Follow manufacturer's instructions for cleaning/maintaining PPE. If no such instructions 
for washables, use detergent and hot water. Keep and wash PPE separately from 
other laundry. 
Engineering Control Statements 
When handlers use 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 requirements may be reduced or 
modified as specified in the WPS. 
User Safety Recommendations 
Users should: 
• Wash hands before eating, drinking, chewing gum, using tobacco, or using 
-the toilet. 
• Remove clothing immediately if pesticide gets inside. Then wash thoroughly 
and put on clean clothing. 
• 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 
Do not contaminate water when disposing of equipment wash water. 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 allow this material to drift onto neighboring crops or 
noncrop areas or use in a manner or at a time other than in accordance with label 
directions because animal, plant or crop injury, illegal residues, or other undesirable 
results may occur. 
Norflurazon can contaminate surface water through spray drift. Under some conditions, 
norflurazon may also have a high potential for runoff into surface water (primarily via 
dissolution in runoff water) for several months post-application. These include poorly 
draining or wet soils with readily visible slopes toward adjacent surface waters, 
frequently flooded areas, areas over-laying extremely shallow ground water, areas with 
in-field canals or ditches that drain to surface water, areas not separated from adjacent 
surface waters with vegetated filter strips, and areas overlaying tile drainage systems 
that drain to surface water. 
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.

label instructions, contact your state pesticide or environmental control agency or 
hazardous waste representative at the nearest EPA Regional Office for guidance. 
Container DisposalHandling 
Non-refillable container. Do not reuse or refill this container. Completely empty bagaruJ 
triple rinse container into application equipment. Then offer for recycling ·if available or 
dispose of empty bagcontainer in a sanitary landfill, or by incineration, or, if allowed by 
state and local authorities, by burning. If burned, stay out of smoke. 
For minor spills, leaks, etc., follow all precautions indicated on this label and clean up 
immediately. Take special care to avoid contamination of equipment and facilities 
during cleanup procedures and disposal of wastes. In the event of a major spill, fire, or 
other emergency, call 1-800-888-8372, day or night. 
USE PRECAUTIONS 
1. Do not apply this product through any type of irrigation system. 
2. Follow directions for each geographic region, soil type, and crop. Applications in 
geographic regions not specifically mentioned should follow directions for use for 
mid-South, Southeast, and TX (east of 1-35). 
3. Do not graze or feed cotton forage. Do not graze or harvest soybean forage or 
hay within 90 days of last Zorial Rapid 80 application. 
Multiple Applications 
Multiple or sequential applications can be made in certain geographic areas, but the 
total quantity of Zorial Rapid 80 applied in a year must not exceed the broadcast rate in 
pounds per acre for a given soil type. Follow Special Directions for each geographic 
region, soil type, and crop. 
Read mixing, application, and specific crop sections for additional recommendations· 
and precautions. 
Mixing Instructions 
Zorial Rapid 80 may be tank mixed with other herbicides and liquid fertilizer. Herbicides 
that may be tank mixed with Zorial Rapid 80 are listed in each crop section. All tank mix 
products must be approved for use on the respective crop.

If herb,icide(s) do not ball-up or forll1 flakes, sludge, gels, oily films, layers, or other 
precipitates, then the tested spray mix is compatible. Incompatibility in any of the above 
described forms will occur within 5 minutes after mixing. 
If components are incompatible, the use of a compatibility agent approved for 
agricultural use on the respective crop is recommended. Rerun the above compatibility 
test with a suitable compatibility agent C/4 teaspoon is equivalent to 2 pts.l100 gals. of 
spray carrier). 
Clean and calibrate the sprayer. Add Zorial Rapid 80 to the spray tank already filled 
with 1/4 the required volume of the water. This will eliminate or minimize foaming. 
Maintain agitation while filling and spraying. If a bypass line is used, discharge at the 
bottom of the tank to minimize foaming. 
Do not allow Zorial Rapid 80 spray mixture to remain in the spray tank overnight 
because settling could occur and resuspension would be difficult. 
Begin adding wettable powders, flowable liquids, emulsifiable concentrates, and 
surfactants after the spray tank is 3/4 full. Continue agitation during the addition of all 
the materials and while filling and spraying. 
Products should be added to the spray tank in the following order: 
1. Wettable powders and water-dispersible granules. Wettable powders should be 
premixed in a small amount of water. Water-dispersible granules should be 
added during filling. Allow both to disperse before other products are added. 
The order of addition is not important. 
2. Flowable liquids 
3. Emulsifiable concentrates 
4. Surfactants

Note: In addition, Zorial Rapid 80 may not always be compatible with other 
formulations of dinitroaniline (DNA) herbicides. Always predetermine tank mix 
compatibility by mixing small proportional quantities in a quart jar or other small 
container. If after vigorous shaking there are large flakes, gel, sludge, or other signs of 
incompatibility, do not spray the combination. Always follow the order of addition given 
. in the Mixing Instructions section of this label. 
Application Equipment 
Ground Application: Apply the recommended rate of Zorial Rapid 80 in 10 or more 
gals. of water per acre. Apply accurately with a fixed-boom sprayer. Equip sprayer with 
fan-jet nozzle tips or equivalent for broadcast application. Use nozzle tips which 
provide uniform coverage for band applications. Use screen size 50-mesh or larger. 
Be sure to calculate the correct amount of product per acre for band applications. Use 
the following formulas to determine the appropriate rate and volume per treated acre 
needed for band applications:

The solution should be mixed to the maximum label rate and at no point on the field 
should the solution be applied at a concentration any higher than this rate. 
Aerial Application: Apply the recommended rate of Zorial Rapid 80 in 5 or more gals. 
of water per acre. To minimize drift, use Zorial Rapid 80 with a drift control agent such 
as Nalco-Trol®. 
Aerial Drift Management 
Avoiding spray drift at the application site is the responsibility of the applicator. 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 
decisions. 
The following drift management requirements must be followed to avoid off-target drift 
movement from aerial applications to agricultural field crops. These requirements do 
not apply to forestry applications, public health uses, or to applications using dry 
formulations. 
1. The distance of the outermost nozzles on the boom must not exceed % the 
length of the wingspan or rotor.

-10-
2. Nozzles must always point backward parallel with the air stream and never be 
pointed downward more than 45 degrees. 
Where states have more stringent regulations, they should be observed. 
The applicator should be familiar with and take into account the information covered in 
the Aerial Drift Reduction Advisory Information section below. 
Aerial Drift Reduction AdviSOry Information 
Information on 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 
Wind, Temperature and Humidity, and Temperature Inversions). 
Controlling Droplet Size 
• Volume - Use high flow rate nozzles to apply the highest practical spray volume. 
Nozzles with higher rated flows produce larger droplets. 
• Pressure - Do not exceed the nozzle manufacturer's recommended pressures. For 
many nozzle types, lower pressure produces larger droplets. 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 parallel to the 
airstream produces larger droplets than other orientations and is the recommended 
practice. Significant deflection from 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 the largest 
droplets and the lowest drift. 
Boom Length 
For some use patterns, reducing the effective boom length to less than 3/4 of the 
wingspaf) or rotor length may further reduce drift without reducing swath width.

-11-
Application Height 
Applications should not be made at a height greater than 10ft. 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 exposure of 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 edges of the field, the applicator must compensate 
for this displacement by adjusting the path of the aircraft upwind. Swath adjustment 
distance should increase with increasing drift potential (higher wind, smaller drops, etc.) 
Wind 
Drift potential is lowest between wind speeds of 3-10 mph .. However, many factors, 
including droplet size and equipment type, determine drift potential at any given speed. 
Application should be avoided below 3 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 spray 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 
This pesticide 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, nontarget crops) is minimal (e.g., when wind is blowing away from 
the sensitive areas). 
Application Methods 
Preplantlncorporated Application (PPI) and Preplant Applications (PPA) for 
cotton: Apply Zorial Rapid 80 at the recommended rate prior to planting. Incorporate 
PPI applications within one week after application and not deeper than 2-3 inches. 
Preemergence Surface Applications (PRE) for cotton, soybeans, and peanuts: 
Apply Zorial Rapid 80 at the recommended rate prior to the emergence of the crop and 
weeds. Do not apply when the crop is at or near emergence (soil cracking). Emerged 
weeds must be controlled by tillage prior to application or tank mixing with a 
postemergence herbicide, such as Gramoxone® or Roundup®. 
Split Application - The Zorial SpliPM for cotton and soybeans: First apply 112 of the 
Zorial Rapid 80 rate preplant incorporated, then apply the remaining 112 of the Zorial 
Rapid 80 rate preemergence surface as recommended above. 
The soil surface should be free of clods and existing weeds prior to Zorial Rapid 80 
application. Use tillage or a postemergence herbicide to control emerged weeds. 
Dry Bulk Fertilizer/Zorial Rapid 80 Blends for Use in Cotton 
Zorial Rapid 80 may be coated onto dry bulk granular fertilizers for fall or spring early 
preplant surface, preplant incorporated, or preemergence applications. Coating may be 
conducted by either an in-plant bulk system or the on-board system. Individuals or 
agents selling Zorial Rapid 80 in dry bulk fertilizer blends are responsible for following 
all state and local regulations regarding fertilizer/herbicide blending. Rate 
recommendations, restrictions, and weeds controlled are the same as for the sprayable 
product. . 
Slurry the desired amount of Zorial Rapid 80 in an adequate amount of water (3 pts. 
water per lb. of Zorial Rapid 80) required to uniformly cover the fertilizer particle. Apply 
slurry to fertilizer, using any closed rotary-drum mixer or other commonly used dry 
fertilizer blender. Spray nozzles must be positioned to provide uniform coverage of 
Zorial Rapid 80 onto fertilizer during mixing. 
Addition of a drying agent may be necessary if the fertilizer/herbicide blend is too wet 
for uniform application due to high humidity, high urea concentration, and/or low 
fertilizer use rate. Slowly add the drying agent to the blend until a flowable mixture is 
obtained. Drying agents are not recommended for use with on-board systems.

-13-
Apply 200-750 Ibs. of fertilizer/herbicide blend per acre. Application must be made 
uniformly to the soil to prevent possible crop injury and to assure satisfactory weed 
control. Coated fertilizer spread at 112 rate and overlapped to obtain a full rate will 
insure a more uniform distribution. A shallow (1 to 2-inch) incorporation is desirable for 
improved weed control. Deeper incorporation may result in unsatisfactory weed control. 
Formula to determine herbicide used per ton of fertilizer: 
Ibs. of product per acre 
Ibs. of fertilizer per acre 
Geographic Information 
x 2000 = Ibs. of herbicide 
per ton of fertilizer.

If the cotton, peanut, or soybean plant is stressed during early development, application 
of Zorial Rapid 80 at the label rate may result in temporary bleaching or chlorosis of the 
leaves from which the plant will recover. Do not apply in areas with poor drainage. 
Replacement and Rotational Crops 
For 16 months following the last Zorial Rapid 80 application, treated acreage must only 
be rotated to alfalfa, cotton, soybeans, or peanuts. Visual symptoms of injury (loss of 
pigment [whitening] in the leaf veins) and stand reduction may occur in rotational crops 
of soybeans or peanuts in TX (west of 1-35), southwest OK, and NM planted within 16 
months following the last Zorial Rapid 80 application. In AZ, treated acreage must only 
be rotated to cotton. 
Peanuts can be planted as a replacement crop (e.g., following hail damage) 30 days 
after the last Zorial Rapid 80 application. Soybeans can be planted as a replacement 
crop 45 days after the last Zorial Rapid 80 application. In areas of the mid-South,

-16-
Southeast, and TX (east of 1-35), a light reworking of the soil is recommended to 
remove existing plant material and maintain herbicidal activity. Zorial Rapid 80 treated 
acreage may be planted to a cover crop to control soil erosion. Cover crops should be 
plowed under and not grazed or harvested for 16 months following the last application 
of Zorial Rapid 80. Small grain cover crops should be broadcast planted rather than 
drilled to reduce risk of injury. 
If replanting to cotton, peanuts, or soybeans is necessary, a light reworking of the 
topsoil will retain the herbicidal activity of Zorial Rapid 80. In AZ replanting will mean 
irrigating up, so irrigation must be every other furrow. 
SPECIFIC COTTON DIRECTIONS 
Zorial Rapid 80 can be used for weed control in all cotton producing states, except CA. 
The specific Directions for Use of Zorial Rapid 80 are given below for each geographic 
region of use (see Replacement and Rotational Crops for description of geographic

programs: 
1. Do not use in TX (west of 1-35), southwest OK, and NM in conservation tillage 
programs where the soil is greater than 65% sand. 
2. Use a postemergence herbicide, such as Gramoxone or Roundup, prior to 
application of Zorial Rapid 80 or tank mix Zorial Rapid 80 with these products to 
control emerged weeds. 
3. Any cover crop must be killed, using an appropriate postemergence herbicide 
prior to planting. Poor weed control may result if the cover crop is incompletely 
killed or excessive plant debris is present when Zorial Rapid 80 is applied. 
4. Cotton seed should be planted at least 1 inch deep using a planter having a 
bubble or ripple-type coulter with a straight leading edge and press wheel (a 
fluted coulter should not be used). The seed must be covered with at least 1 
inch of soil following the planter press wheel. Avoid situations where water will 
pond over the seed row. Crop injury will occur if seed is not adequately covered 
with soil or water ponds over the seed row.

SPECIFIC PEANUT DIRECTIONS 
Zorial Rapid 80 can be used for weed control in peanuts in the states of AL, FL, GA, 
MS, NC, NM, OK, SC, TX, and VA. 
Zorial Rapid 80 will control certain grass and broad leaf weeds when applied 
preemergence at planting (see the Weeds Controlled section). Only one application 
per crop is allowed in peanuts and this application must be made at planting. Zorial 
Rapid 80 must be applied and incorporated by tillage, irrigation, or rainfall before weeds 
germinate. 
For use only in the states of AL, FL, GA, MS, NC, NM, OK, SC, TX, and VA on runner 
type.or Virginia-type peanut cultivars, including 'Florunner', 'GK-T, 'GA-Runner', 
'Southern Runner', 'NC 1', 'VA 938', 'NC 9', 'NC-V11', 'VA-C 92R', 'AgraTech VC-1', 
and 'NC 1 ~C'. 
Do not use Zorial Rapid 80 iri other states or on spanish peanut cultivars. Crop 
tolerance of cultivars not listed on this label may not be acceptable. 
Rate Selection 
Broadcast Rate 
East of the Mississippi River 
West of the Mississippi River 
1 .5 - 1.8 Ibs. of Zorial Rapid 80 per treated 
acre (Apply preemergence only) 
0.5 lb. of Zorial Rapid 80 per treated acre 
(Apply preemergence only) 
Use the higher recommended rate when Zorial Rapid 80 is used alone or on fine­
textured soils, or where populations of susceptible weeds are very heavy. Use of rates 
higher than 0.5 lb. Zorial Rapid 80 west of the Mississippi River will result in crop injury 
and is not recommended.' 
Apply as a preemergence surface application immediately after planting and before 
weeds or crop emerge. 
Use Precautions 
• Do not use on peanuts that were treated preplant incorporated with Vernam®, as 
crop injury will result. .00 not apply Zorial Rapid 80 when peanuts are near cracking, 
at cracking, or emerged, as crop injury may result. Make only one application per 
year.

-25- ) 
• Crop injury may result from the use of Zorial Rapid 80 following Dual when used on 
very coarse-textured soils, such as sand. 
• Delaying applications. of postemergence herbicides, such as Starfire®, may be 
advisable if severe crop whitening is observed (greater than 50%). 'Do not apply in 
areas with poor drainage. 
Temporary whitening of the peanut leaves may occur. If the peanut plant is not 
stressed by adverse environmental factors or diseases, this· whitening generally 
dissipates within 4-6 weeks after planting. Early season whitening of peanuts from 
Zorial Rapid 80 does not result in significant crop stunting, stand reduction, or yield 
loss, if the plants are not stressed by environmental conditions, improper cultural 
practices, or diseases. High levels of seedling disease, adverse environmental stress, 
or improper application may result in increased levels of crop whitening or injury. 
Sequential Applications/Tank Mixes in Peanuts 
Read and follow all label directions for other herbicides listed below used in either 
sequential applications or as tank mix partners with Zorial Rapid 80 for specific rate 
recommendations, application timing, and precautions. 
Application of Zorial Rapid 80 to freshly tilled soil will give optim~m weed control with 
crop safety. However, if weeds are emerged at the time of application, use a suitable 
burndown agent, such as Starfire (paraquat), to control emerged weeds. The burndown 
herbicide may be applied prior to or tank mixed with the Zorial Rapid 80 treatment. 
Zorial Rapid 80 is especially useful for control of Florida beggarweed when in weed 
control programs that utilize cultivation or both preemergence and postemergence 
herbicides. 
Zorial Rapid 80 can be applied as a sequential overlay treatmentfollowing apreplant 
incorporated application of Balan® OF, Sonalan® HFP, Prowl, or Dual. Do not apply 
Zorial Rapid 80 to peanuts that have been treated with Vernam because of increased 
potential for crop injury. Zorial Rapid 80 tank mixes with Lasso and Dual will increase 
preemergence control of the "difficult to control species," such as Florida beggarweed 
,and yellow nutsedge, and will broaden the spectrum of species controlled. Zorial Rapid 
, 80 may be applied as a preemergence tank mix with Lasso and/or Dual. 
Under most conditions, a burndown application of Starfire (or tank mixes of Starfire and 
Basagran and/or 2,4-DB) applied early postemergence will improve residual control of 
Florida beggarweed obtained with Zorial Rapid 80 by removing Florida beggarweeds 
that germinated or emerged prior to the activation of Zorial Rapid 80. Sequential 
applications of Classic, Pursuit®, and Butoxone® (2,4-DB) may be used following Zorial 
Rapid 80 to control tolerant weeds. .

Do not apply this product through any type of irrigation system. 
Zorial Rapid 80 is only recommended for preemergent weed control in established 
alfalfa; do not apply to seedling alfalfa until it has emerged and been actively growing 
for 5 months. . 
Do not apply Zorial Rapid 80 within 28 days of harvest. 
Soil disturbances, such as rodentburrowing and fire ant mounding, may result in 
temporary bleaching or reduced growth in alfalfa treated with Zorial Rapid 80. 
Do not apply to alfalfa planted with small grain or grass companion cover, unless injury 
to the companion crop is acceptable. Alfalfa seed germinating after Zorial Rapid 80 is 
activated in the soil will not become established. 
Application Timing and Rates 
Zorial Rapid 80 may be applied to healthy stands of established alfalfa at 1.25 Ibs./A; 
do not apply to seedling alfalfa until it has emerged and been actively growing for 5 
months. An additional 1.25 Ibs.lA may be applied later in the first crop year to extend 
late season weed control. . 
Application in each of the following crop years may be made at 1.25-2.5 Ibs./A, 
depending upon weed pressure, soil texture, and cultural practices: 
• Use the lower rate on coarse soils (sand, loamy sand, sandy loam) and when low 
populations of easily controlled annual weeds are expected. 
• Use the higher rate on medium- to fine-textured soils (sandy clay through clay) and­
when heavier weed pressure is expected. The 2.5 lb. maximum annual rate may be 
applied in a single application or in split applications. 
Do not apply more than 2.5 Ibs./A per calendar year. 
Incorporation by rainfall, irrigation, or tillage (for example, by spring tine, disk, or spike 
tooth harrow) is necessary to activate Zorial Rapid 80 in soil before weed seeds 
germinate and emerge. A minimum of 112-1 .inch of rainfall or irrigation is necessary to 
incorporate Zorial Rapid 80.

Application may be made during dormancy, as long as soil is not frozen or in actively 
growing stands. On nondormant alfalfa, application should always follow mowing and 
removal of hay to ensure spray reaches the soil surface. In nonirrigated areas which 
have less than 15 inches annual moisture (rainfall and snow combined) or less than 4 
inches spring rainfall, fall or winter applications are recommended. Fall or winter 
applications are necessary for control of winter annual weeds. 
Zorial Rapid 80 will not control emerged weeds. Established weeds or weeds that 
emerge before activation may be controlled with postemergent herbicides that bear 
labeling for use in the culture of alfalfa. 
Tank Mixes 
Zorial Rapid 80 may be tank mixed with any of the following products that bear labeling 
for use on alfalfa. Read and follow directions for use, precautionary statements, and 
rates of application of these tank mix partners.

Soils with less than 65% sand in AZ and CA and all soils in AL, AR, FL, GA, LA, MS, 
NC, NM, OK, SC, TN, TX and the portions of CO, KS, and MO south of 1-70 treated 
with Zorial Rapid 80 may only be rotated to cotton, soybean, peanut, or asparagus 
within 16 months after application. Soybean and peanut may show pigment loss 
(bleaching in leaf veins) and/or stand reduction in TX (west of 1-35), southwest OK and 
NM if planted within 16 months following the last Zorial Rapid 80 application. 
Soils with 65% sand or more in AZ and CA and all soils in ID, NV, OR, and WA treated 
with Zorial Rapid 80 may only be rotated to cotton, soybean, peanut, or asparagus 
within 16 months with a minimum of two summer periods after application. Additionally, 
intended rotational crops must be bioassayed prior to planting. Rotational crops may
