BNVrRONllBlll'l'AL HAZAlUlS 
This product is toxic to aquatic invertebrates. Drift or runoff may adversely affect 
aquatic invertebrates and nontarget plants. Do not apply directly to water, or to 
areas where surface water is present or to intertidal areas below the mean high water 
mark. Do not apply directly to flowers,· fruits, vegetables, grapes, ornamentals, 
cotton or other desirable plants. Do not apply when weather conditions favor drift 
from target area. (Coarse sprays are less likely to drift.) Vapors from this product 
may injure susceptible plants in the immediate vicinity. Clean and rinse spray 
equipment using soap or detergent and water or suitable chemical cleaner, and rinse 
thoroughly before reuse for other spraying. It is best to use a separate sprayer for 
application of insecticides and fungicides. Dc not contaminate water when disposing 
of equipment washwaters. Do not apply this product through any type of irrigation 
system. Do not contaminate domestic or irrigation waters. Excessive amounts of this 
product in the soil may temporarily inhibit seed germination and plant growth. 
Most cases of groundwater contamination involving phenoxy herbicides such as 2,4-D 
have been associated with mixing/loading and disposal sites. Caution should be 
exercised when handling 2,4-D pesticides at such sites to prevent contamination of 
groundwater supplies. Use of closed systems for mixing or transferring this ~esticide 
will reduce the probability of spills. Placement of mixing/loading equipment o'n an 
impervious pad to contain spills will help prevent groundwater contamination~·~~

application. Do not enter treatment areas until spray has dried. 
General Directions - All broadleaf plants do not respond the same. Young and actively 
growing weeds are easier to kill and the lower dosages may be used here. For the less 
sensitive species and under conditions where kill is more difficult, the higher dosages ( 
should be used. -
Use 2,4-0 L.V. 2 Ester for control of the following weeds: 
Bitterweed, Broomweed, Croton weed, Dandelion, Docks, Dogfennel, Fanweed, Kochia, 
Lambsquarters, Mallow, Marshelder, Mustards, Peppergrass, Pigweed, Plantains, Ragweed, 
Shepherdspurse, Tarweed, Thistles, Vetch, Wild carrot, wild garlic, Wild morningglory, 
Wild onion, Wild radish, many other broadleaved weeds; Alder, Buckbrush, Coastal sage, 
Elderberry, Hazel, Sand sagebrush, Sand shinnery oak, Sumac, Willow, and certain other 
woody perennials.

• • Mixing Dit&~tions - When used on crops at the higher rates recommended 2,4-0 L.V. 2 Ester 
may caus~' ~()tn.e injury to crop plants, especially if crop is growing rapidly. However, 
where wee6s'~re a serious problem, weed control will often offset crop damage. Do not 
overdose o~ use o~'c~~s not recommended on this label. In preparing the mixture, add 
half the, i·~ttqired' water to the tank. Begin agitation and add 2,4-0 L. V. 2 Ester and then 
the rest 0'£' water. ' t, , •

Weeds in c .. :;rr. - P03':. -Emergence: Use 3/4 pint 2,4-0 L. V. 2 Ester in the amount of water 
necessary ,~o cover 1; acre. If weeds are sensitive, dosage can be reduced to 1h pint while 
more resi~bant weeds may require dosage of 1 pint. Apply spray as soon as majority of 
weeds ha~·germinated. Drop nozzles should be used after corn is 10 inches tall in order 
to keep spray off corn leaves. Do not apply from tasseling to dough stage. Pre-Emergence 
Applicat~cn.· Use 2 to 4 quarts 2,4-0 L.V. 2 Ester in 10 to 20 gallons water per acre. 
Apply after planting anytime, but before corn emerges. Do not treat light sandy soils.

Riverdale 2,4-D L. V. 2 Ester Page 5 
Weeds in Spring Wheat and Barley - Use 1 pint 2,4-6 L.V. 2 Ester in necessary water to 
spray one acre. Make spray application when grain is in full tiller stage (6 to 8 in. 
tall) until the early boot stage. Injury can occur if sprays are applied to young 
seedling or when grain is in the boot or shot blade stage. Dosages may be increased ~ 
pint for more resistant weeds or decreased ~ pint for easy to kill weeds. 
Weeds in Winter Wheat and Rye - Use 1 to 1-1/2 pints 2,4-D L.V. 2 Ester in necessary water 
to spray one acre. Make application in the Spring from the fully tillered to the jointing 
stages. 
Weeds in Oats Not Underseeded with Legumes - Do not use over 1 pint 2,4-D L.V. 2 Ester in 
necessary water to cover one acre. Since recommendations vary in states as to proper time 
of application, follow local state recommendations as to timing of spray. 
Weeds in Pasture - To control most broadleaf weeds, use 1-1/2 to 2 quarts 2,4-D L.V. 2 
Ester in sufficient water to cover one acre. Apply when weeds are growing best. For the 
control of wild garlic and Wild onion, increase dosages to 4 to 6 quarts per acre. Make 
three applications in Fall-Spring-Fall or Spring-FaIl-Spring sequence. Do not apply to 
creeping grasses or freshly seeded pastures. Most legumes are also damaged or killed. 
Weeds in Ornamental Lawns and Turf - To control most broadleaf weeds in institutional, 
)rnamental and residential/domestic sites, use 1-1/2 to 2 quarts 2,4-D L.V. 2 Ester in 
dufficient water to cover one acre per application per site. Apply when weeds are 
growing best. For the control of Wild garlic and Wild onion increase dosage to 4 quarts 
per acre. Make two applications in Fall-Spring or Spring-Fall sequence. Do not apply to 
creeping grasses or freshly seeded lawns. 
Roadside and General Weed Control - Use 2 to 3 quarts 2,4-D L.V. 2 Ester in 100 gallons of 
water. Apply as a wetting spray covering all foliage thoroughly. This application is 
recommended along roads, rights-of-way, fence rows, and in pole yards and similar non-crop 
areas. 
Woody Plant Control - For 2,4-D susceptible brush like Willow, Elderberry, Sumac, apply a 
drenching spray using 3 quarts 2,4-D L.V. 2 Ester in 50 gallons water. Wet thoroughly, 
including foliage, bark and shoot stems down to ground level. This use should be confined 
to non-crop areas described under directions for Roadside and General Weed Control. 
Knapsack Applications - For spot treatment of weeds, mix one cupful 2,4-D L.V. 2 Ester in 
3 gallons of water and wet all foliage thoroughly to runoff stage. 
STORAGE AND DISPOSAL
