NOTE: Local conditions, crop varieties ilnd application requlations VillY and may 
affect usc of this horbicido. Consul-! loc,)! aqrlcultural expC:I'lmnnt station or L----­
extension service woed specialists and state regulatory ~qencies for recommenda-
tions In your area. 
TREATING S:I,ALL AREAS: One tablespconful of RIVERSIDE 2,4-0 BUTYL ESTER 6 In tt 1. ___ 
gallons of water Is about equal to 1 quart in 100 '-Iallons. 
NOTE: vlhen stored at temperatures be I ow f reez i n9, it may be necessary to warm L_ 
contents to 45°F and mix thoroughly before using. 
PREPARATION OF THE SPRAY: Fil I the spray tank with half the required amount of water, 
then add the recommended amount of RIVERSIDE 2.4-0 8UTYL ESTER 6 and continue fl II ing 
spray tank with bu I <lnce of water. Keep ag i tator runn i ng when f i I I i nq spray tank and 
dur i ng spray operat ions. Use enough spray vo I ume for un i form COVeril!)e. I n any case, • 
USe the same amount of :>,4-0 recommended per acre. For crop uses, DO NOT mix with 
oil, atraz I ne, surfactant or- other adjuvants un I ess spec if i ca II y recOI"IIIended on th I s 
label as this may reduce selectiVity to crops resulting in crop damage. 
TIME OF APPLICATION: Best results are obtained when RIVERSIDE 2,4-D BUTYL ESTER G 
is used on young ~!eeds that are actively growing. Applications of lower recOIMlended \ 
rates to susceptible annual weeds usually will be satisfactory, but for perennial -­
' .. eeds and other conditions, such as in very dry areas where ki II is difficult, use 
higher recommended rates. ~Ihen used as a selective spray on crops, the stage of growth 
of the crop must be considered. Some woody plants and weeds are hare to kill and 
repeat applications may be necessary. 
S~!ALL GRAINS (Wheat, Barley, Rye): Apply RIVERSIDE 2.4-D BUTYL ESTER 6 in sufficient 
water for unl form_ c;overa9..e on __ sma II gra i ns when fu Ily ti Ilered or stooled (Tfa -8-
inches ta II ), but befo·re the "boot" stage. DO NOT use on gra In undersown with legumes 
such as alfalfa or clovers, except where some legume injury can be tolerated. DO NOT 
graze or feed forage from treated fields within two weeks after treatment. See chart L/­
for recommended rates. 
for late season use to control large succulent weeds, apply 2/3 to 1 1/3 pints per 
acre in sufficient water for uniform coverage on small grain from dough stage to ~ 
harvest --Use only when weeds threaten to interfere with harvest operations. DO NOT ~ 
use treated straw for I ivestock feed. 
CORN: PREEr~ERGENCE-Use RIVERSIDE 2,4-D BUTYL ESTER 6 in 'iufficient water for uniform 7 
_caverage Best results are obtained when applied 3 to 5 days after planting, but betore 
corn emerges. 00 NOT apply to light, sandy soi Is. t.,...---". 
POSTEMERGENCE-Apply RIVERSIDE 2,4-D BUTYL ESTER 6 from emergence to tassel ing. When 
spraying corn taller- than 10 inches, use nozzle extensions (llcorn drops"), directing 
the spray at base of the corn plant to keep the spray off the leaves as much as 
possible. DO NOT apply from tassel emergence to dough stage. Crop injury is more 
likely to occur if corn Is growing rapidly under high temperature and high soil 
moisture conditions. Under such conditions, use the lowest recommended rate. Delay ~­
cultivation for 8 to 10 days after application to reduce stalk breakage re?ul~ing from 
temporary brittleness caused by 2,4-0. Hybrids vary in tolerance to 2,4-D.:~~ult 
local agricultural experiment station or extension service weed special ists r~ardlng':': 
the use of 2,4-D on your specific hybrid. See chart tor recommend rates. ...... :., •• ,

PASTURES: To control many broad leaved weeds in pastures. meadows and rangelands. use 
I 1/3 pints per acre of RIVERSIDE 2,4-0 BUTYL ESTER 6 in sufficient water to provide 
uniform application. Treat pastures when weeds are growing actively. DO NOT apply 
to newly seeded pastures unti I grass is \~cl I cstabl ished or after heading begins. '-­
DO NOT apply when grass is in "boot" to "mi Ik" stage if grass production is desired. 
Most legumes are usually injured or kil led at the rates recommended. For control 
of wi Id garlic and wild onion in pastures. apply I 1/3 to 2 quarts per acre in very 
early spring and repeat annually untl I weeds are eradicated. DO NOT graze dairy~ 
animals on treated areas within 7 days after treatment. 
\~OODY PLANT CONTROL: To contro I 2,4-0 suscept i b I e woody p I ants such as a I der, buck­
brush, elderberry, sumac and wil low on non-crop land and waste areas, uSe 1 1/3 to 
2 quarts of RIVERSIDE 2.4-0 BUTYL ESTER 6 in 100 gallons of water. Wet thoroughly /' 
al I parts of the plants, including foliage and stems, to the point of run-off. Higher 
volumes are necessary where the brush is very dense and 0\ >r 6 to 8 feet high. Appli­
cations are more effective when applied to actively growing plants. DO NOT treat 
during periods of severe drought or in early fall when leaves have lost their healthy 
green color. Hard-to-kill species may need retreatment the fol lowing season. 
GENERAL WEED CONTROL: Along fence rows, ditchbanks, around farm buildings and similar//­
areas, use 1 1/3 to 2 2/3 pints of RIVERSIDE 2,4-0 BUTYL ESTER 6 in 100 gallons of ~ 
water per acre. Tholoughly wet al I fol iage to run-off.
