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
**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.
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 at the same rate with a 14-day interval 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.
YELLOW NUTSEDGE:
Early summer:
Two applications of this product are required when the yellow nutsedge plants are 3 to 6 inches tall. Apply the second application at the same rate 14 days later.
BROADLEAF WEEDS:
Spring:
Apply when dandelion, plantain, buttercup, speedwell, knotweed and other broadleaf weeds are young and actively growing with adequate soil moisture for best results.
Fall: Apply when henbit, chickweed, white clover, ground ivy, lawn burweed and other broadleaf weeds are young and actively growing with adequate soil moisture for best results.

Visual symptoms and time to kill will depend on weed type, temperature and application rate.
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.

DIRECTIONS FOR HOSE-END SPRAYER

  1. Shake container well before using.
  2. Connect a garden hose to the sprayer nozzle. Make sure switch is fully forward in the “OFF” position.
  3. Turn on water at faucet. Extend hose to the farthest area to be treated and work back toward the faucet so you don’t come in contact with the treated area.
  4. Remove safety tab from sprayer’s right side by pulling straight out. Keep for future reuse.
  5. To BEGIN spraying, point nozzle toward treatment site and pull switch backwards with thumb toward hose connection. Water will automatically mix with the product.
  6. Spray until wet to control weeds. Walk at a steady pace, working back toward the faucet while spraying, using an even sweeping motion, slightly overlapping treated areas. One quart will treat 5,000 sq ft of Southern or Northern grasses.
  7. To STOP spraying, push switch forward with thumb toward nozzle. Turn water off at faucet. To relieve pressure before removing nozzle from hose, pull switch backwards with thumb toward hose connection until water stops spraying.
  8. To STORE unused product, make sure switch is fully forward in the “OFF” position.
  9. Reinstall safety tab into sprayer’s right side. With sprayer in the full “OFF” position, push tab into position.
  10. Place in cool area away from heat, sunlight or open flame.
