Environmental Hazards 
 
This pesticide is toxic to fish, aquatic invertebrates, and oysters. For terrestrial uses: Do not apply directly 
to water, or 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. Drift and runoff may 
be hazardous to aquatic organisms in water adjacent to treated areas. 
 
Surface Water Advisory: This product may impact surface water quality due to runoff of rain water. This 
is especially true for poorly draining soils and soils with shallow ground water. This product is classified as 
having high potential for reaching surface water via runoff several weeks after application. A level, well-
maintained vegetative buffer strip between areas to which this product is applied and surface water 
features such as ponds, streams, and springs will reduce the potential loading of this chemical from runoff 
water and sediment. Runoff of this product will be reduced by avoiding applications when rainfall is 
forecasted to occur within 48 hours.

Product Information 
 
Vertisan® fungicide (referred to below as Vertisan fungicide or Vertisan), an emulsifiable concentrate 
containing penthiopyrad, is recommended for use as a spray for the control of many important listed plant 
diseases. 
 
Vertisan must be used only in accordance with instructions on this label, in separately issued labeling or 
exemptions under FIFRA (Supplemental Labels, Special Local Need Registration, FIFRA Section 18 
exemptions), or as otherwise permitted by FIFRA. Always read the entire label including the Limitation of 
Warranty and Liability. 
 
Vertisan is a broad-spectrum fungicide, recommended for control of foliar and soil-borne plant diseases 
and has preventive, curative, and locally systemic activity. Vertisan must be applied in a regularly 
scheduled protective spray program in rotation with other fungicides. See directions below for specific 
crop/disease recommendations. 
 
Vertisan can be applied with commonly used ground equipment, hose-end, or pressurized sprayers, and 
air or chemigation equipment, except as otherwise directed, using sufficient water to obtain thorough 
coverage of plants. Thorough coverage of all foliage is essential for effective disease control. Maintain 
agitation during mixing and application to assure uniform product suspension. 
 
 
Use Restrictions 
 
- Use this product only in commercial and farm plantings. 
- Do not use for home plantings. 
- Do not formulate this product into other end-use products. 
- In New York, do not sell, sell into, distribute, or use in Nassau or Suffolk Counties. 
- In New York, do not exceed 61 fl oz (0.80 lb ai) per acre per year. 
 
Application Volumes 
 
x For conventional ground application, apply a minimum of 15 gallons per acre, increasing the 
spray volume as the plants mature to ensure thorough coverage of foliage. 
x For air-assisted ground application, apply a minimum of 10 gallons per acre. 
x For aerial application, apply a minimum of 2 gallons per acre. 
 
Rainfastness: Vertisan rapidly penetrates into plant tissues and is rainfast within 1 hour after application. 
 
CULTIVAR/VARIETAL CROP SAFETY 
 
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 Vertisan 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. 
 
INTEGRATED PEST MANAGEMENT 
 
Corteva recommends the use of Integrated Pest Management (IPM) programs to control pests. Vertisan 
may be used as part of an IPM program which can include biological, cultural, and genetic practices

Vertisan / MSTR / Amend / 04-22-24 Page 6 
 
aimed at preventing economic pest damage. Application of this product should be based on IPM 
principles and practices including field scouting or other detection methods, correct target pest 
identification, population monitoring, and treating when disease forecasting models reach locally 
determined action levels. Consult your state cooperative extension service, professional consultants, or 
other qualified authorities to determine the appropriate management, cultural practice and treatment 
threshold levels for the specific crop, geography and diseases. 
 
RESISTANCE MANAGEMENT 
 
For resistance management, Vertisan contains a Group 7 fungicide. Any fungal population may contain 
individuals naturally resistant to Vertisan and other Group 7 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 should be followed. 
To delay fungicide resistance, take one or more of the following steps: 
• Rotate the use of Vertisan or other Group 7 fung icides within a growing season sequence with 
different groups that control the same pathogens. 
• 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 mo dels 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 recommendations for specific crops and pathogens. 
• For further information or to report suspected resistance call 1-800-258-3033. You can also contact 
your pesticide distributor or university extension specialist to report resistance. 
 
TANK MIXTURES 
 
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 Vertisan which may include 
physically compatible pesticides, fertilizers, adjuvants, and/or additives, has not been tested. When 
considering a tank mixture with Vertisan 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 will not be responsible for any crop injury arising from the use of a tank mixture. 
 
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. 
 
Always follow the tank mix instructions of the product label that is most restrictive. Consult a Corteva 
representative or local agricultural authorities for more information concerning tank mixtures.

Vertisan / MSTR / Amend / 04-22-24 Page 7 
 
 
 
APPLICATION INFORMATION 
 
Mixing Instructions 
 
1. Fill clean spray tank ¼ – ½ full of water. 
2. While agitating, add the required amount of Vertisan, continuing agitation until the product is 
completely dispersed. 
3. Continue filling the tank, with agitation, following the sequence listed below in ‘tank mixing 
sequence.’ 
 
Adjuvants 
 
Vertisan fungicide may be used with adjuvants, for example, nonionic surfactants, crop oils, methylated 
seed oils, and blends at typical agricultural use rates for these adjuvants. 
 
Physical Compatibility 
 
Vertisan is physically compatible with many commonly used fungicides, liquid fertilizers, herbicides, 
insecticides, and biological control products. However, since the formulations of products are always 
changing, 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 the 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. 
 
Tank Mixing Sequence 
 
When using in a tank mix, add different formulation types in the sequence indicated below. Allow time for 
complete mixing and dispersion after addition of each product. 
 
1. water-soluble bag 
2. water-dispersible granules 
3. wettable powders 
4. water-based suspension concentrates 
5. water-soluble concentrates 
6. oil-based suspension concentrates 
7. emulsifiable concentrates (Vertisan) 
8. adjuvants, surfactants, and oils 
9. soluble fertilizers

Soilborne/Seedling Disease Control for Cotton, Sugar Beets, and Tuberous and Corm Vegetables 
(Potatoes, Sweet Potatoes, Yams) 
 
Vertisan can provide suppression or control of soilborne diseases when applied early in the growing 
season using specific application methods like pre-plant incorporation prior to planting, or in-furrow or 
banded applications. A single early season application of Vertisan can be made to the soil by one of the 
following methods.

Vertisan / MSTR / Amend / 04-22-24 Page 11 
 
 
Banded application: 
 
Apply Vertisan prior to infection as a directed spray to the soil, using single or multiple nozzles, adjusted 
to provide thorough coverage of the targeted foliage and surrounding soil surface. Band width should be 
limited to 6-8 inches or less. Refer to the Soil Application Rates table. 
 
In-furrow application: 
 
Apply Vertisan as an in-furrow spray in 3-15 gallons of water at planting. Adjust the spray pattern so the 
spray is directed into the furrow on the seed and surrounding soil. The spray pattern should be a 4- to 8-
inch band that is applied to the seed just prior to being covered with soil. Refer to the Soil Application 
Rates table. 
 
Pre-plant incorporation: 
 
Apply Vertisan to the soil in a band or broadcast spray. Incorporate the Vertisan to a depth of 1-2 inches 
using a rototiller, cultivator, rotary hoe, irrigation, or similar methodology. Refer to the Soil Application 
Rates table.

Soilborne/Seedling Disease Control for Tomatoes, Bulb Onions, Peanuts, and Legume Vegetables 
 
Vertisan can provide suppression or control of soilborne diseases when applied early in the growing 
season using specific application methods like pre-plant incorporation prior to planting, or in-furrow, 
banded, or drip applications. A single early season application of Vertisan can be made to the soil by one 
of the following methods. 
 
Banded application: 
 
Apply Vertisan prior to infection as a directed spray to the soil, using single or multiple nozzles, adjusted 
to provide thorough coverage of the targeted foliage and surrounding soil surface. Band width should be 
limited to 6-8 inches or less. Refer to the Soil Application Rates table.

Vertisan / MSTR / Amend / 04-22-24 Page 12 
 
 
In-furrow application: 
Apply Vertisan as an in-furrow spray in 3-15 gallons of water at planting. Adjust the spray pattern so the 
spray is directed into the furrow on the seed and surrounding soil. The spray pattern should be a 4- to 8-
inch band that is applied to the seed just prior to being covered with soil. Refer to the Soil Application 
Rates table. 
 
Pre-plant incorporation: 
 
Apply Vertisan to the soil in a band or broadcast spray. Incorporate the Vertisan to a depth of 1-2 inches 
using a rototiller, cultivator, rotary hoe, irrigation, or similar methodology. Refer to the Soil Application 
Rates table. 
 
Transplant water application: 
 
Transplants should be adequately watered before transplanting. Ensure transplant water volume is 
sufficient to thoroughly wet the root zone. 
 
Use 3-5 fl oz of transplant water per plant. Determine the total water gallonage per acre based on the 
plant population per acre and the fl oz transplant water/plant (3-5 fl oz). Mix the per acre rate of Vertisan 
into the partially filled tank, then completely fill the tank. Continue tank agitation through the transplanting 
process. 
 
Example: 8712 plants/acre x 4 fl oz/ plant = 34,848 fl oz/ acre x 1 gallon/ 128 fl oz = 272.3 gallons/acre 
total transplant water. 
 
Drip application: 
 
Vertisan must be applied in a manner that ensures the product is in the root zone to provide effective 
control of target pests. Vertisan is most effective when it is applied so that the roots are at or near the site 
of application. Refer to the Soil Application Rates table. 
 
Manage irrigation so that significant quantities of Vertisan remain in the root zone. 
 
1.Do not begin applications until after crop emergence in direct seeded crops. 
2.Do not make applications if soil moisture is below the level required for active plant growth. 
3.This product must be applied uniformly in the root zone or poor performance may result. Drip 
tape or emitters must be located within or directly adjacent to the root zone. 
4.The drip system must be properly designed, free of leaks, and operated in a manner that 
provides uniform application of water throughout the field.

Chemigation 
 
Apply Vertisan fungicide only through sprinkler irrigation systems (such as 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 nonuniform 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, shall shut the system down and make necessary adjustments 
should the need arise. 
 
Application Instructions 
 
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 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 should 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. 
3. The pesticide injection pipeline must contain a fu nctional, automatic, quick-closing check valve to 
prevent the flow of fluid back toward the injection pump. 
4. The pesticide injection pipeline must contain a fu nctional, 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.

Vertisan / MSTR / Amend / 04-22-24 Page 39 
 
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 fitted with a system interlock. 
 
Specific Instructions for Sprinkler Irrigation Systems: 
 
1. The system must contain a functional check valv e, vacuum relief valve, and low pressure drain 
appropriately located on the irrigation pipeline to prevent water source contamination from backflow. 
2. The pesticide injection pipeline must contain a fu nctional, automatic, quick-closing check valve to 
prevent the flow of fluid back toward the injection pump. 
3. 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 shut down. 
4. The system must contain functional interlocking controls to automatically shut off the pesticide 
injection pump when the water pump motor stops. 
5. The irrigation line or water pu mp 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. 
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 fitted with a system interlock. 
7. Good agitation is required in the injection tank. 
8. In moving systems, apply specified dosage of Vertisan fungicide as a continuous injection. In nonmoving 
systems inject Vertisan for 15 to 30 minutes at end of cycle. Use the least amount of water possible 
consistent with uniform coverage. 
9. Mix the amount of Vertisan 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. 
10. Stop injection equipment after treatment is completed and continue to operate irrigation equipment until 
all Vertisan is flushed from system.

SPRAY DRIFT MANAGEMENT 
 
Aerial Applications: 
x Do not release spray at a height greater than 10 ft above the vegetative canopy, unless a 
greater application height is necessary for pilot safety. 
x For all applications, applicators are required to use a medium or coarser spray droplet size 
(ASABE S572.1). 
x The boom length must not exceed 65% of the wingspan for airplanes or 75% of the rotor blade 
diameter for helicopters. 
x Applicators must use ½ swath displacement up wind at the downwind edge of the field. 
x Nozzles must be oriented so the spray is directed toward the back of the aircraft. 
x Do not apply when wind speeds exceed 10 miles per hour at the application site. 
x Do not apply during temperature inversions. 
 
Ground Applications: 
x Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet 
above the ground or crop canopy. 
x For all applications, applicators are required to use a medium or coarser spray droplet size 
(ASABE S572.1). 
x Do not apply when wind speeds exceed 10 miles per hour at the application site. 
x Do not apply during temperature inversions. 
 
Boom-less Ground Applications: 
x Applicators are required to use a medium or coarser droplet size (ASABE S572.1) for all 
applications. 
x Do not apply when wind speeds exceed 10 miles per hour at the application site. 
x Do not apply during temperature inversions. 
 
SPRAY DRIFT ADVISORIES 
The interaction of many equipment 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 drift management strategy is to apply the largest droplets which are consistent with pest 
control objectives. 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. 
A droplet size classification system describes the range of droplet sizes produced by spray nozzles. The 
American Society of Agricultural and Biological Engineers (ASABE) provide a Standard that describes droplet 
size spectrum categories defined by a number of reference nozzles (fine, coarse, etc.). Droplet spectra 
resulting from the use of a specific nozzle may also be described in terms of volume mean diameter (VMD). 
Coarser droplet size spectra have larger VMD’s and lower drift potential.

Vertisan / MSTR / Amend / 04-22-24 Page 41 
 
 
CONTROLLING DROPLET SIZE - GROUND APPLICATION 
x Nozzle Type - Select a nozzle type that is designed for the intended application. With most nozzle 
types, narrower spray angles produce larger droplets. The use of low-drift nozzles will reduce drift 
potential. 
x Pressure - The lowest spray pressures recommended for the nozzle produce the largest droplets. 
Higher pressure reduces droplet size and does not improve canopy penetration. When higher flow 
rates are needed, using a higher-capacity nozzle instead of increasing pressure results in the 
coarsest droplet spectrum. 
x Flow Rate/Orifice Size - Using the highest flow rate nozzles (largest orifice) that are consistent with 
pest control objectives reduces the potential for spray drift. Nozzles with higher rated flows produce 
coarser droplet spectra. 
 
CONTROLLING DROPLET SIZE – AIRCRAFT 
x Nozzle Type - Solid stream, or other low drift nozzles produce the coarsest droplet spectra. 
x Number of Nozzles - Using the minimum number of nozzles with the highest flow rate that provide 
uniform coverage will produce a coarser droplet spectrum. 
x Nozzle Orientation - Orienting nozzles in a manner that minimizes the effects of air shear will 
produce the coarsest droplet spectra. For some nozzles such as solid stream, pointing the nozzles 
straight back parallel to the airstream will produce a coarser droplet spectrum than other 
orientations. 
x Pressure – Selecting the pressure that produces the coarsest droplet spectrum for a particular 
nozzle and airspeed reduces spray drift potential. For some nozzle types such as solid streams, 
lower pressures can produce finer droplet spectra and increase drift potential. 
 
BOOM LENGTH (AIRCRAFT), AND APPLICATION HEIGHT 
x Boom Length (aircraft) - Using shorter booms decreases drift potential. Boom lengths are 
expressed as a percentage of an aircraft’s wingspan or a helicopter’s rotor blade diameter. Shorter 
boom length and proper positioning can minimize drift caused by wingtip or rotor vortices. 
x Application Height (aircraft) - Applications made at the lowest height that are consistent with pest 
control objectives and the safe operation of the aircraft will reduce the potential for spray drift. 
x Application Height (ground) - Applications made at the lowest height consistent with pest control 
objectives, and that allow the applicator to keep the boom level with the application site and minimize 
bounce, will reduce the exposure of spray droplets to evaporation and wind, and reduce spray drift 
potential. 
 
WIND 
Drift potential is lowest when applications are made in light to gentle sustained winds (2-10 mph), which are 
blowing in a constant direction. Many factors, including droplet size and equipment type also determine drift 
potential at any given wind speed. AVOID GUSTY OR WINDLESS CONDITIONS. Local terrain can also 
influence wind patterns. Every applicator is expected to be familiar with local wind patterns and how they 
affect spray drift. 
 
TEMPERATURE AND HUMIDITY 
Setting up equipment to produce larger droplets to compensate for droplet evaporation can reduce spray drift 
potential. Droplet evaporation is most severe when conditions are both hot and dry.

Vertisan / MSTR / Amend / 04-22-24 Page 42 
 
SURFACE TEMPERATURE INVERSIONS 
Drift potential is high during a surface temperature inversion. Surface inversions restrict vertical air mixing, 
which may cause small, suspended droplets to remain close to the ground and move laterally in a 
concentrated cloud. Surface 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 and often 
continue into the morning. Mist or fog may indicate the presence of an inversion in humid areas. Inversions 
may also be identified by producing smoke and observing its behavior. Smoke that remains close to the 
ground, or moves laterally in a concentrated cloud under low wind conditions indicates a surface inversion. 
Smoke that moves upward and rapidly dissipates indicates good vertical air mixing. 
 
SHIELDED SPRAYERS 
Shielding the boom or individual nozzles can reduce the effects of wind. However, it is the responsibility of the 
applicator to verify that the shields are minimizing drift potential, and not interfering with uniform deposition of 
the product. 
 
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 
Apply pesticide 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). 
 
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 
Council of Producers and Distributors of Agrotechnology.

Environmental Hazards 
 
This pesticide is toxic to fish, aquatic invertebrates, and oysters. For terrestrial uses: Do not apply directly 
to water, or 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. Drift and runoff may 
be hazardous to aquatic organisms in water adjacent to treated areas. 
 
Surface Water Advisory: This product may impact surface water quality due to runoff of rain water. This 
is especially true for poorly draining soils and soils with shallow ground water. This product is classified as 
having high potential for reaching surface water via runoff several weeks after application. A level, well-
maintained vegetative buffer strip between areas to which this product is applied and surface water 
features such as ponds, streams, and springs will reduce the potential loading of this chemical from runoff 
water and sediment. Runoff of this product will be reduced by avoiding applications when rainfall is 
forecasted to occur within 48 hours. 
 
STORAGE AND DISPOSAL 
 
Do not contaminate water, food, or feed by storage and disposal. 
 
STORAGE: Keep container closed when not in use. Always store pesticides in the original container only, 
away from other pesticides, food, pet food, feed, seed, fertilizers, and veterinary supplies. If a leaky 
container must be contained within another, mark the outer container to identify the contents. Storage 
areas must be locked and secure from vandalism, with precautionary signs posted. The storage area must 
be dry, well
-lit, and well-ventilated. Keep pesticide storage areas clean. Clean up any spills promptly. 
Protect pesticide containers from extreme heat and cold. Store herbicides, insecticides and fungicides in 
separate areas within the storage unit. Place liquid formulations on lower shelves and dry formulations 
above. Maintaining a spill kit and fire extinguisher on hand and having emergency phone numbers posted 
will allow you to be prepared for em
ergencies. If spill cleanup PPE is stored nearby, but outside the 
pesticide storage area, it will be accessible when needed.
