Label Notification per PR N 07-04 & 98-10
Dear Ms. Montague
Nufarm Americas Inc. would like to add language and modify language to the label for
Formula 40 (EPA Reg. No. 228-357) registration. Per PR Notice 2007-04 we have
updated the Storage and Disposal of this label. Per PR Notice 1988-10 we have added
text to allow for multiple container sizes and configurations. Additionally per PR Notice
1998-10 we have corrected the Maximum Use Rate for Strawberries - this use rate was
correctly found at 1-1/2 quarts per acre on page 5 of the table, but later in the label this
rate incorrectly was stated to be 1-1/2 pints per acre.
Since this submission is being undertaken a non-PRIA guided action no payment has
been rendered for this review.
To process this request please find enclosed the following:
• Application for Pesticide Registration EPA form 8570-1
• Label Certification Statement
• Revised labeling - highlighted (1 copy)
• Revised labeling - clean (1 copy)
• CD with Clean version of the Revised, Proposed Label

GENERAL INFORMATION
Formula 40° Herbicide is intended for selective control of many broadleaf weeds in non-crop areas, grass pastures, rangelands
and in certain crops. It may also be applied by injection to control trees.
Use of this product in certain portions of California, Oregon, and Washington is subject to the January 22, 2004 Order for injunctive
relief in Washington Toxics Coalition, et. al. v. EP. C01 -01 32C, (W.D. WA). For further information, please refer to
http://www.epa.aov/espp/.
USE PRECAUTIONS
Avoid contact with 2,4-D susceptible crops and other desirable broadleaf plants: Do not apply directly to or otherwise permit
even minute amounts to contact cotton, grapes, tobacco, fruit trees, vegetables, flowers, ornamentals or other desirable plants
susceptible to 2,4-D.
Do not use in or near a greenhouse.
Be sure that use of this product conforms to all application regulations.
Chemigation: Do not apply this product through any type of irrigation system.
Crop Injury: Injury to crops may occur when this herbicide is used as approved elsewhere on this label. If you are not prepared to
accept some degree of crop injury, do not use this product Crop varieties vary in response to 2,4-D and some are easily injwad.^iSb.iy
Formula 40 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, state agricultural extension service or qualified crop consu^tantcfor
advice. £ c c t c
SPRAY DRIFT MANAGEMENT _f ' c
A variety of factors including weather conditions (e.g., wind direction, wind speed, temperature, relative fjumiBify,; and methodrof
application (e.g., ground, aerial, airblast, chemigation) can influence pesticide drift. The applicator must evaluate all factors anr1 cTtal-c
appropriate adjustments when applying this product. c. t c i- c c <-
c c *- *"
Droplet Size (tt<i < ^ <-<.<-
When applying sprays that contain 2,4-D as the sole active ingredient, or when applying sprays that contain 2/-D niixed with active
ingredients that require a Coarse or coarser spray, apply only as a Coarse or coarser spray (ASAE standardc57k)'or a volume mean
diameter of 385 microns or greater for spinning atomizer nozzles. i c t. c t r.
When applying sprays that contain 2,4-D mixed with other active ingredients that require a Medium or more fine spray, apply only a^s
a Medium or coarser spray (ASAE standard 572) or a volume mean diameter of 300 microns or greater for spinning atomizer rfoz^les'.c.

r r 7 IS
Wind Speed
Do not apply at wind speeds greater than 15 mph. Only apply this product if the wind direction favors on-target deposition and there
are not sensitive areas (including, but not limited to, residential areas, bodies of water, known habitat for nontarget species, nontarget
crops) within 250 feet downwind. If applying a Medium spray, leave one swath unsprayed at the downwind edge of the treated field.
Temperature Inversions
If applying at wind speeds less than 3 mph, the applicator must determine if: a) conditions of temperature inversion exist, or b) stable
atmospheric conditions exist at or below nozzle height. Do not make applications into areas of temperature inversions or stable
atmospheric conditions.
Susceptible Plants
Do not apply under circumstances where spray drift may occur to food, forage, or other plantings that might be damaged or crops
thereof rendered unfit for sale, use or consumption. Susceptible crops include, but are not limited to, cotton, okra, flowers, grapes (in
growing stage), fruit trees (foliage), soybeans (vegetative stage), ornamentals, sunflowers, tomatoes, beans, and other vegetables, or
tobacco. Small amounts of spray drift that might not be visible may injure susceptible broadleaf plants.
Other State and Local Requirements
Applicators must follow all state and local pesticide drift requirements regarding application of 2,4-D herbicides. Where states have
more stringent regulations, they must be observed.
Equipment
All aerial and ground application equipment must be properly maintained and calibrated using appropriate carriers or surrogates.
Aerial Equipment
The boom length must not exceed 75% of the wingspan or 90% of the rotor blade diameter.
Release spray at the lowest height consistent with efficacy and flight safety. Do not release spray at a height greater than 10 feet
above the crop canopy unless a greater height is required for aircraft safety. This requirement does not apply to forestry
or rights-of-way applications.
When applications are made with a crosswind, the swath will be displaced downwind. The applicator must compensate for this by
adjusting the path of the aircraft upwind.
Ground Equipment
Do not apply with a nozzle height greater than 4 feet above the crop canopy.
Excessive amounts of this herbicide in the soil may temporarily inhibit seed germination or plant growth. Violent wind storms may
move soil particles. If 2,4-D is on soil particles and they are blown onto the susceptible plants, visible symptoms may appear. Serious
injury is unlikely. The hazard of movement of 2,4-D on dust is reduced if treated fields are irrigated or if rain occurs shortly after
application.
To avoid injury to desirable plants, do not handle or apply other agricultural chemicals with the same equipment used for Formula 40
unless appropriately cleaned first. Local conditions may affect the use of herbicides. Consult your State Agricultural Experiment
Station or Extension Service weed specialists for cleaning methods which are in compliance with local regulations and for advice in
selecting treatments from this label to best fit local conditions. Be sure that use of this product conforms to all applicable regulations.
WEEDS CONTROLLED
Formula 40 Herbicide is recommended for control of numerous broadleaf weeds and certain 2,4-D susceptible woody perennials
without injuring most grasses. Species controlled include the following plus many others:
Bitterweed Jewelweed Plantains Sunflower
Broomweed Jimsonweed Poorjoe Sweetclover
Burdock Lambsquarter Florida pusley Bull thistle
Carpetweed Loco Bigbend Common ragweed Musk thistle
Chicory Lupine Wild rape Russian thistle
Cocklebur Venice mallow Yellow rocket, Velvetleaf

Dandelion Pennycress (Fanweed) Annual smartweed Wild mustard
Dock Pennywort Bitter sneezeweed Witchweed
Galinsoga Field pepperweed Annual sowthistle Wormwood , <.
Wild hemp Pigweedf Spanishneedle j. <. i <. < <•
fThe control of "hybrid" Pigweeds appears to be less satisfactory from 2,4-D products than formerly experienced on "nori-hybrir?"
varieties. Since 2,4-D herbicides are not as effective on the "hybrid" Pigweeds, it is necessary to apply higher rates of 2,4-D ftr col ilvol,
especially later in the growing season. Higher rates injure some crops, so less than satisfactory pigweed contrpj rn-a« be experienced
by the highest tolerated crop dosages. I ~~ ~~ <- ^ c ,,
Therefore, Nufarm no longer includes Pigweed among the species covered by the performance guarantee statenierits on tbe labels
for Formula 40. At this time, this disclaimer applies only to the High Plains of Texas and western O&lr'horr-a, including the
Panhandles. All other guarantees on these product labels are unchanged by this disclaimer. L'' i <. <- <- < <•
(. I O L 1 l
Generally, the lower dosages given will be satisfactory for young, succulent growth of sensitive weed species. Fur less sensitive
species and under conditions where control is more difficult, the higher dosages will be needed. Apply Formula 40 during warrn
weather when weeds are young and growing actively. Use enough spray volume for uniform coverage by ground or air applic£'br./-l'
only bands or rows are treated, leaving middles unsprayed, the dosage per crop acre is reduced proportionately. Do not appiy where
spray drift may be a problem due to proximity of susceptible crops or other desirable plants. Read and follow all Use Pret,£Jtiofisv
given on this label. 1. < i.

TO PREPARE THE SPRAY
Mix Formula 40 only with water, unless otherwise directed on this label. Add about half the water to the mixing tank, then add the
Formula 40 with agitation, and finally the rest of the water with continuing agitation. Note: Adding oil, wetting agent or other surfactant
to the spray may increase effectiveness on weeds, but also may reduce selectivity to crops resulting in crop damage.
USE WITH LIQUID FERTILIZER
Formula 40 may be combined with liquid fertilizers suitable for foliar application to accomplish weeding and feeding of corn, small
grains, sorghum and grass pastures in one operation. Use Formula 40 in accordance with recommendations for these crops given in
the following text and table. Use liquid fertilizer at rates recommended by supplier or local extension service specialist. To prepare the
spray, Formula 40 must first be premixed with water. For liquid nitrogen fertilizer use a premix consisting of 1 part of Formula 40 and
4 parts of water; for other liquid fertilizers use 1 part of Formula 40 with 50 to 60 parts of water. Add the premix to the fertilizer while
maintaining continuous agitation during both mixing and spraying operations. Apply the spray the same day it is prepared; do not store.
Note: Always premix Formula 40 with water before adding to the liquid fertilizer.

WEED CONTROL IN ASPARAGUS
See table for recommended use rates. To control Wild Morningglory and certain other broadleaf weeds apply in about 60 gallons of
water per acre for ground application and about 12 gallons per acre for aircraft application. Apply on actively growing weeds, usually
in April or May. If spears are present, treat immediately after cutting. Make no more than 2 applications during the harvest season and
these should be spaced at least one month apart. Spears contacted by the spray may be malformed and off-flavored. Malformed
spears should be cut immediately and discarded. Post-harvest spraying should be only by ground rig using drop nozzles to avoid
spraying the fern.
USE PRECAUTIONS FOR ASPARAGUS
The preharvest interval (PHI) is 3 days. Limited to 2 applications per crop cycle.
Maximum of 2 quarts of product/acre per application.
Minimum of 30 days between applications.
WEED CONTROL IN SMALL GRAINS NOT UNDERSEEDED WITH A LEGUME (wheat, Barley, Rye, Oats, Millet)
See table for recommended use rates. Spray after grain begins tillering and before the boot stage (usually 4 to 8 inches tall) and weeds
are small. Do not apply before the tiller stage nor from early boot through the milk stage. To control weeds that will interfere
with harvest or to suppress perennial weeds, preharvest treatment can be applied when the grain is in the dough stage. Best results
will be obtained when soil moisture is adequate for plant growth and weeds are growing well. Note: Do not permit dairy animals or
meat animals being finished for slaughter to forage or graze treated grain fields within 2 weeks after treatment.
USE PRECAUTIONS FOR CEREAL GRAINS (wheat, Barley, Rye, Oats, and Millet)
The preharvest interval (PHI) is 14 days.
Postemergence:
Limited to one postemergence application per crop cycle.
Maximum of 1.56 pints of product /acre per application.
Preharvest:
Limited to one preharvest application per crop cycle.
Maximum of 1 pint of product/acre per application.
Limited to 3.25 pints of product/acre per crop cycle.
WEED CONTROL IN CORN
See table for recommended use rates.
Preemergence: Apply to soil anytime after planting but before corn emerges. Only emerged broadleaf weeds are likely to be
controlled. Do not use on very light, sandy soil.
Emergence: Apply just as corn plants are breaking ground.
Postemergence: Apply to emerged corn. When corn is over 8 inches tall use drop nozzles to keep spray off corn foliage. Do not apply
from tasseling to dough stage. Injury to corn is most likely to occur if Formula 40 is applied when corn is growing rapidly under high
temperature and high soil moisture conditions. In such situations, use the low rate of 1/2 pint per acre. After application, delay
cultivation for 8 to 10 days to allow the corn to overcome any temporary brittleness. Note: Hybrids vary in tolerance to 2,4-D. Some
are easily injured, especially sweet corn. Spray only varieties known to be tolerant to 2,4-D. Consult the seed company or your
Agricultural Experiment Station or Extension Service Weed Specialist for this information before using.
Preharvest: After the hard dough or denting stage, apply by air or ground equipment to suppress perennial weeds, decrease weed
seed production, and control tall weeds such as Bindweed, Cocklebur, Dogbane, Jimsonweed, Ragweed, Sunflower, Velvetleaf, and
vines that interfere with harvesting. Note: Do not forage or feed corn fodder for 7 days following application.
USE PRECAUTIONS FOR CORN (Field and Pop)
Do not use treated crop as fodder for 7 days following application.
The preharvest interval (PHI) is 7 days.
Maximum of 6.5 pints of product/acre per crop cycle.
Preplant or Preemergence
Limited to one preplant or preemergence application per crop cycle.
Maximum of 2.15 pints of product /acre per application. \. t < c c < t
Postemergence

WEED CONTROL IN SORGHUM (MILO)
See table for recommended use rates. Treat only after the sorghum is 6 inches high and preferably before it is 15 inches high. Do not
treat during the boot, tasseling or early dough stages. Reduce spray drift by keeping the boom and spray nozzles as low as possible.
If crop is taller than 8 inches, use drop nozzles to keep the spray off the leaves. Temporary crop injury can be expected under
conditions of high soil moisture and high air temperatures. If it is necessary to apply Formula 40 under these conditions, use no more
than 2/3 pint per acre. Note: Hybrids vary in tolerance to 2,4-D. Some are easily injured. Spray only varieties known to be tolerant to
2,4-D. Consult the seed company or your Agricultural Experiment Station or Extension Service Weed Specialist for this information.

For rangeland or pasture, the maximum application rate is 2 quarts per acre per application. On roadsides and fence rows use 1
gallon of Formula 40 plus 4 to 8 fluid ounces of an agricultural surfactant per 100 gallons of water and spray thoroughly as soon as
foliage is well-developed. Two or more treatments may be required. Apply at a maximum rate of 4 quarts per acre per application as
a spot treatment.
Grazing Restrictions: Do not graze lactating dairy animals on treated areas within 7 days after application. Do not harvest grass
cut for hay from treated areas for 30 days. Withdraw meat animals from treated forage at least 3 days before slaughter.
Spot Treatment in Non-Crop Areas
To control broadleaf weeds in small areas with a hand sprayer, use 1/4 pint (4 oz.) of Formula 40 in 3 gallons of water and spray to
thoroughly wet all foliage.
Tree Injection Treatment
To control unwanted hardwood trees such as Elm, Hickory, Oaks, and Sweetgum in forests and non-crop areas, apply Formula 40*
by injecting 1 ml of the undiluted product through the bark around the trunk at intervals of 1 to 3 inches between edges of the injector
wounds. For harder to control species such as Ash, Maples and Dogwood use 2 ml of undiluted Formula 40 per injection site.
Continuous cuts around the trunk often provide improved control. Also, cuts near the ground level may be more effective than at higher
levels. Treatments can be made at any season; however, effectiveness may be less during winter months. Maples should not be
treated during the spring sap flow. Limited to one injection application per year.
Note: No worker Protection Standard worker entry restrictions or worker notification requirements apply when this
product is directly injected into agricultural plants.
TURF USES
Use Requirements for Turf Including Sod Farms and Turfgrass Grown for Seed
Restricted Entry Interval: When used on sod farms or turf grown for seed, follow PPE and reentry instructions in the
"Agricultural Use Requirements" section of this label. For use on other turf areas, do not allow people (other than applicator) or
pets on treatment area during application. Do not enter into treated areas until sprays have dried.
Restrictions on Treatment: Do not apply more than 2 broadcast applications per year per treatment site.
WEED CONTROL IN SOD FARMS
Use 1 to 3 quarts of Formula 40 per acre in the amount of water needed for uniform application. Treat when weeds are young and
growing well. Usually 2 quarts per acre will provide adequate weed control. Do not use on dichondra or other herbaceous ground covers.
Do not use on creeping grasses such as Bent except for spot treating nor on freshly seeded turf until grass is well established.
Reseeding should be delayed following treatment. With spring application, reseed in the fall; with fall application, reseed in the spring.
Legumes are usually damaged or killed. Deep-rooted perennial weeds such as Bindweed and Canada thistle may require repeated
applications.
WEED CONTROL IN TURFGRASS GROWN FOR SEED
Use 1 to 4 pints per acre in spring or fall. Do not apply from early boot to the milk stage of the grass. Spray seedling grass only after
the five-leaf stage, using 3/4 to 1 pint per acre to control small seedling weeds. After the grass is well established, higher rates, up to
4 pints, can be used to control hard-to-kill annual or perennial weeds. Do not use on Bentgrass unless grass injury can be tolerated.
