PRECAUTIONARY STATEMENTS 
Hazards to Humans and Domestic Animals 
CAUTION: Harmful if swallowed or absorbed through skin. Causes moderate eye irritation. Avoid contact with 
eyes, skin or clothing. 
PERSONAL PROTECTIVE EQUIPMENT (PPE) 
Some materials that are chemically-resistant to this product are listed below. If you want more options, follow the 
instructions for category A on an EPA chemical resistance category selection chart. 
Mixers and loaders must wear: Coveralls over long-sleeved shirt and long pants, chemical-resistant footwear, 
chemical-resistant gloves made of any waterproof material such as nitrile, butyl, neoprene, and/or barrier laminate, 
and chemical-resistant apron. 
Applicators and other (other than mixers and loaders) handlers must wear: Coveralls over long-sleeved shirt 
and long pants, chemical-resistant gloves made of any waterproof material such as nitrile, butyl, neoprene, and/or 
barrier laminate, and chemical-resistant footwear. 
Follow manufacturer's instructions for cleaning/maintaining PPE. If no such instructions for washables exist, use 
detergent and hot water. Keep and wash PPE separately from other laundry. 
ENGINEERING CONTROLS: 
When handlers used closed systems, enclosed cabs or aircraft in a manner that meets the requirements listed in 
the Worker Protection Standard (WPS) for agricultural pesticides [40 CFR 170.240 (d) (4-6)], the handler PPE re­
quirements may be reduced or modified as specified in the WPS. 
USER SAFETY RECOMMENDATIONS 
Users should: 1) Wash hands before eating, drinking, chewing gum, using tobacco or using the toilet. 2) Remove 
clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. 3) Remove 
PPE immediately after handling this product. Wash the outside of gloves before removing. As soon as possible, 
wash thoroughly and change into clean clothing. 
ENVIRONMENTAL HAZARDS 
This pesticide is toxic to fish and aquatic invertebrates. Do not apply directly to water or to areas where surface water is 
present or to intertidal areas below the mean high water mark. Do not apply where weather conditions favor drift from 
areas treated. Do not contaminate water when cleaning of equipment or disposing of equipment washwaters or rinsate. 
Ground Water Advisory: This chemical is known to leach through soil into ground water under certain conditions 
as a result of agricultural use. Use of this chemical in areas where soils are permeable, particularly where the water 
table is shallow, may result in ground water contamination. 
Surface Water Advisory: Unuron may contaminate surface water through spray drift or, under certain conditions, 
from surface runoff into adjacent surface water bodies (ponds, lakes, streams, etc.). For several weeks post-appli­
cation, this product has a high potential to runoff when applied to fields with any of the following conditions: sloping 
land draining into nearby surface waters; very poorly to somewhat poorly drained soils; areas with extremely shallow 
ground water; frequently flooded areas; fields with surface water canals or ditches; and highly erodible land cultivated 
with poor management practices. 
USE INFORMATION 
Unuron DF Herbicide is a dispersible granule to be mixed in water and applied as a spray for selective control of 
weeds in certain crops and for non-selective weed control on non-cropland areas. It is non-corrosive to equipment, 
non-flammable and non-volatile. 
To control susceptible weed seedlings for an extended period of time, apply this product to soil before weed emer­
gence. The degree of control and duration of effect will vary with the amount of chemical applied, soil texture, rainfall 
and other conditions. Higher dosages are needed for soils high in clay or organic matter. Soil low in clay or organic 
matter will require lower dosages to obtain equivalent herbicide performance. Since moisture is needed to activate 
this product, rainfall or irrigation is needed within 2 weeks of application. In the Columbia River Basin, use this 
product only if the crop is sprinkler irrigated. 
When using this product to control emerged weeds, best results are obtained on succulent weeds growing in tem­
peratures of 70°F or higher with high humidity. Where recommended, addition of a surfactant to the spray increases 
contact effects of this product. 
It is suggested that growers limit their first use to small areas as the effect of this product varies with soils, uniformity 
of application and environmental conditions. Follow all label directions on this and any product used in mixtures. 
DIRECTIONS FOR USE 
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Do not apply this product 
in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be

in the area during application. For any requirements specific to your State or Tribe, consult the agency responsible 
for pesticide regulation. 
RESISTANCE 
When herbicides that affect the same biological site of action are used repeatedly over several years to control the 
same weed species in the same field, naturally-occurring resistant biotypes may survive a correctly applied herbicide 
treatment, propagate, and become dominant in that field. 
Adequate control of these resistant weed biotypes cannot be expected. If weed control is unsatisfactory, it may be 
necessary to retreat the problem area using a product affecting a different site of action. 
To better manage herbicide resistance through delaying the proliferation and possible dominance of herbicide re­
sistant weed biotypes, it may be necessary to change cultural practices within and between crop seasons such as 
using a combination of tillage, retreatment, tank-mix partners and/or sequential herbicide applications that have a 
different site of action. Weed escapes that are allowed to go to seed will promote the spread of resistant biotypes. 
It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information on the 
spread and dispersal of resistant biotypes. Consult your agricultural dealer, consultant, applicator, and/or appropriate 
state agricultural extension service representative for specific alternative cultural practices or herbicide recommen­
dations available in your area. 
INTEGRATED PEST MANAGEMENT 
This product may be used as part of an Integrated Pest Management (IPM) program that can include biological, cul­
tural, and genetic practices aimed at preventing economic pest damage. IPM principles and practices include field 
scouting or other detection methods, correct target pest identification, population reach locally determined action 
thresholds. Consult your state cooperative extension service, professional consultants or other qualified authorities 
to determine appropriate action treatment threshold levels for treating specific pest/crop systems in your area. 
GRASSES AND BROADLEAF WEEDS CONTROLLED BY THIS PRODUCT 
PREEMERGENCE USE (GERMINATING WEEDS) 
This product at specified rates, controls annual weeds such as: 
Broadleaved Weeds 
Carpetweed Nettleleaf goosefoot 
Chickweed Pigweed 
Common dayflower Purslane (common) 
Florida beggarweed Ragweed (common) 
Florida purslane (Florida pusley) Shepherdspurse 
Galinsoga Smartweed (Pennsylvania) 
Lambsquarters Wild radish 
Mustard 
Grasses 
8arnyardgrass (watergrass) Fall panicum 
Canarygrass Foxtails (including giant) 
CrabQrasses Goosegrass 
This product will provide partial control of the following: 
Partial Control 
Annual morningglory Sickle pod 
Cocklebur (common) Velvetleaf (buttonweed) 
Eastern black nightshade Waterhemp 
Prickly sida (teaweed) 
The lower dosage rates are effective on coarser soils and the higher rates on finer soils and on the more resistant 
seedling weeds. Sufficient moisture (one-half to 1 inch on moist soils; 1 to 2 inches on dry soils) in the form of rainfall 
or sprinkler irrigation is necessary after treatment to carry the chemical into the root zone of germinating weeds; 
best results are obtained when this occurs within two weeks after application. If heavy rainfall occurs soon after ap­
plication, injury to crop may result. 
This product applied pre-emergence, before emergence of Asparagus, Carrots, Corn (field), Parsnips, Potatoes, 
Soybeans and weeds, is an effective procedure because susceptible weeds are controlled in an early, vulnerable 
seedling stage before they compete with the crop. With favorable moisture conditions, this product continues to con­
trol weeds for some time as the crop becomes better able to compete. Should weed seedlings begin to break through 
the pre-emergence treatment in significant numbers, secondary weed control procedures should be implemented. 
These include cultivation and post-emergence herbicide application. 
A good seed bed must be prepared before application of this product as crop injury may result if application is made

to ground which is cloddy or compacted resulting in improperly planted seed. Plant seed to depth specified. Surface 
of the soil should not be cultivated or disturbed after application of this product and before emergence of the crop 
as weed control may be reduced and crop injury may result. However, if moisture is insufficient to activate the her­
bicide, a shallow cultivation (rotary hoe preferred) should be made after emergence of row crops while weeds are 
small enough to be controlled by mechanical means. Deep cultivation reduces the effectiveness of this product. 
POST-EMERGENCE USE (Emerged Seedling Weeds): This product, at specified rates, controls weeds such as: 
Broadleaved Weeds 
Annual morning glory Lambsquarters 
Carpetweed Mustard 
Chickweed (common) Nettleleaf goosefoot 
Cocklebur (common) Pigweed 
Common dayflower Prickly sida (teaweed) 
Common ragweed Purslane (common) 
Dog fennel Sesbania 
Fiddleneck (Amsinckia) Sickle pod 
Florida beggarweed Smartweed, (Pennsylvania) 
Florida purslane (Florida pusley) Velvetleaf (buttonweed) 
Groundsel Wild buckwheat 
Knawel 
Grasses 
Annual ryegrass Fall panicum 
Barnyardgrass (watergrass) Foxtail (including giant) 
Broadleaf signalgrass Goosegrass 
Canarygrass Rattail fescue 
Crabgrass Texas panicum 
Results of post-emergence treatment of emerged weeds vary with rate applied and environmental conditions. Best 
results are obtained on succulent weeds growing under conditions of high humidity and temperatures of 70°F or 
higher. Addition of a surfactant such as Surf-Ac® 820 to the spray (where recommended), increases contact effects 
of this product. Application will also provide control of emerging susceptible weed seedlings for an extended period 
of time 
AGRICULTURAL USE REQUIREMENTS 
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR Part 170. 
This standard contains requirements for the protection of agricultural workers on farms, forests, nurseries, green­
houses and handlers of agricultural pesticides. It contains requirements for training, decontamination, notification 
and emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on 
this label about personal protective equipment (PPE) and restricted entry interval (REI). The requirements in this 
box only apply to uses of this product that are covered by the Worker Protection Standard. 
Do not enter or allow worker entry into treated areas during the restricted entry interval of 24 hours. 
PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves 
contact with anything that has been treated, such as plants, soil or water is: Coveralls, chemical-resistant gloves 
made of any waterproof material, shoes plus socks, and chemical-resistant headgear for overhead exposure. 
NON-AGRICULTURAL USE REQUIREMENTS 
The requirements in this box apply to uses of this product that are not within the scope of the Worker Protection 
Standard for agricultural pesticides (40 CFR Part 170). The WPS applies when this product is used to produce 
agricultural plants on farms, forests, nurseries or greenhouses. Non-crop weed control is not within the scope of 
the Worker Protection Standard. Do not enter or allow unprotected persons to enter treated areas until the sprays 
have dried. 
APPLICATION DIRECTIONS: This product must be used only in accordance with this label. Injury to or loss of 
desirable trees or other plants may result from failure to observe the following: 
• Do not apply by air. 
• Do not apply to sand or loamy sand. 
• Do not use on soils with less than 1 % organic matter. 
GROUND APPLICATION: Use a fixed-boom power sprayer calibrated to a constant speed and rate of delivery. 
Openings in screen should be equal to or larger than 50 mesh. Continuous agitation in the spray tank is necessary 
to keep the material in suspension. Agitation can be by hydraulic or mechanical means. If a by-pass or return line is 
used, it should terminate at the bottom of the tank to minimize foaming. Avoid overlapping of spray swaths and shut 
off spray booms while starting, turning, slowing or stopping or crop injury may result. 
LlNURON OF Page 4 of 12

( C 
For pre-emergence application, use a minimum of 15 gallons of water per acre. For post-emergence application, 
use sufficient volume of water (minimum of 25 gallons per acre) for thorough coverage of weed foliage. Always apply 
in a manner and under conditions favorable to avoid spray drift. 
CLEANING: Equipment should be cleaned of all traces of this product immediately after use. Nozzle tips and screens 
should be removed and cleaned separately. Flush tank, pump, hoses and boom with several changes of water. 
Equipment should not be flushed or drained, or this product applied near desirable trees or other plants, or on areas 
where their roots may extend, or in locations where the chemical may be washed or moved into contact with their 
roots. This product should not be used on home plantings of trees, shrubs or herbaceous plants, lawns, walks, 
driveways, tennis courts or similar areas. Keep drift of dry powder or spray from desirable plants. 
SPRAY PREPARATION: The tank should be one-quarter full with clean water. Start agitation system, add this prod­
uct and continue adding water. Each component of any tank mix should be added separately while adding water. 
Surfactant, if used, should be added last when the tank is nearly full. Agitation should continue throughout. If poor 
mixing should occur with any component, premix the component with two parts water before adding to the spray 
tank. 
RATES: All rates are expressed as broadcast rates. For band treatment, use proportionately less. For example, use 
one-third of the broadcast rate when treating a 14 inch band where row spacing is 42 inches. Where a range of 
dosages is given, use the lower rate on coarser soils (low in clay or organic matter) and the higher rate on finer soils 
(high in clay or organic matter). For post-emergence application, use the lower rate on smaller weeds and the higher 
rate on larger weeds. See crop sections for rates for specific crops. 
REPLANTING: If initial seeding fails to produce a stand, any crop registered for the rate of this product that was ap­
plied may be replanted immediately. Thoroughly rework soil before replanting. Do not retreat field with second ap­
plication as injury to the crop may result. 
CROP ROTATION DIRECTIONS: 
East of the Rocky Mountains 
• Any crop registered for the rate of linuron that was applied may be replanted immediately. 
• Any crop may be planted after 4 months, except for cereals, where only barley, oats, rye, and wheat may be 
planted. 
• Cereal crops not listed above may be planted after 12 months. 
West of the Rocky Mountains 
• Any crop registered for the rate of linuron that was applied may be replanted immediately. 
• Do not plant any other crop until 12 months after the last application of this product as crop injury may result. 
FERTILIZER SPRAY MIXTURES: For pre-emergence application, non-pressure nitrogen or fertilizer solution may 
be used in the spray mixture unless otherwise directed. Small quantities should be tested for compatibility by the 
following procedure before full scale mixing. 
1. Measure one pint of intended spray water or fertilizer solution into a jar. 
2. Add in the order given the intended ingredients, shaking after each addition. 
(a)Surfactants (spreaders), acidifiers, compatibility agents and activators: add 1 teaspoon for each pintl100 gal-
lons. 
(b) Dry ingredients (wettable powders, dry flowables): add 1 tablespoon for each pound/100 gallons. 
(c) Flowables: add 1 teaspoon for each pintl100 gallons. 
(d) Soluble ingredients: add 1 tablespoon for each pound/100 gallons. 
(e)Spreaders/stickers: add 1 teaspoon for each pintl100 gallons. 
3. The final mixture should be uniform and smooth with no evidence of coagulation occurring. If incompatibility is 
evident, begin test again with a compatibility agent added first. Six drops is equivalent to 4 ounces per 100 gallons, 
If this does not smooth the mixture, try higher concentrations and other compatibility agents. 
4. Allow the mixture to stand undisturbed thirty minutes. If separation occurs, shake and observe the resulting mix­
ture. If mixture is smooth, proceed with spraying, provided the tank has good agitation. If mixture is not smooth, 
do not spray. You may try: 
(a) more compatibility agents. 
(b) different formulations of the active ingredients (switch from WP or EC to flowable or from WP to EC). 
(c) change active ingredients; some combinations will not tank mix. 
CHEMIGATION INSTRUCTIONS

( 
Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public water 
system unless the pesticide label-prescribed safety devices for public water systems are in place. 
A person knowledgeable of the chemigation system and responsible for its operation or under the supervision of the 
responsible person, shall shut the system down and make necessary adjustments should the need arise. 
CHEMIGATION SYSTEMS CONNECTED TO PUBLIC WATER SYSTEMS 
Public water system means a system for the provision to the public of piped water for human consumption if such 
system has at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 60 
days out of the year. 
Chemigation systems connected to public water systems must contain a functional, reduced-pressure zone, backflow 
preventer (RPZ) or the functional equivalent in the water supply line upstream from the point of pesticide introduction. 
As an option to the RPZ, the water from the public water system. should be discharged into the reservoir tank prior 
to pesticide introduction. There shall be a complete physical break (air gap) between the outlet end of the fill pipe 
and the top or overflow rim of the reservoir tank of at least twice the inside diameter of the fill pipe. 
The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow 
of fluid back toward the injection pump. 
The pesticide injection pipeline must contain a functional, normally closed, solenoid-operated valve located on the 
intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from 
the supply tank when the irrigation system is either automatically or manually shut down. 
The system must contain functional, interlocking controls to automatically shut off the pesticide injection pump when 
the water pump motor stops, or in cases where there is no water pump, when the water pressure decreases to the 
point where pesticide distribution is adversely affected. 
Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump) effec­
tively designed and constructed of materials that are compatible with pesticides and capable of being fitted with a 
system interlock. 
Do not apply when wind speed favors drift beyond the area intended for treatment. 
When mixing, fill nurse tank half full with water. Add this product slowly to tank while hydraulic or mechanical agitation 
is operating and continue filling with water. Stickers, spreaders, insecticides, nutrients, etc. should be added last. If 
compatibility is in question, use the compatibility jar test before mixing a whole tank. Because of the wide variety of 
possible combinations which can be encountered, observe all cautions and limitations on the label of all products 
used in mixtures. 
This product should be added through a traveling irrigation system continuously or at the last 30 minutes of solid 
set or hand moved irrigation systems. Agitation is recommended. Shut off injection equipment after treatment and 
continue to operate irrigation system until this product has been cleared from the last sprinkler head. 
SPRINKLER CHEMIGATION 
The system must contain a functional check valve, vacuum relief valve and low pressure drain appropriately located 
on the irrigation pipeline to prevent water source contamination from backflow. 
The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow 
of fluid back toward the injection pump. 
The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated valve located on 
the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn 
from the supply tank when the irrigation system is either automatically or manually shut down. 
The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when 
the water pump motor stops. 
The irrigation line or water pump must include a functional pressure switch which will stop the water pump motor 
when the water pressure decreases to the point where pesticide distribution is adversely affected. 
Systems must use a metering pump, such as a positive displacement injection pump (e.g. diaphragm pump) effec­
tively designed and constructed of materials that are compatible with pesticides and capable of being fitted with a

• Do not use surfactant or fertilizer solution in spray mixture. 
• Do not apply within 1 day of harvest. 
DIRECT SEEDED OR NEWLY PLANTED CROWNS 
Pre-emergence Application: Make a single application of 2 to 4 pounds per acre after planting seed one-half inch 
deep in coarse soil and 1 inch deep in fine soils. During planting operation, spray activated charcoal as a 1 inch 
band on soil surface directly over seed rows at the rate of 300 pounds per acre (equivalent to 15 pounds per acre 
of crop with 20 inch row spacing). Pre-emergence weed control will be reduced in soils with high organic matter 
(greater than 5% and peat or muck). 
Post-emergence Application: Make 1 or 2 applications of 1 to 2 pounds per acre when ferns are in 6 inches to 18 
inches stage and weeds are not over 4 inches tall. 
ESTABLISHED BEDS 
Pre-emergence Application: Make a single application of 2 to 4 pounds per acre. Pre-emergence weed control 
will be reduced in soils with high organic matter (greater than 5% and peat or muck.) 
Post-emergence Application: Make 1 to 3 applications of 1 to 2 pounds per acre before weeds exceed 4 inches 
in height. Apply before cutting season or immediately after cutting. 
Directed Post-emergence Application (Fern Stage): Make a single application of 4 pounds per acre as directed. 
Spray to base of plants for control of Dudain melon. In California, Dudain melon and annual Nightshade are con­
trolled. 
BULBS-Tulip, Caladium, Calla Lily, Daffodil and Dutch Iris (California, Florida) 
After planting of bulbs, settle the soil with sprinkler irrigation (rainfall will serve the same purpose). Before emergence 
of plants (bulbs), apply 2 pounds of this product per acre in a minimum of 20 gallons of water per acre. Treat only 
once during growing season. 
CARROTS 
Because Carrot varieties vary in their resistance, determine tolerance to this product prior to adoption as a field 
practice to prevent possible crop injury. 
• Do not exceed 4 pounds of this product per acre per year East of Rocky Mountains. 
• Do not exceed 3 pounds of this product per acre per year West of Rocky Mountains. 
• Do not apply within 14 days of harvest. 
Pre-emergence Application-California, Colorado, Florida, Michigan, Minnesota, New Jersey, 
North Dakota, Ohio, Oregon, Washington, and Wisconsin only 
Make a single application of 1 to 2 pounds per acre in California, Florida, Minnesota, North Dakota, Oregon and 
Washington, and 1 to 3 pounds per acre in Colorado, Michigan, New Jersey, Ohio, and Wisconsin, after planting but 
prior to Carrots emergence. Plant seed at least one-half inch deep. Use the lower rate on lighter soils and higher 
rate on heavier soils. Subsequent post-emergence application may be made provided the total does not exceed the 
seasonal maximum for the geography. 
Post-emergence Application-Entire U.S.: 
Apply 1.5 to 3 pounds per acre as a broadcast spray. 
Applications to Carrots that are less than 3 inches tall may result in crop injury; grower and/or applicator assumes 
all crop injury risk if applications are made to Carrots less than 3 inches tall. Repeat application may be made as 
long as the total use does not exceed the seasonal maximum of this product for the geography. 
Post-emergence Application-Alternate Treatment for New York: For control of emerged broadleaf weeds early 
in the development of the Carrot crop, apply 0.25 pound per acre to Carrots having at least one fully developed true 
leaf and 0.5 pound per acre to Carrots having three or more leaves. A single application applied prior to the 5-leaf 
stage of Carrots may not provide adequate season-long control. Multiple applications at 1- and 3-, and 2- and 4-, or 
3- and 5-leaf stages will significantly improve weed control. Early crop injury can occur; however the effect should 
be transitory, with no yield losses attributable to crop injury. At normal rate, Carrots must be at least 3 inches tall at 
the time of application. Failure to control weeds before this stage of development will result in significant yield losses 
due to weed competition. 
Crop Rotation-California 
Following this product use in Carrots grown to maturity, Barley, Garlic, and Onions may be planted after 6 months 
and Potatoes after 9 months. 
Precautions for Postemergence Carrot Applications: 
• Do not treat susceptible varieties which show an initial burning of foliage following postemergence treatment with 
this product. 
• Do not exceed 40 psi spray nozzle pressure as crop injury may result. 
• Do not apply when temperature exceeds 85°F as crop injury may result. 
• The activity of this product on both Carrots and weeds is increased if applied after 3 or more cloudy days. If spray­
ing is done under these conditions, the dosage of this product must be reduced.

Directed Postemergence Application: Make a single application as a directed spray after Corn is at least 15 inches 
high (measured to the highest leaf surface on free standing plants). Do not spray over top of Corn. Apply only when 
there is sufficient differential between height of Corn and weeds so that the directed spray thoroughly covers all 
weed foliage without contact of upper leaves or whorl of Corn by spray or drift, as such contact may cause crop 
injury. Early cultivation (rotary hoe or other suitable equipment) will aid in achieving proper differential between height 
of Corn and weeds. 
Use 1.25 to 1.5 pounds per acre; add 1 pint of surfactant for each 25 gallons of spray mixture. 
Non-pressure nitrogen solution may be substituted for all or part of the water. 
Use the lower rate on lighter soils (lOW in clay or organic matter) and when weeds do not exceed 2 inches in height; 
use the higher rate on heavier soil (high in clay or organic matter) for weeds up to 5 inches in height. Do not apply 
within 57 days of harvest.

to 4 pounds of this product per acre as a directed spray. Spray should be directed to weed growth and to avoid contact 
with the Poplar plant. Do not spray over the top of the Poplar as injury to the plant will result. Use the lower rate on 
light soils and higher rate on heavier soils. For best results on emerged weeds, treat at the seedling stage. More than 
one treatment may be made but no more than 8 pounds of this product per acre should be applied per year. 
PARSLEY (East of Mississippi River and Texas) 
• Do not exceed a total of 3 pounds of this product per acre per season. 
• Do not apply within 30 days of harvest. 
• In Texas, use on mineral soils only. 
Pre-emergence Application (Mineral and Muck Soils): 
Make a single broadcast application of this product at a rate of 1 to 3 pounds per acre after planting, but before the 
crop emerges. Use lower rates on coarse soils and higher rates on heavier soils. 
Post-emergence Application (Muck Soils Only): 
Make a single application of this product at a rate of 1 pound per acre to control emerged weeds. Apply after Parsley 
has a minimum of 3 true leaves or crop injury may result. Apply when weeds are in the 1 to 3 true leaf stage. 
PARSLEY GROWN FOR SEED (OREGON AND WASHINGTON) 
For best results, apply preemergence to weeds or early postemergence while weeds are small. If weeds are up at 
time of application, add a non-ionic surfactant at 1 quart per 100 gallons to improve weed control performance. 
Before using other kinds of adjuvants, test on a small area to be sure the treatment is safe to the crop. 
Apply this product at 1 to 2 pounds per acre after Parsley has a minimum of 3 true leaves or crop injury may result. 
More than one application can be made providing the user has prior experience to indicate adequate crop safety. 
Wait at least 21 days between applications. Do not treat plants that are under stress. Avoid late Fall applications 
prior to cold weather as crop injury may occur. Do not make more than two applications in the first growing season 
and do not make more than two applications in the second growing season. When using on a new variety for the 
first time, treat a small area to determine crop safety prior to treating a larger area . 
.. User must accept all crop injury liability if an adjuvant other than a non-ionic surfactant at 1 quart per 100 gallons is 
used of if more than one application per crop is made.

Pre-emergence Application: Make a single application of this product as a broadcast spray after planting but before 
crop emerges. Plant seed at least 2 inches deep. If beds are to be "dragged" and/or "hilled", apply after the final 
"dragging" or "hilling" operation. Apply before grasses are 2 inches tall and before broadleafweeds are 6 inches tall, 
preferably just before or when weed seedlings emerge. If emerged weeds are present, add 1 pint Surf-Ac 820 for 
each 25 gallons of spray mixture. In irrigated areas, best results are obtained when application is made to moist 
soil, followed within 2 weeks by 1 to 2 inches of sprinkler irrigation (or rainfall). If soil is dry and powdery, irrigate 
prior to application and follow with sprinkler irrigation to activate the herbicide. 
SORGHUM 
• Do not apply over top of emerged Sorghum. 
• Do not apply 75 days within harvest. 
• Do not graze or feed plants to livestock within 3 months after directed postemergence application. 
Pre-emergence Application: Select a registered herbicide treatment for application as a tank mixture. Make a 
single application after planting, but before crop emerges. In soil with 1 to 2% organic matter, apply 0.5 to 1 pound 
per acre on sandy loam and 1 to 1.5 pounds per acre on loam, silt loam, silt, sandy clay, or sandy clay loam. In soil 
with 2 to 4% organic matter, apply 1 to 1.5 pounds per acre on sandy loam and 1 to 2 pounds per acre on loam, silt 
loam, silt, sandy clay, or sandy clay loam. Plant seed at least 1 inch deep on flat or raised seedbeds only as injury 
to the crop may result. 
Directed Post-emergence Application 
Make a single application of this product as a directed spray. Add 1 pint of Surf-Ac 820 for each 25 gallons spray 
mixture. If sprayer is equipped with skids, shoes or shields, apply 1 pound per acre when Sorghum is 12 inches tall 
(free standing plants) and weeds are up to 2 inches in height. Use 1 to 2 pounds per acre when Sorghum is 15 
inches tall and weeds are 2 to 4 inches in height. Apply only when there is sufficient differential between height of 
Sorghum and weeds so that the directed spray thoroughly covers all weed foliage without contact on upper leaves 
or whorl of Sorghum by spray or drift as such contact may cause crop injury.

NONCROP WEED CONTROL 
Apply 2 to 6 pounds of this product per acre in 40 to 100 gallons of water for short term control of annual weeds on 
noncropland areas such as roadsides and fence rows. Apply shortly before weed growth begins or at early seedling 
stage of growth for best results. Add 2 quarts of Surf-Ac 820 per 100 gallons of spray mixture for control of established 
weeds. Apply as a thorough coverage spray during periods when daily temperatures exceed 70°F and before weed 
growth exceeds 8 inches in height. 
SPRAY DRIFT MANAGEMENT 
The interaction of many equipment and weather-related factors determine the potential for spray drift. The applicator 
is responsible for considering all these factors when making application decisions. 
AVOIDING SPRAY DRIFT IS THE RESPONSIBILITY OF THE APPLICATOR. 
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. The presence of sensitive 
species nearby, the environmental conditions, and pest pressure may affect how an applicator balances drift control 
and coverage. APPLYING LARGER DROPLETS REDUCES DRIFT POTENTIAL, BUT WILL NOT PREVENT DRIFT 
IF APPLICATIONS ARE MADE IMPROPERLY OR UNDER UNFAVORABLE ENVIRONMENTAL CONDITIONS! 
See Wind, Temperature and Humidity, and Temperature Inversions sections of this label. 
Controlling Droplet Size - General Techniques 
• Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with 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 A HIGHER-CA­
PACITY NOZZLE INSTEAD OF INCREASING PRESSURE. 
• 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. 
Controlling Droplet Size - Aircraft 
• Number of Nozzles - Use the minimum number of nozzles with the highest flow rate that provide uniform coverage. 
• Nozzle Orientation - Orienting nozzles so that the spray is emitted backwards, parallel to the airstream will pro­
duce larger droplets than other orientations. 
• Nozzle Type - Solid stream nozzles (such as disc and core with swirl plate removed) oriented stright back produce 
LlNURON DF Page 11 of 12

( 
larger droplets than other nozzle types. 
( 
• Boom Length - The boom length should not exceed three-fourth of the wing or rotor length - longer booms in-
crease drift potential. 
• Application Height - Application more than 10ft. above the canopy increases the potential for spray drift. 
Boom Height 
Setting the boom at the lowest labeled height (if specified) which provides uniform coverage reduces the exposure 
of droplets to evaporation and wind. For ground equipment, the boom should remain level with the crop and have 
minimal bounce. 
Wind 
Drift potential increases at wind speeds of less than 3 mph (due to inversion potential) of more than 10 mph. However, 
many factors, including droplet size and equipment type determine drift potential at any given wind speed. AVOID 
GUSTY OR WINDLESS CONDITIONS. 
Note: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how 
they affect spray drift. 
Temperature and Humidity 
When making applications in hot and dry conditions, set up equipment to produce larger droplets to reduce effects 
of evaporation. 
Temperature Inversions 
Drift ponentiaL is high during a temperature inversion. Temperature inversions restrict vertical air mixing, which causes 
small suspended droplets to remain close to the ground and move laterally in a concentrated cloud. 
Temperature inversions are characterized by increasing temperature 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) indicated an inversion, while smoke that moves upward and 
rapidly dissipates indicates good vertical air mixing. 
Shielded Sprayers 
Shielding the boom or individual nozzles can reduce the effects of wind. However, it is the responsibility of the ap­
plicator to verify that the shields are preventing drift and not interfering with uniform deposition of the product.
