Were You (or a Loved One) Diagnosed with Non-Hodgkin’s Lymphoma or Parkinson’s Disease After Working With or Being Exposed to Atrazine Herbicide Products?
Atrazine Herbicide Injury Lawsuits & Settlements
Reviewed by Jacobs Kolton, Chtd. Attorneys at Law; Updated July 2026
Atrazine lawsuits involve claims by farmworkers, herbicide applicators, agricultural employees and others that exposure to atrazine-containing herbicide products (e.g., AAtrex, Atrazine 4L/90DF, Bicep, Lexar, Lumax, Acuron, Callisto Xtra, Harness Xtra, Degree Xtra, Keystone, FulTime, Guardsman Max, ATZ, etc.) caused or contributed to their developing non-Hodgkin’s lymphoma and/or Parkinson’s disease.
Our team of products liability injury lawyers and class action attorneys is investigating potential atrazine lawsuit cases and settlement claims involving individuals who were diagnosed with non-Hodgkin lymphoma or Parkinson’s disease after being exposed to atrazine herbicide products.
If you (or a loved one) were diagnosed with non-Hodgkin’s lymphoma or Parkinson’s disease after being exposed to atrazine herbicide products, you may be entitled to recover compensation from an atrazine lawsuit case or settlement claim.
Atrazine is a widely used herbicide primarily applied in agriculture to control broadleaf and grassy weeds in crops like corn, sorghum, and sugarcane. It eliminates weeds by interfering with photosynthesis in susceptible plants while leaving tolerant crops unharmed.
Unfortunately, atrazine can be toxic to humans, particularly when someone swallows it, inhales spray or dust, or has substantial or repeated skin exposure. Indeed, according to various research studies, atrazine exposure may be associated with an increased risk of developing neurological disorders such as Parkinson’s disease and cancers such as non-Hodgkin’s lymphoma.
Parkinson’s disease is a progressive disorder of the nervous system that can interfere with movement, balance, coordination, and other bodily functions that depend on dopamine (i.e., a chemical messenger that helps the brain regulate smooth, controlled movement and other functions). Parkinson’s develops when certain dopamine-producing nerve cells in the brain gradually become damaged or die.
Non-Hodgkin lymphoma is a type of cancer that begins in the lymphatic system (part of the body’s immune system). It develops when white blood cells (lymphocytes), grow and multiply abnormally. These cancerous cells may accumulate in lymph nodes, spleen, bone marrow, blood, or other organs and interfere with the body’s ability to fight infection.
Parkinson’s disease and non-Hodgkin’s lymphoma victims (and families of loved ones who died from either disease) are now coming forward and filing atrazine lawsuits seeking compensation and justice for the harm and suffering they may have endured after being exposed to atrazine.

- Parkinson’s disease
- Parkonsonism
- Non-Hodgkin’s lymphoma
- Follicular lymphoma
- Diffuse large B-cell lymphoma (DLBCL)
If you (or a loved one) were diagnosed with Parkinson disease or non-Hodgkin’s lymphoma after exposure to atrazine, you may be eligible to recover compensation from an atrazine lawsuit case or settlement claim.
Who May Qualify for an Atrazine Parkinson’s Disease or Non-Hodgkin’s Lymphoma Lawsuit Case
Individuals may qualify for an atrazine Parkinson’s or non-Hodgkin’s lymphoma lawsuit case or settlement claim if they (or a loved one):
- Were Exposed to Atrazine: Used or were exposed to atrazine-containing herbicide product(s) over a long period of time.
- Suffered Injury or Death From Parkinson’s Disease or Non-Hodgkins Lymphoma: Suffered injury, complications and/or death from Parkinson’s disease or non-Hodgkin’s lymphoma cancer after exposure to atrazine herbicide products.
Other criteria may apply in order to be eligible. Not all individuals or cases qualify for an atrazine lawsuit. Individuals may not qualify if: (1) medical factors or other factors make it difficult to link the injuries to atrazine; (2) the duration of exposure to atrazine was too short; (4) the amount of time between exposure to atrazine and diagnosis with Parkinson’s disease or non-Hodgkin’s lymphoma was not long enough (i.e., not at least 2 years after exposure); (5) the amount of time between exposure to atrazine and diagnosis with Parkinson’s disease or non-Hodgkin’s lymphoma was too long (i.e., more than 15 years after exposure); (6) diagnosed with non-Hodgkin’s lymphoma at age 70 or older or diagnosed with Parkinson’s disease at age 75 or older; (7) the claim is outside the statute of limitations or statute of repose period (if an individual waits too long they may be legally barred from suing); and/or (8) medical records do not support the atrazine injury claims. Individuals may not qualify for other reasons.
Atrazine Lawsuit: Summary of Key Information
| Key Information | What It Means |
|---|---|
| Atrazine | Atrazine is a selective systemic herbicide in the triazine chemical family that is used to control broadleaf weeds and annual grasses. Atrazine works by interfering with photosynthesis in susceptible plants. |
| Herbicide | An herbicide is a type of pesticide designed to kill, suppress, or prevent the growth of unwanted plants, commonly called weeds. Herbicides may be selective, meaning they target certain plants while leaving crops or grasses relatively unharmed, or nonselective, meaning they can injure or kill most vegetation they contact. They may be applied before weeds emerge, after weeds begin growing, or directly to the soil, depending on the product and intended use. |
| Common Uses of Atrazine | In the U.S. atrazine is applied primarily to corn, sorghum, and sugarcane, and it may be used before planting, before weeds emerge, or after early weed growth begins. Atrazine has also been registered for certain non-agricultural uses, including some turf, nursery, and ornamental applications. |
| Atrazine Products | Atrazine products have included AAtrex, Acuron, Bicep, Cinch, Expert, Lexar, Lumax, Cadence FulTime, Harness, Keystone, Drexel atrazine, Loveland atrazine, Helena atrazine, Degree Xtra and many other atrazine-containing herbicides. |
| Who May Have Been Exposed to Atrazine Herbicides | Farmworkers, pesticide applicators, agricultural workers, nursery/greenhouse workers, landscapers and atrazine factory workers may have been exposed to atrazine. |
| Atrazine Parkinson’s & Non-Hodgkin’s Lymphoma Lawsuit | A legal action brought by injured individuals or certain surviving family members or heirs of a deceased individual (plaintiffs) to recover money damages against the companies sued (defendants) alleging that exposure to atrazine herbicide products caused or contributed to the injured person suffering from Parkinson’s disease or non-Hodgkin’s lymphoma. |
| Parkinson’s Disease | Parkinson’s disease is a progressive neurological disorder that primarily affects body movement and motor control. It occurs when nerve cells in a specific region of the brain, called the substantia nigra, become damaged or die, leading to a severe drop in the production of dopamine (a vital chemical messenger responsible for coordinating smooth, purposeful muscle movements). As dopamine levels decrease, individuals typically experience classic symptoms such as tremors (shaking, often starting in one hand), muscle stiffness, slowed movement (bradykinesia), and balance or posture difficulties. |
| Non-Hodgkin’s Lymphoma | Non-Hodgkin’s Lymphoma (NHL) is a type of cancer that begins in the lymphatic system, which is a key part of the body’s immune defense against disease. It occurs when a type of white blood cell, called a lymphocyte, undergoes a genetic mutation that causes it to multiply abnormally and collect in the lymph nodes or other organs. |
| Potential Defendants | Possible defendants may include Syngenta Crop Protection, LLC, Syngenta Corporation, Syngenta AG, Corteva Agriscience, Bayer CropScience, Drexel Chemical Company, ADAMA Agricultural Solutions and others. |
| Helpful Evidence | Helpful evidence may include medical records confirming Parkinson’s disease or non-Hodgkin’s lymphoma, records showing exposure to atrazine, pesticide application records, employment records, farm or crop records, purchase receipts, photographs of pesticide containers, witness statements, and expert opinions explaining how atrazine exposure may have contributed to the disease. |
| Possible Compensation | Plaintiffs may seek to recover compensation for medical expenses, lost wages, reduced earning capacity, pain and suffering, loss of enjoyment of life, disability, emotional distress, and other damages. In cases where non-Hodgkin’s lymphoma or Parkinson’s contributed to a person’s death, surviving family may be able to pursue wrongful death damages. |
| Current Status of Litigation | Atrazine lawsuits are in the early stages. Attorneys are reviewing potential atrazine lawsuit cases involving victims who developed Parkinson’s disease or non-Hodgkin’s lymphoma after long-term exposure to atrazine. No centralized atrazine MDL proceeding has been announced yet. No global atrazine settlement has been announced. |
Atrazine Injury Lawsuit Complaints
Farmers, agricultural workers, pesticide applicators, herbicide sprayers, gardeners, landscapers, greenhouse workers, nursery workers and/or other individuals who were exposed to atrazine herbicides and then later developed Parkinson’s disease or non-Hodgkin’s lymphoma (and family of loved ones, in cases involving those who may have died from either disease) are filing atrazine lawsuits seeking to recover monetary compensation.
Atrazine lawsuit complaints may allege, among other things, that defendants designed, manufactured, promoted, distributed, and sold atrazine in a defective and unreasonably dangerous condition; failed to conduct adequate safety testing; misrepresented or minimized its health and environmental risks; contaminated soil and water supplies; and caused personal injury or death from Parkinson’s disease or non-Hodgkin’s lymphoma.
The atrazine lawsuit cases may assert legal claims or causes of action for, among other things, design defect, negligence, strict product liability, breach of warranty, misrepresentation, fraud, and/or violation of consumer protection statutes.
The atrazine lawsuit cases may seek recovery of money damages to compensate for pain and suffering, mental anguish or emotional distress, loss of wages or income due to missed work, loss of future earning capacity, medical care expenses incurred, future cost of medical treatment, other out of pocket expenses, loss of quality or enjoyment of life, disability, loss of consortium and/or wrongful death damages (in cases where a victim died from Parkinson’s disease or non-Hodgkins lymphoma).
Who May Be Sued For Atrazine Injuries
Companies who potentially may be named as defendants in atrazine lawsuit cases may include those that manufactured, formulated, marketed, distributed, sold, supplied, or applied atrazine-containing herbicide products, including for example:
- Syngenta Crop Protection, LLC
- Syngenta Corporation
- Syngenta AG
- Corteva Agriscience (formerly Dow AgroSciences)
- Bayer CropScience (formerly Monsanto)
- Drexel Chemical Company
- ADAMA Agricultural Solutions
- Other potential atrazine defendants
An atrazine lawsuit may name more than one defendant because several companies or entities may have played a role in the injured party’s exposure to atrazine. An atrazine injury lawyer may investigate additional companies depending on the facts of the case, including, among other things, the product label, EPA registration number, purchase records, herbicide application logs, employment records, and herbicide-use records.

Atrazine Lawsuit & Settlement Updates
Recent updates about atrazine lawsuits and settlements include:
- July 2026: Attorneys are currently investigating potential atrazine claims on behalf of individuals who allege that exposure to the herbicide caused non-Hodgkin lymphoma or Parkinson’s disease. At this time, no global atrazine settlement has been announced. At this time, the atrazine litigation has not been centralized in a federal multidistrict litigation proceeding.
Who May Have Been Exposed To Atrazine
Individuals who may have been exposed to atrazine include those who sprayed or used atrazine herbicide products or came into contact with atrazine over a long period of time, including:
- Farmers
- Farm workers
- Agricultural workers
- Crop field workers
- Farm laborers and migrant workers
- Farm owners
- Herbicide applicators
- Herbicide sprayers
- Knapsack or backpack sprayer
- Handheld sprayer
- Motorized sprayer
- Pesticide mixers and loaders
- Tractor or truck driver
- Pilots and aerial-application workers
- Agriculture inspectors
- Field scout or crop consultant
- Agriculture graders and sorters
- Agriculture equipment operators
- Nursery employees
- Garden center employees
- Greenhouse workers
- Horticulture workers
- Landscapers
- Professional gardeners
- Groundskeepers
- Ground maintenance workers
- Atrazine factory workers
- Others exposed to atrazine herbicide
Workers who may be exposed to atrazine include farmers, pesticide applicators, mixers and loaders, aerial-application crews, agricultural fieldworkers, landscapers, groundskeepers, nursery workers, manufacturing and packaging employees, and workers who clean or repair pesticide equipment.
Exposure can occur while mixing, loading, spraying, transporting, or applying atrazine, as well as by entering recently treated fields or handling contaminated crops, soil, tools, machinery, clothing, or protective equipment. These workers may absorb atrazine through their skin, breathe in spray mist, drift, dust, or vapors, or accidentally swallow residues transferred from contaminated hands, food, or drinking water.
How Atrazine Exposure Occurs
Atrazine can enter the body through the skin, lungs, or mouth.
- Skin: Dermal exposure may occur while handling concentrated atrazine, mixing or loading it, or touching treated crops, contaminated soil, equipment, clothing, boots, gloves, or vehicle interiors.
- Lungs: Inhalation exposure can happen by breathing in spray mist, herbicide drift, vapors, contaminated dust, or particles from fields treated with atrazine herbicides.
- Mouth: Oral exposure may occur by swallowing contaminated food, water, or dust, or by transferring atrazine residue from unwashed hands or other contaminated surfaces to the mouth.
Agricultural Crops Atrazine Has Been Used On
Most atrazine use in the U.S. is agricultural, though there is some non-agricultural uses, including turfgrass and nursery/ornamental areas.
The United States Geological Survey (USGS) has estimated that billions of pounds of atrazine were used agriculturally across the United States since at least 1992 on corn and other crops.
Atrazine has most commonly been used on the following crops:
- Field corn
- Sorghum
- Sugarcane
- Sweet corn
- Other crops
According to EPA’s 2020 Atrazine Interim Registration Review Decision, about 72 million pounds of atrazine are used annually in U.S. agriculture. Approximately 98.3% of agricultural atrazine is used on field corn (86.5%), sorghum (8.9%) and sugarcane (2.9%), with field corn accounting for, by far, the largest share. In fact, the EPA’s 2024 update states that more than half of U.S. field-corn, sweet-corn, sorghum and sugarcane acres are treated with atrazine annually.
Locations Where Atrazine Has Been Used
Atrazine use in the United States has been concentrated primarily in agricultural regions where corn is widely grown. The largest area of use is the Midwest and Corn Belt, extending through states such as Iowa, Illinois, Indiana, Nebraska and Ohio and into surrounding parts of the central U.S. USGS monitoring has found some of the highest atrazine concentrations in agricultural streams within major corn-growing areas of these states, reflecting the herbicide’s regional pattern of application.
Atrazine has also been used in the Great Plains, particularly in areas where corn and sorghum are produced. USGS assessments identify the western Corn Belt and eastern Great Plains as regions with relatively high agricultural atrazine use. Farther south, atrazine is applied to sugarcane in the Gulf Coast and southern farming regions. EPA’s regulatory assessments specifically address sugarcane applications in Louisiana, Texas and Florida, with different proposed maximum application rates reflecting differences in regional soil and production conditions.
Although most atrazine is used in agriculture, its use has not been limited entirely to crop fields. EPA registrations have also included uses on turf, sod, nursery plants and ornamentals. Turf applications have historically been associated particularly with the Southeastern United States, including Florida, where atrazine can be used on certain warm-season grasses. Smaller agricultural uses have also been registered for crops such as wheat, guava and macadamia nuts.
Overall, atrazine use has been most heavily concentrated across the central and eastern United States, following the geographic distribution of corn, sorghum and sugarcane production. The exact locations and permitted uses can change because individual product labels and state or local restrictions may impose additional requirements
Types of Atrazine Formulations
Atrazine has been sold in several formulations. The active ingredient is the same, but its concentration, carrier ingredients and physical form can differ. Formulations of atrazine herbicides can include:
- Liquid suspension or flowable formulations (such as 4L or 4F): Atrazine particles are suspended in a liquid and diluted with water before spraying. “4L” or “4F” generally indicates approximately four pounds of active liquid or flowable ingredients per gallon.
- Dry-flowable or water-dispersible granule (such as 90DF or 90WDG): These are concentrated dry granules that break apart and form a suspension when mixed with water. An EPA-approved Atrazine 90DF label identifies the product as a water-dispersible granule containing approximately 0.9 pound of atrazine per pound of product.
- Granular turf or fertilizer formulations: Some products contain a small percentage of atrazine distributed on fertilizer or other granules. EPA labels include, for example, an atrazine 1.055% granular herbicide-and-lawn-fertilizer product and granular turf products.
- Combination or premixed formulations: Atrazine may also be manufactured in products containing other herbicides. Examples include atrazine combined with S-metolachlor, acetochlor, mesotrione, or combinations of several active ingredients. These premixes broaden the range of weeds controlled and may include more than one herbicide mode of action.
For an exposure investigation, the exact product name, formulation, percentage of atrazine and EPA registration number can matter because the inactive ingredients and potential routes of exposure can differ between liquid, powder and granular products.
How Atrazine Has Been Applied
Atrazine has generally been applied as a spray to agricultural soil or growing weeds. Liquid formulations are diluted with water, while dry, water-dispersible granules are mixed into a spray tank before application. The mixture is commonly distributed across the field with ground-based boom-spraying equipment. Some product labels have also permitted aerial application under specified conditions, although the approved equipment and method depend on the particular product, crop and label.
Atrazine may be applied at several stages of crop production. A preplant surface application is made before the crop is planted and remains near the soil surface. With a preplant-incorporated application, the herbicide is sprayed onto the soil and then mixed shallowly into it during seedbed preparation. A preemergence or at-planting application is made during or shortly after planting, before the crop and weeds emerge. These soil applications allow atrazine to be taken up as susceptible weeds begin to germinate and grow.
Atrazine has also been applied postemergence, meaning after weeds (and sometimes the crop) have emerged. Postemergence treatments are generally directed at young, actively growing weeds and must be completed before the weeds or crop exceed the size limits stated on the product label. Some labels allow atrazine to be applied with an oil concentrate or surfactant to improve contact with weed foliage.
In addition to being applied alone, atrazine has frequently been used in tank mixtures or premixed herbicide products with other weed-control chemicals. These combinations may control a broader range of weeds and have been used in conventional, minimum-tillage and no-tillage farming systems.
The exact timing, equipment, application rate, mixture and environmental precautions are determined by the EPA-approved label and may also be affected by state or local restrictions.
Government Bans and Restrictions on Atrazine
The use of atrazine has been banned in over 60 countries due to its endocrine-disrupting properties and tendency to contaminate groundwater, but it is still one of the main herbicides used in many regions of the world, including the US and many low- and middle-income countries in Africa, Asia, and Latin America.
The US EPA allows atrazine use, but subjects it to substantial federal restrictions through pesticide labels and drinking-water regulations.
Studies Linking Atrazine to Parkinson’s Disease
Research has raised concern that atrazine exposure may affect biological systems involved in Parkinson’s disease, particularly the nigrostriatal dopamine pathway. Parkinson’s disease is characterized in part by the progressive loss of dopamine-producing neurons in the substantia nigra. Laboratory studies have reported that atrazine can alter dopamine production, storage and transport; reduce dopamine concentrations; affect movement-related behavior; and change molecular markers associated with dopaminergic-neuron injury. More recent studies using human-derived neuronal cells have also reported changes involving alpha-synuclein, tyrosine hydroxylase, neuronal development and other markers relevant to Parkinson’s disease.
A 2024 geographic study of more than 21 million Medicare beneficiaries reported that people living in counties within the highest category of estimated agricultural atrazine application had approximately a 31% higher risk of Parkinson’s disease than those in counties within the lowest category.

Studies Linking Atrazine to Non-Hodgkin’s Lymphoma
Several epidemiologic studies have reported associations between atrazine exposure and the development of non-Hodgkin lymphoma. For example, one study of men in Iowa and Minnesota examined lymphoma tumors according to whether they contained the t(14;18) chromosomal translocation, a genetic alteration commonly associated with certain B-cell lymphomas. Atrazine exposure was associated with a 70% increase in the odds of t(14;18)-positive non-Hodgkin lymphoma. The reported odds ratio was 1.7, with a 95% confidence interval of 1.0–2.8.
Another study evaluated atrazine and nitrate contamination in Nebraska public drinking-water supplies. People whose drinking water contained both atrazine and nitrate had approximately 2.5 times the odds of developing non-Hodgkin lymphoma compared with the reference population. The association was stronger for indolent B-cell lymphoma, for which the reported odds ratio was 3.5. The researchers proposed that atrazine and nitrate could interact in the body to form N-nitrosoatrazine compounds with carcinogenic potential.
In November 2025, the International Agency for Research on Cancer classified atrazine as probably carcinogenic to humans, Group 2A. IARC noted that two case-control studies reported “strong positive associations between exposure to atrazine…and translocation-positive NHL [non-Hodgkin’s Lymphoma]” among exposed farm workers. IARC also noted that there was sufficient evidence of cancer in experimental animals, including increased malignant tumors in female rats. ARC found sufficient mechanistic evidence that atrazine can produce biological effects associated with carcinogenesis (i.e., the formation of cancer), including oxidative stress, inflammation, immunosuppression, receptor-mediated effects and altered cell proliferation or cell death.

Environmental Health Perspectives, 132(2), 027010. https://doi.org/10.1289/EHP13684 | In this prospective cohort study, pesticide applicators younger than 50 years who had ever used atrazine had an increased incidence of non-Hodgkin lymphoma compared with nonusers (RR 2.43; 95% CI 1.10–5.38). The study therefore reported a positive atrazine–NHL association among younger applicators. |
Compensation For Atrazine Injury & Death Claims
Plaintiffs who bring atrazine lawsuits may be able to recover compensation for injuries suffered, including money damages for losses incurred as a result of exposure to atrazine pesticides, such as:
- Pain and suffering
- Mental anguish/emotional distress
- Loss of wages or earnings due to missed work
- Loss of future earning capacity
- Medical care expenses incurred
- Future cost of medical treatment
- Other out of pocket expenses
- Loss of quality or enjoyment of life
- Disability
- Loss of consortium
- Other possible atrazine monetary damages
Certain family and loved ones of individuals who died as a result of atrazine exposure may be able to recover financial compensation from an atrazine wrongful death lawsuit or settlement claim. Atrazine wrongful death lawsuit damages might include, among other things, pecuniary losses suffered by a surviving spouse or next of kin of the deceased family member, such as past and future loss of money or income, benefits, goods, services, and loss of society (i.e., the mutual benefits that each family member receives from the other’s continued existence, including love, affection, care, attention, companionship, comfort, guidance, and protection).
Time Is Limited To File An Atrazine Lawsuit
Deadlines known as statutes of limitation and statutes of repose may limit the amount of time that individuals have to file an atrazine lawsuit to try to recover compensation for injuries they claimed to have suffered (e.g., Parkinson’s disease or non-Hodgkin’s lymphoma) after using or being exposed to atrazine herbicide products.
This means that if an atrazine lawsuit case is not filed before the applicable time limit or deadline, the injured party may be barred from ever taking legal action or pursuing litigation regarding their atrazine injury claim. That is why it is important to connect with an atrazine injury lawyer or attorney as soon as possible.
