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


Do not apply this product through any type of irrigation system. Do not spray on carpetgrass, dichondra nor lawns or turf where desirable clovers are present. Use only lawn type sprayers. Do not exceed specified dosages for any area. Do not spray while grass is emerging from dormancy. Do not apply to newly seeded grasses until well established. Do not spray when air temperatures exceed 85 degrees F. Seed can be sown 3 to 4 weeks after application. Some injury can be expected to turf when used on centipedegrass or St. Augustinegrass lawns; only spot spray weeds only on these types of grasses. Clover present will be damaged if sprayed. After using this product, clean sprayer with soap or detergent and water, and rinse thoroughly before applying other pesticides. Failure to observe the above precautions may result in injury. 

Do not use this product on or near desirable plants, including contact of spray on exposed root systems or adventitious shoots within the drip line of desirable trees and shrubs, since injury may result.


Bentgrass, Centipedegrass, St. Augustinegrass, and Buffalograss - Apply Trimec Broadleaf Herbicide Bentgrass Formula at 3 to 4 pints of product per acre (1.1 to 1.5 fl. oz./1,000 sq. ft.) in sufficient water for uniform coverage. If hardy weeds persist, make a second application after 30 days. Maximum control of weeds will be obtained from spring or early fall applications when weeds are actively growing. Avoid applying during long excessively dry or hot periods unless adequate irrigation is available. If the application is made when the soil is quite warm, use reduced rates to reduce potential injury. Do not irrigate within 24 hours of application. Do not apply to newly seeded turf until the second or third mowing. Seed can be sown 3 to 4 weeks after herbicide application. Do not use on dichondra. Do not apply this product to 'Floratam' St. Augustinegrass.

If dandelions persist spot treatments with a single nozzle hand sprayer are recommended. Do not overdose bentgrass, In closely mowed bentgrass (putting and bowling greens) apply Trimec Broadleaf Herbicide Bentgrass Formula at a maximum rate of 1 fl. oz. of product per 1,000 square feet preferably in May or through September. Any yellowing will disappear after about one week.

For hard-to-kill summer weeds, use 6 pints of product per acre. Do not apply this rate to bentgrass, centipedegrass or St. Augustinegrass.

Limitations on broadcast treatments for ornamental turfgrass:

The maximum application rate is 6.0 pints of product per acre per application. The maximum number of broadcast applications is limited to 2 per year with a minimum of 30 days between applications. The maximum seasonal rate is 12.0 pints of product per acre, excluding spot treatments.

Limitations on spot treatments to residential turfgrass:

Spot treatment is defined as a treatment area no greater than 1,000 sq. ft. per acre. The maximum application rate is 1.5 fl. oz. per 1,000 sq. ft. per application. The maximum number of spot treatments is limited to 2 per year with a minimum of 30 days between applications. 

Note: Care should be taken to avoid overdosing bentgrass or injury may result. High spray volumes will aid in obtaining uniform coverage. If hand type sprayers are used, it is preferable to use a single nozzle sprayer rather than a multiple nozzle boom. Sweeping movements with a multiple nozzle boom will result in heavy over-application and subsequent turf discoloration or injury.

Spray Drift Management

A variety of factors including weather conditions (e.g., wind direction, wind speed, temperature, relative humidity) and method of ground application can influence pesticide drift. The applicator must evaluate all factors and make appropriate adjustments when applying this product.

Droplet Size

Use only Medium or coarser spray nozzles according to ASAE (S 572) definition of standard nozzles or a volume mean diameter of 300 microns or greater for spinning atomizer nozzles.

Wind Speed

So not apply at wind speeds greater than 10 mph. Only apply this product if the wind direction favors on-target deposition and there are not sensitive areas (including, but not limited to, bodies of water, known habitat for nontarget species, nontarget crops) within 250 feet downwind.

Temperature Inversions

If applying at wind speeds less than 3 mph, the applicator must determine if: a) conditions of temperature inversion exist, or b) stable atmospheric conditions exist at or below nozzle height. Do not make applications into areas of temperature inversions or stable atmospheric conditions.

Susceptible Plants

Do not apply under circumstances where spray drift may occur to food, forage, or other plantings that might be damaged or crops thereof rendered unfit for sale, use or consumption. Susceptible crops include, but are not limited to, cotton, okra, flowers, grapes (in growing stages), fruit trees (foliage), soybeans (vegetative stage), ornamentals, sunflowers, tomatoes, beans, and other vegetables, or tobacco. Small amounts of spray drift that might not be visible may injure susceptible broadleaf plants.
