2024 Dicamba Update - Vacated Labels / Existing Stocks Policy
February 14, 2024, USEPA issued an Existing Stocks Policy allowing use of the over-the-top dicamba formulations on soybeans and cotton in 2024. The products affected are XtendiMax by Bayer, Engenia by BASF and Tavium by Syngenta. EPA’s order allows use of the herbicide already distributed from these registrants. Use of these products must follow the restrictions on the label and any state specific restrictions that are in place. Registrants are not allowed to distribute any products that weren’t already in the channels of trade by the February 6th court decision. Retail ag center, co-ops, etc. who had products on hand by February 6th are allowed to sell and distribute the products according to state specific deadlines. Use of the product is allowed until the cutoff date of June 12th or V4 growth stage in soybeans.
In Illinois, No distribution or sale of these products is allowed after May 13, 2024.
No application may occur after June 12, 2024 or V4 growth stage in soybeans.
All Illinois specific application restrictions must still be followed:
DO Not Apply if the air temperature at the field at the time of application is over 85 degrees Fahrenheit or if the National Weather Service forecasted high temperature for the nearest available location for the day of application exceeds 85 degrees Fahrenheit. (Local National Weather Service forecast available at https://www.weather.gov)
DO NOT apply when the wind is blowing toward adjacent residential areas.
DO NOT apply when the wind is blowing toward any adjacent Illinois Nature Preserves Commission Site.
Must consult FieldWatch sensitive crop registry before application.
DO NOT apply after June 12th. (The federal cutoff date of June 12th supersedes the State specific restriction of June 20th )
February 6, 2024, The U.S. District Court for the District of Arizona in Tucson vacated the 2020 USEPA approved registrations for the three over the top (OTT) dicamba products labeled for use on soybeans and cotton. The products affected are XtendiMax by Bayer, Engenia by BASF and Tavium by Syngenta. Pending EPA action, no distribution, sale or use of these products is allowed.
2023 Dicamba Update - June 12th Cutoff Date
February 16, 2023, USEPA approved labeling amendments that further restrict the use of over-the-top dicamba in Iowa, Illinois, Indiana, and South Dakota. The amendments were made at the request of the registrants and affect the following products: Bayer-Xtendimax, BASF-Engenia, and Syngenta-Tavium.
The revised labeling prohibits the use of over-the-top dicamba application on dicamba tolerant crops after June 12th or V4 in soybeans in Illinois, Iowa, and Indiana and after June 20th in South Dakota.
The JUNE 12th cutoff date supersedes the Illinois specific cutoff date of June 20th .
ALL other Illinois Specific Requirements remain in place.
- A pesticide containing dicamba shall not be applied on soybeans if the air temperature at the field at the time of application is over 85 degrees Fahrenheit or if the National Weather Service's forecasted high temperature for the nearest available location for the day of application exceeds 85 degrees Fahrenheit. Local National Weather Service forecasts are available at https://www.weather.gov.
- Before applying a pesticide containing dicamba on soybeans, the applicator shall consult the FieldWatch sensitive crop registry (https://www.fieldwatch.com ) and comply with all associated recordkeeping and label requirements.
- Application on soybeans of a pesticide containing dicamba shall not be made if the wind is blowing toward: any Illinois Nature Preserves Commission site that is adjacent to the field of application; or an adjacent residential area.
State-Specific Restrictions for Dicamba on Soybeans in 2022
Friday, December 17, 2021
SPRINGFIELD, IL - The Illinois Department of Agriculture's (IDOA) proposed administrative rules for the use of Dicamba on soybeans were published in the Secretary of State's Illinois Register today. The proposed restrictions for dicamba use on soybeans are the same restrictions that were required in 2021. The publication of the rules in the Illinois Register begins the First Notice period, during which IDOA must accept comments from the public.
In October 2020, USEPA announced that it had renewed the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) registrations for three dicamba pesticides for growing seasons 2021-2025. Contrary to prior practice, USEPA declared that the only way for states to add safety restrictions to these products is through Section 24(a) of FIFRA, which allows a state to add restrictions through its rulemaking process.
In February 2021, IDOA filed emergency rules detailing additional restrictions for dicamba application on soybeans for the 2021 growing season. Since the Illinois Administrative Procedure Act prohibits state agencies from adopting emergency rules more than once in any 24-month period, the Department is now required to proceed with the permanent rulemaking process.
In addition to the requirements of the federally-approved labels, IDOA's proposed rules include the following requirements for the use of pesticides containing dicamba on soybeans:
- A pesticide containing dicamba shall not be applied on soybeans if the air temperature at the field at the time of application is over 85 degrees Fahrenheit or if the National Weather Service's forecasted high temperature for the nearest available location for the day of application exceeds 85 degrees Fahrenheit. Local National Weather Service forecasts are available at
https://www.weather.gov
. - Application on soybeans of a pesticide containing dicamba shall not be made after June 20 of each year.
- Before applying a pesticide containing dicamba on soybeans, the applicator shall consult the FieldWatch sensitive crop registry (
https://www.fieldwatch.com
) and comply with all associated recordkeeping and label requirements. - Application on soybeans of a pesticide containing dicamba shall not be made if the wind is blowing toward: any Illinois Nature Preserves Commission site that is adjacent to the field of application; or an adjacent residential area.
"The number of off-target complaints received over the past two growing seasons has declined dramatically since implementing changes to label restrictions," said Jerry Costello II, Director, IDOA. "The decision to keep these rules in place was made after evaluating several factors, including the reduction of pesticide misuse cases involving the use of dicamba on soybeans from 2019 to 2020."
In addition to these provisions, applicators must follow the federal guidelines when it comes to applying dicamba, including taking annual Dicamba specific training and be a certified applicator.
The intent of these additional restrictions is to reduce the potential for off-target movement of this product, thereby reducing the potential for possible adverse impacts to dicamba-sensitive crops/areas. Dicamba is primarily used on soybeans to control post-emergence broadleaf weeds.

State-Specific Restrictions for Dicamba on Soybeans in 2021
The Illinois Department of Agriculture (IDOA) released emergency administrative rules detailing additional restrictions for dicamba application on soybeans for the 2021 growing season.
In October 2020, USEPA announced that it had renewed the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) registrations for three dicamba pesticides for growing seasons 2021-2025. Contrary to prior practice, USEPA declared that the only way for states to add safety restrictions to these products is through Section 24(a) of FIFRA, which allows a state to add restrictions through its rulemaking process.
IDOA filed emergency rules effective February 5, 2021. Impacted registrations include: XtendiMax with VaporGrip Technology, Engenia Herbicide and Tavium Plus VaporGrip Technology.
In addition to the requirements of the federally-approved labels, all use of pesticides containing dicamba on soybeans in Illinois must comply with the following requirements:
- TEMPERATURE RESTRICTION
A pesticide containing dicamba
shall notbe applied on soybeans if the air temperature at the field at the time of application is over 85 degrees Fahrenheit or if the National Weather Service's forecasted high temperature for the nearest available location for the day of application exceeds 85 degrees Fahrenheit. Local National Weather Service forecasts are available at https://www.weather.gov.
- CUT-OFF DATE RESTRICTION
Application on soybeans of a pesticide containing dicamba
shall not be made after June 20 of each year. Before applying a pesticide containing dicamba on soybeans, the applicator shall consult the FieldWatch sensitive crop registry (
https://www.fieldwatch.com
) and comply with all associated recordkeeping and label requirements.- Application on soybeans of a pesticide containing dicamba shall not be made if the wind is blowing toward:
- any Illinois Nature Preserves Commission site that is adjacent to the field of application; or
an adjacent residential area.
"After the announcement of the USEPA decision and as the lead agency of pesticide regulation in the State of Illinois, the Department quickly looked at options to allow farmers to make their input decisions for the 2021 growing season in a timely manner," said Acting Director Jerry Costello II. "Illinois is the number one soybean producing state in the nation, and it's critical to balance the use of this important tool (dicamba) while also protecting surrounding farmers, landowners, specialty crops, trees, forests, and natural areas.
In 2019, IDOA received 723 dicamba-related complaints. Subsequently, IDOA initiated a June 20 application cut-off date and 85-degree temperature restriction, which led in part to an 80% (147) decrease in dicamba-related complaints in 2020.
Dicamba Labels
On October 27, 2020, EPA announced the registration of two end-use dicamba products (Engenia (BASF) and Xtendiamax with VaporGrip Technology (Bayer)) and extended the registration for one dicamba product (Tavium with VaporGrip Technology (Syngenta)), all for applications only on dicamba-tolerant cotton and dicamba-tolerant soybeans (EPA Registration Numbers 100-1623, 264-1210, and 7969-472). These product registrations are valid until December 2025 unless EPA takes further action to amend the registrations.

Currently 18 Illinois counties instead of 29 as required in the 2018 dicamba labels.
Prior to making any applications of one of the three approved dicamba products, applicators must visit
www.epa.gov/espp
to check for additional restrictions.
Endangered Species Protection Bulletins are a part of EPA's Endangered Species Protection Program. Bulletins set forth geographically specific pesticide use limitations for the protection of threatened and endangered (listed) species and their designated critical habitat.
If your pesticide label directs you to the Bulletin Web site, you are required to follow the pesticide use limitation(s) found in the Bulletin for your intended application area, pesticide active ingredient or product and application month.
Bulletins may be accessed up to six months before pesticide application. Be sure that you follow the correct Bulletin for the month of your pesticide application.
The following areas may be included in the buffer distance calculation when directly adjacent to the treated field edges:
- Roads, paved or gravel surfaces, mowed grassy areas adjacent to field, and bare ground from recent plowing or grading that are contiguous with the treated field.
- Planted agricultural fields containing dicamba-resistant plantings of cotton and soybeans.
- Areas covered by the footprint of a building, silo, or other manmade structure with walls and/or roof.
Planted agricultural fields containing corn or crops other than dicamba-resistant plantings of cotton or soybeans are not allowed to be used in the endangered species buffer distance calculations.
