Product Overview

Celero Herbicide is an excellent selective water dispersible granule that actively destroys nutsedges and sedges in sod farms, office complexes, and golf courses. Also, perfect to use in commercial and residential turfgrass. It is highly effective to use on both cool and warm season turfs, making it an outstanding resistance management tool. Provides post-emergence control of both purple and yellow nutsedges, annual and cylindric sedge, green kyllinga, and various broadleaf weeds. This powerful herbicide contains an active ingredient that has superior sedge control, making it easier for plant foliage and roots to absorb and target unwanted weeds. Ideal solution for sedges that are hard to manage since it may be applied as broadcast and spot treatment. For better use in turfgrass, can be tank mixed with other herbicides. Comes in a 1 lb. bottle.

DIRECTIONS FOR USE ON ESTABLISHED TURFGRASS

Celero Herbicide can be applied to established residential and commercial turfgrass for control of nutsedge and selected broadleaf weeds. Apply Celero Herbicide to turfgrass growing in areas such as apartment complexes, golf courses, sod farms, roadsides, sports fields, campgrounds, office complexes, parks, parking areas, recreational sites, schools, residential lawns, and commercial areas. When applied as directed, the following established turfgrass species are tolerant to Celero Herbicide.

SURFACE WATER ADVISORY: Imazosulfuron and its degradates may impact surface water quality through spray and runoff of rainwater. This is especially true for poorly draining soils and soils with shallow groundwater. Imazosulfuron and degradates are classified as having a high potential for reaching surface water via runoff for several months or more after application. A level well maintained vegetative buffer strip between areas to which this product is applied and surface water features such as ponds, streams, and springs will reduce the potential loading of imazosulfuron and degradates from runoff water and sediment. Runoff of this product will be reduced by avoiding applications when rainfall is forecast to occur within 48 hours. 

GROUNDWATER ADVISORY: Imazosulfuron and several of its degradates have properties and characteristics associated with chemicals detected in groundwater. These chemicals may leach into groundwater if used in areas where soils are permeable, particularly where the water table is shallow. 

ENVIRONMENTAL HAZARDS: Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the mean high water mark. Do not contaminate water by disposing of equipment wash waters or rinsate. 

RESISTANCE MANAGEMENT

Celero Herbicide is a Group 2 herbicide. Any weed population may contain plants naturally resistant to Group 2 herbicides in various mode of action classes. Resistant biotypes may eventually dominate the weed population if the same class of chemistry/mode of action herbicides is used repeatedly in the same field or in successive years. These resistant biotypes may not be adequately controlled by herbicides in a mode of action class for which resistance has developed. A gradual or total loss of weed control may occur over time. Other resistance mechanisms that are not linked to the site of action, such as enhanced metabolism, may also exist. Appropriate resistance management strategies should be followed.

To Delay Herbicide Resistance Consider:

• Making applications at the specified label rate at the specified stage of weed growth.

• Avoiding the use of herbicides that have a similar target site mode of action in consecutive years.

• Basing herbicide selection on an Integrated Pest Management (IPM) program that includes scouting, record keeping, and consideration of cultivation practices, water management, weed-free crop seed, crop rotation, and other chemical or cultural control practices. 

• Monitoring the treated weed population for resistance development and reporting suspected resistance.

• Contacting your local extension or crop expert (advisor) for any additional pesticide resistance management and/or IPM recommendations for specific crops and weed biotypes.

SPRAYER PREPARATION

Before applying Celero Herbicide, start with clean, well-maintained application equipment. Calibrate spray equipment before each use and check periodically during application. The spray tank, hoses, and booms must be cleaned to ensure no residue from the previous spraying operation remains in the sprayer. The spray equipment must be cleaned according to the manufacturer’s directions for the last product used before the equipment is used to apply Celero Herbicide. If two or more products were tank mixed prior to Celero Herbicide application, follow the most restrictive cleanup procedure.

MIXING INSTRUCTIONS

1. Fill clean spray tank 1/2 to 2/3 of the desired level with clean water.

2. While agitating, slowly add the Celero Herbicide to the spray tank. A rippling or rolling action on the water surface will occur as the result of an effective agitation.

3. If tank mixing Celero Herbicide with other labeled pesticides, add water soluble bags first, followed by dry formulations, flowable, emulsifiable concentrates and then solutions.

4. Add any required adjuvants (see Adjuvants section below).

5. Fill spray tank to the desired level with water. Continue to agitate until all spray solution has been applied.

6. Mix only the amount of spray solution that can be applied the day of mixing. Apply Celero Herbicide within 24 hours of mixing. 

Sensitive Areas

Only apply this pesticide when the potential for drift to adjacent sensitive areas (e.g., bodies of water, known habitat for threatened or endangered species, non-target plants) is minimal (e.g., when the wind is blowing away from the sensitive areas).

BROADCAST APPLICATIONS

Apply 8 to 14 oz of Celero Herbicide (0.38 to 0.66 lb ai/A) plus 0.25% v/v of a non-ionic surfactant (1 quart per 100 gallons of spray solution) per broadcast acre as a postemergence (after weed emergence) application. Apply Celero Herbicide for postemergence application use after nutsedge has reached the 3-leaf stage of growth. Use the low rate for light infestations and the high rate for heavier nutsedge infestations. Only use a non-ionic surfactant that contains at least 80% active ingredient.

When applied at 8 oz, make a second application at 21 days after the initial treatment. At rates greater than 8 oz (up to 14 oz) product per acre, the second application of Celero Herbicide may be made, if needed, 21 days after the initial treatment. Apply the second application using the above-mentioned rate guidelines when the nutsedge reaches the 3-leaf stage of growth.

To ensure thorough coverage, use 20 to 30 gallons of spray solution per acre. Use a minimum of 30 gallons per acre if dense vegetation is present, such as golf course rough areas. Select nozzle according to “Nozzle type” section above. 

SPOT TREATMENTS

Mix 0.25 to 0.33 oz (0.011 to 0.015 lb ai) of Celero Herbicide in one to two gallons of water to treat 1,000 square feet. Add 2 teaspoons (1/3 fl oz) of non-ionic surfactant per gallon of water. Occasionally shake the spray solution while spraying to ensure the spray solution remains well mixed. Spray the target weeds until the leaves are wet.
