Precautionary Statements
Hazards to Humans and Domestic Animals
CAUTION. Harmful if swallowed.
Personal Protective Equipment (PPE)
Applicators and other handlers must wear:
• Long-sleeved shirt and long pants
• Chemical-resistant gloves made of waterproof material 
(barrier laminate, butyl rubber ≥ 14 mils, nitrile rubber 
≥ 14 mils, or Viton ≥ 14 mils)
• Shoes plus socks
Follow the manufacturer’s instructions for cleaning and 
maintaining PPE. If no such instructions for washables 
exist, use detergent and hot water. Keep and wash PPE 
separately from other laundry.
Engineering Controls Statement
When handlers use closed systems, enclosed cabs, or air-
craft 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/PPE 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
This product may contaminate water through drift of spray 
in wind.
This pesticide is toxic to fish and aquatic invertebrates. 
Drift and runoff may be hazardous to aquatic organisms in 
water adjacent to treated areas.
DO NOT apply directly to water, areas where surface 
water is present, or intertidal areas below the mean high 
water mark. DO NOT contaminate water when disposing 
of equipment washwaters or rinsate.
Groundwater Advisory
This chemical has properties and characteristics associat-
ed with chemicals detected in groundwater. Pyraclostrobin 
is known to leach through soil into groundwater under cer-
tain conditions as a result of label use. This chemical may 
leach into groundwater if used in areas where soils are 
permeable, particularly where the water table is shallow.
FIRST AID
If swallowed
• Call a poison control center or doctor immediately for treatment advice.
• Have person sip a glass of water if able to swallow.
• DO NOT induce vomiting unless told to do so by a poison control center or doctor.
• DO NOT give anything by mouth to an unconscious person.
If in eyes
• Hold eyes open and rinse slowly and gently with water for 15 to 20 minutes.
• Remove contact lenses, if present, after first 5 minutes; then continue rinsing eyes.
• Call a poison control center or doctor for treatment advice.
If on skin or clothing
• Take off contaminated clothing.
• Rinse skin immediately with plenty of water for 15 to 20 minutes.
• Call a poison control center or doctor for treatment advice.
If inhaled
• Move person to fresh air.
• If person is not breathing, call 911 or an ambulance; then give artificial respiration, preferably 
by mouth to mouth, if possible.
• Call a poison control center or doctor for further treatment advice.
Note to Physician: May pose an aspiration pneumonia hazard.
HOTLINE NUMBER
Have the product container or label with you when calling a poison control center or doctor or going for treatment. 
You may also contact BASF Agricultural Solutions US LLC (hereafter “BASF”) for emergency medical treatment infor-
mation: 1-800-832-HELP (4357).

Surface Water Advisory 
This product may impact surface water quality due to 
 runoff of rain water. This is especially true for poorly drain-
ing soils and soils with shallow ground water. This product 
is classified as having high potential for reaching surface 
water via runoff for several months or more after applica-
tion. A level, well-maintained vegetative buffer strip 
between areas to which this product is applied and 
 surface water features including ponds, streams, and 
springs will reduce the potential loading of pyraclostrobin 
from runoff water and sediment. Runoff of this product will 
be reduced by avoiding applications when rainfall or irriga-
tion is expected to occur within 48 hours. Sound erosion 
control practices will reduce this product’s contribution to 
surface water contamination.
Directions For Use
It is a violation of federal law to use this product in a man-
ner inconsistent with its labeling. DO NOT apply this 
 product in a way that will contact workers or other per-
sons, 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.

General Information
This package contains BAS 500 20 F fungicide, an 
aqueous capsule suspension. The active ingredient in 
BAS 500 20 F, pyraclostrobin, is a member of the 
 strobilurin class of chemistry and is derived from a 
natural antifungal substance. Preventive applications opti-
mize disease control, resulting in improved plant health.
To maximize disease control, apply BAS 500 20 F in a 
regularly scheduled protective spray program and use in a 
rotation program with other fungicides.
Because of its high specific activity, BAS 500 20 F has 
good residual activity against target fungi.
BAS 500 20 F is not for use in greenhouse or transplant 
production.
Mode of Action
Pyraclostrobin, the active ingredient of BAS 500 20 F, 
belongs to the group of respiration inhibitors classified by 
the U.S. EPA and Canada PMRA as Quinone Outside 
 Inhibitors (QoI), or target site of action Group 11 
fungicides.
Resistance Management
BAS 500 20 F contains pyraclostrobin, a Group 11 
 fungicide, and is effective against pathogens resistant to 
fungicides with modes of action different from those of 
QoI fungicides (target site Group 11), such as 
 dicarboximides, sterol inhibitors, benzimidazoles, or 
phenylamides.
Fungal isolates resistant to Group 11 fungicides, such as 
pyraclostrobin, azoxystrobin, fluoxastrobin, trifloxystrobin, 
and kresoxim-methyl, may eventually dominate the fungal 
population if Group 11 fungicides are used predominantly 
and repeatedly in the same field in successive years as the 
primary method of control for the targeted pathogen spe-
cies. This may result in reduction of disease control by 
BAS 500 20 F or other Group 11 fungicides. Follow label 
instructions regarding the use of BAS 500 20 F or other 
target site of action Group 11 fungicides that have a simi-
lar site of action on the same pathogens.
When using a Group 11 fungicide as a solo product, the 
number of applications must be no more than 1/3 of the 
total number of fungicide applications per season.
In programs in which tank mixes or pre-mixes of a 
Group 11 fungicide with a fungicide of another group are 
utilized, the number of Group 11 fungicide (QoI)- containing 
applications should be no more than 1/2 of the total num-
ber of fungicide applications per season.
In programs in which applications of Group 11 fungicides 
are made with both solo products and mixtures, the num-
ber of Group 11 fungicide (Qol)-containing applications 
should be no more than 1/2 of the total number of fungi-
cide applications per season.
For resistance management, BAS 500 20 F contains a 
Group 11 fungicide. Any fungal population may contain 
individuals naturally resistant to BAS 500 20 F and other 
Group 11 fungicides. A gradual or total loss of pest con-
trol may occur over time if these fungicides are used 
repeatedly in the same fields. Appropriate resistance- 
management strategies should be followed.

5
To delay fungicide resistance, take one or more of the fol-
lowing steps: 
• Rotate the use of BAS 500 20 F fungicide or other 
Group 11 fungicides within a growing season sequence 
with different groups that control the same pathogens.
• Use tank mixtures with fungicides from different target-
site-of-action groups that are registered/permitted for the 
same use and that are effective against the pathogens of 
concern. Use at least the minimum application rate as 
labeled by the manufacturer.
• Adopt an integrated disease management program for 
fungicide use that includes scouting, uses historical infor-
mation related to pesticide use, and crop rotation, and 
which considers host plant resistance, impact of environ-
mental conditions on disease development, disease 
thresholds, as well as cultural, biological and other chemi-
cal control practices to reduce disease development. 
• Consult your local extension specialist, certified crop 
advisor and/or BASF representative for additional IPM 
strategies established for your area. BAS 500 20 F can 
be used in agricultural extension advisory (disease fore-
casting) programs, which recommend application timing 
based on environmental factors favorable for disease 
development.
• Where possible, make use of predictive disease models 
to effectively time fungicide applications. Note that using 
predictive models alone is not sufficient to manage 
resistance.
• Monitor treated fungal populations for resistance 
development.
• Monitor efficacy of all fungicides used in the disease 
management program against the targeted pathogen 
and record other factors that may influence fungicide 
performance and/or disease development. If a Group 11 
target-site fungicide, such as BAS 500 20 F, appears to 
be less effective against a pathogen that it previously 
controlled or suppressed, contact a BASF representa-
tive, local extension specialist, or certified crop advisor 
for further investigation.
• Contact your local extension specialist or certified crop 
advisor for any additional pesticide resistance- management 
and/or IPM recommendations for specific crops and 
pathogens.
Application Instructions
Apply rate of BAS 500 20 F as instructed in BAS 500 20 F 
fungicide Crop-specific Requirements . Apply 
BAS 500 20 F with ground sprayer, aerial equipment or 
through sprinkler irrigation equipment. Check equipment 
frequently for calibration.
Under low-level disease conditions, the minimum applica-
tion rates can be used while maximum application rates 
and shortened spray schedules are recommended for 
severe or threatening disease conditions.
The use of a crop oil or adjuvant may be used to improve 
spray coverage. Refer to the adjuvant product label for 
specific use directions and restrictions. For optimum 
results in cases of high disease pressure, use a minimum 
spray volume of 4 gpa.
Consult a BASF representative or local agricultural authori-
ty for more information concerning additives.
Cleaning Spray Equipment
Spraying equipment must be cleaned thoroughly before 
and after applying this product, particularly if a product 
with the potential to injure crops was used prior to 
BAS 500 20 F.
Ground Application
Apply BAS 500 20 F in sufficient water to ensure thorough 
coverage of foliage. Thorough coverage is required for 
optimum disease control.
Instructions for Directed or Banded Sprays 
Related to Ground Applications
The application rate shown in BAS 500 20 F fungicide 
Crop-specific Requirements pertains to both aerial and 
ground (broadcast) methods of application. BAS 500 20 F 
may also be applied as a directed or banded spray over 
the rows or plant beds with alleys or row middles left 
unsprayed. For such uses, reduce the rate of 
BAS 500 20 F in proportion to the area actually sprayed. 
This adjustment is necessary to prevent applying the prod-
uct at use rates higher than permitted on this label.
The following formula may be used to determine the 
broadcast equivalent rate for doing directed or banded 
sprays:
sprayed bed width + unsprayed row middles = 
total row width
sprayed bed 
width in inches x broadcast rate = band rate
total row 
width in inches
treated acre field acre
Example: A directed spray application will be made to 
45-inch plant beds separated by 15 inches of unsprayed 
row-middles.
45 inches sprayed bed width + 15 inches unsprayed row 
middles = 60 inches total row width
The calculations to determine the appropriate equivalent 
rate of product to use for this situation based on a label 
broadcast rate of 6 fl ozs/acre follows:
45 inches 
sprayed bed width x
6 fl ozs 
BAS 500 20 F=
4.5 fl ozs 
BAS 500 20 F

Aerial Application
Unless otherwise specified on this label, use no less than 
2 gallons of spray solution per acre.
Aerial applications of BAS 500 20 F fungicide may be 
made in water volumes of 2 or more gallons of spray solu-
tion per acre (gpa).
Select spray nozzles, pumping pressure, and sprayer 
height to provide spray droplets that penetrate throughout 
the crop canopy. Spray calibration must be conducted to 
confirm spray droplet sizes. Continue to monitor spray 
application (including weather conditions) to assure proper 
droplet size and canopy penetration.
No aerial application in New York State except as 
permitted under FIFRA Section 24(c), Special Local 
Need Registration.
Aerial Application Methods and Equipment
The interaction of many equipment-related and weather- 
related factors determines the potential for spray drift. The 
applicator and the grower are responsible for considering 
all these factors when making decisions.
DO NOT apply under circumstances where possible drift 
to unprotected persons, to food, forage, or other plantings 
that might be damaged, or crops thereof rendered unfit for 
sale, use or consumption can occur.
The following drift management requirements must be fol-
lowed to avoid off-target drift movement to agricultural field 
crops. These requirements do not apply to forestry appli-
cations, public health uses or to applications using dry 
formulations.
Mandatory Spray Drift Management
Aerial Applications:
• DO NOT release spray at a height greater than 10 ft 
above the ground or vegetative canopy, unless a great-
er application height is necessary for pilot safety.
• Applicators are required to select nozzle and pressure 
that deliver a medium or coarser droplet size 
(ASABE S641).
• DO NOT apply when wind speeds exceed 15 mph at 
the application site. If the windspeed is greater than 
10 mph, the boom length must be 65% or less of the 
wingspan for fixed wing aircraft and 75% or less of the 
rotor diameter for helicopters. Otherwise, the boom 
length must be 75% or less of the wingspan for fixed-
wing aircraft and 90% or less of the rotor diameter for 
helicopters
• If the windspeed is 10 miles per hour or less, applica-
tors must use 1/2 swath displacement upwind at the 
downwind edge of the field. When the windspeed is 
between 11 to 15 miles per hour, applicators must use 
3/4 swath displacement upwind at the downwind edge 
of the field.
• DO NOT apply during temperature inversions.
(continued)
Mandatory Spray Drift Management 
(continued)
Ground Boom Applications:
• User must only apply with the release height recom-
mended by the manufacturer, but no more than 4 ft 
above the ground or crop canopy.
• Applicators are required to select nozzle and pressure 
that deliver a medium or coarser droplet size 
(ASABE S572). 
• DO NOT apply when wind speeds exceed 15 miles 
per hour at the application site.
• DO NOT apply during temperature inversions.
Spray Drift Advisories
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING 
 OFF-SITE SPRAY DRIFT. BE AWARE OF NEARBY 
NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS. 
Importance of Droplet Size
An effective way to reduce spray drift is to apply large drop-
lets. Use the largest droplets that provide target pest 
control. While applying larger droplets will reduce spray drift, 
the potential for drift will be greater if applications are made 
improperly or under unfavorable environmental conditions.
Controlling Droplet Size – Ground Boom 
• Volume - Increasing the spray volume so that larger 
droplets are produced will reduce spray drift. Use the 
highest practical spray volume for the application. If a 
greater spray volume is needed, consider using a nozzle 
with a higher flow rate.
• Pressure - Use the lowest spray pressure recommend-
ed for the nozzle to produce the target spray volume and 
droplet size. 
• Spray Nozzle - Use a spray nozzle that is designed for 
the intended application. Consider using nozzles 
designed to reduce drift. 
Controlling Droplet Size - Aircraft 
• Adjust Nozzles - Follow nozzle manufacturers’ recom-
mendations for setting up nozzles. Generally, to reduce 
fine droplets, nozzles should be oriented parallel with the 
airflow in flight.
Boom Height - Ground Boom
For ground equipment, the boom should remain level with 
the crop and have minimal bounce.
Release Height - Aircraft 
Higher release heights increase the potential for spray drift.
Shielded Sprayers
Shielding the boom or individual nozzles can reduce spray 
drift. Consider using shielded sprayers. Verify that the 
shields are not interfering with the uniform deposition of 
the spray on the target area.
Temperature and Humidity
When making applications in hot and dry conditions, use 
larger droplets to reduce effects of evaporation.

7
Temperature Inversions
Drift potential is high during a temperature inversion. 
 Temperature inversions are characterized by increasing 
temperature with altitude and are common on nights with 
limited cloud cover and light to no wind. The presence of 
an inversion can be indicated by ground fog or 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 mixing. Avoid applica-
tions during temperature inversions.
Wind
Drift potential generally increases with wind speed. AVOID 
APPLICATIONS DURING GUSTY WIND CONDITIONS. 
Applicators need to be familiar with local wind patterns 
and terrain that could affect spray drift.
Boomless Ground Applications 
Setting nozzles at the lowest effective height will help to 
reduce the potential for spray drift.
Handheld Technology Applications
Take precautions to minimize spray drift.
Directions For Use Through Sprinkler 
Irrigation Systems
Sprayer Preparation
Chemical tank and injector system should be thoroughly 
cleaned. Flush system with clean water.
Application Instructions
Apply BAS 500 20 F fungicide at rates and timings as 
required in this label.
Use Precautions For Sprinkler Irrigation 
Applications
• Apply this product only through sprinkler irrigation sys-
tems including center pivot, lateral move, end tow, side 
[wheel] roll, traveler, big gun, solid set, or hand move irri-
gation systems. DO NOT apply this product through any 
other type of irrigation system.
• Add this product to the pesticide supply tank containing 
sufficient water to maintain a continuous flow by the 
injection equipment. In continuous moving systems, 
inject this product/water mixture continuously, applying 
the labeled rate per acre for that crop. DO NOT exceed 
1/2 inch (13,577 gallons) per acre. In stationary or non-
continuous moving systems, inject the product/water 
mixture in the last 15 to 30 minutes of each set allowing 
sufficient time for all of the required pesticide to be 
applied by all the sprinkler heads and applying the 
labeled rate per acre for that crop. DO NOT apply when 
wind speed favors drift beyond the area intended for 
treatment. Crop injury, lack of effectiveness, or illegal 
pesticide residues in the crop can result from non- 
uniform distribution of treated water. Thorough coverage 
of foliage is required for good control. Maintain good agi-
tation during the entire application period.
• Contact state extension service specialists, equipment 
manufacturers or other experts for further investigation.
• 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 func-
tional, 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 with-
drawn 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 function-
al pressure switch that 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), 
effectively designed and constructed of materials that are 
compatible with pesticides and capable of being fitted 
with a system interlock.
• Allow sufficient time for pesticide to be flushed through 
all lines and all nozzles before turning off irrigation water. 
A person knowledgeable of the chemigation system and 
responsible for its operation, or under supervision of the 
responsible person, shall shut the system down and 
make necessary adjustments should the need arise.
• DO NOT connect an irrigation system (including green-
house systems) used for pesticide application to a public 
water system unless the pesticide label-prescribed safe-
ty devices for public water systems are in place.
Specific Instructions for Public Water 
Systems:
1. 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.
2. Chemigation systems connected to public water sys-
tems must contain a functional, reduced-pressure zone, 
backflow preventer (RPZ) or the functional equivalent in 
the water supply line upstream from the point of pesti-
cide introduction. As an option to the RPZ, the water 
from the public water system should be discharged into 
a reservoir tank prior to pesticide introduction. There 
shall be a complete physical break (air gap) between the

8
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.
3. The pesticide injection pipeline must contain a function-
al, automatic, quick-closing check valve to prevent the 
flow of fluid back toward the injection pump.
4. The pesticide injection pipeline must contain a function-
al, 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 with-
drawn from the supply tank when the irrigation system is 
either automatically or manually shut down.
5. 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.
6. Systems must use a metering pump, such as a positive 
displacement injection pump (e.g. diaphragm pump), 
effectively designed and constructed of materials that 
are compatible with pesticides and capable of being fit-
ted with a system interlock.
Additives and Tank Mixing Information
BAS 500 20 F fungicide can be tank mixed with most 
recommended fungicides, insecticides, herbicides, liquid 
fertilizers, biological control products, adjuvants, and 
 additives as specified in BAS 500 20 F fungicide 
Crop-specific Requirements .
Under some conditions, the use of additives or adjuvants 
may improve the performance of BAS 500 20 F. However, 
all varieties and cultivars have not been tested with possi-
ble tank mix combinations. Local conditions can also 
influence crop tolerance and may not match those under 
which BASF has conducted testing. Physical incompatibili-
ty, reduced disease control, or crop injury may result from 
mixing BAS 500 20 F with other products. Therefore, 
before using any tank mix (fungicides, insecticides, herbi-
cides, liquid fertilizers, biological control products, 
adjuvants and additives), test the combination on a small 
portion of the crop to be treated to ensure that a phytotox-
ic response will not occur as a result of application. Always 
follow the most restrictive label.
When an adjuvant is to be used with this product, BASF 
recommends the use of a Council of Producers & 
 Distributors of Agrotechnology certified adjuvant.
Consult a BASF representative or local agricultural authori-
ties for more information concerning additives.
Mixing Order
1. Water - Begin by agitating a thoroughly clean sprayer 
tank 3/4 full of clean water.
2. Agitation - Maintain constant agitation throughout mix-
ing and application.
3. Inductor - If an inductor is used, rinse it thoroughly 
after each component has been added.
4. Products in PVA bags - Place any product contained 
in water-soluble PVA bags into the mixing tank. Wait 
until all water-soluble PVA bags have fully dissolved and 
the product is evenly mixed in the spray tank before 
continuing.
5. Water-dispersible products (such as dry flowables, 
wettable powders, suspension concentrates, including 
BAS 500 20 F or suspo-emulsions)
6. Water-soluble products
7. Emulsifiable concentrates (such as oil concentrates 
when applicable)
8. Water-soluble additives (such as ammonium sulfate 
[AMS] or urea ammonium nitrate [UAN] when applicable)
9. Remaining quantity of water
Make sure that each component is thoroughly mixed and 
suspended before adding tank mix partners. Maintain con-
stant agitation during application.
Restrictions and Limitations
• DO NOT apply more than 6 fl ozs BAS 500 20 F per 
acre per season.
