Theapplicatar shauld be familiar with and take into accauntthe infarmatian covered in the Aerial Drift Reductian Advisary below: 

## AERIALDRIFTREDUCTIONADVISORY [This sectian is advisary in nature and daes not supersede the mandatory label requirements). INFORMATION ON DROPLETSIZE The mast effective way to reduce drift patential is to. apply large draPlets. The best drift management strategy is to. apply the largest draplets that provide sufficient coverage and co.ntrol. Applying larger droplets reduces drift patential, but will nat prevent drift if applicatians are made improperly, or under unfavarable environmental canditians (See Wind, Temperature and Humidity, and Temperature Inversians). CONTROLLING DROpLETSJZE Volume

- Use high flow rate nazzles to. apply the highest practical spray volume. Nazzles with higher rated flaws praduce larger droplets. Pressure

- Do nat exceed the nozzle manufacturer's recammended pressures. Far many nazzle types lawer pressure rr')r1uces larger draplets. When higherflaw rates are needed, use higherflaw rate nazzles instead af increasing pressure. Numberaf nazzles

- Use the minimum numberaf nazzlesthat provide unifarm caverage. Nazzle Orientatian

- Orienting nazzles so that the spray is released parallel to the airstream produces larger droplets than ather arientatians and is the recammended practice. Significant deflectian fram harizantal will reduce draplet

BOOM LENGTH Far same use patterns, reducing the effective baam length to. less than 3f4 af the wingspan ar ratar length may ft::iher**~educe** drift withaut reducing swath width. APPLICATION HEIGHT Applicatians shauld nat be made at a height greater than 10 feet abave the tap of the target plants unless a greater height is required for aircraft safety. Making applicatians at the lawest height that issafe reduces expasure afdroplets to. evaporatian andwind. 2

## (

SWATH ADJUSTMENT When applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the up and downwind edges of the field, the applicator should compensate for this displacement by adjusting the path of the aircraft upwind. Swath adjustment distance should increase, with increasing drill potential (higherwind, smaller drops, etc.). WIND Drift potential is lowest between wind speeds of 2 • 10 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 influence wind pattems. Every applicator should be tamiliar with local wind patlems 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 dropletsto remain in a concentrated cloud. This doud 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 lightto no wind. They begin to form as the sun sets and often continue into the moming. 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 lowwind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. SENStTtVE AREAS The 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, non-target crops) is minimal (e.g. when wind is blowing away from the sensitive areas). 

## GENERALINFORMATION CERONE® brand Ethephon Plant Regulator is intended for use as a lOdging reduction agent in barley and wheat crops and in grasses grown for seed production. Use CERONE@only on vigorously growing crops that are likely to lodge. Do not use CERONE® In nonlodging situations orwhere lodging causes only minimal yield loss. lodged crops increase harvest costs and decrease harvest efficiency and recoverable yields. lodging can cause uneven maturity, higher moisture content and loss of grain quality. In grasses grown for seed lodging at anthesis 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 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 loss. 

# DIRECTIONSFORUSE It is a violation of Federal Lawto use this product in a manner inconsistentwith its labelIng. Do notapplythisproduct in a waythatwIll contactworkers or other persons, eitherdirectlyorthrough drift. Only protected

### 4Do not plant another crop within 30 days after treatment. 

## TREATMENTDECISION GUIDE Important- Inspect fields just prior to application to determine the probability of lodging. Use CERONE® brand Ethephon Plant Regulator only under the following conditions: 1. The crop is expected to lodge and significant loss 01 recoverable yield, grain quality, and/or harvest efliciency is expected. 2. The crop is free of stress lrom disease or insect damage. 3. Soil moisture or irrigation is adequate to preventcrop stress after application. 4. Temperature fluctuations (below 35° F or above 85° F non-irrigated and 900 F irrigated) are not expected lor 5 days after application. 5. Application can be made at the correct stage. Feekes 8 to 10

- see growth stage chart. 

## SPRAY PREPARATION Add 

### 1/2 to 3/4 of the required amount of water to the spray tank and begin agitation. Add the required amount of CERONE® brand Ethephon Plant Regulator followed bythe remaining amount of water. Prepare only as much spray solution as can be used on the day ofmixing. Use of previous day's spray mix may result in reduced activity. Do not spill the concentrated product on spray eqUipment, or any airplane parts. Any spilfs should be rinsed Immediately with plenty ofwater as CERONE® brand Ethephon Plant Regulator is corrosive. Use of a nurse tank is recommended to avoid possible spills of concentrated formulation on spray equipment orairplane parts. 

## EQUIPMENT CLEANING Because 01 the acidic nature of this product, prolonged exposure to spray deposits will damage acrylic plastics, certain paints, and metals. Rinse thoroughly with a detergent and water all exposed acrylic plastic-type materials (e.g., aircraft windshields), and painted surfaces within an hour after exposure to spray deposits. 

### At the end of each day, rinse thoroughly with a detergent and water 

### the spray system and all the metal parts 01 the aircraft exposed 

### to the spray depOSits.


## WHEATAND BARLEY COMPATIBILITY CERONe1D brand Ethephon Plant Regulator can be tank-mixed with approved cereal insecticides and fungicides. Treatment is intended as a preventive measure. Insecticide and fungicide treatment programs should be based on timely scouting and economic threshold assessments. This may not coincide with CERONE® application timing. Do not use CERONE® as a tank mixture with insecticides or fungicides on crops stressed 

### by adverse weather conditions, referenced above, or by insect or disease damage. Crop Injury or yield loss may result with tank mix application under stress conditions. (i.e. moisture, heat, cold, insect, dIsease). CERONE® 

### + TIn® tank mix application by air made under stress conditfons may result in flag leaf bum and yIeld loss.

. Do not tank mix with herbicides or nitrogen solutions. Do not add adjuvants, surfactants or wefting agents to CERONE®brarid Ethephon Plant Regulator. APPLICATION TIMING Apply when the flag leaf is just visible to boot stage, but before the awns have emerged or the sheath has split (Feekes-Large Scale 8-10, Zadok's Code 37-45). Do not allow spray solution to contact exposed heads, as damage and reduced yield may result. Inspect fields carefully to determine that application can be made at the proper stage. APPLICATION ForCERONE® brand Ethephon Plant Regulator to be effective temperature after application should be at least GO°F. Avoid spray overlap which can result in excess rate and yield loss. GROUND: Use a minimum of 7 gallons of water per acre when applied by conventional ground**eq'liprren~.** Flat Ian nozzles are recommended. Use a minimum of 5 gallons of water per acre with controlled droplet application {COA} or air foil**typ~ !!q·J·F~ent.**  To prevent uneven application adjust spray boom to plantcanopy height and operate at moderate speed. AIR: Use a minimum of3 gallons of water per acre. USE RATES Lodging pressure and environmental conditions will affect the CERONE® brand Ethephon Plant Regulator rate needed. On more responsive varieties use only the 0.5 pint per acre rate. Consult your state extension specialist or Bayer CropScience representative for more inlormation. Do not apply more than a total of 1.0 pint (0.5 lb. active) of**CERON~** brand Ethephon Plant Regulator per acre peryear. Do not harvest wheat or barley within 40 days of last CERONE® brand Ethephon Plant Regulator application.
