GENERAL INFORMATION 
Discover Herbicide controls several grass weed species in all types of wheat (including 
Durum). 
Applied postemergence, Discover 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. Leyel and rate of control depend on weed species, growing conditions, crop 
competition, and coverage. Thorough coverage of the plants is essential for consistent 
control. 
ROTATIONAL CROP RESTRICTIONS 
The following crops may be planted at the specified interval following application of 
Discover Herbicide. 
Crop Rotational Interval 
Wheat (including Durum) Oda~s 
All other crops 30 days 
WEEDS CONTROLLED 
Discover Herbicide controls wild oat, volunteer oat, green foxtail, yellow foxtail, giant 
foxtail, barnyardgrass, canarygrass, Persian darnel, volunteer corn, and Italian (annual) 
ryegrass. 
Although Discover Herbicide does not control broad leaf weeds, it can be tank mixed with 
a wide range of broad leaf herbicides to provide broad spectrum one-pass weed control. 
See the section entitled Tank Mixes of Discover Herbicide with Broadleaf Weed 
Herbicides. Herbicides not approved on this label for tank mixing with Discover 
Herbicide may be applied sequentially. Always apply Discover Herbicide first and allow at 
least 4 days after application of Discover Herbicide before applying these herbicides 
sequentially. 
MANAGEMENT OF RESISTANT WEEDS 
Discover Herbicide is a Group 1 Herbicide (ACCase mode of action). Some naturally 
occurring populations of wild oat, green foxtail and Italian (annual) ryegrass have been 
identified as resistant to herbicides with the ACCase mode of action (herbicides with the 
same mode of action as Discover Herbicide, such as: Achieve®, Assure® II, Axial®, 
Fusilade®, Fusion®, Hoelon®, Poast®, Prism®, Puma®, and Select®). 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 
)D/3l

-7-
) 
be attributed to adverse weather conditions or improper application methods. If 
resistance is suspected, contact your local Syngenta representative for assistance. 
The following practices will delay selection for resistant populations of weeds: 
• Apply postemergence herbicides to small, actively growing weeds. 
• Ensure that good spray coverage is achieved with proper spray volumes and 
calibrated equipment. 
• Use the full label rate of product. 
• Avoid tank mixes that may cause antagonism and reduced weed control. 
• Where possible, avoid the repeated use of herbicides with the same mode of action 
(i.e~, same group number) in successive seasons either in cereal crops or rotational 
crops. 
• Use a diverse crop/fallow rotation to extend the range of available herbicides and 
agronomic practices. 
• Use cultivation, fertilizer regimens, seeding rates and row widths that enhance crop 
competitiveness. 
• Prevent weed escapes from producing seed either in the crop or during fallow periods. 
APPLICATION PROCEDURES 
TIMING OF APPLICATION 
Apply Discover Herbicide to all types of wheat (including Durum) from the 2-leaf stage to 
pre-boot stage. Do not make an application to winter wheat in the fall. Refer to the Crop 
Use Directions section for grazing and harvest restrictions. 
Precaution: Do not apply to a crop that is stressed by conditions such as frost, low 
fertility, drought, flooding, disease damage, or insect damage, as crop injury may result. 
Wheat is more susceptible to injury when exposed to temperatures below 40 OF during 
the period 48 hours before or after Discover Herbicide application. 
For optimum results, apply Discover Herbicide to actively growing weeds. 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 re-tillering may 
occur if application is made during prolonged conditions of stress. Optimum weed control 
will be obtained if application of Discover Herbicide is delayed until the conditions of 
stress have ended and weeds are once again actively growing. An early application will 
maximize crop yields by reducing weed competition. Weeds emerging after application 
will not be controlled.

GROUND AND AERIAL APPLICATION PROCEDURES 
For best accuracy, calibrate the sprayer before use. 
Ground Applications 
Spray Nozzles - BO° or 110° flat fan nozzles are recommended for optimum spray 
coverage. 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 45° 
for optimum coverage of grass weeds. Follow the nozzle manufacturer's 
recommendations for pressure and screens. Do not use flood or hollow cone type 
nozzles. 
Pump - Must have capacity to maintain pressure (35-40 psi) and to maintain the product 
suspension through tank agitation. A centrifugc;il pump is recommended with an agitation 
rate of 20 gals./minute/1 00 gals. tank size. Agitation must be maintained during mixing 
and spraying.

-10-
Screens - Use a screen or strainer with 16-mesh or coarser on the suction side of the 
pump. Do not place a screen 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. 
Water Volume - Use an application rate of 5-10 gals. of water per acre. Always use a 
minimum of 10 gals. of water per acre under dry conditions or dense weed populations 
and when treating Persian darnel or Italian (annual) ryegrass. . 
Adjuvants - Always use the DSV Adjuvant included in the Discover Herbicide case. 
Other adjuvants should not be used. See Mixing Instructions. 
Pressure - 35-40 psi at the nozzles. Lower pressure may be used with extended range 
or low pressure nozzles. 
Good weed coverage with the spray mixture is essential for optimum weed control results. 
Observe sprayer nozzles frequently during the spraying operation to ensure that the spray 
pattern is uniform. Avoid large spray overlaps which result in excessive rates in the 
overlap areas. Also, avoid application under conditions when uniform coverage cannot 
be obtained or when excessive spray drift may occur. To reduce spray drift, do not apply 
under windy conditions., Allow adequate distance between target area and desirable 
vegetation to prevent drift to nontarget areas. Boom height for broadcast over-the-top 
application should be based upon the free-standing height of the crop, not height above 
the soil surface, and should be at least 12 inches above the crop. 
Aerial Applications 
Apply Discover Herbicide in water using a minimum spray volume of 3 gals'/A. Use a 
minimum of 5 gals'/A under dry conditions or dense weed populations and when treating 
Persian darnel or Italian (annual) ryegrass. Include DSV Adjuvant in the spray mixture 
(see Mixing Instructions). Use the recommended rates for DSV Adjuvant given in the 
Product and Adjuvant Use Rates table. Do not apply DSV Adjuvant at concentrations 
greater than 2% v/v in the spray mix as crop injury may result. Avoid application under 
conditions where uniform coverage cannot be obtained or where excessive spray drift 
may occur. Make applications at a maximum height of 10ft. above the crop with low-drift 
nozzles at a maximum pressure of 40 psi and wind speed not exceeding 10 mph to help 
assure accurate application within the target area. 
RECOMMENDATIONS TO AVOID SPRAY DRIFT 
Aerial Drift Management 
. 
Avoiding spray drift at the application site is the responsibility of the applicator. The 
interaction of many equipment- and weather-related factors determine the potential for 
spray drift. The applicator and the grower are responsible for considering all these factors 
when making decisions.

The following drift management requirements must be followed to avoid off-target drift 
movement from aerial applications to agricultural field crops. These requirements do not 
apply to forestry applications, public health uses, or to applications using dry formulations. 
1. The distance of the outermost nozzles on the boom must not exceed % the length 
of the wingspan or rotor. 
2. Nozzles must always point backward parallel with the air stream and never be 
pointed downward more than 45 degrees. 
Where states have more stringent regulations,' they should be observed. 
The applicator should be familiar with and take into account the information covered in 
the Aerial Drift Reduction Advisory Information. 
AERIAL DRIFT REDUCTION ADVISORY INFORMATION 
Information on Droplet Size 
The most effective way to reduce drift potential is to apply large droplets. The best drift 
management strategy is to apply the largest droplets that provide sufficient coverage and 
control. Applying larger droplets reduces drift potential, but will not prevent drift if 
applications are made improperly, or under unfavorable environmental conditions (see 
Wind, Temperature and Humidity, and Temperature Inversions). 
Controlling Droplet Size 
• 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 recommended pressures. For 
many nozzle types, lower pressure produces larger droplets. When higher flow rates 
are needed, use higher flow rate nozzles instead of increasing pressure. 
• Number of Nozzles - Use the minimum number of nozzles that provide uniform 
coverage. 
• Nozzle Orientation - Orienting nozzles so that the spray is released parallel to the 
airstream produces larger droplets than other orientations and is the recommended 
practice. Significant deflection from horizontal will reduce droplet size and increase 
drift potential. 
• Nozzle Type - Use a nozzle type that is designed for the intended application. With 
most nozzle types, narrower spray angles produce larger droplets. Consider using

-12-
low-drift nozzles. Solid stream nozzles oriented straight back produce the largest 
droplets and the lowest drift. 
Boom Length 
For some use patterns, reducing the effective boom length to less than % of the wingspan 
or rotor length may further reduce drift without reducing swath width. 
Application Height 
Applications should not be made at a height greater than 10ft. above the top of the 
largest plants, unless a greater height is required for aircraft safety. Making applications 
at the lowest height that is safe reduces exposure bf droplets to evaporation and wind. 
Swath Adjustment 
When applications are made with a crosswind, the swath will be displaced downward. 
Therefore, on the up and downwind edges of the field, the applicator must compensate 
for this displacement by adjusting the path of the aircraft upwind. Swath adjustment 
distance should increase with increasing drift potential (higher wind, smaller drops, etc.). 
Wind 
Drift potential is lowest between wind speeds of 2-10 mph. However, many factors, 
including droplet size and equipment type, determine drift potential at any given speed. 
Application should be avoided below 2 mph due to variable wind direction and high 
inversion potential. Note: Local terrain can influence wind patterns. Every applicator 
should be familiar with local wind patterns and how they affect spray drift. 
Temperature and Humidity 
When making applications in low relative humidity, set up equipment to produce larger 
droplets to compensate for evaporation. Droplet evaporation is most severe when 
conditions are both hot and dry. 
Temperature Inversions 
Applications should not occur during a temperature inversion because drift potential is 
high. Temperature inversions restrict vertical air mixing, which causes small suspended 
droplets to remain in a concentrated cloud. This cloud can move in unpredictable 
directions due to the light variable winds common during inversions. Temperature 
inversions are characterized by 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 ground fog; 
however, if fog is not present, inversions can also be identified by the movement of 
smoke from a ground source or an aircraft smoke generator. Smoke that layers and

-13-
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. 
Sensitive Areas 
The pesticide should only be applied 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). 
Avoid all direct or indirect contact (such as spray drift) of Discover Herbicide with crops 
other than those recommended for treatment on this label, since injury may occur. 
Chemigation: Do not apply this product through any type of irrigation system.
