GENERAL INFORMATION 
Product Description: This product provides postemergence. systemic control of many annual grasses 
and broadleaf weeds and suppression of perennial weeds in Roundup Ready® corn. The product will also 
provide residual control of selected grasses. 
This product can be applied postemergence to Roundup Ready corn from seedling emergence until the 
corn reaches I J inches in height. A single in-crop application of this product is not to exceed 2.0 quarts 
per acre. 
Make a single application of this product only to com hybrids designated as containing the Roundup 
Ready gene. Applying this product to corn bybrids which are not designated as Roundup Ready will 
result in severe crop injury and yield loss. The Roundup Ready designation indicates that the corn 
contains a patented gene which provides tolerance to this herbicide. Information on Roundup Ready corn 
may be obtained from your seed supplier or Monsanto Representative. 
The product is formulated as a emulsion in water (EW). It may be applied through most standard 
industrial or field-type sprayers after dilution and thorough mixing with water according to label 
instructions. 
Time to Symptoms: This product moves through the plant from the point of foliage contact to and into 
tbe root system. Visible effects on most annual weeds occur within 2 to 4 days. but on most perennial 
weeds may nO! occur for 7 days or more. Extremely cool or cloudy weather following treatment may slow 
activity of this product and delay development of visual symptoms. Visible effects are a gradual wilting 
and yellowing of the plant which advances to complete browning of above-ground growth and 
deterioration of underground plant pans. 
For preemergence activity moisture in the form of rainfall or irrigation is required after application to 
move this proouct into the weed gennination zone. The amount of moisture requjred depends on the soil 
moisture content at the time of application. soil type. and plant residues. Performance is improved when 
1/3 to 10 incb of moisture is received within one week after application and prior to weed emer$ence. 
High intensity or excessive rainfall or irrigation after application may reduce preemergence weed c:<'IJ!10j' 
on coarse soils. . .... • .... 
Stage of Weeds: Annual weeds are easiest to control when they are small (2-4 inc~'ll'Hl. Apply the 
product prior to when weeds become competitive with the corn. Refer to the WEErlS CONTR~]'). 
section for recommendations for specific weeds. • •••• : •••• 
Always use the highest labeled rate of this product when weed growth is heavy or densp.

Do nOl treat weeds under poor growing conditions such as drought stress, disease or insect damage, as 
reduced weed contTol may result. Reduced resullS may also occur when treating weeds heavily covered 
with dust. 
RainIastness: Heavy rainfall soon after application may wash this product off of the foliage and a repeat 
application may be required for adequate control. 
Spray Coverage: For best results. spray coverage should be uniform and complete. Do nOl spray weed 
foliage to the point of runoff. 
Tank Mixing: Read and carefully observe the cautionary statemenlS and all OIher information appearing 
on the labels of all herbicides used. Use according to the most restrictive label directions for each product 
in the mixture. 
Buyer and all users are responsible for all loss or damage in connection with the use or handling of 
mixtures of this product with herbicides or other materials that are not expressly recommended in this 
labeling. Mixing this product with herbicides or other materials not recommended on this label may result 
in reduced performance. 
Maximmn Use Rate: Except as otherwise specified in a crop section of this label. the maximum 
postemergence rate for a single application must nOl exceed 2.0 quarts of this product per acre per 
application in Roundup Ready corn. If additional weed control is needed after the corn is II inches tall. 
Roundup is recommended. Follow the Roundup label USE RESTRICTIONS and PRECAUTIONARY 
STATEMENTS for later postemergence applications in Roundup Ready corn.

4. Add tank mix components. If a wenable powder is used, make a slurry with water, and add it 
SLOWLY through the screen into the tank. Continue agitation. If f10wable herbicides are used, add 
slowly through screen into the tank. Mixing and compatibility may be improved when f10wable is 
premixed one part f10wable with one part water. Add diluted mixture SLOWLY through the Screen 
into the tank. 
5. Add the recommended amount of this product near the end of the filling process SLOWLY through 
the screen into the tank and mix well. Mixing and compatibility may be improved when this product 
is prediluted with two parts of water and added to the tank in diluted form. 
6. Complete filling the sprayer tank with water. If Roundup® is used, add the required amount near the 
end of the filling process. Remove hose from tank immediately to avoid siphoning back into the water 
source. Maintain good agitation at all times until the contents of the tank are sprayed. 
Maintain good agitation at all times until the contents of the tank are sprayed. NOTE: If spray mixture is 
allowed to settle at any time. thorough agitation is required to resuspend the mixture before spraying is 
resumed. 
Keep bypass 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. Check for 
even distribution of spray droplets. For best results with ground application, use flat fan or whirl-chamber 
nozzle. To reduce loss of chemical due to drift of a fine mist, apply at pressures less than 4{) psi. 
MIX ONLY WITH CLEAN WATER. Reduced weed control may occur if muddy water is used, such as 
water from ponds or ditches. 
Due to crop injury, it is not recommended that pestemergence applications of this product be made to 
Roundup Ready corn using fluid fertilizer as the carrier because severe crop injury may occur. Adding 
surfactants. additives containing surfactants, micronutrients, and liquid fertilizers are NOT recommended 
as crop injury may occur. 
Tank mixes with products other than those included in this label are not recommended. 
Ammonium Sulfate - The addition of ammonium sulfate in the spray solution may increase the 
performance of this product on emerged annual weeds under adverse growing conditions. Wben using 
ammonium sulfate. add I to 2 percent dry ammonium sulfate by weight or 8.5 to 17 pounds per 100 
gallons of water. Ammonium sulfate should be added 10 the water in the spray tank and completely 
dissolved prior to adding herbicide. The equivalent rate of ammonium sulfate in a liquid formulation may 
also be used. 
If ammonium sulfate is added directly to.me spray tank, add slowly with agitation. Adding too quickly 
may clog outlet lines. Nozzle tip plugging may result from the use of low-quality ammonium sulfate. To 
determine quality, perform a jar test by adding 113 cup of ammonium sulfate to I gallon of water and 
agitate for I minute. If undissolved sediment is observed, predissolve the ammonium sulfate in water and 
filter prior to addition 10 the spray tank. Following use of ammonium sulfate, thoroughly rinse th" .p""¥.

AVOID DRIFT. EXTREME CARE MUST BE USED WHEN APPLYING THIS PRODUCT TO 
PREVENT INJURY TO DESIRABLE PLANTS AND CROPS. 
Do not allow the herbicide solution to mist, drip. drift or splash onto desirable vegetation since minute 
quantities of this product can cause severe damage or destruction to the crop. plants or other areas on 
which treatment was not intended. The likelihood of injury occurring from the use of this product 
increases when winds are gusty. as wind velocity increases. when wind direction is constantly changing or 
when there are other meteorological conditions that favor spray drift. When spraying. avoid combinations 
of pressure and nozzle type that will result in splatter or fine particles (mist) which are likely to drift. 
A VOID APPLYING AT EXCESSIVE SPEED OR PRESSURE. 
Postemergence Broadcast Application to Roundup Ready Corn - This product may be applied 
postemergence until Roundup Ready corn reaches 11 inches in height. Use conventional ground sprayers 
equipped with nozzles that provide accurate and uniform application. Be certain that nozzles are 
uniformly spaced and are the same size. Calibrate sprayer before use and recalibrate at the start of each 
season. Apply this product and labeled tank mixtures in 10 to 25 gallons of' water per acre unless 
otherwise specified. Do not apply during periods when winds are gusty or any other conditions which 
favor drift. 
As density of weeds increases. spray volume should be increased within the recommended range to ensure 
complete coverage. Carefully selec! correct nozzles and spray pressure to avoid spraying a fine mist. For 
best results with ground application equipment. use flat fan nozzles or a drift reducing nozzle with a 
droplet size of 400-800 microns. Check for even distribution of spray droplets. 
WEEDS CONTROLLED 
When applied as directed under conditions described. this product will control or reduce competition from 
the following EMERGED WEEDS. 
• Apply this product POSTEMERGENCE to Roundup Ready Corn when the weeds are 2-4 inches tall 
and prior to the corn height reaching II inches .. 
• Reduced control of emerged weeds may occur when weeds are under poor growing conditions such as

reaches II inches in height. A single in-crop application of this product is not to exceed 2.0 quans per 
acre. Normal use rales are between 1.5 and 2.0 quans per acre based OIl weed species, weed size and weed 
density at the time of the poslemergence application. Use the higher rale on larger weeds and where 
heavy weed infestations exist. This product should be applied when weeds are 2-4 inches in height and 
before the weed heighl andlor density become competitive with the crop. 
Annual weeds--For difficult-to-control annual weeds such as fall panicum, barnyardgrass, crabgrass, 
shanercane, broadleaf signal grass and Pennsylvania smartweed, apply this producl al 2 quarts per acre. 
For other labeled annual weeds, apply 1.5 10 2 quarts of this product per acre. Use the higher rales in 
areas of heavy weed pressure and when targeting perennial weeds to reduce competition. ; ••• : • 
When applied as directed under the conditions described. this product will control many emerged ~ . 
weeds, suppress many emerged perennial weeds, and provide preemergence contro~ PI; ~pression pf 
many annual grasses in Roondup Ready corn. See WEED CONTROLLED section:Of tni' label for ••

NOTE: For hard-tcrcontrol weeds, additional amounts of Harness® herbicide and/or atrazine may be 
added to the recommended treatment rates for this product to provide improved residual control from a 
postemergence application in Roundup Ready corn. For more consistent control of cornman cocklebur, 
annual morningglory or velvetleaf, atrazine may be applied so that the total atrazine is at least 1.5 Ib 
active ingredient per acre on medium textured soils with less that 3 percent organic matter, and 1.5 to 2 Ib 
active ingredient per acre on medium and fine textured soils with 3 percent or greater organic matter. 
Atrazine up to a maximum rate of 2 Ibs. active ingredients per acre can be applied postemergence. Up to 
2 quarts of alrazine 4L per acre (or 2.2 Ibs. per acre of atrazine 9ODF) could be applied with this product. 
If additional postemergence alrazine treatment is to be applied following an earlier atrazine application, 
the total alrazine applied may not exceed 2.5 Ibs. active ingredient per acre per calendar year. 
NOTE: The maximum application rate of atrazine is 2.5 pounds active ingredient per acre per calendar 
year (2.5 quarts per acre atrazine 4L). On highly erodible soils (as defined by the Soil Conservation 
Service with less than 30 percent residue cover, the maximum rate of atrazine is 1.6 pounds active 
ingredient (1.6 quarts per acre of atrazine 4LJ. On soils nor highly erodible or on highly erodible soils 
with more than 30 percent plant residue cover, the maximum rate of atrazine is 2 pounds active ingredient 
per acre (2 quans per acre of atrazine 4L).
