ADDITIONAL APPLICATION RESTRICTIONS FOR USE ON DICAMBA-TOLERANT SOYBEAN AND DICAMBA-TOLERANT COTTON - MISSOURI

General Information

Product Information

Engenia herbicide is a water-soluble herbicide that provides postemergence and moderate rate-dependent residual control of many annual broadleaf weeds. Engenia is also active on many biennial and perennial broadleaf weeds as well as woody brush and vines (refer to Table 1 for weeds controlled or suppressed).
Engenia can be used in specific field and row crops, fallow and postharvest croplands, and sod farms. Engenia does not control grass weeds and must be used sequentially or tank mixed with a grass herbicide for a complete weed control program. Refer to Crop-specific Information section for recommendations on herbicide tank mixes or sequential programs.

Product Stewardship Practices

- Apply Engenia herbicide to weeds 4 inches or less in size for best performance.
- Apply Engenia at the labeled rate.
- Use Engenia as part of a herbicide program that includes the use of residual herbicides and herbicides with alternate sites of action to reduce resistance selection pressure.
- Select nozzles that produce extremely coarse to ultra-coarse spray droplets.
- Maintain boom height 24 inches or less from target.
- Identify areas of sensitive nontarget plants and maintain proper setback distance from these areas.
- Thoroughly clean spray equipment after application.

Mode of Action

Dicamba, the active ingredient in Engenia, is a Group 4 (WSSA) herbicide. Herbicides in this group mimic auxin (a plant hormone) resulting in a hormone imbalance in susceptible plants that interferes with normal plant growth (e.g. cell division, cell enlargement, and protein synthesis).
Engenia is readily absorbed by leaves, roots, and shoots; translocates throughout the plant; and accumulates in areas of active growth to provide postemergence control of emerged weeds as well as moderate residual control of germinating weed seeds.
Any weed population may contain plants naturally resistant to Group 4 herbicides. Weeds resistant to Group 4 herbicides may be effectively managed using herbicide(s) from a different group and/or by using cultural or mechanical practices. Report any incidence of non-performance of this product against a particular weed species at www.Non-Performance.BASF.US. Consult your local BASF representative, state cooperative extension service, professional consultants, or other qualified authority to determine appropriate actions if you suspect resistant weeds.
Additional information about weeds which are known to be resistant to dicamba can be found at www.Resistance-Information.BASF.US.

Resistance Management

While weed resistance to Group 4 herbicides is infrequent, populations of resistant biotypes are known to exist.
Resistance management should be part of a diversified weed control strategy that integrates multiple options including chemical, cultural, and mechanical (tillage) control tactics. Cultural control tactics include crop rotation, proper fertilizer placement, optimum seeding rate/row spacing, and timely tillage.

To aid in the prevention of developing weeds resistant to this product, the following steps should be followed where practical:
- Start clean with tillage or an effective burndown herbicide program.
- DO NOT rely on a single herbicide site of action for weed control during the growing season.
- Scout fields before application to ensure herbicides and rates will be appropriate for the weed species and weed sizes present.
- Apply full rates of Engenia herbicide for the most difficult-to-control weed in the field at the specified time (correct weed size) to minimize weed escapes.
- Use of preemergence herbicides that provide soil residual control of broadleaf and grass weeds is recommended to reduce early season weed competition and allow for more timely in-crop postemergence herbicide applications.
- Avoid application of herbicides with the same site of action more than twice a season.
- Scout fields after application to detect weed escapes or shifts in weed species.
- Report any incidence of non-performance of this product against a particular weed species to your BASF retailer, representative or online at www.Non-Performance.BASF.US.
- If resistance is suspected, treat weed escapes with a herbicide having a mode of action other than Group 4 and/or use non-chemical methods to remove escapes, as is practical, with the goal of preventing further seed production.
- For more information about weeds that are known to be resistant to dicamba go to www.Resistance-Information.BASF.US.
Additionally, users should follow as many of the following herbicide resistance management practices as is practical:
- Use a broad spectrum soil-applied herbicide with other modes of action as a foundation in a weed control program.
- Utilize sequential applications of herbicides with alternative modes of action.
- Rotate the use of this product with non-Group 4 herbicides.
- Avoid making more than two applications of Engenia and any other Group 4 herbicides within a single growing season unless mixed with another mechanism of action with an overlapping spectrum for the difficult-to-control weeds.
- Incorporate non-chemical weed control practices, such as mechanical cultivation, crop rotation, cover crops and weed-free crop seeds, as part of an integrated weed control program.
- Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds.
- Manage weeds in and around fields during and after harvest to reduce weed seed production.
- Contact the local agricultural extension service, BASF representative, ag retailer or crop consultant for further guidance on weed control practices as needed.

Crop Tolerance

Crops growing under normal environmental conditions are tolerant to Engenia when applied according to label directions.
Crop injury may occur under stressful growing conditions (e.g. low soil fertility, seedling disease, extreme hot or cold weather, excessive moisture, high soil pH, high soil salt concentration, drought).

Application Instructions

Engenia can be applied to actively growing weeds as a band, broadcast, or spot spray application for postemergence control of emerged weeds as well as moderate residual control of germinating weed seeds. Apply Engenia by air or ground depending on crop-specific use.

Make postemergence applications of Engenia when broadleaf weeds are small and actively growing. An adjuvant is recommended with Engenia for best postemergence activity; refer to Adjuvants section and crop-specific information sections for details.

Postemergence activity may be slowed or reduced under cloudy and/or foggy or cooler weather conditions, or when weeds are growing under drought or other stress conditions.

When targeting dense weed populations and/or larger broadleaf weeds, use higher spray volumes and a higher application rate within an application rate range.
Cultivation should be delayed until 7 days after applying Engenia or a reduction in weed control may occur.

Use extreme care when applying Engenia to prevent injury to desirable plants. Engenia may cause injury to desirable sensitive plants (particularly beans, cotton, fruit trees, grapes, ornamentals, peas, potato, soybean, sunflower, tobacco, tomato, and other broadleaf plants) when contacting their roots, stems, or foliage. These plants are most sensitive to Engenia during periods of rapid vegetative growth or flowering. Refer to Application Methods and Equipment section.

Application Rates

Always read and follow crop-specific use directions.

Application Methods and Equipment

Engenia may be applied by air and/or ground depending on use. Thorough spray coverage is important for best broadleaf weed control and can be improved with proper adjuvant, nozzle, and spray volume selection. Calibrate application equipment for accurate target spray volume and application rate to ensure uniform distribution of spray and to avoid spray drift to nontarget areas. Adjust equipment to maintain continuous agitation during spraying with good mechanical or bypass agitation. Avoid overlaps that will increase rates above the labeled use rates. Engenia may be applied using water; consult crop-specific information sections of this label for other spray carrier options.

Aerial Application

Use 1 to 10 gallons of water per acre (2 to 20 gallons diluted spray per treated acre for preharvest uses). Use the higher spray volume when treating dense or tall vegetation. DO NOT apply when conditions favor drift from target area.

Ground Application

Banding Applications
When applying Engenia by banding, use the formula in the label to calculate the amount of herbicide and water volume needed.

Broadcast Applications
Unless noted in the crop-specific information section, use a spray volume of 5 or more gallons of water per treated acre. Thorough coverage of existing vegetation is essential for postemergence applications; higher spray volumes may be necessary for optimum performance.

Wiper Applications
Engenia may be applied through wiper application equipment to control or suppress actively growing broadleaf weeds, brush, and vines. Use a 50% solution containing 1 part Engenia to 1 part water.

- DO NOT apply more than 12.8 fl ozs/A of Engenia [0.5 lb dicamba acid equivalent (ae) per acre] per application.
- DO NOT contact desirable vegetation with herbicide solution. Wiper application may be made to crops (including pastures) and noncropland areas described in this label.

EXCEPTION: DO NOT use wiper application on non-dicamba-tolerant cotton or soybean.

Adjuvants
See crop-specific information sections for specific application requirements. To improve postemergence weed control with Engenia, a Chemical Producers and Distributors Association (CPDA) certified adjuvant may be used. Some adjuvants have the potential to cause crop injury under certain conditions, at certain growth stages, and/or under other circumstances. Read all labels for products used in the tank mixture before use to determine the potential for crop injury.
BASF recommends the use of quality adjuvants with Engenia such as AstonishTM, Class Act Ridion, Grounded, Iconic, JackhammerTM Elite, R-11, Strike Force, and Verifact.

Surfactants and Spreaders Nonionic Surfactants/Spreaders (NIS)
Use an agriculturally approved nonionic surfactant (containing at least 80% active ingredient) at 1 to 2 pints/100 gallons [0.12 to 0.25% volume/volume (v/v)].
Use the highest rate of NIS when using the lower rate ranges of a tank mix or when treating more mature and difficult-to-control weeds or dense vegetative growth.

OR

Oil Concentrate Surfactants (COC, HSOC, MSO)*
When specifically allowed in crop specific information sections of this label, oil concentrate may be used at 2 to 4 quarts/100 gallons (0.5% to 1.0% v/v), but at least 1 pint/A.
Crop oil concentrate must contain either a petroleum-oil or vegetable-oil base and must:
- Be nonphytotoxic
- Contain only EPA-exempt ingredients
- Provide good mixing quality in the jar test
- Be successful in local experience
Petroleum-oil and vegetable-oil concentrates should contain emulsifiers to provide good mixing quality. Highly refined vegetable oils have proven more satisfactory than unrefined vegetable oils.
* COC - crop oil concentrate
HSOC - high surfactant oil concentrate
MSO - methylated seed oil

Water Conditioners and Nitrogen Additives
Hard water does not usually affect the activity of Engenia; however, other tank mix components may be adversely affected (e.g. glyphosate). Use of a conditioning agent should be considered when hard water (i.e. total calcium, magnesium, and iron content above 500 ppm) is used as a spray carrier. A neutral buffering agent may be warranted if the water source or tank mix components will create an acidic spray solution less than pH 5.

Deposition Aids

Consider using a CPDA-approved deposition aid when spraying Engenia herbicide to further reduce fine droplets. Not all deposition aids are compatible with every nozzle type and pesticide/adjuvant combination. Check with the additive manufacturer to ensure the deposition aid will work properly with the spray nozzle, spray pressure, and your specific spray solution. Use of a deposition aid does not replace the need for proper nozzle selection (see Ground Application Spray Drift Management section).

Use Precautions

- Rainfast Period - Engenia is rainfast 4 hours after application. Postemergence activity may be reduced if rain or irrigation occurs within 4 hours of application.
- Maximum Seasonal Use Rate - Refer to crop-specific information sections for maximum seasonal application rates for each crop or use pattern.
- Stress - Application to crops under stress because of lack of moisture, hail damage, flooding, herbicide injury, mechanical injury, or widely fluctuating temperatures may result in crop injury.

Use Restrictions

- DO NOT contaminate irrigation ditches or water used for domestic purposes.
- DO NOT apply Engenia through any type of irrigation system (e.g. chemigation).
- Engenia is compatible with most pesticides; however, DO NOT tank mix Engenia with Lorsban insecticide.

Crop-specific Information

This section provides use directions for Engenia in specific crops; read product information, application instructions, weeds controlled, and additive instructions in preceding sections of the label. Read and follow tank mix product labels for restrictions, precautions, instructions, and crop rotation restrictions.
Depending on specific crop application directions, Engenia may be applied for postemergence control of emerged broadleaf weeds and/or residual control of germinating broadleaf weed seeds before crop planting (preplant and/or preseed) and after planting (preemergence, postemergence). Refer to Table 1 for list of weeds controlled or suppressed.
