MIXING, ADDITIVES AND APPLICATION INSTRUCTIONS 
APPLY THESE SPRAY SOLUTIONS IN PROPERL Y MAINTAINED AND 
CALIBRATE EQUIPMENT CAPABLE OF DELIVERING DESIRED VOLUMES. DO 
NOT APPLY UNDER WIND OR OTHER CONDITIONS THAT ALLOW DRIFT TO 
OCCUR. HAND GUN APPLICATIONS SHOULD BE PROPERLY DIRECTED TO 
AVOID SPRAYING DESIRABLE PLANTS. NOTE: REDUCED RESULTS MAY 
OCCUR IF WATER CONTAINING SOIL IS USED, such as WATER FROM PONDS 
AND UNLINED DITCHES. 
MIXING .. 
This product mixes readily with water. Mix spray solutions of this product as follows: 
Fill the mixing or spray tank with the required amount of water. Add the proper amount 
of this product (see "Directions for Use'" and "Weeds Controlled" sections of this label) 
near the end of the filling process and mix well. Remove hose from tank immediately 
after filling to avoid siphoning back into the carrier source. During mixing and 
application foaming of the spray solution may occur. To prevent or minimize foam, avoid 
the use of mechanical agitators, place the filling hose below the surface of the spray 
solution, terminate by-pass and return lines at the bottom of the tank and if needed use an 
approved anti-foam or defoaming agent. 
Roundup Rainfast EPA Reg. No. 524-445 Page 70f40

Version: 13-Jnne-2005 
TANK MIXTURES 
Always predetermine the compatibility oflabeled tank mixtures of this herbicide with 
water carrier by mixing small proportional quantities in advance. 
Mix labeled tank mixtures of this product with water as follows: 
1. Place a 20 to 35 mesh screen or wetting basket over filling port. 
2. Through the screen, fill the sprayer tank one-half full with water and start 
agitation. 
3. If a wettable powder is used, make a slurry with the water carrier, and add it 
SLOWLY through the screen into the tank. Continue agitation. 
4. If a flowable formulation is used, premix one part flowable with one part water. 
Add diluted mixture SLOWLY through the screen into the tank. Continue 
agitation. 
5. If an emulsifiable concentrate formulation is used, premix one part emulsifiable 
concentrate with two parts water. Add diluted mixture slowly through the screen 
into the tank. Continue agitation. 
6. Continue filling the sprayer tank with water and add the required amount of this 
product near the end of the filling. 
7. Add individual formulations to the spray tank as follows: wettable powder, 
flowable, emulsifiable concentrate, drift control additive, water-soluble liquid 
followed by surfactant. 
Maintain good agitation at all times until the contents of the tank are sprayed. If the spray 
mixture is allowed to settle, thorough agitation is required to resuspend the mixture 
before spraying is resumed. 
Keep by-pass line on or near bottom of tank to minimize foaming. Screen size in nozzle 
or line strainers should be no finer than 50 mesh. Carefully select proper nozzle to avoid 
spraying a fine mist. For best results with conventional ground application equipment, 
use flat fan nozzles. 
Clean sprayer and parts immediately after using this product by thoroughly flushing with 
water. 
ADDITIVES 
SURFACTANTS 
Nonionic surfactants that are labeled for use with herbicides may be used. Do not reduce 
rates of this herbicide when adding surfactant. When adding additional surfactant, use 0.5 
percent surfactant concentration (2'quarts per 100 gallons of spray solution) when using 
surfactants that contain at least 50 percent active ingredient, or a 1 percent surfactant 
concentration (4 quarts per 100 gallons of spray solution) for those surfactants containing 
less than 50 percent active ingredient. Read and carefully observe surfactant cautionary 
statements and other information appearing on the surfactant label. 
AMMONIUM SULFATE 
The addition of2 percent dry ammonium sulfate by weight or 17 pounds per 100 gallons 
of water may increase the performance of this product on annual and perennial weeds. 
The improvement, in performance may be apparent where environmental stress is a 
concern. Low-quality-ammonium sulfate may contain material that will not readily 
Roundup Rainfas! EPA Reg. No. 524-445 Page 8 of 40

Version: 13-June-2005 
dissolve which could result in nozzle tip plugging. To determine quality, perform a jar 
test by adding 11 cup of ammonium sulfate to -I gallon of water and agitate for I minute. 
Ifundissolved sediment is observed, predissolve the ammonium sulfate in water-and 
filter prior to addition to the spray tank. If Ammonium sulfate is added directly to the 
spray tank, add slowly with agitation. Adding too quickly may clog outlet lines. Ensure 
that ammonium sulfate is completely dissolved in the spray tank before adding herbicides 
or surfactant. Thoroughly rinse the spray system with clean water after use to reduce 
corroSIOn. 
NOTE: The use of ammonium sulfate as an additive does not preclude the need for 
additional surfactant. Do not use herbicide rates lower than recommended in this label. 
COLORANTS OR DYES 
Agriculturally approved colorants or marking dyes may be added to this product. 
Colorants or dyes used in spray solutions of this product may reduce performance, 
especially at lower rates or dilutions. lIse colorants or dyes according to the 
manufacturer's recommendations.

Version: 13-Jooe-2005 
AERIAL SPRAY DRIFT MANAGEMENT 
The following drift management requirements must be followed to avoid off-target drift 
movement from aerial applications to agricultural field crops. 
1. The distance of the outermost nozzles on the boom must not exceed 3/4 the length of 
the wingspan or rotor. 
2. Nozzles must always point backward, parallel with the air stream and never be 
pointed downwards more than 45 degrees. Where states have more stringent 
regulations, they should be observed. 
Importance of droplet size 
The most effective way to reduce drift potential is to apply large droplets. The best drift 
management strategy is to apply the largest droplets that provide sufficient coverage and 
control. Applying larger droplets reduces drift potential, but will not prevent drift if 
applications are made improperly, or under unfavorable environmental conditions (see 
the Wind, Temperature and Humidity, and Temperature Inversions sections of this 
label). 
Controlling droplet size 
• Volume: Use high flow rate nozzles to apply the highest practical spray volume. 
Nozzles with the higher rated flows produce larger droplets. 
• Pressure: Use the lower spray pressures recommended for the nozzle. Higher 
pressure reduces droplet size and does not improve canopy penetration. When higher 
flow rates are needed, use higher flow rate nozzles instead of increasing pressure. 
• Number of nozzles: Use the minimum number of nozzles that provide uniform 
coverage. 
• Nozzle orientation: Orienting nozzles so that the spray is released backwards, 
parallel to the airstream, will produce larger droplets than other orientations. 
Significant deflection from the horizontal will reduce droplet size and increase drift 
potential. 
• Nozzle type: Use a nozzle type that is designed for the intended application. With 
most nozzle types, narrower spray angles produce larger droplets. Consider using 
low-drift nozzles. Solid stream nozzles oriented straight back produce larger droplets 
than other nozzle types. 
• Boom Length: For some use patterns, reducing the effective boom length to less 
than 3/4 of the wingspan or rotor length may further reduce drift without reducing 
swath width. 
• Application Height: Applications should not be made at a height greater than 10 
feet above the top of the largest plants unless a greater height is required for aircraft 
safety. Making applications at the lowest height that is safe reduces the exposure of 
the droplets to evaporation and wind. 
Swath Adjustment 
When applications are made with a crosswind, the swath will be displaced downward. 
Therefore, on the up and downwind egges of the field, the applicator must compensate 
for this displacement by adjusting the path of the aircraft upwind. Swath adjustment 
Roundup Rainfast EPA Reg. No. 524-445 Page 10 0[40

Version: \3-June-2005 
distance should increase, with increasing drift potential (higher wind, smaller droplets, 
etc.). 
Wind 
Drift potential is lowest between wind speeds of2 to 10 mph. However, many factors, 
including droplet size and equipment type determine drift potential at any given speed. 
Application should be avoided below 2 mph due to variable wind direction and high 
inversion potential. NOTE: Local terrain can influence wind patterns. Every applicator 
should be familiar with local wind patterns and how they affect drift. 
Temperature and Humidity 
When making applications in low relative humidity, set up equipment to produce larger 
droplets to compensate for evaporation. Droplet evaporation is most severe when 
conditions are both hot and dry. 
Temperature Inversions 
Applications should not occur during a temperature inversion because drift potential is 
high. Temperature inversions restrict vertical air mixing, which causes small suspended 
droplets to remain in a concentrated cloud. This cloud can move in unpredictable 
directions due to the light variable winds common during inversions. Temperature 
inversions are characterized by increasing temperatures with altitude and are common on 
nights with limited cloud cover and light to no wind. They begin to form as the sun sets 
and often continue into the morning. Their presence can be indicated by ground fog; 
however, if fog is not present, inversions can also be identified by the movement of 
smoke from a ground source or an aircraft smoke generator. Smoke that layers and moves 
laterally in a concentrated cloud (under low wind conditions) indicates an inversion, 
while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. 
Sensitive areas 
The product should only be applied when the potential for drift to adjacent sensitive areas 
(e.g. residential areas, bodies of water, known habitat for threatened or endangered 
species, non-target crops) is minimal (e.g. when wind is blowing away from the sensitive 
areas). 
Avoid direct application to any body of water. 
Aircraft Maintenance 
Thoroughly wash aircraft, especially landing gear, after each day of spraying to remove 
residues of this product accumulated during spraying or from spills. PROLONGED 
EXPOSURE OF THlS PRODUCT TO UNCOATED STEEL SURFACES MAY 
RESULT IN CORROSION AND POSSIDLE FAILURE OF THE PART. LANDING 
GEAR IS MOST SUSCEPTIDLE. The maintenance of an organic coating (paint), which 
meets aerospace specification MIL-C-38413, may prevent corrosion. 
BROADCAST EQUIPMENT 
For control of annual or perennial weeds listed on this label using broadcast 
equipment- Use the recommended rates of this product in 3 to 40 gallons of water per 
acre as a broadcast spray unless otherwise specified on this label. See the "Weeds 
Controlled" section of this label for specific rates. As density -of weeds increases, spray 
gallonage should be increased within the recommended range to ensure complete 
coverage. Carefully select proper nozzle to avoid spraying a fine mist. For best results 
Roundup Rainfa,! EPA Reg. No. 524-445 Page 11 01'40

Version: 13-Jooe-2005 
with ground application equipment, use flat fan nozzles. Check for even distribution of 
spray droplets. 
CONTROLLED DROPLET APPLICATION (CDA) 
The rate of this product applied per acre by vehicle-mounted CDA equipment must not 
be less than the amount recommended in this label when applied by conventional 
broadcast equipment. For vehicle-mounted CDA equipment apply 3 to 20 gallons of 
water per acre. 
For the control oflabeled annual weeds with hand-held CDA units, apply a 36 percent 
solution of this product at a flow rate of3.5 fluid ounces per minute and a walking speed 
of 1.5 MPH (56 ounces per acre). For the control oflabeled perennial weeds, apply a 36 
to 72 percent solution of this product at a flow rate of3.5 fluid ounces per minute and a 
walking speed of 0.75 MPH (3.5 t07 quarts per acre). 
Controlled droplet application equipment produces a spray pattern, which is not easily 
visible. Extreme care must be exercised to avoid spray or drift contacting the foliage or 
any other green tissue of desirable vegetation as damage or destruction may result. 
HAND-HELD and HIGH-VOLUME EQUIPMENT 
Use coarse sprays only. 
Mix this product in clean water and apply to foliage of vegetation to be controlled. For 
applications made on a spray-to-wet basis, spray coverage should be uniform and 
complete. Do not spray to the point of runoff. 
For control of annual weeds listed on this label, apply a I percent solution of this product 
to weeds less than 6 inches in height or runner length. Apply prior to seedhead formation 
in grass or bud formation in broadleaves. Allow three or more days before tillage or 
mowmg. 
For annual weeds over 6 inches tall, or when not using additional surfactant, or unless 
otherwise specified, use a 2 percent solution. For best results, use a 3.5 percent solution 
on harder-to-control perennials, such as Bermudagrass, dock-, field bindweed, hemp 
doqbane, milkweed, Canada thistle and torpedograss. 
Less than complete coverage of weeds may result from the use of spray equipment 
designed for motorized spot treatments. Where less than complete coverage of annual 
weeds occurs, use a 9 percent solution. Do not reduce recommended concentrations of 
this product when adding surfactant. 
Prepare the desired volume of spray solution by mixing the amount of this product in 
water as shown in the following table:

For hand-held WIPER APPLICATORS see the "Selective Equipment" section and for 
hand-held CONTROLLED DROPLET APPLICATORS see the "Controlled Droplet 
Applicator (CDA)'~·section of this label. 
SELECTIVE EQUIPMENT 
This product may be applied through a shielded applicator or a wiper applicator after 
dilution and thorough mixing with water to listed weeds growing in any non-crop site 
specified on this label and only when specifically recommended in cropping systems. 
A shielded applicator directs the herbicide solution onto weeds while shielding desirable 
vegetation from the herbicide. 
A wiper applicator applies the herbicide solution onto weeds by rubbing the weed with an 
absorbent material containing the herbicide solution. 
AVOID CONTACT WITH DESIRABLE VEGETATION - Contact of the herbicide 
solution with the desirable vegetation may result-in damage or destruction. Applicators 
used above desired vegetation should be adjusted so that the lowest wiper contact point 
is at least two inches above the desirable vegetation. Droplets, mist, foam or splatter of 
the herbicide solution settling on desirable vegetation may result in discoloration, 
stunting or destruction. 
Applications made above the crops should be made when the weeds are a minimum of6 
inches above the desirable vegetation. Better results may be obtained when more of the 
weed is exposed to the herbicide solution. Weeds not contacted by the herbicide solution 
will not be affected. This may occur in dense clumps, severe infestations, or when the 
height of the weeds varies so that not all weeds are contacted. In these instances, repeat 
treatment may be necessary. 
See the "Weeds Controlled" section of this label for recommended stage of growth for 
specific weeds. 
NOTE: 
• Maintain equipment in good operating condition. Avoid leakage or dripping onto 
desirable vegetation. 
• Adjust height of applicator to insure adequate contact with weeds. 
• Keep nozzle tips and wiping surfaces clean. 
• Keep shields on shielded applicators adjusted to protect desirable vegetation. 
• Maintain recommended rolter RPM on roller applicators while in use. 
• Keep wiper material at proper degree of saturation with herbicide solution. 
• Equipment speed affects wiper deposition. For best results operate equipment at 
less than 5 mph. As weed density increases, reduce equipment ground speed to 
ensure good coverage. 
• Be aware that on sloping ground the herbicide solution may migrate, causing 
dripping on the lower end and drying on the upper end of a wiper applicator. 
Roundup Rainfast EPA Reg. No. 524-445 Page 130[40

Version: 13-June-2005 
• Variation ih equipment design may affect weed control. With wiper applicators, 
the wiping material and its orientation must allow delivery of sufficient quantities 
of the recommended herbicide solution directly to the weed. 
• Care must be taken with all types of wipers to ensure that the absorbent material 
does not become over-saturated, causing the herbicide to drip on desirable 
vegetation. 
• Drain and clean sprayer and wiper parts immediately after using this product by 
thoroughly flushing with water. 
SHIELDED APPLICATORS 
When applied as directed under conditions described for shielded applicators, this 
product will control those weeds listed in the "Weeds Controlled" section of this label. 
Shielded applicators that may apply the herbicide solution as a spray band should be 
calibrated on a broadcast equivalent rate and volume basis. To determine these:

For specific rates of application and instructions for control of various annual and 
perennial weeds, see the "Weeds Controlled" section of this label. 
WIPER APPLICA TORS 
Wiper applicators include either roller or wick devices that physically wipe appropriate 
concentrations or amounts of this product directly onto the weed. Equipment must be 
designed, maintained, and operated to prevent the herbicide solution from 'contacting 
desirable vegetation. Performance may be improved by reducing speed in areas of heavy­
weed infestations to ensure adequate wiper saturation. Better results may be obtained if 
two applications are made in oppoSite directions. 
For Roller Applicators- Mix an 18 percent solution of this product. Apply this solution 
to perennial weeds or annual broadleafweeds listed in the "Weeds Controlled" and 
"Wiper Applications" sections. 
Mix a 5-percent solution of this product. Apply this solution to annual grasses listed in 
the "Weeds Controlled" and "Wiper Applications" sections. 
Roller speed should be maintained at 40 to 60 RPM. 
For Wick or Wiper Applicators - Mix a 60 percent solution of this product. Apply this 
solution to weeds listed in the "Weeds Controlled" and "Wiper Applications" Sections. 
ROWldup Rainfast EPA Reg. No. 524-445 Page 14 of40

Version: 13-June-2005 
In severe infestations, reduce equipment ground speed to ensure that adequate amounts of 
this product are wiped on the weeds. A second treatment in the opposite direction may be 
beneficial. 
Do not permit herbicide solution to contact desirable vegetation 
WEEDS CONTROLLED 
This herbicide controls many annual and perennial grasses and broadleafweeds. 
ANNUAL WEEDS 
• For best results apply to actively growing grass and broadleafweeds. 
• To prevent seed production, applications should be made prior to seedhead 
formation. 
• This product does not provide residual control; therefore, delay application until 
maximum weed emergence. Repeat treatments may be necessary to control later 
germinating weeds. 
LOW-VOLUME BROADCAST APPLICATION 
(LOW-RATE TECHNOLOGY) 
When applied as directed under the conditions described, this product will control the 
weeds listed below when: 
• Water carrier volumes are 3 to 20 gallons per acre for ground applications and 3 to 5 
gallons per acre for aerial applications. (See the "Aerial Application" section of this 
label for approved sites.) 
• A nonionic surfactant added at 0.5 to I percent by total spray volume may increase 
performance of this product. Use 0.5 percent surfactant concentration when using 
surfactants that contain at least 50 percent active ingredient or a I percent surfactant 
concentration for those surfactants containing less than 50 percent active ingredient. 
• The addition of2 percent dry ammonium sulfate by weight or 17 pounds per 100 
gallons of water may increase the performance of this herbicide on annual weeds. The 
improvement in performance may be apparent where environmental stress is a 
concern. Refer to the "Mixing, Additives and Application Instructions" section of this 
label. 
• Check SPecific crop sections for residual tank mix recommendations. 
• For weeds that have been mowed, grazed, or cut, allow regrowth to occur prior to 
treatment. 
• Refer to the "Tank Mixtures" portion of this section for control of additional 
broadleaf weeds.

nutsedge plants and immature nutlets attached to treated plants. Treat when plants are in 
flower or when new nutlets can be found at rhizome tips. Nutlets, which have not 
germinated, will not be controlled and may germinate following treatment. Repeat 
treatments will be required for long-term control. Wait 7 days after treatment before 
tillage. Tillage will stimulate nutlet germination. 
Apply 28 to 56 ounces of this product per acre in 3 to 40 gallons of water per acre to 
provide suppression or partial control of existing nutsedge plants. Treat when plants have 
3 to 5 leaves (less than 6 inches). Repeat treatments will be required to control 
subsequent emerging plants. Wait 7 days after treatment before tillage or mowing. 
Pampas - Apply this product as a 3 to 3-1/2 percent solution using hand-held equipment. 
Apply to plants that are actively growing at or beyond the boot stage of growth. 
Thorough coverage is necessary for best control. 
Phragmites - For partial control of ph rag mites in Florida and the counties of other states 
bordering the Gulf of Mexico, apply 9 quarts per acre as a broadcast spray or apply a 3-
1/2 percent solution from hand-held equipment. In other areas of the U.S. apply 5-1/3 
quarts per acre as a broadcast spray or apply a 2 percent solution from hand-held 
equipment for partial control. For best results, treat during late summer or fall months or 
when plants are actively growing and in full bloom. Treatment before or after this stage 
may lead to reduced control. Due to the dense nature of the vegetation, which may 
prevent good spray coverage or uneven stages of growth, repeat treatments may be 
necessary to maintain control. Visual control symptom will be slow to develop. 
Quackgrass - In Annual Cropping Systems, or in Pastures and Sods Followed by 
Deep Tillage: Apply 1-3/4 to 3-1/2 quarts of this product per acre. For the 1-3/4 quart 
rate, apply in 3 to 20 gallons of water per acre. For the 3 -112 quart rate, apply in 10 to 40 
gallons of water per acre. Do not tank mix with residual herbicides when using the 1-3/4 
quart rate. Spray when quackgrass"is 8 to 12 inches in height and actively growing. Do 
not till between harvest and fall applications or in fall or spring prior to spring 
application. Allow 3 or more days after application before tillage. In pastures or sods, for 
best results use a moldboard plow. 
Quackgrass - Pasture or Sod or Other Non-crop Areas Where Deep Tillage is Not 
Planned Following Application: Apply 3-1/2 to 5- 113 quarts in.10 to 40 gallons of 
water per acre. Spray when the quackgrass is greater than 8 inches tall and actively 
growing. Do not till between harvest and fall application or in fall or spring prior to 
spring application. Allow 3 or more days after application before tillage.

When applied as directed this product will suppress vegetative growth as indicated 
below. 
Bahiagrass 
This product will provide significant inhibition of seedhead emergence and will suppress 
vegetative growth for a period of approximately 45 days with a single application and 
approximately 120 days with sequential applications. Apply this product 1 to 2 weeks 
after full green-up or after mowing to a uniform height of3 to 4 inches. Applications 
must be made prior to seedhead emergence. Apply 10-112 fluid ounces of this product in 
10 to 25 gallons of water per acre. 
Sequential applications of this product plus nonionic surfactant may be made at 
approximately 45-day intervals to extend the period of seedhead and vegetative growth 
suppression. For continued seedhead suppression, sequential applications must be made 
prior to seedhead emergence. Apply no more than 2 sequential applications per year. As a 
first sequential application, apply 7 fluid ounces of this product plus nonionic surfactant. 
A second sequential application of3-112 to 7 fluid ounces may be made approximately 45 
days after the last application. 
Bermudagrass 
For bumdown, apply 1-3/4 to 3-1/2 quarts of this product in 3- to 20 gallons of water per 
acre. Use this treatment only if reduction of the Bermudagrass stand can be tolerated. 
When bumdown is required prior to harvest, allow at least 21 days to ensure sufficient 
time for bumdown to occur. Adding 0.5 to 1 percent nonionic surfactant by total spray 
volume may enhance bumdown. 
Suppression only - Apply 10-112 to 28 fluid ounces in 3 to 20 gallons of water per acre no 
sooner than 1 to 2 weeks after full green-up. Mowing prior to application may occur 
provided a minimum height of 3 inches is maintained. Rates of 10-112 to 18 fluid ounces 
should be used in shaded conditions or where a lesser degree of suppression is desired. 
Sequential applications may be made when regrowth occurs' and Bermudagrass injury 
and stand reduction can be tolerated. Adding 0.5 to 1 percent nonionic surfactant by total 
spray volume may enhance bumdown.
