Do not apply to zoysiagrass just emerging from dormancy. 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. 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 listed other broadleaf weeds are young and actively growing with adequate soil moisture for best results.

How much to use: See the following table of calculating the correct amount of product to use for the area to be treated. The maximum application rate is 4 fl oz of product per 1,000 sq ft per application (0.74 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 8 fl oz of product per 1,000 sq ft (1.48 lb 2,4-D acid equivalent per acre), excluding spot treatments. Measurement calculations: Total lawn area in square feet = length x width. How to use: 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 towards 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 up to 21,333 sq ft of St. Augustinegrass, 16,000 sq ft of other warm season grasses and 8,000 sq ft of cool season grasses. Calculate square feet by multiplying length by width. Refer to sight gauge to guide coverage (example: when bottle is half empty, you should have covered half the area). (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 a cool area away from heat, sunlight or open flame.

Use tips: Some hard-to-kill weeds may require re-treatment. Waft at least two weeks between applications - some weeds can take that long to die. Spray during growing season when weeds are actively growing. For best results, mow lawn two to three days before treating weeds. To avoid risk of lawn injury, do not spray drought-stressed lawns. Watering immediately after treatment may wash away effectiveness. Wait until newly seeded grass is well established or after the third mowing before applying this product. Treated areas may be reseeded three to four weeks after application. Adjust nozzle to produce a coarse spray. Coarse sprays are less likely to drift. Avoid fine mists. Application to zoysia lawns when they are emerging from dormancy in the spring may cause damage. Overapplication, especially at 90 degrees F or higher, may cause damage. Application to Bermudagrass may cause temporary yellowing when applied at 90 degrees F or higher, but full recovery can be expected. Storage and Disposal: Pesticide Storage: Store in a cool, dry area away from heat or open flame. Where to use: Lawns ��� treats bluegrass, fescue zoysia(do not apply to zoysiagrass just emerging from dormancy), Bermuda, perennial ryegrass. When to use: For best results, apply between 45 degrees F - 90 degrees F. Above 45 degrees F, the better the weeds will be able to absorb the product. Lawn damage could happen above 90 degrees F.

Works great

I have found this to be very effective without harming the grass. You will see results in several days. Found it works on all kinds of weeds..Attaching to hose makes sure you get the proper mix of water to chemicals. I use the concentrate refill to use the unit again.
