# EnlistTM Corn

The Enlist trait c onfers tolerance to 2,4

- D and quizalofop , and will be stacked with the glyphosate tolerance trait in Enlist corn hybrids. This offers growers the benefits of tolerance to in

- crop applications of Enlist Duo and other Dow AgroSciences’ Authorized Herbicide Products to reduce weed competition while using herbic ides with multiple modes of action as part of its management practices.
In addition to herbicide tolerance, some Enlist hybrids will conta in Bt traits that confer insect protection

. If you purchase hybrids that contain Bt traits , you must also follow applicable Insect Resistance Management requirements. C onsult the appropriate PUG for refuge requirements

.


## Volunteer Control

Enlist corn is tolerant to 2,4

- D, glyphosate and quizalofop herbicides. It is recommended that a “

- dim” herbicide

, such as Select ® (c lethodim) or Poast Plus ® ( se t hoxydim)

, be used to control volunteer Enlist corn in soybeans.



## Coexistence

Corn is a naturally cross

- pollinated crop, and a small amount of corn pollen movement to nearby fields is not uncommon. You can take steps to reduce the occurrence and extent of undesired pollen movement. These steps include: mainta ining a non

- corn buffer between cornfields containing biotech nology traits and conventional cornfields; not growing corn with biotech traits upwind (based on the prevaili ng wind directions) of other corn fields ; and discussing your cropping plans with your neighbors in advance.


## Crop and Grain Marketing Stewardship

## Weed Control with Enlist Duo Herbicide

The lower use rates given on the Enlist Duo label will be satisfactory for young, succulent growth of sensitive weed species. For less sensitive species and under conditions where control is more difficult, the higher use rates will be needed. Apply Enlist Duo TM when weeds are young and actively growing, per the label directions.

The product label for Enlist Duo contains the directions and recommendations for use over Enlist crops including application equipment requirements, product use directions, restrictions and precautio ns, weed management information, and other product information.



## The Program Approach

A program approach

, including Enlist Duo herbicide

, aids in the management of herbicide resistance, reduces weed competition during critical crop growth stages and improves the overall consistency of weed control . It eliminates competition from a broad spectrum of early season grass and broadleaf weeds. The mode of action classification system of the Weed Science Society of America (WSSA) lists 2,4

- D as a Group 4 g rowth regulator herbicide (synthetic auxin) and glyphosate as a Group 9 herbicide (inhibitor of ESPP synthase).

The recommended weed control program for Enlist TM corn is a PRE application herbicide product containing at least two non

- Group 4/ Group 9 modes of action, followed by a POST application of Enlist Duo herbicide. If a second POST application of Enlist Duo is required, it must occur at least 12 days after the first application, per the product label.

## Application

Read and follow product label, as well as follow state and local requirements related to application of pesticides. Apply Enlist DuoTM herbicide only with properly calibrated ground application equipment using appropriate carriers. 

### Boom Height To minimize spray drift potential, use the minimum nozzle height recommended by the nozzle manufacture r based on configuration of the spray boom and spray angle of the nozzle tip

. 

### Spray Volume Use a spray volume of 10

- 15 gallons or more per acre for grou nd equipment and apply with calibrated ground equipment. Do not apply less than 10 gallons total spray volume per acre. Where applicable, state regulations specifying minim um spray volumes must be observed.
In general, increase spray volume as crop canopy , height and weed density increase to obtain adequate spray coverage. 

### Nozzle Selection Proper spray nozzle selection plays a critical part in minimizing the potential for physical drift. Use low drift nozzles, according to the American Society of Agricultu ral and Biological Engineers ( ASABE ) S

- 572 standard, that produce a coarse to very coarse spray and are designed for herbicide application. Ultra coarse droplet sizes may result in decreased weed control and increased crop injury.

Nozzle selection is a process that maximizes product performance by managing the interaction between application volume (GPA), nozzle flow rate (GPM), nozzle type, operating pressure, travel speed (MPH), nozzle spacing (W) and droplet size category. The fo llowing are examples that produce a coarse to very coarse spray with the appropriate settings.

Temperature an d H umidity
When making applicat ions 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. 

### Susceptible Plants
Do not apply under circumstances where spray drift may occur to food, forage, or other plantings that might be damaged or crops thereof rendered unfit for sale, use or consumption. Avoid contact of herbicide with foliage, green stems, exposed non

- woody roots of crops, desirable plants and trees because severe inj ury or destruction may result. Small amounts of spray drift that may not be visible may injure susceptible broadleaf plants. Before making an application, please refer to your state’s sensitive crop registry (if available) to identify any commercial sp ecialty or certified organic crop s that may be located nearby. Commercially grown tomatoes and other fruiting vegetables (EPA crop group 8), cucurbits (EPA crop group 9), and grapes are particularly sensitive to drift from this product. Do not apply when w ind direction favors off

- target movement onto these crops.


### Setbacks

Setbacks for Enlist DuoTM herbicide are directional

, meaning they would only apply downwind of the spray application

.

Setback Distances Upwind of Sensitive Areas * : [ P ending EPA approval of the product label ]

Setback Distance * : Allow setbacks (buffer zones) upwind of sensitive area (e.g., residential areas, bodies of water, known habitat for threatened or endangered species, and sensitive non

- target crops other than those listed above ) according to the following:

Wind Speed (mph) Spray Boom <24 Inches Above Canopy (ft) Spray Boom >24 Inches Above Canopy (ft) <5 15 30 5

– 10 40 80 10

– 15 80 150

* If a coarse or very coarse droplet classification cannot be maintained, an upwind setback of 250 feet from sensitive areas must be observed.


# Mixing I nstructions

This product mixes readily with water. Mix spray solutions of this product as follows:

1. Fill the mixing or spray tank with the required amount of clean water. If addition of ammonium sulfate is desired to enhance performance of the product, see the a mmonium s ulfate section of the herbicide product label.

2. Add the specified amount of this product near the end of the filling process and mix well. During mixing and application, foaming of the spray solution may occur. To prevent or minimize foaming, use a commercial defoamer or avoid the use of mechanical agitators, and/or terminate by

- pass a nd return lines at the bottom of the tank.

Note : Use approved anti

- back siphoning devices where required by state or local regulations to avoid siphoning back into the carrier source. 

### Adjuvants (except Ammonium Sulfate)

Enlist Duo herbicide contains low drift properties . The use of adjuvants and drift control additives with Enlist Duo herbicide with Colex

- D Technology can have a negative impact on stability and application performance. The a ddition of some adjuvants may also result in increased crop injur y, decreased weed control, and/or increased potential for spray drift. The compatible adjuvants for use with Enlist Duo are

listed below. If an adjuvant is desired for use with Enlist Duo, it must be selected from this list of products. Dow AgroSciences is released of all performance liability if a non

- compatible adjuvant is used.

 List of Adjuvants will be inserted into final Product Use Guide



### Tank M ixing w ith O ther P roducts
Some herbicides, fungicides, micronutrients and insecticide products may require drift management and application equipment set

- ups that differ from Enlist Duo TM herbicide. Additionally, the formulation components of some products may contain inert ingredi ents that negatively affect the low

- drift properties offered with Enlist Duo with Colex

- D Technology. The approved list of tank mix partners is below. Tank mix to the most restrictive label. If th e most restrictive label reduces the agronomic benefit o f an approved tank mix partner to an unacceptable level (i.e. a fungicide being applied in a coarse droplet), these products should not be tank

- mixed with Enlist Duo herbicide.

 L ist of Approved Tank Mix Partners will be inserted into final Product Use Guide



### Restrictions

Refer to the product label for specific planting restrictions, weed height and use information for annual and perennial weeds. During the growing season following application, do not replant fields with crops other than those labeled for use with 2,4

- D and glyphosate.

- tolerant corn: rinse the spray equipment with clean water to at least 10 percent of the total tank volume and spray the solution out of the spray tank through the boom.

If the application immediately following Enlist Duo is to an y other crop, use the triple

- rinse sprayer cleanout procedure for Enlist Duo TM herbicide below:

### DRAFT

— NOT FOR FURTHER DISTRIBUTION

 Completely drain the spray system, including lines and spray boom, for at least five minutes.

 Fill the container with clean water to at least 10 percent of the total tank volume and circulate the solution through the entire system so that all internal surfaces are contacted for at least 15 minutes to complete the first rinse of the application equipment. Spray the solution out of the spray tank through the boom.

 Completely drain the spray system, including lines and spray boom if possible , for at least five minutes; remove and clean filters and strainers.

 Fill the container with clean water to at least 10 percent of the total tank volume. During the

seco nd rinse, tank cleaning agents may be added at the manufacturer’s recommended rates. Circulate the solution through the entire system so that all internal surfaces are contacted for at least 15 to 20 minutes. Let the solution stand for several hours, prefe rably overnight. Spray the solution out of the spray tank through the boom

.

 Completely drain the spray system, including line s, spray boom and dead ends if possible , for at least five minutes. Follow manufacturer directions for addressing dead ends on spr ay booms.

 Fill the container with clean water to at least 10 percent of the total tank volume and circulate the solution through the entire system so that all internal surfaces are contacted for at least 15 minutes to complete the third rinse of the appli cation equipment. Spray the solution out of the spray tank through the boom.

 Completely drain the spray system, remove nozzle tips and strainers and clean them separately.


# Weed Management

Repeated use of herbicides with the same mode of action can lead to selection for resistant biotypes within the larger population of weeds. The key to controlling existing resistant weeds and slowing the development of new resistant weeds is to diversify a nd reduce selection pressure on the weed population while still maintaining high levels of weed control that limit weed seed production.

Diversification of weed management strategies can be accomplished by integrating several proven practices for weed co ntrol, such as:

 Rotate crops and cultural practices to allow for a wider range of weed control practices.

 Start with a clean field, using either a burn

- down herbicide application or tillage and scout fields before and after herbicide application.

 Use the c orrect herbicide product at the right rate and time and apply herbicide mixtures with different modes of action.

 Control weeds early when they are relatively small. Rotate herbicides that have different modes of action and use residual herbicides that have different modes of action.

 Use new commercial, weed

- free crop seed and clean equipment before moving from field to field to minimize spread of weed seed.

 Control weed escapes and prevent weeds from setting seeds. Incorporate other herbicides and cultural practices as part of the herbicide

- tolerant cropping systems where appropriate.
