Hi-Yield 2, 4-D Selective Weed Killer is a selective post-emergent liquid concentrated herbicide that controls various broadleaf weeds and other noxious plants. Perfect to use in drainage ditch banks, pastures, lawns, on-crop areas, ponds, and on turfgrass in lawns, cemeteries, golf courses, parks, and other grassy places. It is best applied during warm weather on established lawns when weeds are actively growing. Hi-Yield 2,4-D is proven to control broadleaf weeds such as nettle, plantains, alder, poison ivy, bitterweeds, elderberry, chickweeds, ground ivy, sumac, honeysuckle, water lily, wild onion, and wild carrot. For better results, some species like perennial sowthistle, blue lettuce, bindweed, bur ragweed, and Canada thistle may require more than one application. Note that restrictions may apply to aquatic weed control in your area. Make sure not to apply when the temperature exceeds 90 degrees Fahrenheit or winds exceed 15 mph.

GENERAL PRECAUTIONS AND RESTRICTIONS
Do not apply this product through any type of irrigation system. Do not contaminate water used for irrigation or domestic purposes.
Excessive amounts of this product in soil may temporarily inhibit seed germination and plant growth. Do not use the same spray equipment for applying other materials to 2,4-D susceptible crops as injury may result. It is best to use a separate sprayer for the application of insecticides and fungicides.

Generally, the lower dosages given will be satisfactory for young, succulent growth of sensitive weed species. For less sensitive species and under conditions where control is more difficult, the higher dosages will be needed. Apply this product during warm weather when weeds are young and growing actively. Use enough spray volume for uniform coverage by the ground application. If only bands or rows are treated, leav- ing middles unsprayed, the dosage per crop per acre is reduced pro- portionately. Do not apply when the temperature exceeds 90 degrees Fahrenheit.
Mix this product only with water. Add about half the water to the mixing tank, then add this product with agitation, and finally the rest of the water with continuous agitation. Note: Adding oil, wetting agent, or other surfactants to the spray may increase effectiveness on weeds but also may reduce selectivity to crops resulting in crop damage.
GRASSES (Established Pastures and Rangeland)
In established pastures and rangelands, use 1 gallon of this product in 15 gallons of water per acre per application per site. For small areas, use 3 to 4 fluid ounces (6 to 8 Tablespoons) per 1,000 square feet; mix 1 to 3 gallons of water and apply uniformly over the area. Apply preferably when weeds are small and growing actively before the bud stage. Fall or spring is the best time to treat. Repeated treatments may be needed for less susceptible weeds, but no more than 2 applications per year. Treatment will kill or injure Alfalfa, Sweet Clover and other Legumes. White Clover (including Ladino) may be injured by the light application but recovers; repeated treatments will kill it. In some areas Dichondra, Bent, Carpet, Buffalo, and St. Augustine Grasses may be injured. Usually, colonial bents are more tolerant than creeping types; velvets are most easily injured. Where Bentgrass predominates, make 1 application of 1/2 gallon per acre at 30-day intervals. Maximum rate per application is 2.5 gallons per acre, limited to 2 applications per year. A minimum of 30 days between applications. The preharvest interval (PHI) is 7 days (cut forage for hay). For susceptible annual and biennial broadleaf weeds: Do not apply more than 1.0 lbs ae per acre per application.
For moderately susceptible biennial and perennial broadleaf weeds, difficult to control weeds and woody plants: Do not apply more than 2.0 lbs ae per acre per application.
Note: If the grass is to be cut for hay, Agricultural use Requirements for the Worker Protection Standard are applicable. For program lands, such as the Conservation Reserve Program, consult program rules to determine whether grass or hay may be used. The more restrictive requirements of the program rules or this label must be followed.
ORNAMENTAL TURF (Lawn, Golf Courses, Cemeteries, Parks and Other Grass Areas)
Use 1 gallon of this product in 15 gallons of water per acre. Treat when weeds are young and growing well. Do not use on dichondra or other herbaceous ground covers. Do not use on creeping grasses such as Bent except for spot treatment nor on freshly seeded turf until the grass is well established. Reseeding of lawns should be delayed following treatment. With spring application, reseed in the fall. With fall application, reseed in spring. Legumes are usually damaged or killed. Thoroughly wet weeds when applying this mixture. Bindweed, Whitetop, Perennial Sow Thistle, Blue Lettuce, Bur Ragweed, Canada Thistle, and other noxious perennials somewhat resistant to 2,4-D will require repeated treatments to kill. Maximum rate per application is 1.8 gallons per acre per season, limited to 2 applications per year. The maximum seasonal rate is 3.5 gallons per acre, excluding spot treatments.
NON-CROP AREAS (Airfields, Rights-of-Way, Fencerows, Roadsides, Vacant Lots Drainage Ditch-Banks, and Similar Places)
Use 1 gallon of this product in 15 gallons of water per acre. Treat when weeds are young and growing well. Do not use on Dichondra or other herbaceous ground covers. Do not use on creeping grasses such as Bent except for spot treatment nor on freshly seeded turf until the grass is well established. Reseeding of lawns should be delayed following treatment. With spring application, reseed in the fall. With fall application, reseed in spring. Legumes are usually damaged or killed. Thoroughly wet weeds when applying this mixture. Bindweed, Whitetop, Perennial Sow Thistle, Blue Lettuce, Bur Ragweed, Canada Thistle, and other noxious perennials somewhat resistant to 2,4-D will require repeated treatments to kill. Maximum rate per application is 2.5 gallons per acre per year, limited to 2 applications per year. Minimum of 30 days between applications.
To control small areas of woody plants, such as Willows, Honeysuckle, Virginia Creeper, Alders and others susceptible to 2,4-D, use 1 gallon of this product in 25 gallons of water; spray to thoroughly wet plants when in full leaf. Retreat as necessary for control of regrowth and seedlings. In general, it is better to cut tall woody growth and spray suckers when 2 to 4 feet high. Maximum rate per application is 4.75 gallons per acre per year, limited to 1 application per year.
Applications to non-cropland areas are not applicable to the treatment of commercial timber or other plants being grown for sale or other commercial use, or for commercial seed production, or for research purposes.
CONTROL OF SOUTHERN WILD ROSE: On roadsides and fencerows, use 1 gallon of this product plus 4 to 8 fluid ounces of an agricultural surfactant per 25 gallons of water and spray thoroughly as soon as the foliage is well developed. Two or more treatments may be required.
SPOT TREATMENT IN NON-CROP AREAS: To control broadleaf weeds in small areas with a hand sprayer, use 1 pint (4 fluid ounces) of this product in 3 gallons (3/4 gallon) of water and spray to thoroughly wet all foliage.
AQUATIC WEED CONTROL (Surface Application to Floating and Emergent Weeds)
Boat Application: Use 1 gallon of this product in 25 gallons of water per acre.
Uniform coverage is essential. Avoid submerging plants after treatment. The application should be made when leaves are fully developed above the water line and plants are actively growing.
Treatment of aquatic weeds can result in oxygen loss from the decomposition of dead weeds. This loss can cause fish suffocation. Therefore, to minimize this hazard, treat 1/3 to 1/2 of the water area in a single operation and wait at least 21 days between treatments. Begin treatments along the shore and proceed outwards in bands to allow fish to move into untreated areas.
The maximum rate per broadcast application is 4.7 gallons per surface acre, limited to applications is 2 per year. Do not make a broadcast application within 21 days of previous broadcast application. Spot treatments are permitted.
Apply to emergent aquatic weeds in ponds, lakes, reservoirs, marshes, bayous, drainage ditches, non-irrigation canals, rivers, and streams that are quiescent or slow moving
Coordination and approval of local and state authorities may be required, either by letter of agreement or issuance of special permits for aquatic applications.
I read the review by Sara, who stated that the % of active ingredient was different in the quart and gallon sizes. I was curious, so I emailed Do My Own and asked them. According to Do My Own, there is NO difference in % active ingredient in the quart and gallon sizes.
I ordered 2,4-D and had my order is like two days. However when I opened it, it was a bug control product. I called customer service and mailed me another gallon in the next two days. I received a return postage for the incorrect product - so just wanted to say the customer service was outstanding. The product works good, it doesn't harm the grass. I have applied twice to the area. The weather has been cooler than normal and I am wondering if it was warmer, if the results would have been faster.
