This product is toxic to fish. Drift or runoff may adversely affect fish and non­
target plants. Do not apply directly to water, or to areas where surface water is 
present or to intertidal areas below the mean high water maker. Vapors from this 
product may injure susceptible plants in the immediate vicinity. Use care to avoid 
spray contact or drift to 2,4-D susceptible plants such as cotton, tomatoes, flowers, 
grapes, fruit trees and ornamentals. Do not permit spray mist containing this product 
to drift onto them. Do not spray when the wind is blowing towards susceptible crops or 
ornamental plants. Use coarse sprays and/or low spray pressure to minimize drift. On 
cropland and along roadsides, do not exceed 20 psi pressure. Spray drift can be 
lessened by keeping the spray boom as low as possible, by spraying when wind velocity 
is low, and by stopping all spraying when wind exceeds 6 to 7 miles peer hour. 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 see a separate sprayer for application of 
insecticides and fungicides. Clean and rinse spray equipment using soap or detergent 
and water or suitable chemical cleaner, and rinse thoroughly before reuse for other 
spraying. Do 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 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 pesticide will reduce 
the probability of spills. Placement of the mixing/loading equipment on an impervious 
pad to contain spills will help prevent groundwater contamination. 
When using on Pastures and Rangeland Grasses there is a (1) 7 day pregrazing interval 
for dairy cattle: (2) 30 day preharvest interval for grass cut for hay; and (3) 3 day 
pre-slaughter interval for meat animals.

DXREC~XOHS FOR USB 
It is a violation of Federal law to use this product in a manner inconsistent with its 
labeling. READ ENTIRE LABEL BEFORE USING THIS PRODUCT. USE STRICTLY IN ACCORDANCE WITH 
LABEL PRECAUTIONARY STATEMENTS AND DIRECTIONS. 
Do not apply this product in a way that will contact workers or other persons, either 
directly or through drift. Only protected handlers may be in the area during application. 
For any requirements specific to your State or Tribe, consult the agency responsible for 
pesticide regulation. 
AGUCUL'l'URAL USB RBQUXRBllBll'l'S 
Use this product only in accordance with its labeling and with the Worker Protection 
Standard, CFR part 170. This Standard contains requirements for the protection of 
agricultural workers on farms, forests, nurseries, and greenhouses, and handlers of 
agricultural pesticides. It contains requirements for training, decontamination, 
notification, and emergency assistance. It also contains specific instructions and 
exceptions pertaining to the statements on this label about personal protective 
equipment (PPE) and restricted-entry interval. The requirements in this box only apply ~ 
to uses of this product that are covered by the Worker Protection Standard. 
Do not enter or allow worker entry into treated areas during the restricted entry 
interval (REI) of 12 hours. 
PPE is required for early entry to treated areas that is permitted under the Worker 
Protection Standard and that involves contact with anything that has been treated, such 
as plants, soil, or water, is: coveralls, chemical resistant gloves such as Barrier 
Laminate, Nitrile Rubber ~ 14 mils, Neoprene Rubber ~ 14 mils and Viton ~ 14 mils; 
shoes plus socks, and protective eyewear. 
The requirements in this box apply to uses of this product that are NOT within the 
scope of the Worker Protection Standard for agricultural pesticides (40 CFR part 170). 
The WPS applies when this product is used to produce agricultural plants on farms, f."" 
forests, nurseries, or greenhouses. \ 
For Turf use, do not allow people (other than applicator) or pets on treatment area 
during application. Do not enter treatment areas until spray has dried. 
This product is a low volatile ester especially prepared for use on crops and weeds where 
a susceptible crop in the near vicinity may be injured by a more volatile product. It is 
recommended for control of numerous broadleaf weeds and certain 2,4-0 susceptible woody 
plants without injury to most established grasses. For best results, apply this product 
as a water or oil spray during warm weather when young, succulent weeds or brush are 
actively growing. Application under drought conditions often will give poor results. The 
lower recommended rates will be satisfactory on susceptible annual weeds. For perennial 
weeds and conditions such as the very dry areas of the Western states where control is 
difficult, the higher recommended rates should be used. Deep-rooted perennial weeds such 
as Canada thistle and Field bindweed and many woody plants usually require repeated 
applications for maximum control. 
Unless otherwise directed, application rates should be 1 to 10 gallons of total spray by 
air or 5 to 25 gallons by ground application equipment. Higher gallonage may be used if 
desired to improve spray coverage. If band treatment is used, base the dosage rate on 
actual area to be sprayed. In either case, use the same amount of 2,4-0 recommended per 
acre. Although water quantities may vary due to different types of application equipment, 
sufficient water must be used to provide for complete and uniform coverage. When product

Riverdale Butoxy 2,4-D Low Volatile Ester Pag"e 5 
is used for weed control in crops, the growth stage of the crop must be considered. For 
crop uses, do not mix with oil, surfactants, or other adjuvants unless specifically 
recommended on label. To do so may reduce herbicide's selectivity and could result in 
crop damage. 
Aerial applications should be used only when there is no danger of drift to susceptible 
crops. Many states have regulations concerning aerial application of 2,4-D formulations. 
Consult local regulatory authorities before making applications. Although this product is 
a low volatile formulation, temperatures above 90"F vapors may damage susceptible crops 
growing nearby. 
Riverdale Butoxy 2,4-D Low Volatile Ester is especially prepared for use on crops and 
weeds where a susceptible crop in the near vicinity may be injured by a more volatile 
product.

TRBATMBRT :IN CORN AND SORGBOM - Use from 1/2 to 1 pint Riverdale Butoxy 2,4-D Low Volatile 
Ester with recommended amounts of water to make per acre applications. Time of 
application should be determined by weed growth with the ideal time after emergence of 
majority of weeds but before they have damaged the crop. The crop is most sensitive when 
growing fast and temperatures and moisture favorable for plant growth. As a general rule, 
the crop is less susceptible from 3 inches up to 10 inches. Use drop nozzle when corn or 
sorghum is over 10 inches tall. Do not apply from tasseling to dough stage. 
TRBATMBBT :IN SHALL QRAXNS - WHEAT, OATS, BARLBY AND RYE - Use from 1/2 to 1 pint Riverdale 
Butoxy 2,4-D Low Volatile Ester with recommended amounts of water to make per acre 
?plications for ground "equipment and airplane application. Good results have also been 
~tained with airplane application using diesel oil as the diluent instead of water. Make 
application after the crop is fully tillered until jointing is under way. Stop treatment 
before boot stage is reached. Spraying in small grain is frequently desirable after the 
crop has reached the milk stage. At such time annual and perennial weeds often interfere 
with harvesting and produce seeds which lower quality of threshed grain. Under such 
conditions use from 1 to 1-1/2 pints Riverdale Butoxy 2,4-D Low Volatile Ester with 
recommended amounts of water to make per acre applications. Ground equipment will cause 
some mechanical damage to the crop. When applying with plane, use dosage in 2 to 3 
gallons diesel oil. 
GBHBRAL BROADLBAJ' CONTROL ON PASTURES AND ON NON-CROPPBD LAND - Do not apply to clover or 
newly seeded pastures. The rates of applications for pastures and rangelands are per acre 
per application per site. 
ANNUAL WEEDS - Most annual broadleaf weeds can be controlled with 1 to 1-1/2 pints in 50 
to 100 gallons of water per acre. Make application when weeds are young and actively 
growing. 
New seedings of grass should not be treated until they are well established. For 
controlling annual weeds in farm yards, fence rows along highways and similar locations, 
use 1 quart in 5 to 10 gallons water per acre. Possible injury may occur to bentgrass St. 
Augustinegrass and clover. 
PERENNIAL WEEDS - Many of the perennial weeds in pastures, including ironweed, vervain and 
asters are moderately tolerant to 2,4-D. For control of these type weeds, use 1 quart 
Riverdale Butoxy 2,4-D Low Volatile Ester in 5 to 10 gallons water per acre. Make 
application not later than the bud stage and repeat treatment the following season.
