Nic-lt
TU 
Herbicide is a suspensi6n concentrate used ala rate 2-4 fluid ounces per acre for selective 
postemergence grass weed control in field corn grown for seed or grain, popcorn and sweet corn. 
3

Do not make more than two applications of Nic-It'" Herbicide per cropping season. The combined dosage of 
sequential applications canno~ exceed 4 ounces per acre of Nic-It'" Herbicide. 
WHEN TO APPLY 
Normal Planned! Use , 
Nic-It TN Herbicide may be used on field corn, high Iysin~, waxy, white or other food grade corn hybrids. 
Nic-It'" Herbicide may be broadcast to corn up to 20" tall (free standing) or that is exhibiting up to and 
including 6 leaf collars (V6),yJhichever is more restrictive. 
While Nic-lt
TN 
Herbicide has a~ide application window, research has shown best results are obtained when 
applications are made early Postemergence when corn and weeds are small. Target applications to corn 
that is less than 12" tall for best overall performance. 
Timing to Weeds : 
Apply Nic-lt
lll
Herbicide when grass weeds are young and actively growing, but before they exceed the sizes 
indicated in Table 1. Treat heavy infestations of weeds before they become too competitive with the 
crop, especially where soil moisture and/or fertility are limited. Nic-It no Herbicide provides weed control 
via foliar absorption. Nic-It'" ~erbicide only controls those weeds that have emerged. For later-emerging 
weeds, a second application or a timely cultivation is required. Applications made to weeds larger than 
the size indicated on this lab,el or to weeds under stress may result in unsatisfactory control. Refer 
to LATE OR RESCUE APPLICATIONS. 
LATE OR RESCUE APPLICATIONS 
Nic-It'" Herbicide may be applied to field corn as a rescue treatment for the control of escaped grass weeds, 
or as a directed Postemergence application on corn that is taller than 20" or which has more than 6 collars 
(which ever occurs first). ' 
i 
o For corn 20" to 36" tall, apply Nic-It'" Herbicide with drop nozzles only and avoid spraying into the 
whorl of cornstalks. : ' 
o Do not apply to corn that is taller than 36" or that exhibits 10 or more collars (V10), whichever is most 
restrictive. 
Applications made to weeds larger than those listed on this label may vary from complete control to 
suppression. Level of control ).Viii depend on the weed species, stage of growth, and environmental 
conditions. 
Due to the unplanned nature cif rescue applications, choices must be made between the risks that arise from 
applications made beyond the: proper time for Nic-lt™ Herbicide use, and the effects of season long grass 
weeds competition and/or harVest complications. These choices must balance risks from improperly timed 
Nic-It"" Herbicide use that include, but are not limited to: 
o Yield loss due to competition: Research indicates competition from foxtail exceeding 4 inches in 
height may reduce corn yields. Applications to foxtail and other annual grass weeds that exceed the 
sizes stated on the label increases the risk of yield losses due to prolonged competition with the crop 
even though control rnay be acceptable. Density is more-important than just size. 
o Incomplete control of grass weeds beyond labeled size: Applications to grass weeds that exceed 
the labeled sizes can ~~sult in reduced control. This incomplete control may reduce corn yield. 
o Incomplete grass control due to herbicide stress: Grass weeds under stress from previous herbicide 
applications may not b,e actively growing and susceptible to Nic-It'" Herbicide. This stress may 
reduce grass control in "rescue~ situations. 
o Ear malformation: Applications of Nic-It'" Herbicide on corn that has 7 to 1 0 collars (V7 to V10) 
increases the potential for ear malformation (pinching). This risk may be greatly reduced, but not 
eliminated, by using drop nozzles properly adjusted so as to not apply Nic-It'" Herbicide into the corn 
whorl. ' 
4

RATE 
Optimum control of the weeds; listed can be achieved with 2 ounces of Nic-It'" Herbicide. Weeds that exceed 
the listed weed sizes by up to '50% may be partially controlled with rates between 2 to 4 fluid ounces of Nic-
It'" Herbicide per acre. : 
As weeds mature, their sensitivity to Nic-It no Herbicide decreases. As grass weeds become mature 
(more than 3 tillers), they may not reach the size listed below, due to drought or other environmental 
factors. Grass weeds that are maturing rapidly should be treated before they reach the stages listed 
below. ' 
When applied as directed, Nic~Jt"" Herbicide will control the following weeds:

Popcorn, Field Corn Grown for Seed and Sweet Corn 
Nic-It TW Herbicide may be broadcast or applied with drop nozzles to popcorn or field com grown for seed that 
is less than 20" tall (free-standing) or that exhibits up to and including S leaf-collars (VS), whichever is most 
restrictive. Do not apply to corn that is taller than 20" or that exhibits more than S leaf-collars (VS), whichever 
is more restrictive. 
Many seed companies have tested seed corn inbreds or yellow p~corn hybrids for sensitivity to Nic-It 
Herbicide and have reported excellent safety. Do not apply Nic-It Herbicide to any white popcorn inbred, or 
white popcorn hybrid unless specifically approved by the seed company. This includes "White Dynamite" 
popcorn. 
Nic-It'" Herbicide may be applied to certain sweet corn hybrids grown for fresh markets or under contract for 
processing. Applications of Nic-lt
TW 
Herbicide may be applied broadcast or with drop nozzles (post-directed) 
on sweet corn up to 12 inches tall or up to and including Sleaf-collars (VS). For sweet corn 12-18 inches tall, 
apply only with drop nozzles. Do not apply to sweet corn taller than 18 inches or those which exhibit 6 or 
more leaf-collars (v6), and ma.ke only one application of Nic-It Herbicide per year. 
Sweet corn hybrid sensitivity to Nic-It'" Herbicide is highly variable, and not all hybrids have been tested for 
crop tolerance. 
Not all seed corn inbreds, pop'corn or sweet corn hybrids have been tested, nor does Cheminova have 
access to all seed company data. Consequently, Cheminova is not responsible for any crop injury arising 
from the use of Nic-It'" Herbicide on field corn for seed, popcorn or sweet corn. When tank mixing, check the 
tank mix partner label for tolerances and instructions for use. 
See Soil Insecticide Interaction Information regarding the use of Nic-It ..... Herbicide on popcorn, sweet corn 
or field corn grown for seed that has been previously treated with a soil insecticide. 
SPRAY ADJUVANTS 
Applications of Nic-It'" Herbicide must include either a crop oil concentrate or a nonionic surfactant. In 
addition, an ammonium nitrogen fertilizer must be used unless specifically prohibited by tank mix partner 
labeling. Crop oil concentrate plus ammonium nitrogen fertilizer is tlie preferred adjuvant system for activity 
on difficult to control species such as woolly cupgrass, quackgrass, sand bur and wirestem mUhly. If another 
herbicide is tank mixed with Nic-It'" Herbicide, select adjuvants authorized for use with both products. 
Products must contain only EPA-exempt ingredients (40 CFR 1001). 
Crop Oil Concentrate (COC).:... Petroleum or Modified Seed Oil (MSO) 
o Apply at 1% v/v (1 gallon per 100 gallons spray solution) or 2% under arid conditions. MSO 
adjuvants may be used at O.S% v/v if specified on local Cheminova product literature or service 
policies. 
o MSO adjuvants may be used at O.S% v/v (O.S gallons per 100 gallons spray solution) if specifically 
noted on adjuvant product labeling. 
6

o Oil adjuvants must contain at least 80% high quality; petroleum (mineral) or modified vegetable seed 
oil with at least 15% surfactant emulsifiers. ' 
Nonionic Surfactant (NIS) 
o Apply at 0.25% v/v (t,quart per 100 gallons spray solution) or 0.5% under arid conditions. 
o Surfactant products must contain at least 60% non ionic surfactant with a hydr'ophilic/lipophilic 
balance (HLB) greater than 12. 
Ammonium Nitrogen Fertilizer 
o Use 2 quarts/acre of a high-quality urea ammonium nitrate (UAN), such as 28%N or 32%N, or 2 
pounds/acre of a spray-grade ammonium sulfate (AMS). Use 4 quarts/acre UAN or 4 pounds/acre 
AMS under arid conditions. 
o Do not use liquid nitrogen fertilizer as the total carrier solution. 
Special Adjuvant Types 
o Combination adjuvanfproducts may be used at doses that provide the required amount of NIS, 
COC, MSO and/or ammonium nitrogen fertilizer. Consult product literature for use rates and 
restrictions. 
MIXING INSTRUCTIONS 
1. Fill a thoroughly clean spray tank % to 213 full of water. 
2. While agitating, add directly from the container the required amount of Nic-It'" Herbicide. , 
3. Continue agitation anq when the spray tank is 90 % full add the required spray adjuvants (crop oil 
concentrate, nonionic,surfactant, or ammonium nitrogen fertilizer). 
4. When this product mix is thoroughly suspended, finish filling the ~ray tank. 
5. Maintain continuous agitation throughput the application of Nic-It Herbicide. 
6. Apply Nic-It'" Herbicide spray mixture within 24 hours of mixing to avoid product degradation. 
TANK MIX APPLICATIONS 
For additional Control of Broadleaf Weeds 
Nic-It'" Herbicide may be tank'mixed with many herbicides registered for postemergence application in corn 
for additional control of broadleaf weeds. See the tank mix partner label for weeds controlled, precautions, 
use restrictions, adjuvant and :crop rotation information. The most restrictive language on either label shall 
apply. Applications offull or reduced 'rates of other products registered for use in corn provided: 
o The tank mix product is labeled for the same timing, method of application, adjuvants, and use 
restrictions as Nic-It Herbicide. 
o The tank mixture is not specifically prohibited on the label of the tank mix product. 
o The tank mix combin9tion is compatible as determined by a "jar test" described in the TANK MIX 
COMPATIBILITY TESTING section below. 
Crop oil concentrate plus ammonium nitrogen fertilizer is the preferred adjuvant for tank mixtures when using 
products at the low end of the rate range indicated in the table. The use of the nonionic surfactant is 
permitted in place of crop oil concentrate for tank mixtures containing dicamba, however, overall weed 
control may be reduced. See SPRAY ADJUVANTS for adjuvant rate recommendation. 
Do not use MSO adjuvants when tank mixing Nic-It'" Herbicide with >1.5 ounces "Callisto." 
For Additional Control of Later Emerging Grasses . . 
Nic-It'" Herbicide may be t~nk:mixed with full or reduced rates of pr~emergence grass herbicides labeled for 
early postemergence application to field corn such as DuPont™ CINCH®, CINCH® ATZ, "Prowl," "Surpass" 
EC, "Dual" II Magnum, or "Outlook") for residual activity on later~emerging flushes of grass. Application must 
be made before the grass emerges and before other grass weeds on the Nic-It'" Herbicide label exceed their 
labeled sizes. 
7

The use of nonionic surfactant is recommended in place of crop oil concentrate for tank mixtures with 
preemergence grass herbicides where applications are made early postemergence to small grass weeds. 
See SPRAY ADJUVANTS for:adjuvant rate recommendations. 
When tank mixing Nic-lt'""He~bicide with EC formulated preemergence grass herbicides such as DuPont™ 
CINCH®, "Dual" II Magnum, or "Prowl: do not add "Callisto" herbicide to the tank mixture. When other 
formulations of preemergence grass herbicides are tank mixed with Nicosulfuron + "Callisto" (such as 
CINCH® ATZ or "Bicep II Magnum"), limit preemergence herbicide rates to 2/3 times full rates, always add 
nonionic surfactant in place of crop oil concentrate, and limit broadleaf weed sizes to less than or equal to 4" 
tall. 
When tank mixing Nic-It'" Herbicide with "Lumax" herbicide, limit "Lumax" rates to no more than 2 pints, 
always add non ionic surfactant in place of crop oil concentrate, omit adjuvants containing ammonium 
nitrogen fertilizer, and limit applications to corn up to 5" tall. 
Tank mixes of Nic-It'" Herbicide and preemergence grass herbicides must be broadcast applied 
postemergence to field corn before the crop exceeds the heights'listed on the preemergEmce grass herbicide 
label. Refer to WHEN TO APPLY - POSTEMERGENCE and the preemergence grass herbicide label for 
complete postemergence application information, rates, and restrictions. 
Tank Mixtures with Insecticides 
Nic-It'" Herbicide may be tat:l~;mixed with pyrethoid or carbamate ins~cticides such as DuPont™ ASANA® 
XL or DuPonFM LANNATE® insecticides. See Soil Insecticide Interaction section for information on use of 
Nic-It Herbicide following soil insecticides application. 
Other Tank Mixtures 
Other than the exceptions noted, and in addition to the tank mix partners and rates indicated above, Nic-It '" 
Herbicide may be tank mixed or followed with sequential applications of other products registered for use in 
field com. Applications of full 'or reduced rates of other products registered for use in corn provided: 
o The tank mix product is labeled for the same timing, method of application, adjuvants, and use 
,restrictions as Nic-lt"'Herbicide. 
o The tank mixture is not specifically prohibited on the label of the tank mix product. 
o The tank mix combination is compatible as determined by a "jar tesf' described in the TANK MIX 
COMPATIBILITY TESTING section below. 
Weed control and crop response with tank mixtures that are not specifically recommended in this label are 
the responsibility of the user and manufacturer of the tank mix product. 
Tank Mixing Precautions: 
A corn plant's predisposition t() develop fused tissue emerging from the whorl (rattail) after the V-11 stage 
may increase when a product containing dicamba (Le., "Clarity," "Marksman") is applied to small corn under 
early stressful conditions. Be ~ware of this when applying tank mixes with dicamba to small corn (V-3 stage 
or smaller) under stressful conditions. See ENVIRONMENTAL CONDITIONS for a description of these 
stressful conditions. 
To avoid crop injury or antago[1ism, apply the products indicated below at least seven days before or three 
days after the application of Nit-It'" Herbicide. , 
o Do not tank mix Nic-It'" Herbicide with "Basagran" and "Laddok" or severe crop injury may occur. 
o Do not tank mix Nic-It'" Herbicide with 2,4-0 containing products as severe grass control antagonism 
may occur. 
o Do not tank mix Nic-It"" Herbicide with foliar-applied organophosphate insecticides such as 
8

"Lorsban," "Nufos," malathion, parathion, etc., as severe crop injury may occur. 
Do not exceed labeled application rates. Do not tank mix Nic-It'" Herbicide with other products that contain 
the same active ingredients as Nic-It'" Herbicide (nicosulfuron) unless the label of either tank mix partner 
specifies the maximum rate that may be used. 
TANK MIX COMPATIBILITY TESTING 
Perform a jar test prior to tank :mixing to ensure compatibility of Nic-It'" Herbicide and other pesticides. Use a 
clear glass quart jar with lid and mix the tank mix ingredients with their relative proportions. Invert the jar 
containing the mixture several;times and observe the mixture for approximately % hour. If the mixture balls­
up, forms flakes, sludges, gels,' oily films or layers, or other precipitates, it is not compatible and the tank mix 
combination should not be used.' 
SEQUENTIAL NIC-IT'" H'ERBICIDE APPLICATIONS 
Annual grass weeds may have. more than one flush of emerging seedlings. Also, regrowth of treated annual 
grass weeds may occur due to .adverse environmental conditions follOwing application .. Perennial grass 
weeds may regrow from undetground stems or roots, depending upon environmental conditions . .To control 
grass weeds under these conqitions, a sequential application of Nic-It'" Herbicide may be necessary. The 
combined dosage ofthe sequehtial applications cannot exceed 8 fluid ounces-per acre of Nic-It'" Herbicide. 
CULTIVATION 
A timely cultivation may be necessary to control suppressed weeds, or weeds that emerge after an 
application of Nicosulfuron. . 
Optimum timing for cultivation is 7-14 days after Nic-lt™ Herbicide application or upon seeing the 
establishment of new weeds. 
ENVIRONMENTAL CONDITIONS AND 
BIOLOGICAL ACTIVITY 
Nic-It'" Herbicide provides best results when applied to young, actively growing weeds. Applications made 
during warm, moist conditions (70°F or more) and adequate soil moisture both before and after application 
maximizes performance. 
The degree and duration of control depend on spray coverage, weed spectrum, weed size, growing 
conditions before and after treatment, soil moisture, and adjuvant selection. 
Nic-It'" Herbicide is rainfast in 4 hours. 
Treating weeds that exceed maximum label height or that are under stress may result in incomplete control. 
Poor weed control or crop injury may result from applications made to plants under stress from: 
o abnormally hot or cold weather 
o environmental conditions such as drought, water-saturated soils, hail dam~ge, or frost 
o disease, insect or nematode injury 
o prior herbicide, or carryover from a previous year's herbicide application 
Severe stress from conditions preceding or immediately following application may also result in crop injury or 
poor weed control. Stress affects all weeds, but especially weeds such as woolly cupgrass, green and 
yellow foxtail, and wild proso millet. ' 
If the corn or grass weeds are under stress, delay application until stress passes and both weeds and corn 
resume active. growth. 
Nic-It'" Herbicide rapidly inhibits the growth of susceptible weeds, reducing weed competition within as little 
as 6 hours after application. Susceptible plants are controlled in 7-21 days.

SOIL INSECTICIDE INTERACTION INFORMATION 
Before using Nic-It'" Herbicide, ensure that it is compatible with any insecticides previously applied to the 
corn crop. ' 
Nic-It'" Herbicide may interact;with certain insecticides previously applied to the crop. Crop response varies 
with field corn type, insecticid~'used, insecticide application method, and soil type. 
Nic-It'" Herbicide may be applied to corn previously treated with "Fortress," "Aztec," or "Force" insecticides or 
non-organophosphate (OP) soil insecticides regardless of soil type. 
" DO NOT APPLY Nic-It''' Herbicide to corn previously treated with "Counter" 15G or to-corn treated 
with "Counter" 20CR in-furrow or over the row at cultivation. 
" - Applications of Nic-It"<Herbicide to corn previously treated with "Counter" 20CR, "Lorsban," "Nufos," 
or "Thimet" may caus~unacceptable crop injury, especially on soils of less than 4% organic matter. 
CROP ROTATION , 
Rotational crops vary in their r~sponse to low concentrations of Nic-It'" Herbicide remaining in the soil. Nic­
It'" Herbicide dissipates rapidltin warm, acidic, microbiologically active soils. 
The amount of Nic-It'" Herbicide which may be present in the soil depends on application rate, soil pH and 
organic matter content, elapsed time since application, crop production practices, and environmental factors. 
Injury to rotational crops mayo~cur in high-pH, cold soils if dry weather prevails between applications and 
rotational crop planting. ' 
Soil pH should be determined by laboratory analysis using the 1:1 soil:water suspension method on 
representative soil samples taken at 0-4" depth. Soil pH varies within fields; therefore, recropping should be 
based on the highest soil pH within each field. Consult local extension publications for recommended soil 
sampling procedures. 
The following rotational intervals should be observed when using Nic-It'" Herbicide at a maximum of 4 fluid 
ounces:

APPLICATION INFORMATION 
Many crops are highly sensitive to Nic-ltTN Herbicide. All direct or indirect contact (such as spray drift) with 
crops other than field corn should be avoided (see also SPRAY DRIFT MANAGEMENT). 
For all application systems, use 50-mesh or larger strainer screens. 
Do not apply Nic-it'" Herbicide through any type of irrigation system. 
GROUND APPLICATION, 
Broadcast Application 
o Use a minimum of 15 gallons of water per acre (15 GPA) for best performance. Use a minimum of 
10 gallons of water pe(acre (GPA) for light. 
o For best performance, select nozzles and pressure that deliver MEDIUM spray droplets, for 
example, as indicated if) nozzle manufacturer's catalogues and in accordance with ASAE Standard 
11

S572. Nozzles that d~liver COARSE spray droplets may be used to reduce drift, provided spray 
volume is increased t6 maintain coverage on small weeds. For optimal product performance and 
minimal spray drift, adjust the spray boom to the lowest possible spray height recommended in 
manufacturer's specifications. 
o Ensure that equipme~t is set up to avoid applying an excessive rate directly over the rows and into 
the com plant whorl. This is most likely to occur when a nozzle is positioned directly above the row. 
Q Overlaps or starting, s:topping, slowing, and turning while spraying may result in crop injury. 
Band Application 
For band applications, use pr~portionately less spray mixture, and carefully calibrate the band applicator to 
not exceed the labeled rate. Carefully follow the manufacturer's instructions for nozzle type (flat fans), 
orientation, distance of nozzles from the crop and weeds, spray volumes, calibration and spray pressure. 
AERIAL APPLICATION i 
In New York State and Califor6ia, aerial application is not permitted. 
Use nozzle types and arrangements that will provide optimum spray distribution and maximum coverage at a 
minimum of 3 GPA. . 
Do not apply during a temperature inversion, when winds are gusty, or when conditions favor poor coverage 
and/or off-target spray movem~nt. 
SPRAYER PREPARATION/CLEANUP 
It is important that spray equiphlent is clean and free of previous pesticide deposits before using Nic-It'" 
Herbicide and then properly cleaned out following application. Clean all application equipment before 
applying Nic-It'" Herbicide. Follow the cleanup procedures specified on the label of the product previously 
sprayed. If no cleanup procedure is provided, use the procedure that follows. Immediately following 
applications of Nic-It'" Herbicide, thoroughly clean all mixing and spray equipment to avoid subsequent crop 
injury. 
Note: 
, . . 
o When cleaning spray equipment before applying Nic-It'" Herbicide, read and follow label directions 
for proper rinsate disposal ofthe product previously sprayed. . 
o Steam cleaning of aerial spray tanks will help to dislodge any visible pesticide deposits. 
Q When spraying or mixing equipment will be used over an extended period to apply multiple loads of 
Nic-It'" Herbicide, partially fill the tank with fresh water at the end of each day of spraying, flush the 
boom and hoses, and allow to sit overnight. 
Cleanup Procedure 
1. Drain the tank and thof9ughly hose 'down the interior surfaces. Flush the tank, hoses, and boom 
with clean water for a minimum of 5 minutes. 
2. Partially fill the tank with clean water and add one gallon of household ammonia* (containing 3% 
active) for every 100 gallons of water. Finishfillirig the tank with water, then flush the cleaning 
solution through the hoses, boom, and nozzles. Add more water to completely fill the tank and allow 
to agitatelrecirculate for. at least 15 minutes. Again, flush the hoses, boom, and nozzles with the 
cleaning solution, then drain the tank. 
3. Repeat step 2. 
4. Remove the nozzles and screens and clean separately in a bucket containing the cleaning agent 
12

and water. 
5. Thoroughly rinse the t~nk with clean water for a minimum of 5 minutes, flushing the water through 
the hoses and boom. 
SPRAY DRIFT MANAGEMENT 
The interaction of many equip~ent and weather-related factors determines 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 redu~e drift potential is to apply large droplets (>150-200 microns). 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 
o Volume - Use high flow rate nozzles to apply the highest practiCal spray volume. Nozzles with 
higher rated flows produce larger droplets. 
o Pressure - Use the 10\(\ler spray pressures recommended for the ,nozzle. Higher pressure reduces 
droplet size and does,notimp,rove canopy penetration. WHEN HIGHER FLOW RATES ARE' 
NEEDED, USE A HIGHER-CAPACITY NOZZLE INSTEAD OF INCREASING PRESSURE. 
o Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle 
types, narrower spray flngles produce larger droplets. Consider using low-drift nozzles. 
Controlling Droplet Size - Aircraft 
o Number of Nozzles -Use the minimum number of nozzles with the highest flow rate that provide 
uniform coverage. 
o Nozzle Orientation -Orienting nozzles so that the spray is emitted backwards, parallel to the 
airstream will produce larger droplets than other orientations. 
o Nozzle Type - Solid stream nozzles (such as disc and core with swirl plate removed) oriented 
straight back produce I~rger droplets than other nozzle types. 
o Boom Length - The boom length should not exceed % of the wing or rotor length - longer booms 
increase drift potential. 
o 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 an,d wind. For ground equipment, the boom should remain level with the 
crop and have minimal bounce, 
WIND I 
Drift potential increases at wind speeds of less than 3 mph (due to inversion potential) or more than 10 mph. 
However, many factors, including droplet size and equipml9nt 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. . 
13

TEMPREATURE INVERSIONS 
Drift potential 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 ana 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 ~nd 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. 
SHIELDED SPRAYERS . 
Shielding the boom or individu~1 nozzles can reduce the effects of wind. However, it is the responsibility of 
the applicator to verify that the shields are preventing drift and not interfering with uniform deposition of the 
product.· 
INTEGRATED PEST MANAGEMENT 
This product may be used as p~rt of an Integrated Pest Management (IPM) program thalcan include 
biological, cultural, 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 
monitoring, and treating when target pest populations reach locally determined action thresholds. Consult 
your state cooperative extension service, professional conSUltants or other qualified authorities to determirie 
appropriate action treatment threshold levels for treating specific pest/crop systems in your area. 
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 ~ product affecting a different site of action. 
To better manage herbicide resistance through delaying the proliferation and possible dominance of 
herbicide resistant 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 resi~tant biotypes. Consult you agricultural dealer, consultant, applicator, and/or 
appropriate state agricultural ex,tem;ion service representative for specific alternative cultural practices or 
herbicide recommendations available in your area. 
IMPORTANT PRECAUTIONS 
Injury or loss of desirable vegetation may result from failure to observe the following: 
.. Do not apply Nic-lt™ Herbicide or drain or flush application equipment on or near desirable trees or 
other plants, or on areCls where their roots may extend, or in locations where the chemical may be 
washed or moved into ¢ontact with their roots. 
.. Do not use on lawns, walks, driveways, tennis courts, or similar areas. 
o Prevent drift of spray tc)desirable plants. 
o Do not contaminate any body of water. 
o Thoroughly clean application equipment immediately after use. (See the Sprayer Cleanup section of 
this label for instructions.) 
o Do not graze or feed forage, hay, or straw from treated areas to livestock within 30 days of Nic-It'" 
Herbicide application. .
