3.0 PRODUCT INFORMATION
Discover NG Herbicide is a systemic postemergence herbicide for the control of wild oat,
volunteer oat, green foxtail, yellow foxtail, giant foxtail, barnyardgrass, canarygrass, Persian
darnel, volunteer corn, and Italian (annual) ryegrass in all varieties of wheat (including
Durum). Discover NG Herbicide is rapidly absorbed by weed foliage and translocated to the
growing points where it inhibits the acetyl CoA carboxylase (ACCase) enzyme. Susceptible
weed species generally stop growing within 48 hours, turn yellow within one to three weeks,
and are completely controlled within three to five weeks. Level and rate of control depend on
weed species, growing conditions, crop competition, and coverage.
Although Discover NG Herbicide does not control broadleaf weeds, it can be tank mixed with
a wide range of broadleaf herbicides to provided broad spectrum one-pass weed control. .
Discover NG Herbicide applied alone is rainfast 30 minutes after application.
3.1 Weed Resistance Management Practices
CLODINAFOP-PROPARGYL GROUP 1 HERBICIDE
Discover NG Herbicide is a Group 1 Herbicide (ACCase-inhibitor mode of action). Some
naturally occurring grass weed populations have been identified as resistant to herbicides
with the ACCase-inhibitor mode of action. Selection of resistant biotypes, through repeated
use of these herbicides in the same field, may result in control failures. A resistant biotype
may be present if poor performance cannot be attributed to adverse weather conditions or
improper application methods.
Contact your local Syngenta representative, retailer, crop advisor or extension agent to
determine if weeds resistant to this mode of action are present in your area. If resistant
biotypes have been reported, use the full labeled rate of this product, apply at the labeled
timing, and tank-mix with a different mode of action product so there are multiple effective
modes of application for each suspected resistant weed.
3.1.1 PRINCIPLES OF HERBICIDE RESISTANT WEED MANAGEMENT
Scout and know your field
• Know weed species present in the field to be treated through scouting and field
history. An understanding of weed biology is useful in designing a resistance
management strategy. Ensure the weed management program will control all weeds
present.
U.S. Label
Discover NG Herbicide
Page 8
• Fields should be scouted prior to application to determine species present and growth
stage. Always apply this herbicide at the full labeled rate and correct timing for the
weeds present in the field.
Utilize non-herbicidal practices to add diversity
• Use diversified management tactics such as cover crops, mechanical weed control,
harvest weed seed control, and crop rotation as appropriate.
Use good agronomic practices, start clean and stay clean
• Use good agronomic practices that enhance crop competitiveness.
• Plant into weed-free fields ut ilizing tillage or an effective burndown herbicide for control
of emerged weeds.
• Sanitize farm equipment to avoid spreading seed or vegetative propagules prior to
leaving fields.
Difficult to control weeds
• Fields with difficult to control weeds should be planted in rotation with crops that allow
the use of herbicides with an alternative mode of action or different management
practices.
• Difficult to control weeds may require sequential applications, such as a broad
spectrum preemergence herbicide followed by one or more postemergence herbicide
applications. Utilize herbicides containing different modes of action effective on the
target weeds in sequential applications.
Do not overuse the technology
• Do not use more than two applications of th is or any other herbicide with the same
mode of action in a single growing season unless mixed with an herbicide with a
different mode of action which provides overlapping spectrum for the difficult to control
weeds.
Scout and inspect fields following application
• Prevent an influx of weeds into the fi eld by controlling weeds in field borders.
• Scout fields after application to verify that the treatment was effective.
• Suspected herbicide resistant weeds ma y be identified by these indicators
• Failure to control a weed species normally controlled by the herbicide at the
dose applied, especially if control is achieved on adjacent weeds;
• A spreading patch of non-controlled plant s of a particular weed species; and
• Surviving plants mixed with controll ed individuals of the same species.
• Report non-performance of this product to your Syngenta retailer, Syngenta
representative, or call 1-866-Syngent(a) (866-796-4368). If resistance is suspected
U.S. Label
Discover NG Herbicide
Page 9
ensure weed escapes are controlled using an herbicide with an effective mode of
action and/or use non-chemical means to prevent further seed production.
Prevent weed escapes before, during, and after harvest
• Do not allow weed escapes to produce seed or vegetative structures such as tubers or
stolons which contribute to spread and survival. Consider harvest weed seed
management and control weeds post-harvest to prevent seed production.
4.0 APPLICATION DIRECTIONS
4.1 Methods of Application
Applications with Discover NG Herbicide alone or in tank mixtures are permitted by ground
and by air. Post-emergence applications are allowed as specified in Section 9.0 unless
restricted in Section 7.0.
4.2 Application Equipment
x Configure spray equipment to provide accurate and uniform coverage of the target area and
minimize potential for spray drift.
x To ensure accuracy, calibrate sprayer before each use.
x For information on spray equipment and calibration, consult spray equipment
manufacturers and/or state recommendations.
x All ground and aerial application equipment must be properly maintained.
x 80º or 110º flat fan nozzles are reco mmended for optimum spray coverage.
x Use a screen or strainer with 16-mesh or coarser on the suction side of the pump. Do not
place in the recirculation line unless using a roller or piston pump. Use 50-mesh or
coarser screens between the pump and boom, and at the nozzles.
x Pumps must have the capacity to maintain sp ray pressure (35-40 psi) and to maintain
suspension through tank agitation. A centrifugal pump is recommended with an agitation
rate of 20 gal/minute/100 gal tank size. Agitation must be maintained during mixing and
spraying.
4.3 Application Volume and Spray Coverage
x Thorough spray coverage of target weed s is essential for consistent control.
x For ground application, apply the spray mixtur e in a volume of 5-10 gal per acre. Use 10
gal/A under dry conditions or dense weed populations. Volumes greater than 10 gal/A
should be avoided as reduced grass control may occur.
x Nozzles must be uniformly spaced along the boom to provide accurate and uniform
coverage. Point the nozzles forward in the direction of travel at an angle of 45º for
optimum coverage of grass weeds. Observe sprayer nozzles frequently during the
spraying operation to ensure that the spray pattern is uniform.
x Boom height for broadcast over-the-top application should be based upon the free-
standing height of the crop, not the height above the soil surface, and should be at least
12 inches above the crop.
U.S. Label
Discover NG Herbicide
Page 10
x For aerial applications, apply in a minimum spray volume of 3 gal/A. Use a minimum of 5
gal/A under dry conditions or dense weed populations. Avoid application under conditions
where uniform coverage cannot be obtained or where excessive spray drift may occur.
x For aerial applications, apply at a maximum height of 10 ft above the crop with low-drift
nozzles at a maximum pressure of 40 psi to help assure accurate application within the
target area.

Page 11
tank mixing.
4.4.3 TANK-MIX COMPATIBILITY
x Conduct a jar test using a 1 pt to 1 qt contai ner with lid by adding water or other intended
carrier such a liquid fertilizer to the jar.
x Next, add the appropriate amount of pesticide s(s) or tank-mix partner(s) in their relative
proportions based on recommended label rates. Add tank-mix components separately in
the order described in the tank-mixing section, Section 4.4.4. After each addition, shake
or stir gently to thoroughly mix.
x After all ingredients have been added, put the lid on the jar, tighten and invert the jar 10
times to mix.
x After mixing, let the mixture stand 15 –30 minutes and then examine for signs of
incompatibility such as obvious separation, large flakes, precipitates, gels or heavy oily
film on the jar.
x If the mixture remains mixed or can be remix ed readily, it is physically compatible and can
be used.
x If the mixture is incompatible, repeat the test using a compatibility agent at the
recommended rate. Or, if applicable, slurry dry formulations in water before adding to the
jar. If incompatibility is still observed after following these procedures, do not use the
mixture.
x After compatibility testing is complete, dispos e of any pesticide wastes in accordance with
the Storage and Disposal section, Section 9.0, of this label.

5.0 ROTATIONAL CROPS
5.1 Rotational Crop Restrictions
The following crops may be planted at the specified interval following application of Discover
NG Herbicide.
Crop Plant-Back Interval
Wheat (including Durum) 0 days
All other crops 30 days
6.0 Cover Crops
A cover crop can be an important tool for the overall farm cropping system. Cover crops are
planted for conservation purposes, soil erosion control, soil health improvement, water quality
improvement and weed management. A cover crop can be a single crop or a combination of
crops, including grasses and/or broadleaf crops.
After harvest of a Discover NG Herbicide treated crop, planting of a cover crop is allowed
provided the cover crop is not grazed or fed to livestock nor harvested for food. Terminate
the cover crop through natural causes such as frost or intentional termination by herbicide
application, crimping, rolling, tillage or cutting.
All possible cover crops or cover crop combinations have not been tested for tolerance to this
product. Before planting the cover crop, determine the level of tolerance for the intended
cover crops by conducting a field bioassay. Refer to Section 6.1 for instructions on how to
conduct a field bioassay.
6.1 Field Bioassay for Cover Crops
A field bioassay is a method of determining if herbicide residues are present in the soil at
concentrations high enough to adversely affect crop growth.
Conduct the field bioassay by planting several strips of the desired cover crop across the field
which has been previously treated with Discover NG Herbicide. Plant the cover crop strips
U.S. Label
Discover NG Herbicide
Page 13
perpendicular to the direction of the product application. Locate the strips so that all the
different field conditions are encountered, including differences in field terrain, soil texture,
organic matter, pH, and drainage.
If the cover crop does not show adverse effects such as crop injury and/or stand reduction,
the field can be planted to this cover crop. If injury and/or stand reduction are visible, wait
two to four weeks for further herbicide degradation to occur and repeat the bioassay.
Alternatively, select a different cover crop and repeat the bioassay. Only plant cover crops
that show acceptable tolerance in the field bioassay.
7.0 Restrictions and Precautions
7.1 Use Restrictions
x DO NOT apply this product through any type irrigation system.
7.2 Use Precautions
x Avoid large spray overlaps which result in excessive rates in the overlap areas.
x Avoid application under conditions when uniform coverage cannot be obtained or when
excessive spray drift may occur.
x Do not allow spray to drift to adjacent fields seeded to crops other than wheat.
x To reduce spray drift, do not apply under windy conditions.
x Allow adequate distance between target area and desirable vegetation to prevent drift to
non-target areas.
x For further guidance and instructions on how to minimize spray drift, refer to Section 7.3.
7.3 Spray Drift Management
x As with all crop protection products, it is important to avoid off-target movement onto
adjacent land or crops, as even small amounts may injure sensitive plants.
x To reduce spray drift, the following spray drift management requirements must be
followed.
x The interaction of many equipment and we ather-related factors determines the potential
for spray drift.
x The applicator and grower must consider the interaction of equipment and weather-
related factors to ensure that the potential for drift to sensitive non-target plants is
minimal.
x This pesticide may only be applied when the potential for drift to adjacent sensitive areas
(e.g., residential areas, bodies of water, non-target plants) is minimal (i.e., when the wind
is blowing away from the sensitive area).
x Consult with local and State agricultural authorities for information regarding avoiding or
minimizing spray drift.
x Avoid all direct or indirect contact (such as spray drift) of Discover NG Herbicide with
crops other than those recommended for treatment on this label, since injury may occur.
U.S. Label
Discover NG Herbicide
Page 14
7.3.1 AERIAL APPLICATIONS
x Do not release spray at a height greater than 10 feet above the vegetative canopy, unless
a greater application height is required for pilot safety.
x The boom length must not exceed 75% of th e wingspan for airplanes or 90% of the rotor
diameter for helicopters.
x Applicators must use 1/2 swath displacement upwind at the downwind edge of the field.
x Nozzles must be oriented so the spray is directed toward the back of the aircraft.
x For applications prior to the emergence of crops and target weeds, applicators are
required to use a coarse or coarser droplet size (ASABE S572.1).
x For all other applications, applicators are requ ired to use a medium or coarser droplet size
(ASABE S572.1).
x Do not apply during temperature inversions.
7.3.2 GROUND BOOM APPLICATIONS
x Apply with the nozzle height recommended by the manufacturer, but no more than 4 feet
above the ground or crop canopy unless making a turf, pasture, or rangeland application,
in which case applicators may apply with a nozzle height no more than 4 feet above the
ground.
x For applications prior to the emergence of crops and target weeds, applicators are
required to use a Coarse or coarser droplet size (ASABE S572.1).
x For all other applications, applicators are required to use a Medium or coarser droplet size
(ASABE S572.1).
x Do not apply during temperature inversions.
7.4 Spray Drift Advisories
x AVOIDING SPRAY DRIFT AT THE APPLICATION SITE IS THE RESPONSIBILITY OF
THE APPLICATOR.
x BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.
7.4.1 IMPORTANCE OF DROPLET SIZE
x An effective way to reduce spray drift is to apply large droplets.
x Use the largest droplets that provide target pest control.
x 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.
7.4.2 CONTROLLING DROPLET SIZE - AIRCRAFT
x Adjust Nozzles - Follow nozzle manufacturer’s recommendations for setting up nozzles.
Generally, to reduce fine droplets, nozzles should be oriented parallel with the airflow in
flight.

Page 15
7.4.3 CONTROLLING DROPLET SIZE – GROUND BOOM
x 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.
x Pressure - Use the lowest spray pressure recommended for the nozzle to produce the
target spray volume and droplet size.
x Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider
using nozzles designed to reduce drift.
7.4.4 BOOM HEIGHT – GROUND BOOM
x Use the lowest boom height that is compatib le with the spray nozzles that will provide
uniform coverage.
x For ground equipment, the boom should re main level with the crop and have minimal
bounce.
7.4.5 RELEASE HEIGHT - AIRCRAFT
x Higher release heights increase th e potential for spray drift.
x When applying aerially to crops, do not release spray at a height greater than 10 ft above
the crop canopy, unless a greater application height is necessary for pilot safety.
7.4.6 SHIELDED SPRAYERS
x Shielding the boom or individual nozzles can reduce spray drift.
x Consider using shielded spraye rs. Verify that the shields are not interfering with the
uniform deposition of the spray on the target area.
7.4.7 TEMPERATURE AND HUMIDITY
x When making applications in hot and dry cond itions, use larger droplets to reduce effects
of evaporation.
7.4.8 TEMPERATURE INVERSIONS
x Drift potential is high during a temperature inversion.
x Temperature inversions are characterized by increasing temperature with altitude and are
common on nights with limited cloud cover and light to no wind.
x 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.
x 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.
x Avoid applications during temperature inversions.

Page 16
7.4.9 WIND
x Drift potential generally increases wit h wind speed. AVOID APPLICATIONS DURING
GUSTY WIND CONDITIONS.
x Applicators need to be familiar with local wi nd patterns and terrain that could affect spray
drift.
7.4.10 WINDBLOWN SOIL PARTICLES
x Discover NG Herbicide has the potential to move off-site due to wind erosion.
x Soils that are subject to wind erosion usually have a high silt and/or fine to very fine sand
fractions and low organic matter content.
x Other factors which can affect the movement of windblown soil include the intensity and
direction of prevailing winds, vegetative cover, site slope, rainfall, and drainage patterns.
x Avoid applying Discover NG Herbicide if prevailing local conditions may be expected to
result in off-site movement.

(including Durum) from the 2-
leaf stage to pre-boot stage.
For optimum results, apply Discover
NG Herbicide to actively growing
weeds.
An early application will maximize
crop yields by reducing weed
competition.
For Wild Oat, Volunteer Oat, and
Canarygrass, apply at the 1 to 6
stage on main stem, prior to
emergence of the 4th tiller.
For Green Foxtail, Yellow Foxtail,
Giant Foxtail, apply at the 1 to 5 leaf
stage on main stem. For optimum
control, apply prior to emergence of
the 3rd tiller.
For Persian Darnel, Italian (Annual)
Ryegrass, Barnyardgrass,
Volunteer Corn, apply at the 1 to 5
leaf stage on main stem. For
optimum control, apply before
tillering.
Weed control can be reduced or
delayed under conditions of stress,
such as drought, heat, insufficient
fertility, flooding, and prolonged cool
temperatures.
Grass escapes or retillering may
occur if application is made during
prolonged conditions of stress.
Optimum weed control will be
obtained if application is delayed until
conditions of stress have ended and
weeds are once again actively
growing.
