Crew Specialty Herbicide is uniquely made with a 2-in-1 formula for eliminating unwanted weeds in turfgrasses, landscape ornamentals, and non-crop areas. Contains dithiopyr and isoxaben as its two active ingredients, which are known for controlling and killing a wide range of broadleaf weeds and grasses. This pre-emergent herbicide works against over 120 types of grassy and broadleaf weeds. Its ultra-low dust granule leaves no stain after use. It offers versatility since it may be applied to a wide range of plants including more than 410 ornamentals, and it may be applied on both warm-season and cool-season turfgrasses.

Environmental Hazards

This product is toxic to fish and highly toxic to other aquatic organisms including oysters and shrimp. Use with care when applying to turf areas adjacent to any body of water. Drift and runoff from treated turf may adversely affect aquatic organisms in adjacent aquatic sites. 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 apply when weather conditions favor drift from treated areas. Do not contaminate water when disposing of equipment washwaters.

Ground Water Advisory: This pesticide has properties and characteristics associated with chemicals detected in ground water. This chemical may leach into ground water if used in areas where soils are permeable, particularly where the water table is shallow.

Surface Water Advisory: This pesticide may impact surface water quality due to runoff of rain water. This is especially true for poorly draining soil and soils with shallow ground water. This product is 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 load of isoxaben from run off water and sediment.

Directions for Use

It is a violation of Federal law to use this product in a manner inconsistent with its labeling.

Read all Directions for Use carefully before applying

REFORMULATION OR REPACKAGING OF THIS PRODUCT IS PROHIBITED.

Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your state or tribe, consult the agency responsible for pesticide regulation.

Landscape Ornamentals Use

Landscape Application Instructions

Apply Crew prior to weed seed germination in the early spring or fall or following a complete weed removal. Repeat application after three months (maximum residual) during the growing season. Apply Crew at 150 pounds per acre per application, with a maximum of two applications per year. Crew is not registered for use on vegetables, edible fruit bearing crops or bedding plants.

For optimum results remove established weed by handweeding, mechanical methods or with postemergence herbicides prior to application of Crew. If applied to new plantings, irrigate with water to settle and firm up soil around roots.

To ensure optimal herbicidal response, water treated areas within 21 days of application if rainfall is not expected. A single rainfall or sprinkler irrigation of 0.5 inch is often required to activate this product. Mulch can be applied either prior to or after application.

In order for Crew to provide maximum preemergent weed control activity, use the following cultural practices. Prior to application, the bed or soil surface should be smooth and free of plant and weed debris (decaying leaves, clippings, dead weeds, etc.). Leaves and debris may be removed by blowing the area to be treated or by thoroughly mixing the debris trash into the soil through cultivation prior to herbicide application.

Specific Use Restrictions For Landscape Ornamentals:

• Do not reapply at less than a 3 month interval on ornamentals.
• Do not apply Crew to newly transplanted ornamentals, groundcovers until soil has settled around the roots.
• Do not apply while plants are producing a new flush of spring growth; tender, newly forming leaves are especially sensitive and may be injured by the herbicide.
• Do not apply to moist or wet foliage of ornamentals.
• Do not apply to plant types whose leaves channel the herbicide granules in the leaf base or crown area.
• Do not apply when extreme cold stress (35F or lower) is expected.
• Do not graze or feed forage from treated fields to livestock.
• Do not apply to vegetable or edible fruit bearing crops.
• Do not use on fruit trees that will bear fruit within one year of application. Non-bearing fruit trees are defined as trees including Citrus (oranges, grapefruit, etc.), pome fruits (apples, pears, etc) and stone fruits (cherries, peaches, etc.) which will not bear fruit for at least one year following application of Crew.
• Do not apply to bedding plants or flowering crops unless specified elsewhere on label.
• Do not disturb the soil surface following application, as the herbicide barrier will be broken, resulting in less than desirable results
• Do not apply to bare roots of ornamental plants as injury may result • Do not apply more than 150 pounds of this prouduct (0.375 lb dithiopyr and 0.75 lb isoxaben) per acre per application
• Do not apply more than 300 pounds of this product (0.75 pound dithiopyr and 1.5 pounds isoxaben) per acre per year
• Do not make more than 2 applications per year.

Treatment of Ornamental Species Not Listed on the Label for Crew Herbicide

When applied as directed under the conditions described on this label, ornamentals listed above have shown tolerance in field trials. However, Crew has not been tested on all cultivars of each species or under all possible growing conditions. Under your growing conditions, a limited number of plants should be treated for tolerance evaluations, prior to initiating large-scale applications. Follow directions given below to determine plant tolerance under your growing conditions prior to large scale use.

Users who wish to use Crew on plant species not specified on this label may determine the suitability for use by treating a small number of such plants at the specified rate. Prior to treatment of larger areas, the treated plants should be observed for any sign of herbicidal injury for 30 to 60 days of normal growing conditions to determine if the treatment is safe to the target plant species. The user assumes responsibility for any plant damage or other liability resulting from use of Crew on plant species not recommended on this label.

APPLICATION INSTRUCTIONS

Apply Crew using a drop or rotary-type spreader designed to apply granular fertilizer. Calibrate application equipment prior to use according to manufacturer's directions. Check frequently to be sure equipment is working properly and distributing granules uniformly. Do not use spreaders that apply material in narrow concentrated bands. Avoid skips or overlaps as poor weed control or plant injury may occur. More uniform application may be achieved by spreading half of the required amount of product over the area and then applying the remaining half in swaths at right angles to the first. When using a drop-type spreader, a splashboard mounted below the release point will provide more even granule distribution.

• For treating smaller areas or ornamental beds, a hand held or push-type rotary applicator such as a whirlybird or cyclone unit is recommended. For hand held units, walk and turn the crank at a constant rate of speed.
• A shaker-type applicator made from a small container with holes punched in the bottom is recommended for small, difficult to treat areas. Carefully measure the amount of product needed to avoid over application.

Broadcast Application Rates

Apply Crew at a broadcast rate of 150 lb (0.375 lb dithiopyr and 0.75 lb isoxaben) per acre (3.44 lb/1000 sq ft) in landscape ornamental applications or at a broadcast rate of 150 lb (0.375 lb dithiopyr and 0.75 lb isoxaben) to 200 lb (0.5 lb dithiopyr, 1.0 lb isoxaben) per acre (3.44 to 4.59 lb/1000 sq ft) in turfgrass applications.
