Apply when daytime temperatures are between 45°F and 90°F.- • Spring: Spray when broadleaf weeds are young and actively growing with adequate soil moisture for best results.
- • Fall: Spray when broadleaf weeds are young and actively growing with adequate soil moisture for best results. Fall applications will control weeds that may otherwise go dormant through the winter and resprout the following spring. For heavy grass weed pressure, apply a second application at the same rate, 14 days after the first application.
CRABGRASS (LARGE AND SMOOTH):
Spring and early summer: For the best results, apply this product from crabgrass emergence until the six-leaf stage (two tillers) or before the crabgrass is 3 to 4 inches tall. This period begins the first time that you can see crabgrass in your lawn. Use two applications with a 14-day interval between applications for dense populations.
FOXTAIL (GREEN, GIANT AND YELLOW):
Spring and early summer: For the best results, apply this product to foxtail during the early growth stages or when foxtail is 1 to 4 inches tall. Use two applications at the same rate with a 14-day interval for dense populations.

WHERE TO USE:
This product is intended for use by homeowners on residential lawns. Only apply this product to the following species of turfgrass:- • Cool season turfgrass: Kentucky bluegrass; perennial ryegrass; fescue spp., including tall, red and fine leaf fescues.
- • Warm season turfgrass: zoysiagrass**, Bermudagrass***, buffalograss
***Application to Bermudagrass may cause temporary yellowing or discoloration, but full recovery can be expected. Do not apply to Bermudagrass when daytime temperatures exceed 90°F.
USE TIPS:
- • Adequate moisture and mild environmental conditions enhance the performance of this product. Applications should be made to actively growing weeds. Apply when daytime temperatures are between 40°F and 90°F. Avoid applications of this product when turfgrasses are under stress since injury may result.
- • For newly seeded areas: Do not apply within four weeks after seedling emergence of Kentucky bluegrass, fine fescue blends and perennial ryegrass. Apply this product to newly seeded grasses when well-established (approximately six weeks after seedling emergence) or after the third mowing.
- • For newly sodded, sprigged or plugged areas: The application of this product to newly sodded, sprigged or plugged grasses should be delayed until three to four weeks after the sodding, sprigging or plugging operations.
- • Seeding: Turf species listed on this label can be seeded into the treated areas at four weeks after the application of this product.
- • Irrigation: Do not apply this product immediately before rainfall or irrigation. For best results, do not irrigate or water the turfgrass within 24 hours after application. If dry conditions exist, a scheduled irrigation or watering 24 hours before and 24 hours after application is recommended.
- • Mowing: Delay mowing two days before and until two days after the application of this product. Additional stress from low mowing heights may increase the possibility of turf injury. Clippings from the first three mowings should be left on the treated area. Do not use clippings from the treated areas as mulch or compost around flowers, ornamentals or trees in vegetable gardens.
HOW MUCH TO USE
See the following table for calculating the correct amount of product to use for the area to be treated.The maximum application rate is 6.5 fl oz of product per 1,000 sq ft per application (0.6 lb 2,4-D acid equivalent per acre per application).
The maximum number of broadcast applications is limited to two per year.
The maximum seasonal rate is 13 fl oz of product per 1,000 sq ft (1.2 lb 2,4-D acid equivalent per acre), excluding spot treatments.
MEASUREMENT CALCULATIONS:
Total lawn area in square feet = length x width.
EQUAL MEASURES:
1 fl oz = 2 Tbsp = 6 tsp | 4 fl oz = ½ cup | 16 fl oz = 1 pt
2 fl oz = 4 Tbsp | 8 fl oz = 1 cup | 32 fl oz = 1 qt
Amount of product to be diluted in 1 gal of water required to treat 500 sq ft of lawn with pressure sprayers
**Do not apply to zoysiagrass just emerging from dormancy, as it may result in lawn damage.
***Application to Bermudagrass may cause temporary yellowing or discoloration, but full recovery can be expected. Do not apply to Bermudagrass when daytime temperatures exceed 90°F.

SPOT TREATMENT:
To treat small areas or individual weeds, use a pressure sprayer for better control. Do not use a hose-end sprayer for spot treatments. Mix the indicated amount of product listed below with 1 gal of water for each 500 sq ft to be treated. Shake well before spraying. Spray the target weeds thoroughly. Nozzle adjustments may be necessary to deliver small spray droplets to the target weeds for uniform coverage.Amount of product to be diluted in 1 gal of water required to treat 500 sq ft of lawn with pressure sprayers

***Application to Bermudagrass may cause temporary yellowing or discoloration, but full recovery can be expected. Do not apply to Bermudagrass when daytime temperatures exceed 90°F.
ENTIRE LAWN TREATMENTS:
Three easy steps to mix and apply with hand-operated sprayers:- 1. Calculate the total lawn area to be treated. This is done by multiplying the length of the area by the width to obtain total square feet. Prepare only enough spray solution to treat the area calculated.
- 2. Prepare the spray mixture according to Table 1. Carefully measure the proper amount of product to treat 1,000 sq ft. If more or less than 1,000 sq ft is to be treated, adjust the amount of product accordingly.
- 3. Shake the spray solution before and during application. Use a spray pattern that gives small droplets without any fine mist.
BROADCAST TREATMENTS:
PRESSURE SPRAYERS:
Table 1. Amount of product to be diluted in 1 gal of water required to treat 1,000 sq ft of lawn with pressure sprayers:**Do not apply to zoysiagrass just emerging from dormancy, as it may result in lawn damage.
***Application to Bermudagrass may cause temporary yellowing or discoloration, but full recovery can be expected. Do not apply to Bermudagrass when daytime temperatures exceed 90°F.
DIAL-IN HOSE-END SPRAYERS WITH NO PRE-MIXING:
- 1. From Table 2 below, determine amount of product to be applied for each 1,000 sq ft of lawn.
- 2. Fill sprayer jar with enough concentrate to cover area to be treated. Do not add water to the sprayer jar.
- 3. Set dial on sprayer to the "Rate per Gallon" setting from Table 2 below.
- 4. Attach sprayer to garden hose. Extend hose to the farthest area of lawn to be treated and work back toward faucet so that you do not walk over treated areas. Apply evenly to lawn.
- 5. Unused product can be returned to the original container when completed.
**Do not apply to zoysiagrass just emerging from dormancy, as it may result in lawn damage.
***Application to Bermudagrass may cause temporary yellowing or discoloration, but full recovery can be expected. Do not apply to Bermudagrass when daytime temperatures exceed 90°F.
∞This assumes the sprayer delivers approximately 2.5 gal per 1,000 sq ft sprayed.
EXAMPLE: For Kentucky bluegrass: To treat 3,000 sq ft of lawn, measure 20 fl oz of product into sprayer jar. Do not add water. Set dial on 5 Tbsp or 15 tsp and apply uniformly on 3,000 sq ft of turfgrass. Check the directions you received when you purchased your sprayer for further details on the proper use of your dial sprayer. Directions are calculated assuming hose-end sprayer is used to spray about 2 gal of water/product mixture per 1,000 sq ft.
FOR CONCENTRATE-PLUS-WATER SPRAYERS OR HOSE-END SPRAYERS WITH PRE-MIXING:
For sprayers that require the addition of water as well as concentrate prior to application:- 1. From Table 3, determine amount of product to be applied for each 1,000 sq ft of lawn.
- 2. Pour product into sprayer jar to the required "fl oz" level.
- 3. Add the appropriate amount of water to the "gallons" level. Replace sprayer top on jar and shake well before spraying.
- 4. Attach sprayer to hose. Extend hose to the farthest area of lawn to be treated and work back toward faucet so that you do not walk over treated areas. Apply evenly to lawn.
**Do not apply to zoysiagrass just emerging from dormancy, as it may result in lawn damage.
***Application to Bermudagrass may cause temporary yellowing or discoloration, but full recovery can be expected. Do not apply to Bermudagrass when daytime temperatures exceed 90°F.
Example for Kentucky bluegrass: To treat 3,750 sq ft of lawn, pour 24 fl oz of product into sprayer jar. Add water to the 9 gal mark and apply uniformly on 3,750 sq ft of turfgrass. Check the directions you received when you purchased your sprayer for further details on the proper use of your sprayer.
