrosion and failure of the exposed part.

BOOM EQUIPMENT
Mix the recommended amount of Arsenal Railroad in 10 to 60 gallons of water per acre in the spray tank with the agitator running. A foam reducing agent may be added at the recommended label rate, if needed. If desired, a spray pattern indicator may be added at the recommended label rate. Check for even distribution in spray pattern. IMPORTANT: To minimize drift, select proper nozzles; to avoid spraying a fine mist, DO NOT exceed spray pressures of 50 psi, and DO NOT spray under gusty or windy conditions.

Clean application equipment after using this product by thoroughly flushing with water.

LOW-VOLUME HAND-HELD SPRAY EQUIPMENT
Thoroughly mix a 1/2 to 1 percent solution of Arsenal Railroad herbicide in water. To determine the proper percent solution of Arsenal Railroad to use, see the WEEDS CONTROLLED section of this label and the PERCENT SOLUTION RATE GUIDE below. The table calculations below are based on an approximate delivery volume of 50 to 75 gallons per acre.
PERCENT SOLUTION RATE GUIDE
ARSENAL RATE PER ACRE: 2-3 pints TO MIX: 1/2%
ARSENAL RATE PER ACRE: 3-4 pints TO MIX: 3/4%
ARSENAL RATE PER ACRE: 4-6 pints TO MIX: 1%

For best results, uniformly cover the foliage of the vegetation to be controlled with the spray solution.
DO NOT over apply and cause runoff from the treated foliage.
To mix the spray solution, add the volume of Arsenal Railroad indicated in the table below to the desired amount of water.

AMOUNT OF Arsenal Railroad TO USE (fluid volume)
SOLUTION VOLUME
1 gallon; For 1/2%: 2/3 oz; For 3/4%: 1 oz; For 1%: 1-1/3 oz
5 gallons; For 1/2%: 3-1/3 oz; For 3/4%: 5 oz; For 1%:6-1/2 oz
10 gallons; For 1/2%: 6-2/3 oz; For 3/4%: 10 oz; For 1%:13 oz
25 gallons; For 1/2%: 1 pint; For 3/4%: 1-1/2 pints; For 1%:2 pints

2 tablespoons = 1 fluid ounce

IMPORTANT: DO NOT exceed recommended dosage rate per acre. DO NOT side-trim desirable vegetation with this product. Clean application equipment after using this product by thoroughly flushing with water.

HIGH-VOLUME SPRAY EQUIPMENT
Arsenal Railroad may be applied using high-volume spray equipment. For best results, apply Arsenal Railroad using the least amount of water practical to obtain uniform coverage of the vegetation foliage. Using excessive spray volumes which cause runoff from the plant foliage may results in reduced performance.
When using spray volumes greater than 60 gallons per acre, additional nonionic surfactant such as Ortho* X-77 must then be added at the rate of 1 quart per 100 gallons of spray solution to provide optimum wetting and/or contact activity. A foam reducing agent may be added at the recommended label rate, if needed. If desired, a spray pattern indicator may be added at the recommended label rate.
To mix the spray solution, determine the proper Arsenal Railroad pints per acre rate from the WEEDS CONTROLLED section of this label.

WEEDS CONTROLLED

ARSENAL will provide postemergence control with residual control of the following target vegetation species. Residual control refers to control of newly germinating seedlings in both annuals and perennials. In general, annual weeds may be controlled by preemergence or postemergence applications of ARSENAL; whereas, for established biennials and perennials, postemergence applications of ARSENAL are recommended.

Limitations, Restrictions, and Exceptions

GRASSES

- The higher rates should be used where heavy or well established infestations occur.
