Users should remove PPE immediately after handling this product. As soon as possible, wash thoroughly and change into clean 

clothina. Wash the outside of Qloves before removinQ. 

ENVIRONMENTAL HAZARDS 

Do not apply directly to water, or to areas where surface waler is present or to intertidal areas below the mean high water mark. Do 

not contaminate water when disposing of equipment washwaters. Do not contaminate waler used for irrigation or domestic purposes. 

Avoid spray drift to nearby crops as this product will cause modifications in planl growth. Plant injury or reduced yields may result. 

IMPORTANT: Do not use this producl for purposes other than those listed on the labet. 

SPRAY DRIFT 

Avoid spray drift. Do not apply when wealher conditions may cause drift. Do not allow this product to drift on to non·target areas. Drift 

lfIIifay result in itlegal residues or iniury to adjacent crops and vegetation, in the form of leaf yellowing and defoliation. To avoid spray 

_~ift. DO NOT apply aerially when wind speed is greater than to mph or during periods of temperature inversions. Use of larger 

droplet size witt also reduce spray drift. 

AVOIDING SPRAY DRIFT ATTHE APPLICATION SITE IS THE RESPONSIBILITY OF THE APPLICATOR. 

The interaction of many equipment·and-weatheNelated factors determine Ihe polential for spray drift. The applicalor is responsible for 

considering alt these factors when making decisions. 

The following drift management requirements must be followed to avoid off·target movement from aerial appltcations to agricultural 

field crops. These requirements do not apply to forestry applications. public health uses or to applications using dry formulations. 

\. The distance of the outer most nozzles on the boom must not exceed 314 the length of the wingspan or rolor. 

2. Nozzles must always point backward paraltel with the air stream and never be pointed downwards 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 betow: 

AERIAL DRIFT REDUCTION ADVISORY 

[This section is advisory in nature arid does not supersede the mandatory label requirementsj. 

tNFORMATtON ON DROPLET SIZE 

ahe most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to apply the largest 

Wroplets that provide sufficient coverage and control. Applying larger droplels 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 raled flows produce larger 

droplels. 

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 ftow rate nozzles inslead 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 paraltel to the airstream produces larger droplets Ihan other 

orientations and is the recommonded practice. SignifICant denection from horizonlal witt reduce droplet size and increase drift 

potenliat. 

Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle types, narrower spray angtes produce 

larger droplets. Consider using tow·drift nozzles. Solid stream nozzles oriented straight back produce Ihe largest droplets and the 

lowest drift. 

BOOM LENGTH 

For some use patterns, reducing the effective boom length to less than 3/4 of the wingspan or rolor length may further reduce drift 

without reducing swath width. 

APPLICATION HEIGHT 

Applications should not be made at a height greater than to feet above the top of the target planls unless a grealer height is required 

for aircraft safety. Making applications at the lowest helghtthat is safe reduces exposure of droplets to evaporation and wind. 

2 

11 
SWATH ADJUSTMENT 

When applications are made with a crosswind, the swath wHi be displaced downwind. Therefore, on Ihe up and downwind edges of 

the field, the applicator should compensate for this displacement by adjusting the path of the aircraft upwind. Swath adiuslmenl 

distance should Increase. with increasing drift potential (higher wind, smaller drops, etc.), 

WIND 

Drift potential is lowest between wind speeds of 2 • to mph. However, many factors, including droplet size and equipment type 

delennine drift potential al any given speed. Application should be avoided below 2 mph due to variable wind direction and high 

Inversion potential. NOTE: local terrain can influenC0 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 tNVERSIONS 

Apptications 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 tight variabte 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 atso be identified by 

•

e movement of smoke from a ground source or an aircraft smoke generator. Smoke that layers and moves laterally in a 

oncentrated ctoud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidty dissipates 

indicates good vertical air mixing. 

SENSlTtVE AREAS 

The pesticide should onty 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, non-target crops) is minimal (e.g. when wind is blowing away from the sensjlive 

areas). 

GENERAL INFORMATION 

CERONE® brand Ethephon Ptant Regulator is intended for use as a lodging reduction agent in barley and wheat crops and in grasses 

grown for seed production. Use CERON~ only on vigorously growing crops that are tikely to lodge. Do not use CERONE® tn nontodging situations or where lodgtng causes onty mtntmat ylotd toss. 

Lodged crops increase harvest costs and decrease harvest efficiency and recoverable yields. Lodging can cause uneven maturity. 

higher moisture content and toss of grain quatity. tn grasses grown for seed lodging at anthesls can reduce seed set and yield. 

CERONE® brand Ethephon Plant Regulator decomposes in the plant to release ethylene. a naturally occurring plant hormone. 

CERONE® increases stem strength thereby increasing the plant's reststance to lodging. CERONt0 may shorten the plant depending 

an variety. environmental conditions and the rate used. CERONE® atso reduces HneckingH in barley and yield decreases due to 

...... nattering and head loss.

Avoid spray drill 10 nearby crops as this product win cause modi!ications in plant growth. Plant iniury or reduced yields may resutt. 

IMPORTANT: Do no! use this product for purposes other than those listed on the label. 

SPRAY DRIFT 

Avoid spray drift. Do no! apply when weather conditions may cause drill. Do not aUow this product to ddU on to non-target areas. Dril! 

may result in iltega! residues or iniury to adjacent crops and vegetation, in the lorm 01 !eal ye!!owing and defoliation. To avoid spray 

drift, DO NOT apply aerially when wind speed 15 greater than 10 mph or during periods 01 temperature inversions. Use 01 larger droptet 

size will also reduce spray drifl. 

•

AVOID!NG SPRAY DRIFT AT THE APPLlCAT!ON S!TE !S THE RESPONSIBILITY OF THE APPLICATOR. 

rhe interaction o! many equipment-and-weather-rela!ed lactors determine the potential tor spray drilL The applicator is responsible tor 

considering all these lactors when making decisions. 

The !ollowing drift management requirements must be lollowed to avoid oil-target movement from aerial app!Jca!ions to agricultura! !ield 

crops. These requirements do not apply to lorestry applications, publiC health uses or to applications using dry lormutetions. 

t. The distance 01 the outer most nozzles on the boom must not exceed 3/4 the tength of the wingspan or rotor. 

2. Nozztes must always point backward parallel with the air stream and never be pointed downwards more than 45 degrees. 

Where states have more stringent regulations, they should be observed. 

The apptlcator should be lam!!iar with and take into account the inlormation covered in the Aerial Drift Reduction Advisory below: 

AERIAL DRIFT REDUCTION ADVISORY 

[This section js advisory in nature and does not supersede the mandatory labe! requiremen!sJ. 

!NFORMAT!ON ON DROPLET SIZE 

The most effective way to reduce drilt polenlia! is to apply large droplets. The best drilt management strategy is to apply the largest 

droplets that provide su!l!cient coverage and contro!. Applying larger droplets reduces drift potentia!, but will not prevent drift it 

applications are made improperly, or under un!avorable environmentat conditions (See Wind, Temperature and Humidity, and 

Temperature Inversions). 

flIt:ONTROLL!NG DROPLET SIZE 

Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated nows produce targer 

droplets. 

Pressure' Do not exceed the nozzle manulacturer's recommended pressures. For many nozzle types tower pressure produces larger 

droplets. When higher now ra!e5 are needed, use higher now rate nozzles instead o! increasing pressure, 

Number of nozzles - Use the minimum number 01 nozzles that provide unilorm coverage. 

NOlZlo 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 

Nozz!e Type - Use a nozzle type that is designed lor the intended application. With most noale types, narrower spray angles produce 

targer droplets. Consider usIng low-drift nozzles. Solid stream nozzles oriented straight back produce the targest droptets and the 

towest drifL 

BOOM LENGTH 

•••• 

• •••• 

For some use patterns, redUCing the e!lective boom length to less lhan 3/4 01 the wingspan or roCr·~1'lQ!h may tutther reduce driB 

without reducing 5wath width. • • : ••• : • 

APPLICATION HEIGHT •• : •• : • •• •••• 

Applications should not be made a! a height greater than 10 leet above the top of the target plants~ a greater h"AJht is required 

tor aircralt salety. Making applications a! 1he lowest height that is sate reduces exposure 01 drop!et!i l¢O,¥,i1poration 3f'd wind. 

• •• •• • •••• 

• •• • 

• • •• 

58 
SWATH ADJUSTMENT 

When applications are made with a crosswind, the swath will be displaced downwind. Therelore, on the up and downwind edges of the 

field. the applicator should compensate for this displacement by adjusting the path 01 the aircraft upwind. Swath adjustment distance 

should increase, with increasing drift potential (higher wind, smalter drops, etc.). 

WIND 

Drill potential Is lowest between wind speeds of 2 - to mph. However, many factors, including droplet size and equipment type 

determine drift potential at any given speed. Application should be avoided below 2 mph due to variable wind direction and high 

inversion potential. NOTE: Local terrain can inUuence wind patterns. Every applicator should be familiar with tocalwind pattems and 

how they affect spray drill. 

TEMPERATURE AND HUMID tTY 

When making applications in low retative humidity. sot up equipment to produce larger droplets to compensate lor evaporation. Droptet 

evaporation is most severe when conditions are both hot and dry. 

TEMPERATURE INVERSIONS 

Applications shoutd not occur during a temperature inversion because drill potential is high. Temperature inversions restrict verticat air 

mixing, which causes sma!! suspended droplets to rema'ln 'In a concentrated cloud. This cloud can move in unpredictable directions due 

10 the tight variable winds common during inversions. Temperature inversions are characterized by increasing temperatures with 

a!l1tude and are common on nights with timited ctoud cover and light to no wind. They begin to lorm as the sun sets and olten continue 

into the moming. Their presence can be indicated by ground log: however, il log is not present, inversions can also be identilied by the 

movement ot smoke Irom a ground source or an aircratl smoke generator, Smoke that layers and moves taterally in a concentrated 

e el.OUd, (.under low wind conditions) indicates an inversion. white smoke that moves upward and rapidty dissipates indicates good vertical 

air mo:mg. 

SENStTtVE AREAS 

The pesticide should onty be applied when the potentiat lor drift to adjacent sensitive areas (e.g. residential areas. bodies ot water, 

known habitat tor threatened or endangored species, non-target crops) is minimal (e.g. when wind is btowing away trom the sensitive 

areas). 

GENERAL INFORMATION 

CERONE1': brand Ethephon Plant Regulator is intended lor use as a todging reduction agent in bartey and wheat crops and in grasses 

grown tor seed production. Use CERONE* only on vigorously growing crops that are likety to lodge. 00 not use CERONE'" in 

non·lodgtng situations or where todglng causes only mtnimal yield 10$$, 

lodged crops increase harvest costs and decrease harvest elticiency and recoverable yields. lodging can cause uneven maturity. 

higher moisture content and toss 01 grain quality. In grasses grown lor seed lodging at anthesis can reduce seed set and yield. 

CERONE"" brand Ethephon Plant Regulator decomposes, in the plant to retease ethylene, a naturally occurring ptant hormone. 

CERONE}; increases stem strength thereby increasing the plant's resistance to lodging. CERONE!- may shorten the plant depending 

on variety, environmental conditions and the rate used. CERONE'! also reduces "necking" in barley and yield decreases due to 

shattering and head toss .

SPRAY DRIFT 

Avoid sptay drift. Do not apply whon weather conditions may cause drift. 00 not allow this product to drift on to non·target areas. Drift 

may result in illegal residues or Injury to adjacent crops and vegetation. In the form of leaf yellowing and defo~ation. To avoJd spray 

drift, 00 NOT apply aerially whGn wind speed is greaterihan 10 mph or during pclriods of temperature inversions. Us. of largar dropHrt

AVOIDING SPRAY DRIFT ATlHE APPLlCATION SITE IS ll-IE RESPONSIBtuTYOF lHE APPlICATOR. 

The interaction of many equipment-aod·weather·rolatGd factors detormine the potontial for spl'sy drifl. The applicator is responsible for 

considering allthaso fadors when making docisiont. 

The following drift management requirements must be folklwocl to avoid off-targot movement from aerial applications to agricultural fiekl 

crops. Thosa requiremenU do not apply to forulty appIjcations, public health uses or to applications using dry formulations. 

t. The distance of tho outor moll fXlZ2iea on the boom must not eXceed 314 tho Iongth of the wingspan or rotor. 

2. Nozzle, must a/Wo'p point backward parallel with tho air stream and nGVGt' be pointed downwards mora than 45 dogr ..... 

Wher. states have more stringent regulations, they should be obMrIed. 

The applicator should be familiar with and take into account the Imonnation covered In tho Aerial Drift Reduction AtMao1y below:

{This soction is advisory in nature and doGs not suporsodo the mandatory label requiremonts]. 

fNFORMA nON ON DROPLET SIZE 

The most effective wfl'/ to roduco drift potential Is to apply larga droplats. Tho beat drift managomGnt strategy is to apply tha targest 

droplets that provide suffk:lant coveraga and control. ApfHylng farger dropWs raducH drift potontial, but wi» not prevant drift if 

applications are made improperly, or under unfavorablo anvironmental conditions (Soo Wind, Tomporature DJld Humidity, and 

T empafllture Inversions). 

CONTROlUNG DROPLET SfZE 

Volume - Use high llow rata nozzles to apply the highast practical spray volume. Nozzles with higher rated fiows produce larger 

droplets. 

Pressure· Do not eXceed the nozzle manuiac1urer's roc:ommooded pressuros. For many nozzle typos lower prassure produces larger 

droplets. When high« flow rates are needed, U58 high&( flow rate nozzles instead of Increasing plessura. 

Number of nozzles" U .. too minimum numbol' of nozzles that provide unifonn coverage. 

Nozzle Orientation· Orienting nozzles so that the spray is released parallel to the airstream produces larger droplets than other 

orientations and is the rocommondad practice. Significant deffGCtion from horizontal will reduce droplet size and incroase drif1 

potontiaL •••••• 

Nozzle Typo· Usa a noule type that is designed for thelntendGd application. With most nozzle types, narro'l/M""s1>fay anglu produce

Whon applications are made with a croS!lwinci, tho swath will be displaced downwind. Thorolor •• on tho up and downwind edges of tho 

fiold, tho applicator should compensate lor Ihis displacomanl by adjusting tho path altho aircraft upwind. Swath adjustmont distanco 

should increase, with incroasing drift potontial (higher wind, smallor drops, Gte.). 

WIND 

Drift potential is lowest between wind spoods 012 - to mph. Howevor. many factors, including droplot size and oquipmonllypo 

dotermine drift potential at any given spGod. Application should be avoided below 2 mph duo to variable wind diroction and high 

inversion potential. NOTE: local terrain can inUuanee wind pattems. Evory applicator should be lamiliar with local wind pattorns arw:l 

how they affect spray drift. 

TEMPERATURE AND HUMIDITY 

Whon making applications in bw rolativo humidity. sal up equipmont to produce largor droplats to rompom~alo lor evaporaten. Droplot 

aV<ijXJration is most severe when condkions are both hot and dry. 

TEMPERATURE INVERSIONS 

Applications should not occur during a temperaturelnvorsion because drift potential is high. Temperature inversions restrict vortlcal air 

mbdng, which causes small .uspended droplot1lto remain in a concontratGd OOud. Thi. cloud can move in unprGdidabfe d'troctlons due 

10 the light variable winds common during inversions. Temperature inversions are enaracterized by increasing tomperaturee with 

attitude and are rommon on nights with limited cloud cover and light to no wind. They begin to form ae tho sun sot. and often continuo 

into tho morning. Their prounco can be indicated by ground fog; however, if fog Is not presont, invera;ons can also be identified by tho 

movement 01 smoke from a ground source or an aircraft smoke gonerator. Smoke that layers and moves laterally in a concentrated 

cloud (under low wind condit;ons) indicates an inversIOn, while smoke that moves upward and rapidly dissipates indicate. good vertical 

air mIxing. 

SENSITIVE AREAS 

The pesticide should only be ~ied when the potential lor drift to adJacont sensitive areas (e.g. residential areas, bodies of water, 

known habitat for threatenod or endanger&d species, non·target crops) is minimal (e.g. whan wind is blowing away hom the sensflive J 

areas). !
