Do not apply within 25 ft rivers, fish ponds, lakes, streams, reservoirs, marshes, estuaries, bays and oceans. To prevent product runoff, do not overwater the treated area(s) to the point of runoff or apply when raining or when rain is expected that day. Rinse applicator over lawn area only. Where to use: This product is intended for use by homeowners on residential lawns including. Cool season turfgrass: Kentucky bluegrass; perennial bluegrass; fescue spp., including tall, red and fine leaf fescues; bentgrass. Warm season turfgrass: Bermudagrass; bahiagrass; zoysiagrass (Do not apply to zoysiagrass just emerging from dormancy, as it may result in lawn damage.); St. Augustinegrass (Do not use on floratam or bitterblue varieties of St. Augustinegrass. Do not this product on carpetgrass, dichondra, legumes or lawns containing clovers.); centipedegrass. When to use. (Visual symptoms and time to complete kill will depend on weed type, temperature and application rate): Apply when daytime temperatures are between 45 degrees F and 90 degrees F. 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. Fall: Apply when henbit, chickweed, white clover, ground ivy, lawn burweed and other listed 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. 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. Application Rates for Lawns Using the quickflip Sprayer: Turfgrass: St. Augustinegrass (Do not use on floratam or bitterblue varieties of St. Augustinegrass: Total treated area for 32 fl oz (1 quart) (Up to 21,333 sq ft); Amount of product applied per 1,000 sq ft (1.5 fl oz). Bermudagrass, bentgrass and centipedegrass: Total treated area for 32 fl oz (1 quart) (Up to 16,000 sq ft); Amount of product applied per 1,000 sq ft (2 fl oz). Kentucky bluegrass, fescue spp., perennial ryegrass, zoysiagrass (Do not apply to zoysiagrass just emerging from dormancy) and bahiagrass: : Total treated area for 32 fl oz (1 quart) (Up to 8,000 sq ft); Amount of product applied per 1,000 sq ft (4 fl oz). 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.

Super easy to use weed killer
The best thing about this weed killer is how easy it is to use. You attach it to your hose and you spray the areas with weed issues. I also love that it doesn't kill the grass like other weed killers. It isn't the fastest to kill, it takes a few days, but it is effective. I usually do one spray and if I have have any left in the bottle, I do a follow-up spray the next day.

It works and it's easy to use!
I had a large area of lawn that was just absolutely littered with weeds of various types, including dandelion and crabgrass, among others. I did two applications of this product over a period of 3-4 months, the second application being to cover places that I missed. It kills the weeds. The thing that I love about this is that you can cover such a wide area with the spray. I had previously been using a pump sprayer, which would have taken me 2 hours to do what this application method handles in hardly no time. It is just so easy!

The only week killing that I use
This is the best weed killer that I had used. I never use it when the temperature is in the 100's. It will ruin your lawn if you use it during those temperatures. I use it when the temperature is in the 70's to 80's. It kills all the weeds and not the grass. I have been using it for years and have no need to try another brand
