ENVl:RONIIENTAL HAZARDS
This product is toxic to aquatic invertebrates. Drift or runoff may adversely affect
aquatic invertebrates 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
mark. Vapors from the 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, okra, 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 spray drift. Do not apply with hollow cone type insecti.:i::e or
other nozzles that produce fine spray droplets. Spray drift can be lessened JI keeping
the spray boom as low as possible, by spraying when wind velocity is low, by j'2!:::reasing
the pounds of pressure of the nozzle tips, and by stopping all spraying when ·~nc
exceeds 6 to 7 miles per hour. On cropland and along roadsides, do ~~t exceed 20 psi
pressure. Do not apply when a temperature air inversion exists. I~ questio~s exist
pertaining to the existence of an inversion, consult with local wea~~?r serv~ces before
making an application. Do not use the same spray equipment for applY~~4 other •••
materials to 2,4-0 susceptible crops as injury may result. It is b~.st...to use. a. •.
separate sprayer for application of insecticides and fungicides. Cl~~and rinse spray
equipment using soap or detergent and water or suitable chemical cleaner, and ~i.nse
thoroughly before reuse for other spraying. Do not contaminate water when dis?0Sing of
equipment washwaters. Do not apply this product through any type of irrigation system.
Do not contaminate domestic or irrigation water.
Riverdale 638 Broadleaf Herbicide Page
However, treated water may be used for watering turf grasses immediately after
application. Do not use in or near a greenhouse. 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 2,4-0 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.

GENBRAL XNFORMATXON
.
Riverdale 338 Broad1eaf Herbicide is a special formulation containing 2.4-0 acid.
Riverdale 33-8 is mO'ce effective than 2.4-0 amines for controlling hard-to-kill weeds such
as field bL1dweed. ;<..ls&ian knapweed, Canada thistle, leafy spurge. cattails, tules and
nutgrass.
Riverdale· 638 Broadleaf Herbicide should be applied when daytime temperatures are lower
than 80 to 85 degrees. Spraying when temperatures are higher may cause rapid foliar burn
and decrease the effectiveness of Riverdale 638. Treatment at higher temperatures also
increases the possibility of crop injury.

INJURY TO CROPS FROM THIS HERBICIDE MAY OCCUR.
DEGREE OF CROP INJURY, DO NOT USE THIS PRODUCT.
IF YOU ARE NOT PREPARED TO ACCEPT SOME
Crop varieties vary in response to 2,4-D and some are easily injured. Apply Riverdale 638
only to varieties known to be tolerant to 2,4-D. If you are uncertain concerning tolerant
varieties or local use situations that may affect crop tolerance to 2,4-D, consult your
seed company or State Agricultural Extension Service for advice.
MIXING INSTRUCTIONS
Add one-half the required amount of water to the spray tank, then add the Riverdale 638
with agitation, and finally, the balance of the water with continued agitation. Provide
continuous agitation to insure uniform spray mixtures. Use spray mixture as soon as
possible after mixing.
COMPATIBILITY
If Riverdale 638 is to be tank mixed with fertilizers or with other pesticides,
compatibility should be tested prior to mixing. To test for compatibility, use a small
container and mix a small amount (0.5 to 1 quart) of spray, combining all ingredients in
the same ratio as the anticipated use. If any indications of physical incompatibility
develop, do not use this mixture for spraying. Indications of incompatibility usually
will appear within 5 to 15 minutes after mixing. Read and follow the label of each tank­
mix product used for precautionary statements, directions for use, geographic and other
restrictions.
COMBINATION WITB LIQUID NITROGEN FERTILIZER
Use the recommended amount of Riverdale 638 Broadleaf Herbicide per acre for weeding and
feeding corn, small grains, grasses for production or grass pastures as directed on this
label. Use the fertilizer at rates recommended by supplier or Extension Service
Specialist. Fill the spray tank about half full with the liquid fertilizer, then add the
Riverdale 638 with vigorous agitation, and complete filling the tank. Apply immediately
and continue agitation in the spray tank during application. Do not allow mixture to
stand overnight. NOTE: Fertilizers can increase foliage contact burn of herbicides.
Reducing the fertilizer rate and concentration will reduce the hazard of leaf burn.

DIRECTIONS
Apply after grain is fully tillered
(usually about 4 to 8 inches high) but
not forming joints in the stern. Apply
when weeds are near bud stage. Do not
spray grain in boot to dough stage.
Apply 20.5 ounces when grain is fully
tillered and wild garlic or onion plants
are small. Apply 27.4 ounces after
harvest in the crop stubble. For control
of new fall growth of wild onion or
garlic, refer to FALLOW LAND use
directions.
Apply when weeds are approaching bud
stage, but do not spray grain during the
boot to dough stage. The 41.0 ounces per
acre application can produce injury to
wheat. Balance the severity of your weed
problem against the possibility of crop
damage. Where perennial weeds are
scattered, spot treatment is suggested to
minimize the extent of crop injury.
~----- .. -----------+-----------~------------------~~~----~ Preharves:: 13.6 ounces

Apply when grains are in the hard dough
stage to suppress large weeds that may
interfere with harvest. Best results
will be obtained when soil moisture is
sufficient to induce succulent weed
growth.
DO NOT USE IN CALIFORNIA.
*Use the luwer rate if small annual and biennial weeds are the major problem. Use the
higher rat~' If perennial weeds or annual and biennial weeds are present which are in the
hard-to-k~ll ~ategories as determined by local experience. The higher rates increase the
risk of g:L:<..J.i..l injury and should be used only wher~ weed control problems justify the risk
of grain damage. Do not apply to grain in the seedling stage.
