PRODUCT INFORMATION , 
SILVERADOTM Wild Oat Herbicide is used as a foliar spray in wheat for the control of wild oat and wild mustard. This ~r~d~~t' requires 
the addition of an adjuvant as specified in this label. 
/ ! ' , ' I 
ENVIRONMENTAL AND BIOLOGICAL ACTIVITY 
SILVERADOTM Wild Oat Herbicide is absorbed through the foliage of plants, rapidly inhibiting growth of susceptible weeds. Visual 
symptoms progress from yellowing to necrosis of the growing point and eventual plant death. 
2

(' ( 7 
Best weed control is obtained when SILVERADOTM Wild Oat Herbicide is applied to young actively growing weeds in vigorously 
growing wheat that will shade competitive weeds. Abnormal environmental conditions (excess soil moisture or drought, extreme cold 
weather) can influence crop tolerance and herbicidal activity and may cause temporary damage to the crop or reduce levels of weed 
control. This may result in weed stunting, rather than weed death. However, weed competition will be greatly reduced, and should 
permit normal crop development. 
APPLICATION TIMING 
Weed Application Timing 
SILVERADOTM Wild Oat Herbicide is a postemergence herbicide and best results are obtained when applications are made to young 
actively growing weeds. For wild oat control, the weed application timing is from 1-leaf to the 2-tiller stage of growth. See weed tables 
for appropriate application timing and weed size. Treat heavy weed infestations before they become competitive with the crop. 
Wheat Timing 
Apply SILVERADOTM to wheat from emergence up to the jointing stage of growth. 
SPRAY ADDITIVES 
SILVERADOTM Wild Oat Herbicide is a water dispersible granule that does not include an adjuvant. An adjuvant must be tank mixed 
with SILVERADOTM according to the guidelines as described in the Mixing Order section. 
Application of SILVERADOTM Wild Oat Herbicide must include either a methylated seed oil, MSO basic blend or a basic blend type 
adjuvant. Use a high quality methylated seed oil (MSO) with 10% emulsifier or greater at 1.5 ptiA. An ammonium nitrogen fertilizer may 
be added to the methylated seed oil to improve weed control, particularly under adverse conditions. Use only spray grade quality urea 
ammonium nitrogen fertilizer (28-0-0 or 30-0-0 or 32-0-0 at 1 - 2 qtlacre) or ammonium sulfate fertilizer (21-0-0-24 at 1.5 - 3 Ibsfacre). 
When ammonium nitrogen fertilizer is used in tank mixture with SILVERADOTM, transient leaf burn may occur. Do not use ammonium 
nitrogen fertilizers without either a methylated seed oil, MSO basic blend or basic blend type adjuvant. 
Do not use additives that alter the spray solution below 6.0 pH. Best results are obtained at spray solution pH of 6.0 - 8.0. 
Methylated Seed Oil (MSO) 
Apply a methylated seed oil in tank mixture with SILVERADOTM at a rate of 1.5 pt fA in spray volumes of 10 gallons or more per acre. 
In special circumstances when SILVERADOTM Wild Oat Herbicide is tank mixed with a pesticide that restricts the addition of a 
methylated seed oil, a non-ionic based basic blend adjuvant should be used instead. 
MSO Basic Blend Adjuvants 
Apply MSO Basic Blend adjuvants at a rate of 2% vfv in spray solution volumes of 10 gallons or more per acre. Use a minimum of 1.5 
pt fA of MSO Basic Blend in tank mixture with SILVERADOTM. 
Basic Blend Adjuvants 
Select a Basic Blend adjuvant that is a formulated combination of a non-ionic surfactant or a methylated oil and a nitrogen source. Use 
a Basic Blend adjuvant at 1 % vfv or 0.8 - 1.6 ptiA depending on water carrier volume per acre in tank mixture with SILVERADOTM. 
Select the appropriate amount of basic blend adjuvant per acre depending on local conditions but do not apply less Basic Blend 
adjuvant than 0.8 ptiA. 
APPLICATION METHODS 
Uniform, thorough spray coverage is important to achieve consistent weed control. For best results, use nozzles that deliver 200 - 350 
micron size droplets providing optimum spray coverage. Do not use flood-jet nozzles, controlled droplet application equipment, or cone 
nozzles. 
Ground Application 
SILVERADOTM Wild Oat Herbicide can be applied broadcast in 10 - 20 gallons of water per acre. For weed control in dense weed 
canopies, use 15 to 20 gallons of water per acre. Weed infestations should be treated before they become competitive t'llito,+he crop. 
o ( 
The use of SO-degree or 11 O-degree flat-fan nozzles is highly recommended for optimum spray coverage and canopy pJ'lcll(ation. Use 
a spray pressure of 35 to 40 pounds per square inch (measured at the nozzle). Use screens that are 50 mesh or larger. ~ 0 ( , 
Do not apply this product through any type of irrigation system.

MIXING INSTRUCTIONS 
SILVERADOTM Wild Oat Herbicide must be applied with clean and properly calibrated equipment. Prior to adding SILVERADOTM Wild 
Oat Herbicide to the spray tank, ensure that the spray tank, filters and nozzles have been thoroughly cleaned. 
Mixing Order 
1. Fill the tank 1/4 to 1/3 full of water. 
2. While agitating, add the required amount of SILVERADOTM Wild Oat Herbicide. 
3. Continue agitation until the SILVERADOTM is fully dispersed, at least 5 minutes. 
4. Once SILVERADOTM is fully dispersed, maintain agitation and continue filling tank with water. It is important that SILVERADOTM is 
fully mixed with water before adding any other material. 
5. As the tank is filling, add the required amount of spray adjuvant (methylated seed oil or basic blend adjuvant) and ammonium 
nitrogen fertilizer, if desired. Add additional pesticide tank mix partner, if desired. 
6. Continue agitation during herbicide application to ensure uniform spray coverage. If the mixture is not continuously agitated, 
settling may occur. If settling occurs, thoroughly re-agitate spray solution for at least 10 minutes before application. Use spray 
solution within 24 hours after mixing. 
RE-SUSPENDING WG PRODUCTS IN SPRAY SOLUTION 
Like other Water Dispersible Granules or suspension concentrates (SC's), SILVERADOTM Wild Oat Herbicide will settle if left standing 
without agitation. If the spray solution is allowed to settle for one hour or more, re-agitate the spray solution for a minimum of 10 
minutes before application. 
COMPATIBILITY 
If SILVERADOTM Wild Oat Herbicide is to be tank mixed with other herbicides, compatibility should be tested prior to n:i)dh'g~ cTo test for 
compatibility, use a small container and mix a small amount (0.5 to 1 qt) of spray solution, combining all ingredients in the same ratio as 
the anticipated use. If any indications of physical incompatibility develop, do not use this mixture for spraying. : Indications of 
incompatibility usually occur within 5-15 minutes after mixing. Read and follow the label of each tank mix J}r'v'duct used /9~ , , ,

TANK CLEANUP PROCEDURE 
1. Drain the tank completely, and then wash out tank, boom and hoses with clean water. Drain again. 
2. Half fill the tank with clean water and add ammonia (Le., 3% domestic ammonia solution) at a dilution rate of 1 % (Le., 1 gallon of 
domestic ammonia for every 100 gallons of rinsate). Complete filling of the tank with water. Agitate/recirculate and flush through 
boom and hoses. Leave agitation on for 10 minutes. Drain tank completely. 
3. Repeat step 2. 
4. Remove nozzles and screens and soak them in a 1 % ammonia solution. Inspect nozzles and screens and remove visible residues. 
5. Flush tank, boom, and hoses with clean water. 
6. Inspect tank for visible residues. If present, repeat step 2. 
SPRAY DRIFT MANAGEMENT 
SILVERADOTM Wild Oat Herbicide is not volatile. Damage to sensitive crops can occur as a result of spray drift. Spray drift can be 
managed by several application factors and by spraying under the appropriate climatic conditions. Consequently, avoidance of spray 
drift is the responsibility of the applicator and grower. 
SENSITIVE AREAS: The pesticide must only be applied when the potential for drift to adjacent sensitive areas (e.g., residential areas, 
bodies of water, known habitats for threatened or endangered species, non-target crops) is minimal (e.g., when wind is blowing away 
from the sensitive areas). 
Avoiding spray drift at the application site is the responsibility of the applicator and grower. 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. 
Do not apply under circumstances where possible drift to unprotected persons or to food, forage, or other plantings that might be 
damaged or crops thereof rendered unfit for sale, use or consumption can occur. 
The following drift management requirements must be followed to avoid off-target drift movement from aerial applications to agricultural 
field crops. 
1. The distance of the outer most nozzles on the boom must not exceed 3/4 the length of the wingspan or rotor. 
2. Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 degrees. 
3. All aerial and ground application equipment must be properly maintained and calibrated using appropriate carriers. 
Where states have more stringent regulations, they shall be observed. The applicator should be familiar with and take into account the 
information covered in the 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 below). 
Uniform, thorough spray coverage is important to achieve consistent weed control. Select nozzles and pressure that deliver MEDIUM 
spray droplets as indicated in nozzle manufacturer's catalogs and in accordance with ASAE Standard S-572. 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 
weeds. 
CONTROlliNG DROPLET SIZE: 
• Volume - Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated flows produce larger 
droplets. ( ( , L 
(( « 
• Pressure - Do not exceed the nozzle manufacturer's recommended pressures. For many nozzle types lower pre~sp(~ 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. ~ , , ~ . :

and the lowest drift. ~ , , , : I 
BOOM LENGTH: 
For some use patterns, reducing the effective boom length to less than 3/4 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 10 feet 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 of droplets to evaporation and wind. 
For ground boom applications, apply with nozzle height no more than 4 feet above the ground or crop canopy. 
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. 
For all non-aerial applications, wind speed must be measured adjacent to the application site, on the upwind side, immediately prior to 
application. 
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. Avoid spraying during conditions of low humidity and/or high 
temperatures. 
TEMPERATURE INVERSIONS: 
Do not make aerial or ground applications into areas of temperature inversions 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 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.

The active ingredient in this product, mesosulfuron-methyl is a Group 2 Herbicide based on the mode of action classification system of 
the Weed Science Society of America. Any weed population may contain plants naturally resistant to Group 2 herbicides. Weeds 
resistant to these herbicides may be effectively managed utilizing another herbicide from a different Group and/or by using cultural or 
mechanical practices. However, a herbicide mode of action classification by itself may not adequately address specific weeds that are 
resistant to specific herbicides. Consult your local company representative, state cooperative extension service, professional 
consultants or other qualified authorities to determine appropriate actions for treating specific resistant weeds.

Best Management Practices 
SILVERADOTM Wild Oat Herbicide inhibits the ALS enzyme system. Repeated use of herbicides with the same mode of action allows 
resistant weeds to spread. Proactively implementing diversified weed management programs may delay the development of resistant 
weeds. Diversified programs include the use of multiple herbicides with different modes of action with overlapping weed spectrums as 
well as the utilization of cultural weed control practices, such as tillage. 
• Use labeled rates of herbicides and carefully follow the directions for use 
• Scout fields after a herbicide application to facilitate early detection of weed shifts and/or weed resistance 
• Implement measures to avoid allowing weeds to reproduce by seed or proliferate vegetatively 
• Clean equipment between sites and avoid movement of plant material between sites to retard the spread of potentially 
resistant weed seed. 
PRECAUTIONS AND RESTRICTIONS FOR USE 
• Use adjuvants as specified on this label with SILVERADOTM Wild Oat Herbicide. 
• Do not apply SIL VERADOTM to crops undersown with grass and legume species. 
• SILVERADOTM is rainfast 4 hours after application to most weed species. Rainfall within 4 hours may result in reduced weed 
control. Weed control may be reduced if application is made in the presence of heavy dew, fog, and mist/rain. 
Applications should be made to actively growing weeds. Weed control may be reduced when weeds are under stress due to 
severe weather conditions, drought, very cold temperatures, etc. Weed control may be reduced if the herbicide application is made 
under dry, dusty conditions - especially in the wheel track areas. 
• Do not use liquid nitrogen fertilizer solutions such as 28-0-0 or 30-0-0 or 32-0-0 as the carrier when applying SILVERADOTM. 
• 
Varieties of wheat (including Durum) may differ in their response to herbicides. It is recommended that you consult your state 
experiment station, university or local extension agent as to specific varietal sensitivity to any herbicides. If no information is 
available, limit the initial use to a small area. 
Do not make more than one application of SILVERADOTM in one growing season. 
Do not apply more than 2.25 ozlAcre of SILVERADOTM in one growing season. 
Do not apply more than 0.053 pounds of mefenpyr-diethyl per acre per year. 
Do not apply when wind causes drift to off-site vegetation as injury may occur. Small amounts of SILVERADOTM via drift or tank 
contamination can cause severe damage to crops other than wheat. Careful management of spray drift and tank cleanout is 
required. c ( ( ( 
Do not apply SILVERADOTM within 30 days of harvesting wheat forage, 50 days for hay, and 55 days for grain and ~t[~~.c 
Do not apply SILVERADOTM in tank mixture with malathion, mancozeb or methyl parathion as unacceptable crop ph~10t()xicity may 
occur. ( t ( (
