Dear Shannon Whitlock: 
 
The amended label referred to above, submitted in connection with registration under the Federal 
Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended, is acceptable. This approval 
does not affect any conditions that were previously imposed on this registration. You continue to 
be subject to existing conditions on your registration and any deadlines connected with them. 
 
A stamped copy of your labeling is enclosed for your records. This labeling supersedes all 
previously accepted labeling. You must submit one copy of the final printed labeling before you 
release the product for shipment with the new labeling. In accordance with 40 CFR 152.130(c), 
you may distribute or sell this product under the previously approved labeling for 18 months 
from the date of this letter. After 18 months, you may only distribute or sell this product if it 
bears this new revised labeling or subsequently approved labeling. “To distribute or sell” is 
defined under FIFRA section 2(gg) and its implementing regulation at 40 CFR 152.3. 
 
Should you wish to add/retain a reference to the company’s website on your label, then please be 
aware that the website becomes labeling under FIFRA and is subject to review by the Agency. If 
the website is false or misleading, the product would be misbranded and unlawful to sell or 
distribute under FIFRA section 12(a)(1)(E). 40 CFR 156.10(a)(5) lists examples of statements 
EPA may consider false or misleading. In addition, regardless of whether a website is referenced 
on your product’s label, claims made on the website may not substantially differ from those 
claims approved through the registration process. Therefore, should the Agency find or if it is 
brought to our attention that a website contains false or misleading statements or claims 
substantially differing from the EPA approved registration, the website will be referred to the 
EPA’s Office of Enforcement and Compliance.

Environmental Hazards 
 
This product is toxic to fish and aquatic invertebrates, including shrimp and oysters. Drift and runoff may 
be hazardous to aquatic organisms in water adjacent to treated areas. DO NOT apply directly to water, or

T1C / Aproach Prima / MSTR / Amend / 12-13-22 Page 7 
 
 
to areas where surface water is present, or to intertidal areas below the mean high water mark. DO NOT 
contaminate water when disposing of equipment washwater or rinsate. 
 
Surface Water Advisory: Picoxystrobin has the potential to contaminate surface water through spray 
drift. Under some conditions, picoxystrobin may also have a high potential for runoff into surface water, 
especially in areas with poorly-draining soils, and areas with shallow water tables. A level, well-
maintained vegetative buffer strip between areas to which this product is applied and surface water will 
reduce the potential for runoff. Runoff of this product will be reduced by avoiding applications when 
rainfall is forecasted to occur within 48 hours. 
 
Ground Water Advisory: Cyproconazole demonstrates the properties and characteristics associated 
with chemicals detected in groundwater. The use of this product in areas where soils are permeable, 
particularly where the water table is shallow, may result in groundwater contamination.

Product Information 
 
Aproach Prima Fungicide is a broad-spectrum fungicide for control of foliar plant diseases and has 
preventive, curative, and systemic activity. Aproach Prima Fungicide must be applied in a regularly 
scheduled protective spray program in rotation with other fungicides. When used in a disease control 
program, Aproach Prima Fungicide improves plant health, vigor, and yield. See directions below for 
specific crop/disease instructions. 
 
Aproach Prima Fungicide rapidly penetrates plant tissues and is rainfast within 1-hour after application. 
 
This product may be applied to crop sites that contain areas of temporary surface water caused by 
collection of water between planting beds, in equipment ruts, or in other depressions caused by 
management activities. 
 
Integrated Pest Management 
This product may be used as part of an Integrated Pest Management (IPM) program that can 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 disease forecasting models reach locally determined action thresholds. 
Consult your state cooperative extension service, professional consultants, or other qualified authorities 
to determine appropriate action treatment threshold levels for treating specific pest/crop or site systems in 
your area. 
 
Resistance Management 
For resistance management, Aproach Prima Fungicide contains both a Group 3 and a Group 11 
fungicide. Any fungal population may contain individuals naturally resistant to Aproach Prima Fungicide 
and other Group 3 or Group 11 fungicides. A gradual or total loss of pest control may occur over time if 
these fungicides are used repeatedly in the same fields. Appropriate resistance-management strategies 
must be followed. 
 
To delay fungicide resistance, take one or more of the following steps: 
• Rotate the use of Aproach Prima Fungicide or other Group 3 and Group 11 fungicides within a growing 
season sequence with different groups that control the same pathogens. Avoid application of more than 
two consecutive sprays of Aproach Prima Fungicide or other fungicides in the same group in a season. 
• Use tank mixtures with fungicides from a different group that are equally effective on the target pest 
when such use is permitted. 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 information related to pesticide use, and crop rotation, and which considers host plant 
resistance, impact of environmental conditions on disease development, disease thresholds, as well as 
cultural, biological and other chemical control practices. 
• 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. 
• Contact your local extension specialist or certified crop advisor for any additional pesticide resistance-
management and/or IPM for specific crops and pathogens. 
• For information or to report suspected resistance contact your company representative. You can also 
contact your pesticide distributor or university extension specialist to report resistance. 
 
Application Information 
 
Application Equipment 
Aproach Prima Fungicide may be applied with ground, air or chemigation equipment. 
 
Application Volume

T1C / Aproach Prima / MSTR / Amend / 12-13-22 Page 10 
 
 
Use a sufficient volume of water to ensure thorough coverage when applying Aproach Prima Fungicide as

DO NOT use an adjuvant or crop oil when applying Aproach Prima Fungicide on corn between the V8 
and VT stages of growth. 
 
It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read 
and follow the applicable restrictions and limitations and directions for use on all product labels involved in 
tank mixing. Users must follow the most restrictive directions for use and precautionary statements of 
each product in the tank mixture. 
 
The crop safety of all tank mixtures with Aproach Prima Fungicide which may include physically 
compatible pesticides, fertilizers, adjuvants, and/or additives, has not been tested. When considering the 
use of a tank mixture on a labeled crop without prior experience, or which is not specifically described on 
Aproach Prima Fungicide product labeling or in other Corteva Agriscience product use instruction, it is 
important to understand crop safety. To test for crop safety, prepare a small volume of the intended tank 
mixture, apply it to an area of the target crop as directed by both this and the tank mix partner product 
labels, and observe the treated crop to ensure that a phytotoxic response does not occur. Corteva 
Agriscience will not be responsible for any crop injury arising from the use of a tank mixture that is not 
specifically described on Aproach Prima Fungicide product labeling or in other Corteva Agriscience 
product use instruction. Always follow the tank mix instructions of the product label that is most restrictive. 
 
Research indicates that some materials including oils, surfactants, adjuvants and pesticide formulations 
when applied individually, sequentially, or in tank mixtures may solubilize the plant cuticle, facilitate 
penetration into plant tissue, and increase the potential for crop injury. 
 
Consult a company representative or local agricultural authorities for more information concerning tank 
mixtures. 
 
Physical Compatibility 
Aproach Prima Fungicide is physically compatible with many commonly used fungicides, herbicides, 
insecticides, biological control products, liquid fertilizers, non-ionic surfactants, crop oils, methylated seed 
oils and drift control additives. However, since the formulations of products change, it is important to test 
the physical compatibility of desired tank mixes and check for undesirable physical effects, including 
settling out or flocculation. To determine physical compatibility, add the proportions of the tank mix 
products and water to a small container, mix thoroughly and allow to stand for 20 minutes. If the 
combination remains mixed, or can be re-mixed readily, it may be considered physically compatible.

10. drift control additives 
 
Chemigation 
Apply Aproach Prima Fungicide only through sprinkler irrigation systems (including center pivot, lateral 
move, end tow, side (wheel) roll, traveler, big gun, solid set or hand move irrigation systems). 
 
Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from non-uniform 
distribution of treated water. If you have questions about calibration, contact your State Extension Service 
Specialists, equipment manufacturers or other experts. 
 
DO NOT connect an irrigation system (including greenhouse systems) used for pesticide application to a 
public water system unless the pesticide label-prescribed safety devices for public water systems are in 
place. 
 
A person knowledgeable of the chemigation system and responsible for its operation, or under the 
supervision of the responsible person, must shut the system down and make necessary adjustments if 
the need arise. 
 
Specific Instructions for Public Water Systems: 
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. 
 
Chemigation systems connected to public water systems must contain a functional, reduced-pressure 
zone, backflow preventer (RPZ) or the functional equivalent in the water supply line upstream from the 
point of pesticide introduction. As an option to the RPZ, the water from the public water system must be 
discharged into a reservoir tank prior to pesticide introduction. There shall be a complete physical break 
(air gap) between the 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. 
 
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 contain a functional, 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 withdrawn 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, or in cases where there is no water pump, when the water 
pressure decreases to the point where pesticide distribution is adversely affected. 
 
Systems must use a metering pump, including 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. 
 
Specific Instructions for Sprinkler Irrigation Systems: 
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 functional, 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 withdrawn from the supply tank when the irrigation system is either automatically or manually

T1C / Aproach Prima / MSTR / Amend / 12-13-22 Page 12 
 
 
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 functional pressure switch which 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, including 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. 
 
DO NOT apply when wind speed favors drift beyond the area to be treated. 
 
Good agitation is required in the injection tank. In moving systems, apply specified dosage of Aproach 
Prima Fungicide as a continuous injection. In nonmoving systems inject Aproach Prima Fungicide for 15 
to 30 minutes at end of cycle. Use the least amount of water possible consistent with uniform coverage. 
 
Mix a label specified amount of Aproach Prima Fungicide needed for acreage to be treated into the 
quantity of water determined during prior calibration. For moving systems inject into the system 
continuously for one complete revolution of the field. For nonmoving systems inject into system for the 
time established during calibration. 
 
Stop injection equipment after completing treatment; continue to operate irrigation equipment until all 
Aproach Prima Fungicide is flushed from the system.

T1C / Aproach Prima / MSTR / Amend / 12-13-22 Page 13 
 
 
Important Precautions 
Not all crops within a crop group, and not all varieties, cultivars or hybrids of crops, have been individually 
tested for crop safety. It is not possible to evaluate for crop safety all applications of Aproach Prima on all 
crops within a crop group, on all varieties, cultivars, or hybrids of those crops, or under all environmental 
conditions and growing circumstances. To test for crop safety, apply the product in accordance with the 
label instructions to a small area of the target crop to ensure that a phytotoxic response will not occur, 
especially where the application is a new use of the product by the applicator. 
 
Equipment Cleaning 
Prior to application, start with clean, well maintained application equipment. Immediately following 
application, thoroughly clean all spray equipment to reduce the risk of forming hardened deposits which 
might become difficult to remove. 
 
Drain spray equipment. Thoroughly rinse sprayer and flush hoses, boom and nozzles with clean water. 
Clean all other associated application equipment. Take all necessary safety precautions when cleaning 
equipment. DO NOT clean near wells, water sources or desirable vegetation. 
 
Dispose of waste rinse water in accordance with local regulations.

SPRAY DRIFT ADVISORIES 
THE APPLICATOR IS RESPONSIBLE FOR AVAOIDING 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 droplets. 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 Application 
• 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 directed 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’ specifications for setting up nozzles. To reduce fine 
droplets, nozzles must be oriented parallel with the airflow in flight. 
 
BOOM HEIGHT – Ground Boom 
For ground equipment, keep the boom 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.

T1C / Aproach Prima / MSTR / Amend / 12-13-22 Page 18 
 
 
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 air mixing. Avoid applications during temperature inversions. 
 
WIND 
Drift potential 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. 
 
Air Assisted (Air Blast) Field Crop Sprayers 
Air assisted field crop sprayers carry droplets to the target via a downward directed air stream. Some may 
reduce the potential for drift, but if a sprayer is unsuitable for the application and/or set up improperly, 
high drift potential can result. It is the responsibility of the applicator to determine that a sprayer is suitable 
for the intended application, that it is configured properly, and that drift potential has been minimized. 
Note: Air assisted field sprayers can affect product performance by affecting spray coverage and canopy 
penetration. Read the specific crop use and application equipment instructions to determine if an air 
assisted field crop sprayer can be used. 
 
Sensitive Areas 
Making applications when there is a sustained wind moving away from adjacent sensitive areas (e.g., 
residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops) 
is an effective way to minimize the effect of spray drift. 
 
Drift Control Additives 
Using product compatible drift control additives can reduce drift potential. When a drift control additive is 
used, read and carefully observe cautionary statements and all other information on the additive’s label. If 
using an additive that increases viscosity, ensure that the nozzles and other application equipment will 
function properly with a viscous spray solution. Preferred drift control additives have been certified by the 
Chemical Producers and Distributors Association (CPDA).
