Extreme herbicide is the leader of a category of value-added herbicides created specifically for maximum weed control in Roundup Ready soybeans. Extreme attacks newly emerged grasses and broadleaf weeds with the knockdown power of glyphosate and keeps them down with the trusted residual control of Pursuit herbicide, while clearing Roundup Ready soybeans of early-season, yield-robbing weed competition.
Directions For Use
It is a violation of federal law to use this product in a manner inconsistent with its labeling.
DO NOT apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your state or tribe, consult the agency responsible for pesticide regulation.
This label must be in the possession of the user at the time of herbicide application.
Application Instructions
DO NOT apply when winds are gusty, under low-level inversion conditions or under other conditions that favor drift. Maintain appropriate buffer zones between treated fields and adjacent desirable vegetation. Exposed leaves or other green tissue may be damaged or killed by drift from Extreme . Severe injury or plant death may result if Extreme contacts foliage of desirable plants. To prevent injury to desirable plants and crops, DO NOT allow spray drift to occur.
DO NOT allow the herbicide solution to drift onto desirable vegetation. Very small amounts of drift may cause injury or death to desirable crops or plants. The likelihood of injury from use of this product increases when winds are gusty. The risk of injury from this product increases when wind direction is constantly changing or during inversion conditions or other weather conditions that favor drift. Avoid applications using high spray pressure and high speed. These contribute to conditions that favor small spray droplets and drift.
When Extreme is used in combination with another herbicide, refer to the respective label for rates, methods of application, proper timing, weeds controlled, restrictions and precautions. Always use in accordance with the more restrictive label restrictions and precautions. DO NOT exceed label dosages. DO NOT mix Extreme with any product containing a label prohibiting such mixtures.
To avoid injury to sensitive crops, drain spray equipment used for Extreme applications and thoroughly clean with water before applying other products.
Drift Control Additives
Drift control additives may be included in either ground or aerial applications. When a drift control agent is used, read and carefully observe the precautionary statements and all other information appearing on the additive label.
Ground Application
Uniformly apply with properly calibrated ground equipment in 10 or more gallons of water per acre. A spray pressure of 20 to 40 psi is recommended.
To ensure thorough coverage, use a minimum of 20 gallons of water per acre when applying Extreme to minimum or no-till crops. Use higher gallonage for fields with dense vegetation or heavy crop residues. Adjust the boom height to ensure proper coverage of weed foliage (according to the manufacturer’s recommendation). Use only flat-fan nozzle tips for postemergence applications.
Avoid overlaps when spraying.
Aerial Application
Uniformly apply with properly calibrated aerial equipment in 5 or more gallons of water per acre.
When applied postemergence, the addition of a nonionic surfactant AND fertilizer solution are required for optimum weed control. Apply nonionic surfactant (NIS) at 0.125% volume to volume (v/v) of spray solution AND ammonium sulfate (AMS) at 2.5 lbs/A. See Postemergence instructions in Application Information section.
Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment-related and weather-related factors determines 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 3/4 the length of the wingspan or rotor.
2. Nozzles must always point backward parallel with the airstream and never be pointed downward more than 45 degrees.
Observe more stringent state regulations, if applicable.
The applicator should be familiar with and take into account the information covered in the aerial drift reduction advisory information presented below.
SOYBEANS
Rate: Apply Extreme at 2.25 pts/A. One gallon of Extreme will treat 3.6 acres at this rate.
Critical comments:
DO NOT apply Extreme herbicide postemergence to non-Roundup Ready soybeans. DO NOT exceed 2.25 pts/A per season.
CORN
Rate: Extreme herbicide may be applied at 3.0 pts/A as a fall or spring burndown application prior to planting Clearfield corn and/or prior to using Lightning in-crop to Clearfield corn
Critical comments:
DO NOT apply Extreme to emerged Clearfield corn or crop injury will occur. DO NOT apply Counter 15G insecticide to preplant Clearfield corn acres treated with Extreme or crop injury can occur. DO NOT plant wheat in the same year as application of Extreme followed by Lightning unless at least 10 inches of rainfall or overhead irrigation has occurred between application of Extreme and wheat planting.
ALFALFA
Rate: Apply Extreme at a broadcast rate of 2.2 to 4.4 pts/A postemergence only to seedling or established Roundup Ready alfalfa grown for forage, hay, or seed.
Critical comments:
DO NOT apply Extreme at more than 3.0 pts/A in North Dakota or Minnesota north of Highway #210. DO NOT apply more than 3.0 pts/A of Extreme to Roundup Ready alfalfa during the last year of the stand. Maximum Seasonal Use Rate - A maximum of 0.094 lb ae/A of imazethapyr (4.4 pts/A of Extreme ) per year may be applied to Roundup Ready alfalfa. Preharvest Interval (PHI) - DO NOT feed, graze, or harvest Roundup Ready alfalfa for 30 days following an application of Extreme to Roundup Ready alfalfa.
Mixing Instructions
Burndown or postemergence applications of Extreme herbicide require the addition of a surfactant AND fertilizer.
Surfactant
Use a nonionic surfactant containing at least 80% active ingredient. Apply the surfactant at 1 pint per 100 gallons of spray mixture (0.125% volume/volume of the spray mixture). Use only surfactants approved for application to growing crops.
Fertilizer
Include a fertilizer in the spray solution. Add spray grade ammonium sulfate at 8.5 to 17 lbs per 100 gallons of spray solution. Use the higher rate when weeds are under moisture or temperature stress.
Mixing Order
1. Water - Begin by agitating a thoroughly clean sprayer tank 1/2 full with clean water.
2. Agitation - Maintain continuous and constant agitation throughout.
3. Fertilizer
4. Extreme - Mix thoroughly.
5. Surfactant
6. Remaining quantity of water

Replace and tighten closures. 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 into application equipment or mix tank and continue to drain for 10 seconds after the flow begins to drip. Hold container 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 container and rinse at about 40 PSI for at least 30 seconds. Drain for 10 seconds after the flow begins to drip.
