General Information 
This herbicide controls many annual broadleaf and grass weeds in 
corn, sorghum, sugarcane, pineapple, and certain o~her crops 
specified on this label. It is also effective in nancrop areas 
and industrial sites for control of most annual dnd many peren­
nial broadleaf and grass weeds. This product may be applied 
........ ~b~foT'e.l:i't"-1!I'ft~'~~e~E'i: .... ·,.-i;'iL ~ .. ~-.,,,",,-::c.:.:~, ... _o_~o_ .. '''''-.----..... -
Following many years· of continuous use of-th~i-s..:.p.r.oo.uct-and 
chemically related products, biotypes of some of the ~eeds 
listed on this label have been reported which cannot be 
effectively controlled by this and r.elated herbicides. Where 
this is known or suspected, we recommend the use of this product 
in combination with other registered herbicides which are not 
triazines. Consult with your state Agricultural Extension 
Service for specific recommendations. 
Since this product acts mainly through root absorption, its 
effectiveness depends on moisture to move it into the root zone. 
If weeds develop, a shallow cultivatio~ or rotary hoeing will 
generally result in better weed control. 
This product is nonflammable. 
Avoid using near adjacent desirable plants or in greenhouses, or 
injury may occur. 
WherE the use directions give a range of rates, use the lower 
rate on coarse-textured soil and soil low in organic matter; use 
the higher rate on fine-textur~d soil and soil high in organic 
matter. 
Note: CIBA-GEiGY does not recommend applications in combination 
with other herbicides or oils, except as specifically described 
on the label or in literature published by CIBA-GEIGY. 
~lication Procedures 
Ground application: 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.

through a correctly positione? sparger tube or jets. 
Use screens to protect the pu@p and to prevent nozzles from 
clogging. Screens placed on the suction side of the pump should 
be 16-mesh or COarser. Do not place a screen in the recircula­
tion line. Use 50-mesh or coarser screens between the pump and 
boom, and where required. at the nozzles. Check nozzle manufac­
turer's recommendations. 
For band applications, calculate amount to be applied per acre 
as follows: 
band width in inches 
row width in inches x broadcast rate 
per acre 
amount needed 
per acre of field 
Aerial application: Use aerial application only where broadcast 
applications are specified. Apply in a minimu~ of 1 qt of water 
for each quart of AAtrex 5L applied per acre. For postemergence 
treatments on corn and sorghum, apply recommended rate in a 
minimum of 2 gal of water/A. Avoid applications under condi­
tions where uniform coverage cannot be obtained or where exces­
sive spray drift may occur. 
Avoid ar~'lication to humans or animals. Flagmen and loaders 
should avoid inhalation of spray mist and prolonged contact with 
skin. and should wash thoroughly before eating and at the end of 
each day's operation. 
Application in water or liquid fertilizer: Nitrogen solution or 
complete liquid fertilizer may replace all or part of the water 
as a carrier for preemergence, preplant incorporated, or pre­
plant surface ground application on corn and sorghum. Check the 
compatibility of this product with liquid fertilizer and/or 
nitrogen solution as shown below before use. Do not apply in 
nitrogen solution or complete liquid fertilizer after corn or 
sorghum emerges, except as noted under Lay-by treatment for 
corn, or crop injury may occur.

container of fluid 'fertilizer in the proportions shown helow. 
For different spray volume or herbicide rate, make appropriate

product to one pint of fluid fertilizer (assuming a volume of 25 
gal/A) . 
For each pound of dry product to be applied per acre, add 1 level 
teaspoon or 5 milliliters of the product to one pint of fluid 
fertilizer (assuming a volume of 25 gal/A). 
After thorough mixing, let stand for 5 minutes. If the 
herbicide/fertilizer combination remains mixed, or can be remixed 
readily, the mixture is compatible and can be sprayed. If it is 
not compatible, make a water slurry with the herbicide before 
adding fertilizer and use the mixture only if this test shows it 
is compat i ble. 
Application in water plus emulsifiable oil or oil concentrate: 
Adding emulsifiable oil or oil concentrate to postemergence 
water-based sprays on corn and sorghum may improve weed control. 
However, under certain conditions, the use of either type of oil 
may seriously injure the crop. To mi~imize this possibility, 
observe the following directions. 
Use a crop oil containing 1-2% suitable emulsifier, or a suitable 
crop oil concentrate containing not more than 20% emulsifier ~r 
surfactant blend. Emulsifiable oil and oil concentrate contami­
nated with water or other materials can cause compatibility 
problems and/or crop injury. 
Mixing procedures - all uses: (1) Be sure sprayer is clean and 
not contaminated with any other materials, or crop injury or 
sprayer clogging may result. (2) Fill tank 1/4 full with clean 
water, nitrogen solution, or complete liquid fertilizer. 
(3) Start agitation. (4) Be certain that the agitation system 
is working properly and creates a rippling or rolling action on 
the liquid surface. (5) Pour product directly from container 
into tank. (6) Continue filling tank until 90% full. Increase 
agitation if nec~ssary to maintain surface action. (7) Add emul­
sifiable oil, oil concentrate, cr tank mix herbicide(s}

Center pivot sprinkler application: 
Preemergence or postemergence: Apply AAtrex 5L alone, or in 
tank mixtures with other herbicides on this label which are 
registered for center pivot application, with irrigation water. 
Apply either after planting before crop and weeds emerge, or 
after crop emergence, but before lay-by (20-30 inches) and 
b~fore weeds exceed 1.5 inches in height. Apply at rates 
recommended on this label. Prepare mixture with a minimum of 
1 part water to 1 part product. Injecting a larger volume of a 
more dilute slurry per hour will assure more accurate 
calibration of metering equipment. Maintain sufficient 
agitation to keep herbicide in suspension. Meter slurry into 
irrigation water during entire period. Apply in 1/2-1 inch of 
water. Use the lower water volume on coarser textured soils, 
the higher volume on finer textured soils. More than 1 inch of 
water may reduce weed control by moving herbicide below the 
effective zone in the sntl. Inject dilute slurry into system 
through a positive displacement pump. 
Refer to supplemental literature published by CIBA-'GEIGY for 
mOre information on calibrating. 
Precautions: (1) ~ply only through irrigation systems con­
taining anti-siphon and check valves to prevent contamination of 
well during sh~tdown and overflow of solution tank. (2) Inject 
ahead of any right angle turn in the main line to insure ade 
guate mixing. (3) Chemical injection P"mps and water pumps must 
have interlocking controls to insure simllitaneous shutoff. 
iil Application when drift may occur from windy conditions, when 
system joints and connections are leaking, or when nozzles are 
not providing uniform distribution may cause crop injury. 
121 Where sprinkler distribution patterns do not overlap suffi­
ciently, unacceptable weed control may result. Where sprinkler 
distribution patterns overlap excessively, crop injurv may 
result.

Precautions for applications with emulsifiable oil or oil concen­
trate in water: (1) Do not apply when crop is under stress from 
prolonged cold, wet weather, poor fertility, or other factors, or 
when crop is wet and succulent from recent rainfall, or cro? 
injury may occur. (2) Inbred lines or any breeding stock may be 
severely injured by applications with emulsifiable oil or oil 
concentrate. (3) Adding other insecticides, herbicides, liquid 
fertilizers, or other materials is not recommended, because they 
may cause compatibility problems or crop injury. (4) Store and 
handle emulsifiable oil and oil concentrate carefully. Oil 
contaminated with even a small amount of water may not emulsify 
properly when added to the tank. (5) Do not make more than one 
application per season except as recommended for control of yellow 
nutsedge, quackqrass, and Canada thistle.

Aerial application: In order to assure that spray will be con­
trollable within the target area when used according to label 
directions, make applications at a maximum height of 10 ft above 
vegetation, using low drift nozzles at a maximum pressure of 
40 psi, and restrict application to periods when wind speed 
does not exceed 10 mph. To assure that spray will not adversely 
affect adjacent sensitive nontarget plants, apply AAtrex 5L by 
aircraft at a minimum upwind distance of 400 ft from sensitive 
plants.
