Precautionary Statements
Hazards to Humans and Domestic Animals
CAUTION. Harmful if inhaled or swallowed. Avoid contact 
with skin or clothing. Avoid breathing spray mist. Wash 
hands thoroughly with soap and water after handling and 
before eating, drinking, chewing gum, using tobacco or 
using the toilet. Remove and wash contaminated clothing 
before reuse.
Personal Protective Equipment (PPE)
Applicators and other handlers must wear:
• Long-sleeved shirt and long pants,
• Chemical-resistant gloves made of barrier laminate or 
butyl rubber ≥ 14 mils or nitrile rubber ≥ 14 mils or 
 neoprene rubber ≥ 14 mils or polyvinyl chloride (PVC) 
≥ 14 mils or viton ≥ 14 mils, and
• Shoes plus socks
User Safety Requirements
Follow the manufacturer’s instructions for cleaning/ 
maintaining PPE. If no such instructions for washables 
exist, use detergent and hot water. Keep and wash PPE 
separately from other laundry. Remove and wash contami-
nated clothing before reuse. Discard clothing and other 
absorbent materials that have been drenched or heavily 
contaminated with this product’s concentrate. DO NOT 
reuse them.
USER SAFETY RECOMMENDATIONS
Users should:
• 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
Terrestrial Use
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 dis-
posing of equipment washwaters or rinsate. DO NOT pour 
equipment washwaters or rinsate down into a natural drain 
or water body. DO NOT exceed the maximum seasonal 
use rate or the total number of applications of Versys
TM 
insecticide per season. To reduce the potential for devel-
oping insecticide-resistance, rotate to an insecticide with a 
different mode of action.
Non-target Organisms
Versys is toxic to aquatic invertebrates. Drift and run-off 
from treated areas may be hazardous to aquatic organ-
isms in water adjacent to treated areas. DO NOT apply 
when weather conditions favor drift from treated areas.
Although Versys is not acutely toxic to bees, use at 
the maximum single application rate may have some 
short-term behavioral effects on adult bees, but is 
not expected to have long-term impacts on bees 
and overall colony health.
Ground Water Advisory
Afidopyropen and a degradate of concern may leach into 
ground water if used in areas where soils are permeable, 
particularly where the water table is shallow.
Surface Water Advisory
Versys may impact surface water quality due to run-off of 
rain water. This is especially true for poorly draining soils 
and soils with shallow ground water. Versys is classified 
as having a medium-high potential for reaching both sur-
face water and aquatic sediment via run-off for several 
weeks to months after application. A well-maintained veg-
etative buffer strip between areas to which this product is 
applied and surface water features such as ponds, 
streams and springs, as required under the Directions 
For Use, will reduce the potential for loading of 
FIRST AID

Product Information
VersysTM insecticide contains the technical active ingre-
dient Inscalis® insecticide, commonly known as 
afidopyropen. When used as directed, Versys provides 
knockdown and residual control of listed pests including 
aphids, whiteflies, and Asian citrus psyllid within the crops 
included on this label. Versys is active against whitefly 
egg, early instar, and adult life stages. Additionally, some 
scale pests are controlled or suppressed by Versys. 
 Versys acts quickly to inhibit feeding. While Versys does 
demonstrate translaminar activity, and moves toward plant 
leaf margins, it is not fully systemic. Therefore, good cover-
age of plant surfaces will result in the most effective 
control. Use of sufficient water volume is important, espe-
cially under dense canopy to ensure best performance.
Versys can be used effectively in Integrated Pest 
 Management (IPM) and resistance management 
programs. 
Mode of Action
The active ingredient in Versys is classified by the IRAC 
(Insecticide Resistance Action Committee) as target-site-
of-action Group 9D insecticide, a chordotonal organ 
TRPV (Transient Receptor Potential Vanilloid) channel 
modulator. Versys disrupts the gating of TRPV (Transient 
Receptor Potential Vanilloid) channel complexes in 
 chordotonal stretch receptor organs of insects. This dis-
rupts feeding and other behaviors in target insects. 
Repeated use of insecticides with similar modes of action 
can lead to the buildup of resistant pest populations.
Resistance Management
For resistance-management, Versys contains a 
Group 9D insecticide. Any insect population may contain 
individuals naturally resistant to Versys and other 
Group 9D insecticides. The resistant individuals may 
dominate the insect population if this group of insecticides 
are used repeatedly in the same fields. Appropriate resis-
tance management strategies should be followed. To 
reduce the potential for developing insect resistance, 
rotate to an insecticide with a different mode of action. 
Monitor treated pest populations for resistance develop-
ment. Read product label before applying any insecticide 
and follow label directions.
To delay insecticide resistance, take the following steps:
• Rotate the use of Versys or other Group 9D insecti-
cides within a growing season, or among growing 
seasons, with different groups that control the same 
pests. Avoid application of more than the maximum sea-
sonal use rate or the total number of consecutive sprays 
of Versys per season.
• Use tank mixtures with insecticides from a different 
group that are equally effective on the target pest when 
such use is permitted. DO NOT rely on the same mix-
ture repeatedly for the same pest population. Consider 
any known cross-resistance issues (for the targeted 
pests) between the individual components of a mixture. 
In addition, consider the following recommendations 
 provided by the Insecticide Resistance Action Commit-
tee (IRAC):
- Individual insecticides selected for use in mixtures 
should be highly effective and be applied at the rates at 
which they are individually registered for use against the 
target species.
- Mixtures with components having the same IRAC 
mode of action classification are not recommended for 
insect resistance management.
- When using mixtures, consider any known 
 cross-resistance issues between the individual compo-
nents for the targeted pest(s).
- Mixtures become less effective if resistance is already 
developing to one or both active ingredients, but they 
may still provide pest management benefits.
- The insect resistance management benefits of an 
insecticide mixture are greatest if the two components 
have similar periods of residual insecticidal activity. Mix-
tures of insecticides with unequal periods of residual 
insecticide activity may offer an insect resistance man-
agement benefit only for the period where both 
insecticides are active.
• Adopt an integrated pest management program for 
insecticide/acaricides use that includes scouting, uses 
historical information related to pesticide use, crop rota-
tion, record keeping, and which considers cultural, 
biological and other chemical control practices.
• Monitor after application for unexpected target pest sur-
vival. If the level of survival suggests the presence of

6
resistance, consult with your local university specialist or 
certified pest control advisor.
• Contact your local extension specialist or certified crop 
advisors for any additional pesticide resistance manage-
ment and/or IPM recommendations for the specific site 
and pest problems in your area.
• For further information or to report suspected resistance 
contact BASF representatives at 1-800-832-HELP (4357).
Application Instructions
For maximum effectiveness, apply VersysTM insecticide 
at the first sign of pest presence before the populations 
increase to damaging levels. Application should be timed 
to coincide with locally recommended treatment threshold 
levels for the target pest population. 
Versys is rainfast one (1) hour after an application 
has dried.
Apply Versys in a sufficient volume of water to 
ensure thorough coverage of foliage.
Ground Application
Apply to foliage using properly calibrated ground sprayers. 
Thorough and uniform spray will result in the most effective 
control. Apply Versys in minimum water volume per acre 
as indicated in Crop-specific Application Instructions 
table. Applications made at lower volumes may result in 
less than thorough coverage especially in dense canopy 
crops. Slower activity and/or less control may result if 
spray coverage is limited.
Aerial Application
Thorough coverage is required to obtain optimum insect 
control when aerial applications are employed. Avoid appli-
cations under conditions when uniform coverage cannot 
be obtained or when spray drift may occur. Use no less 
than the minimum allowed gallons of spray solution per 
acre. Refer to Crop-specific Application Instructions 
table. For all crops, thorough coverage is required for opti-
mum pest insect control. DO NOT apply when conditions 
favor drift from target area. DO NOT apply directly to 
humans or animals.
Sprinkler Irrigation System Application
Versys may be applied using sprinkler irrigation systems 
on specific crops as noted in the Crop-specific 
 Application Instructions table.
Application Through Sprinkler Irrigation Systems
This product can be applied through sprinkler irrigation 
systems including center pivot, lateral move, end tow, side 
(wheel) roll, traveler, big gun, solid set, or hand move irriga-
tion 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 injec-
tion equipment. In continuous moving systems, inject this 
product-water mixture continuously, applying the labeled 
rate per acre for that crop. DO NOT exceed 1/4 inch 
(6,788 gallons) per acre. In stationary or noncontinuous 
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 sprin-
kler 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 effec-
tiveness, or illegal pesticide residues in the crop can result 
from nonuniform distribution of treated water. Thorough 
coverage of foliage is required for good control. Maintain 
good agitation during the entire application period. If you 
have questions about calibration, you should contact a 
state extension service specialist, equipment manufactur-
ers or other experts.
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 contami-
nation 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 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.
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, 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 the supervision of 
the responsible person, shall shut the system down and 
make necessary adjustments should the need arise.
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

7
 pesticide introduction. As an option to the RPZ, the 
water from the public water system should be dis-
charged 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 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-

7. DO NOT apply when wind speed favors drift beyond the 
area intended for treatment.
Spray Drift Reduction Management
DO NOT apply when wind speed favors drift beyond the 
area intended for treatment. The interaction of many equip-
ment and weather-related factors determine the potential 
for spray drift. The applicator is responsible for considering 
these factors when making application decisions. Avoiding 
spray drift is the responsibility of the applicator.
Importance of Droplet Size. An important factor influ-
encing drift is droplet size. Small droplets (<150 to 
200 microns) drift more than large droplets. Within typical 
equipment specifications, applications should be made to 
deliver the largest droplet spectrum that provides sufficient 
control and coverage. Use only medium or coarser spray 
nozzles (for ground and aerial applications) according to 
ASAE (S572) definition for standard nozzles. In conditions 
of low humidity and high temperatures, applicators should 
use a coarser droplet size.
Ground Applications. Wind speed must be measured 
adjacent to the application site on the upwind side, imme-
diately prior to application. For ground boom applications, 
apply using a nozzle height of no more than 4 feet above 
the ground or crop canopy. For airblast applications, turn 
off outward pointing nozzles at row ends and when spray-
ing the outer two (2) rows. To minimize spray loss over the 
top in orchard applications, spray must be directed into the 
canopy.
Aerial Applications. The spray boom should be mount-
ed on the aircraft to minimize drift caused by wing tip 
vortices. The minimum practical boom length should be 
used, and must not exceed 75% of the wing span or 
80% rotor diameter. Flight speed and nozzle orientation 
must be considered in determining droplet size. Spray 
must be released at the lowest height consistent with pest 
control and flight safety. DO NOT release spray at a height 
greater than 10 feet above the crop canopy unless a great-
er height is required for aircraft safety. When applications 
are made with a cross-wind, the swath will be displaced 
downwind. The applicator must compensate for this dis-
placement at the downwind edge of the application area 
by adjusting the path of the aircraft upwind. Making appli-
cations at the lowest height that is safe reduces the 
exposure of the droplets to evaporation and wind.
Wind Speed Restrictions. Drift potential increases at 
wind velocities of less than 3 mph (due to inversion poten-
tial) or more than 10 mph. However, many factors, 
including droplet size, canopy and equipment specifica-
tions determine drift potential at any given wind speed. 
Only apply this product if the wind direction favors 
 on-target deposition. DO NOT apply when wind velocity 
exceeds 15 mph and avoid gusty and windless conditions. 
Risk of exposure to sensitive aquatic areas can be reduced 
by avoiding applications when wind direction is toward the 
aquatic area.
Restrictions During Temperature Inversions. 
DO NOT make ground applications during temperature 
inversions. Drift potential is high during temperature inver-
sions. Temperature inversions restrict vertical air mixing, 
which causes small suspended droplets to remain close to 
the ground and move laterally in a concentrated cloud. 
Temperature inversions are characterized by stable air and 
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 mist or 
ground fog; however, if fog is not present, inversions can 
also be identified by the movement of smoke from a 
ground source. Smoke that layers and moves laterally near 
the ground surface in a concentrated cloud (under low 
wind conditions) indicates an inversion, while smoke that 
moves upward and rapidly dissipates indicates good verti-
cal mixing.
Cleaning Spray Equipment
Before application, start with clean, well-maintained appli-
cation equipment. Following spray application, thoroughly 
clean all application equipmen t. Drain application equip-
ment of any excess product. Thoroughly rinse application 
equipment 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 equipment near wells, water 
sources, or desirable vegetation.

Additives and Tank Mixing Information
Shake container well before use.
VersysTM insecticide can be tank mixed with most rec-
ommended fungicides, insecticides, liquid fertilizers, 
adjuvants, and additives.
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 direc-
tions 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.
Under certain conditions or when recommended under 
the Crop-specific Application Instructions , adjuvants 
can improve the performance of Versys. However, all vari-
eties and cultivars have not been tested with the solo 
product or all possible tank mix combinations. Local con-
ditions can also influence crop tolerance and may not 
match those under which BASF has conducted testing. 
Physical incompatibility, reduced pest control, or crop inju-
ry can result from mixing Versys with other products.
Before using any tank mix (fungicides, insecticides, liquid 
fertilizers, adjuvants, and additives), test the combination 
on a small portion of the crop to be treated (including plant 
cultivars) to ensure that a phytotoxic response will not 
occur as a result of application. Always follow the most 
restrictive label use directions.
Evaluate for crop response 3 to 7 days before making an 
application to the entire crop.
When an adjuvant is to be used with this product, BASF 
recommends the use of a Chemical Producers and 
 Distributors Association certified adjuvant.
Consult a BASF representative or local agricultural authori-
ties for more information concerning additives.
Mixing Order
Make sure each component is thoroughly mixed and sus-
pended before adding tank mix partners. If the spray 
mixture is allowed to settle for any period of time, thorough 
agitation is essential to resuspend the mixture before 
spraying is resumed. Maintain constant agitation during 
application. 
Shake Versys container well before use.
 1. Water - Begin by filling a thoroughly clean sprayer tank 
1/2 to 3/4 full of clean water. 
 2. Agitation - Maintain constant agitation throughout 
mixing 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-soluble additives (including dry and liquid fer-
tilizers such as ammonium sulfate or urea ammonium 
nitrate).
 6. Water-dispersible products (dispersible concen-
trates, dry flowables, wettable powders, other 
suspension concentrates, or suspo-emulsions). Add 
Versys at this point in the mixing.
 7. Water-soluble products
 8. Emulsifiable concentrates (such as oil concentrates 
when applicable)
 9. Water-soluble additives (such as AMS or UAN when 
applicable)
10. Remaining quantity of water
