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 may be applied preplant, at-planting, preemergence, and postemergence (in-crop) for weed control in dicamba-tolerant cotton and dicamba-tolerant soybeans. The use in dicamba-tolerant crops is only allowed in the following states: Alabama, Arizona, Arkansas, Colorado, Delaware, Florida (excluding Palm Beach County), Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Mississippi, Missouri, Nebraska, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, South Carolina, South Dakota, Tennessee (excluding Wilson County), Texas, Virginia, West Virginia, Wisconsin.

Additional state restrictions and requirements may apply. The applicator must comply with any additional state requirements and restrictions.

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. See Tank Mixing Information section for important information on herbicide tank mixes or Crop-specific Information section(s) for recommendations on 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 to minimize the likelihood of weed resistance occurring. DO NOT apply at less than the labeled rate. See Crop-specific Information for labeled rates by crop.

- 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 only EPA-approved nozzles that produce extremely coarse to ultra-coarse spray droplets. See for the list of nozzles approved for use with this product.

- Maintain boom height 24 inches or less from target.

- Identify areas of sensitive nontarget crops/plants and maintain proper setback distance from these areas (see Treatment Zone Awareness and Buffer Requirements (Sensitive Areas, Sensitive Crops and Residential Areas) section for Spray Buffer requirements).

Sensitive crops in agricultural and/or residential settings can include, but are not limited to:
- non-DT soybeans
- cucumber and melons (EPA Crop Group 9)
- flowers
- fruit trees
- grapes
- ornamentals including greenhouse-grown and shade house-grown broadleaf plants
- peanuts
- peas and beans (EPA Crop Group 6)
- peppers, tomatoes, and other fruiting vegetables (EPA Crop Group 8)
- potato
- sweet potato
- tobacco
- Thoroughly clean spray equipment before and 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 sensitive 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 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 labeled rates of Engenia for the most difficult-to-control weed in the field at the specified time (correct weed size) to minimize weed escapes. See Crop-specific Information for labeled rates by crop.

- 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.

- Indicators of possible herbicide resistance include: (1) failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; (2) a spreading patch of non-controlled plants of a particular weed species; (3) surviving plants mixed with controlled individuals of the same species.

- Report any incidence of non-performance of this product against a particular weed species to your BASF retailer, representative or online at

- 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 herbicide 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 and after 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
Apply Engenia by ground 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. 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 Tank Mixing Information 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 when contacting their roots, stems, or foliage.

Application Methods and Equipment
Apply Engenia by ground. Thorough spray coverage is important for best broadleaf weed control and can be improved with 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 herbicide may be applied using water; consult crop specific information sections of this label for other spray carrier options.

Ground Application
Banding Applications
When applying Engenia by banding, use the formula given 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 15 gallons of water or more 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.

Use Precautions

- 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.

- Rainfast Period - Engenia is rainfast 4 hours after application. Postemergence activity may be reduced if rain or irrigation occurs within 4 hours of application.

Use Restrictions

Applicator MUST ALSO follow restrictions under Crop-specific Information section(s).

- DO NOT apply this product aerially.

- DO NOT apply Engenia with ammonium-containing additives, conditioners, or fertilizers (e.g. AMS, UAN). Small quantities of AMS can greatly increase the volatility potential of dicamba.

- DO NOT apply Engenia if expected rainfall amount may exceed soil field capacity and result in soil runoff in the next 24 hours.

- DO NOT apply Engenia if wind speed is less than 3 mph or greater than 10 mph.

- DO NOT apply Engenia at night. DO NOT apply earlier than one hour after sunrise or later than two hours before sunset.

- DO NOT contaminate irrigation ditches or water used for domestic purposes.

- DO NOT apply Engenia through any type of irrigation system (e.g. chemigation).

- DO NOT tank mix Engenia with LorsbanR insecticide.

- In DT cotton, DO NOT apply Engenia later than 60 days after planting or mid-bloom, whichever comes first.

- In DT soybeans, DO NOT apply Engenia later than 45 days after planting or R1, whichever comes first.

Crop Rotation Restrictions
Use the following information to determine the required interval between Engenia herbicide application and rotational crop planting as well as replanting after crop failure because of environmental factors such as drought, frost, or hail. Determine the rotational crop interval for tank mix products and use the most restrictive interval of all products applied.

Limitations, Restrictions, and Exceptions

Pasture, Hay, Rangeland, and Farmstead (noncropland)

Engenia may be used on pasture, hay, rangeland, and farmstead including fencerows and nonirrigation ditchbanks for control or suppression of broadleaf weed and woody brush and vine species listed in Table 1. Engenia uses described in this section also refer to small grain grown for forage pasture use (rye, sorghum, sudangrass, or wheat). Grazing and harvest intervals are shown in Table 5.

Engenia may also be applied to noncropland areas to control broadleaf weeds in noxious weed control programs, districts, or areas including broadcast or spot treatment of roadsides, highways, utilities, railroad, and pipeline rights-of-way. Noxious weeds must be recognized at the state level, but programs may be administered at state, county, or other level.

Application Rates and Timings
Refer to Table 2 for rate selection based on targeted weed or brush species. Some weed species will require a tank mix partner for adequate control. Retreatments may be applied as needed.

For approved tank mix options see

DO NOT apply more than 25.6 fl ozs/A of Engenia during a growing season.

DO NOT apply more than 12.8 fl ozs/A of Engenia during a growing season on small grain grown for pasture and newly seeded areas.

Established grass crops growing under stress can exhibit various injury symptoms that may be more pronounced if herbicides are applied. Bentgrass, buffalograss, carpetgrass, and St. Augustinegrass may show a response.

Usually, colonial bentgrasses are more tolerant than creeping types. Velvetgrasses are most easily injured. Treatments will injure or kill alfalfa, clovers, lespedeza, wild winter peas, vetch, and other legumes.

Spray volume may range from 10 to 600 gallons per acre. The volume of spray applied depends on the height, density, and type of weeds or brush being treated and on the type of equipment used. Engenia may be applied as a spot treatment to individual clumps or small areas of undesirable vegetation using a handgun or similar type of application equipment. Apply diluted sprays to allow complete wetting (up to runoff) of foliage and stems.

Pasture, Hay, Rangeland, and Farmstead (noncropland) Restrictions

- DO NOT apply more than a maximum cumulative total of 25.6 fl ozs/A of Engenia (1 lb dicamba ae/A) during a growing season.

- DO NOT apply more than a maximum cumulative total of 12.8 fl ozs/A of Engenia (0.5 lb dicamba ae/A) to small grain grown for pasture and to newly seeded areas.
