EPA.
Drift and runoff may be hazardous to aquatic organisms in
water adjacent to treated areas.
Groundwater Advisory. This product has properties and
characteristics associated with chemicals detected in
groundwater. These chemicals may leach into groundwater
if used in areas where soils are permeable, particularly
where the water table is shallow.
Surface Water Advisory. DO NOT apply directly to
water, to areas where surface water is present, or to inter-
tidal areas below the mean high water mark. Drift and
runoff may be hazardous to aquatic organisms in water
adjacent to treated areas. DO NOT contaminate water
when disposing of equipment washwater or rinsate. This
product may impact surface water due to runoff of
 rainwater. This is especially true for poorly draining soils
and soils with shallow groundwater. This product is classi-
fied as having high potential for reaching surface water via
runoff for several weeks after application. A level, well-
maintained 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
these chemicals and pyroxasulfone’s degradation product,
[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)-1H-
pyrazol-4-yl]methanesulfonic acid (M1), from runoff water
and sediment. Runoff of this product will be reduced by
avoiding application when rainfall is forecast to occur within
48 hours.
Proper Handling Instructions. This product may not be
mixed or loaded within 50 feet of wells (including aban-
doned wells and drainage wells), sinkholes, perennial or
intermittent streams and rivers, and natural or impounded
lakes and reservoirs. This setback does not apply to prop-
erly capped or plugged abandoned wells and does not
apply to impervious pad or properly diked mixing/loading
areas.
Operations that involve mixing, loading, rinsing, or washing
of this product into or from pesticide handling or applica-
tion equipment or containers within 50 feet of any well are
prohibited unless conducted on an impervious pad con-
structed to withstand the weight of the heaviest load that
may be positioned on or moved across the pad. Such a
pad must be designed and maintained to contain any
product spills or equipment leaks, container or equipment
rinse or washwater, and rainwater that may fall on the pad.
Surface water shall not be allowed to either flow over or
from the pad, which means the pad must be self-
 contained. The pad shall be sloped to facilitate material
removal. An unroofed pad shall be of sufficient capacity to
contain at a minimum 110% of the capacity of the largest
pesticide container or application equipment on the pad. A
pad that is covered by a roof of sufficient size to completely
exclude precipitation from contact with the pad shall have a
minimum containment capacity of 100% of the capacity of
the largest pesticide container or application equipment on
the pad. Containment capacities as described above shall
be maintained at all times. The above specific minimum
containment capacity DOES NOT apply to vehicles when
delivering pesticide shipments to the mixing/loading site.
States may have in effect additional requirements regarding
wellhead setbacks and operational containment.
This product must be used in a manner which will prevent
back-siphoning in wells, spills, or improper disposal of
excess pesticide spray mixture.
Point-source Contamination. To prevent point-source
contamination, DO NOT mix or load this or any other pesti-
cide product within 50 feet of wells (including abandoned
wells and drainage wells), sinkholes, perennial or intermit-
tent streams and rivers, and natural or impounded lakes
and reservoirs. This setback does not apply to properly
capped or plugged abandoned wells and does not apply to
impervious pad or dike mixing/loading areas as described
below.
Mixing, loading, rinsing, or washing operations performed
within 50 feet of a well are allowed only when conducted
on an impervious pad constructed to withstand the weight
of the heaviest load that may be on or move across the
pad. The pad must be self-contained to prevent surface
water flow over or from the pad. The pad capacity must be
maintained at 110% that of the largest pesticide container
or application equipment used on the pad and have suffi-
cient capacity to contain all product spills, equipment or
container leaks, equipment washwater, and rainwater that
may fall on the pad. The containment capacity does not
apply to vehicles delivering pesticide shipments to the
 mixing/loading site. States may have in effect additional
requirements regarding wellhead setbacks and operational
containment.
Care must be taken when using this product to prevent: 
• Back-siphoning into wells
• Spills
• Improper disposal of excess pesticide, spray mixes, or
rinsates
Check valves or anti-siphoning devices must be used on all
mixing equipment.
Physical or Chemical Hazards
DO NOT mix or allow contact with oxidizing agents.
Hazardous chemical reaction may occur.

Product Information
Zidua® PRO herbicide provides both contact burndown
and residual preemergence control of annual grass weeds
and annual broadleaf weeds (including biotypes resistant to
ACCase inhibitors, ALS inhibitors, triazine herbicides, and
glyphosate) (refer to Table 1 for lists of weeds controlled) in
soybean. Refer to Crop-specific Information section for
instructions on herbicide tank mixes.
Make burndown application of Zidua PRO when weeds
are small and actively growing. An adjuvant is required with
Zidua PRO for optimum burndown activity (refer to
Additives section for details). Burndown activity may be
slowed or reduced under cloudy and/or foggy or cooler
weather conditions or when weeds are growing under
drought or other stress conditions. When targeting dense
weed populations and/or larger broadleaf weeds, use high-
er spray volumes. Angling nozzles forward (to 45 degrees)
may improve penetration of denser weed canopies.
Periods of dry weather following application of Zidua PRO
may reduce herbicidal effectiveness. Residual
 preemergence applications of Zidua PRO must be
 activated by at least 1/2 inch of rainfall or sprinkler irrigation
prior to weed seedling emergence. When Zidua PRO is
not activated, a labeled postemergence herbicide or culti-
vation may be needed to control weed escapes.
STORAGE AND DISPOSAL (continued)
Container Handling (continued)
Triple rinse containers too large to shake
(capacity > 5 gallons) as follows: Empty the remaining
contents into application equipment or a mix tank. Fill the
container 1/4 full with water. Replace and tighten clo-
sures. Tip container on its side and roll it back and forth,
ensuring at least one complete revolution, for 30 seconds.
Stand the container on its end and tip it back and forth
several times. Turn the container over onto its other end
and tip it back and forth several times. Empty the rinsate
into application equipment or a mix tank, or store rinsate
for later use or disposal. Repeat this procedure two more
times.
Pressure rinse as follows: Empty the remaining
 contents of all containers into application equipment or
mix tank and continue to drain for 10 seconds after the
flow begins to drip. Hold containers upside down over
application equipment or mix tank, or collect rinsate for
later use or disposal. Insert pressure rinsing nozzle in the
side of the containers and rinse at about 40 PSI for at
least 30 seconds. Drain for 10 seconds after the flow
begins to drip.
Refillable Container. Refill this container with pesticide
only. DO NOT reuse this container for any other purpose.
Triple rinsing the container before final disposal is the
responsibility of the person disposing of the container.
Cleaning before refilling is the responsibility of the refiller.
Triple rinse as follows: To clean the container before
final disposal, empty the remaining contents from this
container into application equipment or mix tank. Fill the
container about 10% full with water. Agitate vigorously or
recirculate water with the pump for 2 minutes. Pour or
pump rinsate into application equipment or rinsate collec-
tion system. Repeat this rinsing procedure two more
times.
When this container is empty, replace the cap and seal all
openings that have been opened during use; return the
container to the point of purchase or to a designated
location. This container must only be refilled with a pesti-
cide product. Prior to refilling, inspect carefully for damage
including cracks, punctures, abrasions, worn-out threads
and closure devices. Check for leaks after refilling and
before transport. DO NOT transport if this container is
damaged or leaking. If the container is damaged, or leak-
ing, or obsolete and not returned to the point of purchase
or to a designated location, triple rinse emptied container
and offer for recycling, if available, or dispose of container
in compliance with state and local regulations.

1 Populations of noted weeds exist that are known to be resistant to Group 2/Group B, Group 14/Group E, and/or
Group 9/Group G (e.g. glyphosate) herbicides. Zidua PRO may not provide full-season control of these herbicide-
resistant biotypes. See the Resistance Management section for practices to manage and minimize the impact of
resistant weeds (e.g. tank mix or alternate with other herbicide modes of action, crop rotation, and mechanical control).

Mode of Action
Zidua® PRO herbicide contains three herbicide active
ingredients. Saflufenacil is a potent inhibitor of
 protoporphyrinogen-oxidase, belonging to herbicide
mode-of-action Group 14 (WSSA)/Group E (HRAC).
Imazethapyr is a potent inhibitor of acetohydroxyacid
 synthase, belonging to herbicide mode-of-action
Group 2 (WSSA)/Group B (HRAC). Pyroxasulfone is a
potent inhibitor of very long chain fatty acid (VLCFA)
 synthesis, belonging to the mode-of-action
Group 15 (WSSA)/Group K3 (HRAC). The
Group 14/Group E and Group 2/Group B herbicides of
Zidua PRO are rapidly absorbed by roots and foliage.
Plant death is the result of membrane damage and inhibi-
tion of the production of branched chain amino acids.
Under active growing conditions, susceptible emerged
weeds usually develop chlorotic and necrotic injury
 symptoms within hours and die within a few days.
Susceptible emerging weed seedlings will usually die as
they reach the soil surface or shortly after emergence. The
Group 15/Group K3 herbicide of Zidua PRO is absorbed
by roots and shoots of weeds following germination. Plant
death is the result of very long chain fatty acid synthesis
inhibition; susceptible weeds typically do not emerge.
Herbicide Resistance Management
While weed resistance to protoporphyrinogen-oxidase-
inhibiting herbicide is relatively infrequent, populations of
resistant biotypes to protoporphyrinogen-oxidase or
 acetohydroxyacid-synthase-inhibiting herbicides are known
to exist. Weed resistance to VLCFA synthesis-inhibiting
herbicides is rare. Resistance management should be part
of a diversified weed control strategy that integrates chemi-
cal, cultural, and mechanical (tillage) control tactics.
Cultural control tactics include crop rotation, proper fertiliz-
er placement, and optimum seeding rate/row spacing.
Consult your local BASF representative, state cooperative
extension service, professional consultants, or other quali-
fied authority to determine appropriate actions if you
suspect resistant weeds. Herbicide resistance manage-
ment practices should be considered and include: 
Chemical Control
1. Following labeled application rate and weed growth
stage instructions.
2. Avoiding repeated applications of herbicides with the
same mode of action.
3. The use of preemergence herbicides that provide soil
residual control of broadleaf and grass weeds to reduce
early season weed competition and allow for timely in-
crop postemergence herbicide applications.
4. Utilizing tank mixes and sequential applications with
other herbicides possessing different sites of action that
are also effective on the target weeds.
5. Using crop rotation so competition, tillage, or herbicides
with alternative modes of action can be used to control
weed escapes.
Scouting and Containment
1. Scouting fields after herbicide application to identify
areas where weed control was ineffective.
2. Controlling weed escapes with herbicides possessing a
different site of action or using a mechanical or cultural
control measure. Weed escapes should not be allowed
to reproduce by seed or to proliferate vegetatively.
3. Contacting your Zidua PRO supplier and/or your local
BASF representative to report weed escapes.
4. Cleaning equipment before moving to a different field to
avoid spread of resistant weeds.
Crop Tolerance
Soybeans are tolerant to Zidua PRO when applied
according to label directions as a preplant to
 preemergence treatment and under normal environmental
conditions. Crop injury may occur under stressful growing
conditions (e.g. seedling disease, extreme hot or cold
weather, excessive moisture, high soil pH, high soil salt
concentration, or drought).
Severe crop injury will result if Zidua PRO is applied
 postemergence (over the top) to soybeans.
Application Instructions
Apply Zidua PRO prior to crop emergence only.
Application Methods and Equipment
Zidua PRO may be applied by ground or air. DO NOT
apply through any type of irrigation system.
Thorough spray coverage is required for optimum weed
control and can be improved with proper adjuvant, nozzle,
and spray volume selection. Use and configure application
equipment to provide an adequate spray volume, an accu-
rate and uniform distribution of spray droplets over the
treated area, and to avoid spray drift to nontarget areas.
Equipment should be adjusted to maintain continuous
 agitation during spraying with good mechanical or bypass
agitation. Avoid overlaps that will increase rates above the
use rates specified in this label.
Zidua PRO may only be applied using water as the spray
 carrier.
Aerial Application Requirements
Water Volume. Use 3 or more gallons of water per acre.
The actual minimum spray volume per acre is determined
by the spray equipment used. Use adequate spray volume
to provide accurate and uniform distribution of spray parti-
cles over the treated area and to avoid spray drift.
The following measures must be followed to reduce the
potential of spray drift to nontarget areas from aerial
 applications: 
1. The distance of the outermost nozzles on the boom
must not exceed 3/4 the length of the fixed wingspan or
90% of rotor blade diameter.
2. Use low-drift nozzles (straight-stream nozzles, D-8 or
larger). DO NOT use nozzles producing a mist droplet
spray.

3. Nozzles must always point backward parallel with the
airstream and never be pointed downward more than
45 degrees.
4. Without compromising aircraft safety, make applications
at a height of 10 feet or less above the crop canopy or
tallest plants.
5. DO NOT apply during periods of temperature inversions
or stable atmospheric conditions.
6. Avoid potential adverse effects to nontarget areas by
maintaining a 30-feet buffer between the point of direct
application and the closest downwind edge of sensi-
tive terrestrial habitats (grasslands, forested areas,
shelter belts, woodlots, hedgerows, riparian areas, and
shrub lands).
Ground Application Requirements
Water Volume. Use 5 or more gallons of water per treated
acre for weed control applications. Thorough spray cover-
age is required for control of emerged broadleaf weeds.
High populations and/or variations in size can prevent ade-
quate spray coverage. Controlling fall-germinated weeds in
the spring (e.g. horseweed/marestail) will also require thor-
ough spray coverage. Use higher spray volumes (e.g. 15 to
20 gallons of water per acre) in these situations to increase
spray coverage and optimize burndown activity.
The following measures must be followed to reduce the
potential of spray drift to nontarget areas from ground
applications: 
1. Apply this product using nozzles which deliver medium-
to-coarse spray droplets as defined by ASAE
standard S-572 and as shown in nozzle manufacturer’s
catalogs. Flat-fan nozzles are recommended for burn-
down applications while flood-jet type nozzles are
recommended for residual soil surface applications.
Nozzles that deliver coarse spray droplets may be used
to reduce spray drift provided spray volume per
acre (GPA) is increased to maintain coverage of target
(i.e. weeds or soil surface). DO NOT use nozzles that
produce fine (e.g. cone) spray droplets.
2. Apply this product only when the potential for drift to
adjacent nontarget areas is minimal (e.g. when the wind
is 10 MPH or less and is blowing away from sensitive
areas). DO NOT apply during periods of temperature
inversions or stable atmospheric conditions.
3. Avoid potential adverse effects to nontarget areas by
maintaining a 13-feet buffer between the application
area and the closest downwind edge of sensitive
 terrestrial habitats (grasslands, forested areas, shelter
belts, woodlots, hedgerows, riparian areas, and shrub
lands).
Cleaning Spray Equipment
Clean application equipment thoroughly by using a strong
detergent or commercial sprayer cleaner according to the
manufacturer’s directions, followed by triple rinsing the
equipment before and after applying this product.
Spray Drift Management
It is the responsibility of the applicator to avoid spray drift at
the application site, especially onto nontarget areas. The
interaction of many equipment-related and weather-related
factors determines the potential for spray drift. The applica-
tor and the grower are responsible for considering all these
factors when making decisions.
The applicator must be familiar with and take into account
the information covered in the following spray drift reduc-
tion advisory information.
Controlling Droplet Size. The most effective way to
reduce drift potential is to apply the largest droplets that
provide sufficient coverage and control.
Volume. Use high flow rate nozzles to apply the highest
practical spray volume. Nozzles with higher rated flows
produce larger droplets.
Pressure. DO NOT exceed the nozzle manufacturer’s
specified pressures. For many nozzle types, lower pressure
produces larger droplets. When higher flow rates are need-
ed, use higher flow rate nozzles instead of increasing
pressure.
Number of Nozzles. Use the minimum number of nozzles
that provide uniform coverage.
Nozzle Type. Use a nozzle type that is designed for the
intended application. With most nozzle types, narrower
spray angles produce larger droplets.
Swath Adjustment. When applications are made with a
crosswind, the swath will be displaced downwind.
Therefore, on the upwind and downwind edges of the field,
the applicator must compensate for this displacement by
adjusting the path of the application equipment (e.g. air-
craft, ground) upwind. Swath adjustment distance should
increase with increasing drift potential (higher wind, smaller
droplets, etc.).
Wind. Drift potential is lowest between wind speeds of 3 to
10 mph. However, many factors, including droplet size and
equipment type, determine drift potential at any given
speed. If applying at wind speeds less than 3 mph, the
applicator must determine if: 
1. Conditions of temperature inversion exist, or 
2. Stable atmospheric conditions exist at or below nozzle
height.
DO NOT make applications into areas of temperature
inversions or stable atmospheric conditions.
NOTE: Local terrain can influence wind patterns. Every
applicator must be familiar with local wind patterns and
how they affect spray drift.
Wind Erosion. Avoid treating powdery, dry or light sandy
soils when conditions are favorable for wind erosion. Under
these conditions, the soil surface should first be settled by
rainfall or irrigation.
11

Additives
For optimum burndown activity of emerged weeds with
Zidua® PRO herbicide, an adjuvant system must be used
that includes the following:
1 MSO-based adjuvant MUST contain at least 60% methy-
lated seed oil. Poor performance may occur with
adjuvants containing less than 60% methylated seed oil.
2 DO NOT use less than 1 pint/A of MSO with low-volume
(< 12.5 gallons per acre) aerial or ground applications.
Use an AMS fertilizer when mixing Zidua PRO with
glyphosate-based herbicides.
DO NOT use nonionic surfactant (NIS) as a substitute for
MSO or poor performance on broadleaf weeds will occur.
When an adjuvant is to be used with this product, BASF
prefers the use of a Chemical Producers and Distributors
Association (CPDA) certified adjuvant.
Tank Mixing Information
Zidua PRO may be tank mixed with one or more regis-
tered herbicide products according to the specific tank
mixing instructions in this label and respective product
labels. Refer to Crop-specific Information section for
details. It is the pesticide user’s responsibility to ensure that
all products in the mixtures are registered for the intended
use. Read and follow the applicable restrictions and limita-
tions and directions for use on all product labels involved in
tank mixing. Users must follow the most restrictive direc-
tions for use and precautionary statements of each product
in the tank mixture.
Tank mixtures with contact herbicides (e.g. carfentrazone,
paraquat) may reduce the burndown activity of
Zidua PRO.
Compatibility Test for Mix Components
Before mixing components, always perform a compatibility
jar test.
1. For 20 gallons per acre spray volume, use 3.3 cups
(800 mL) of water. For other spray volumes, adjust rates
accordingly. Only use water from the intended source at
the source temperature.
2. Add components in the sequence indicated in the mix-
ing order using 2 teaspoons for each pound or
1 teaspoon for each pint of label rate per acre.
3. Always cap the jar and invert 10 cycles between compo-
nent additions.
4. When the components have all been added to the jar, let
the solution stand for 15 minutes.
5. Evaluate the solution for uniformity and stability. The
spray solution should not have free oil on the surface, or
fine particles that precipitate to the bottom, or thick
(clabbered) texture. If the spray solution is not
 compatible, repeat the compatibility test with the addi-
tion of a suitable compatibility agent. If the solution is
then compatible, use the compatibility agent as directed
on its label. If the solution is still incompatible, DO NOT
mix the ingredients in the same tank.
Mixing Order
Shake Zidua PRO container well before use.
Maintain agitation throughout mixing and application until
spraying is completed.
1. Water - Fill tank 1/2 to 3/4 full with clean water and start
agitation.
2. Inductor - If an inductor is used, rinse it thoroughly after
each component has been added.
3. 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.
4. Water-soluble additives (including dry and liquid fertil-
izers ammonium sulfate or urea ammonium nitrate)
5. Water-dispersible products (dry flowables, wettable
powders, suspension concentrates, or suspo-emulsions)
- Add Zidua PRO at this point in the mixing process.
6. Water-soluble products (including glyphosate)
7. Emulsifiable concentrates (including methylated seed
oil adjuvants)
8. Remaining quantity of water
If the spray mixture is allowed to settle for any period of
time, thorough agitation is essential to resuspend the mix-
ture before spraying is resumed. Continue agitation while
spraying.

Use Precautions
• Rainfastness - Zidua® PRO herbicide is rainfast
1 hour after application. Burndown activity may be
reduced if rain or irrigation occurs within 1 hour of
 application.
• Full-rate application of products containing chlorimuron
ethyl, chloransulam-methyl, flumetsulam, or imazaquin in
the same year as Zidua PRO may increase the risk of
injury to sensitive follow crops. Consult the respective
labels of these products for specified uses of these prod-
ucts in combinations.
• When organophosphate or carbamate insecticides are
tank mixed with Zidua PRO, temporary injury may result
to the treated crops.
• Only rotational crops harvested at maturity may be used
for feed or food.
Rotational Crop Restrictions, Crop Rotation,
and Emergency Replanting Intervals
Use Table 2 and its exceptions in the paragraphs following
the table to determine the proper interval between
Zidua PRO application and rotational crop planting. This
interval can be used to determine the acceptable planting
interval for rotational crops as well as replanting after crop
failure (because of environmental factors including drought,
frost or hail, etc.). Be sure to determine the rotational crop
interval for tank mix products and utilize the most restrictive
interval of all products applied.
Table 2. Rotational Crop Planting and 
Emergency Replanting Intervals after an 
Application of Zidua PRO 
a The planting interval for this crop and rates are further
defined in the respective Crop-specific Information
section of this label. Use the longer interval within listed
ranges for indicated crops grown on coarse-textured soils
with organic matter less than or equal to 2.0%.
b Following 40 months after a Zidua PRO application and
before planting any crop not listed elsewhere in the
Rotational Crop Restrictions, Crop Rotation, and
Emergency Replanting Intervals, a successful field
bioassay must be completed. The field bioassay consists

of a test strip of the intended rotational crop planted
across the previously treated field and grown to maturity.
The test strip should include low areas and knolls and
include variations in soil including type and pH. If no crop
injury is evident in the test strip, the intended rotational
crop may be planted the following year. Sugar beet pro-
duction can be reduced when grown in soil conditions
with a pH less than 6.5. If the field is limed to adjust pH
prior to planting rotational crops not listed in Rotational
Crop Restrictions, Crop Rotation, and Emergency
Replanting Intervals, apply the lime at least 12 months
prior to planting the rotational crop.
Use of Zidua
® PRO herbicide in accordance with label
directions is expected to result in normal growth of rota-
tional crops in most situations. However, various
environmental and agronomic factors make it impossible to
eliminate all risks associated with the use of this product
and, therefore, rotational crop injury is always possible.
Exceptions to Crop Rotation Restrictions
Corn Inbred Lines
All corn inbred seed lines may be planted the year following
an application of Zidua PRO. Several seed companies
have tested a wide range of inbreds for sensitivity to
Zidua PRO soil residues and have reported good crop
safety. However, due to the proprietary nature of seed pro-
duction, BASF has not been given access to the inbred
data. Growers are directed to contact the seed company
for information regarding the planting of corn grown for
seed in fields treated with Zidua PRO the previous year.
Because growing conditions, environmental conditions,
and grower practices are beyond the control of BASF, to
the extent of applicable law all risks and consequences
associated with planting seed corn inbreds into fields treat-
ed previously with Zidua PRO shall be assumed by the
user.
Sweet Corn and Popcorn 
(Illinois, Indiana, Iowa, Minnesota, Ohio, Tennessee,
and Wisconsin only)
Sweet corn and popcorn may be planted the year following
an application of Zidua PRO. Some sweet corn and pop-
corn may be injured when planted at less than 18 months
following an application of Zidua PRO. Before planting
sweet corn for processing, contact the processor company
for information regarding the tolerance of sweet corn
planned for fields treated with Zidua PRO the previous
year. DO NOT plant fresh market sweet corn prior to
18 months after Zidua PRO use. Before planting popcorn,
contact the popcorn company for information regarding the
tolerance of popcorn planned for fields treated with
Zidua PRO the previous year. Because growing condi-
tions, environmental conditions, and grower practices are
beyond the control of BASF, to the extent of applicable law
all risks and consequences associated with planting sweet
corn or popcorn into fields treated previously with
Zidua PRO shall be assumed by the user. Stunting and
maturity-delay or other adverse effects may result when
sweet corn or popcorn are planted following Zidua PRO
use.
Certain Vegetable Crops
(Alabama, Delaware, Florida, Georgia, Indiana,
Kentucky, Maryland, New Jersey, North Carolina,
Pennsylvania, South Carolina, and Virginia only)
The following crops may be planted 18 months following
the last application of Zidua PRO: Bahiagrass, cabbage,
 cantaloupe, cucumber, Irish potato, onion, sweet pepper
transplants, sweet potato transplants, tomato transplants
and watermelon.
Field Corn and Field Corn Grown for Seed
(Arizona, Hawaii, Idaho, Montana, Nevada, Oregon,
Utah, Washington, and Wyoming) 
Plant 9.5 months after Zidua PRO application.
Crop-specific Information
This section provides use directions for Zidua PRO. Be
sure to read about product information, mixing, application,
weeds controlled and adjuvant instructions in preceding
sections of the label.
Depending on specific application directions, Zidua PRO
may be applied for burndown control of emerged weeds
and/or residual control of germinating weeds (refer to
Table 1 for list of weeds controlled) before planting
 (preplant/preseed) or after planting but before crop emer-
gence. Depending on the time between Zidua PRO
application and planting, a followup in-crop herbicide appli-
cation may be needed for complete weed control
throughout the growing season.
Thorough spray coverage is required for control of
emerged broadleaf weeds. High populations and/or
 variations in size can prevent adequate spray coverage.
Controlling fall-germinated weeds in the spring 
(e.g. horseweed/marestail) will also require thorough spray
coverage. Use higher spray volumes (e.g. 15 to 20 gallons
of water per acre) in these situations to increase spray cov-
erage and optimize burndown activity. 
Fallow
Zidua PRO may be used as a burndown treatment to con-
trol listed weeds at any time of the year during the fallow
period following crop harvest and before the following crop
is planted (see paragraph below pertaining to rotational
planting intervals).
Application Rate and Timing
Apply Zidua PRO as a broadcast burndown spray at
6.0 fl ozs/A plus required adjuvants (refer to Additives sec-
tion for details). For best product performance, apply
Zidua PRO when broadleaf weeds are small and actively
growing (refer to Table 1 for list of weeds controlled).
Thorough coverage of existing weeds is essential and high-
er spray volumes may be needed for best performance.
Specific rotational crop planting intervals must be observed
between an application of Zidua PRO and planting of the
following crops (see Table 2 for rotational crop planting
intervals).

15
Tank Mixes
Broad-spectrum burndown control of grass weeds and/or
additional broadleaf weeds requires a tank mix with another
herbicide. Zidua
® PRO herbicide may be tank mixed or
applied sequentially with one or more of, but not limited to,
the following herbicide products:
• 2,4-D
• dicamba
• glyphosate
It is the pesticide user’s responsibility to ensure that all
products in the mixtures are registered for the intended
use. Read and follow the applicable restrictions and limita-
tions and directions for use on all product labels involved in
tank mixing. Users must follow the most restrictive direc-
tions for use and precautionary statements of each product
in the tank mixture.
Soybean
Zidua PRO may be applied in the fall and/or in the spring
as a preplant or preemergence burndown application in
conventional, reduced-till, or no-till soybean for weed con-
trol (refer to Table 1 for list of weeds controlled). An
adjuvant system (refer to Additives section for details) is
required for optimum burndown activity.
Application Rate
See Table 3 for application rates of Zidua PRO in soybean
when applied alone, in tank mix, or sequentially.
Table 3. Application Rate (in fl ozs/A) of Zidua PRO in
soybean.
aApply 6 fl ozs/A on fields with high weed pressure, resistant weed popu-
lations, or emerged weeds at the time of application. If less than
6 fl ozs/A is applied under these conditions, weed control may be
 diminished.
State-specific Use in North Dakota and in Minnesota
north of Highway #210. Apply ZIDUA PRO at
4.5 fl ozs/A in the fall or in the spring (see Application
Timing section below for details) for burndown and/or
residual weed control in conventional, reduced-till, or no-till
soybean.
Application Timing
Fall Application
Apply Zidua PRO for burndown and/or residual weed con-
trol after the prior crop is harvested. Applications must be
made prior to first killing frost. Fall applications can be
made to all soil types.
Spring Application
Apply Zidua PRO early preplant through preemergence for
burndown and/or residual weed control prior to crop emer-
gence. A sequential application of Sharpen
® herbicide at
1.0 and 2.0 fl ozs/A may be made with a minimum of
30 and 60 days between applications, respectively.
Soybean Planting Interval
Depending on soil texture and organic matter, an interval
between Zidua PRO application and soybean planting
may be required (see Table 4 and Table 5). These intervals
must be observed prior to planting soybeans or crop injury
may occur.
