Wisner Baum is investigating Ortho Weed B Gon and other Ortho weed killers manufactured with the chemical 2,4-D (2,4-dichlorophenoxyacetic acid). Published studies have found associations between these weed killers and non-Hodgkin lymphoma (NHL), a cancer of the lymphatic system, which is the network of vessels and glands that helps the body fight infection.
This is an early-stage, emerging investigation. If you used an Ortho 2,4-D weed killer and were diagnosed with non-Hodgkin lymphoma, you may be able to pursue compensation in an Ortho Weed B Gon lawsuit.
Wisner Baum attorneys are investigating Weed B Gon weed killers made and sold under the Ortho brand by The Scotts Miracle-Gro Company. These products remain widely available to homeowners, landscapers, groundskeepers, farm workers, and others.
For decades, people have sprayed Ortho Weed B Gon on lawns and gardens, often without gloves, a mask, or any warning that the active ingredient has been flagged as a possible carcinogen by the World Health Organization’s International Agency for Research on Cancer (IARC). People who used these products and were later diagnosed with non-Hodgkin lymphoma are now asking whether the weed killer is to blame.

July 15, 2026: Wisner Baum is actively reviewing and accepting potential claims from people diagnosed with non-Hodgkin lymphoma after regular use of Ortho weed killers containing 2,4-D. As of July 2026, no multidistrict litigation (MDL) and no class action has been created specifically for Ortho or 2,4-D non-Hodgkin lymphoma claims. This is a developing litigation.
You may qualify to pursue an Ortho Weed B Gon claim if the following apply. A confidential review with our team is the only way to know for sure.
If you are not sure which Ortho products you used, or whether the one you used contained 2,4-D, do not worry — our team can help you obtain records and confirm eligibility. If a loved one died from non-Hodgkin lymphoma after using these products, you may be able to bring a wrongful-death claim on their behalf.
Ortho Weed B Gon is a line of lawn weed killers sold in hardware stores, garden centers, and big-box retailers across the country. The products are designed to control common lawn weeds, including dandelions, clover, crabgrass, and other broadleaf and grassy weeds. Weed B Gon is available in several formulations, including ready-to-use sprays and concentrated products.
The Ortho brand is owned by The Scotts Miracle-Gro Company, headquartered in Marysville, Ohio, which acquired the Ortho consumer lawn-and-garden business from Monsanto in 1999. The products are sold through Scotts subsidiaries, including The Scotts Company LLC and The Scotts Company doing business as The Ortho Group.
Ortho products that have listed 2,4-D as an active ingredient include, among others:
The active weed-killing ingredient in many Ortho Weed B Gon and Ortho WeedClear products is 2,4-D, a chlorophenoxy herbicide first introduced in the 1940s. It remains one of the most widely used weed killers in North America, despite safety concerns. In Ortho formulas, 2,4-D is frequently combined with other herbicides such as mecoprop-p (MCPP-p) and dicamba.
Wisner Baum is investigating Ortho Weed B Gon claims because we believe corporations should be held accountable when they sell a product the World Health Organization's cancer agency has flagged as a possible carcinogen.
The heart of these claims is simple. Researchers began tying 2,4-D to non-Hodgkin lymphoma in the 1980s. The World Health Organization's cancer agency reviewed that research and flagged the chemical in 2015. Ortho weed killers are sold in ready-to-use bottles to homeowners who have no training, no protective equipment, and no reason to think the bottle in their garage is anything but safe.
Our attorneys are focusing on these potential allegations:
Ortho 2,4-D non-Hodgkin lymphoma litigation is in its earliest stage. As of July 2026, there is no MDL (multidistrict litigation — a process that groups similar federal cases before one judge for efficiency) and no class action dedicated to these claims. Cases are expected to proceed as individual personal-injury lawsuits, which may later be coordinated if enough are filed.
The most closely related example to this emerging litigation is the Roundup cancer litigation, which involves a different chemical — glyphosate, not 2,4-D — but the same core question of whether a weed-killer maker should answer for a possible link to non-Hodgkin lymphoma. In the Roundup cases, juries returned some of the largest product-liability verdicts in U.S. history, and the litigation has since moved toward large-scale settlements. Wisner Baum played a central role in that fight, and we are eager to help individuals with their claims against Ortho.
People ask whether these types of cases are part of a “class action.” Ortho Weed B Gon lawsuits are individual cases that may be consolidated into a mass tort. The distinction between these two types of lawsuits is important because it affects what people can recover if their claims are successful.
In a class action, one lawsuit represents a large group with nearly identical claims, and everyone shares a single outcome. That works well for, say, a refund on a mislabeled product. It works poorly for cancer claims, because each person’s diagnosis, exposure, and losses are different.
In a mass tort, each person keeps their own individual lawsuit and their own potential recovery, even if the cases are coordinated for efficiency. Ortho 2,4-D claims are expected to follow the mass-tort model — the same model used in the Roundup litigation — so that each person’s compensation reflects their own circumstances, not an average split among thousands.
No. There is no Ortho Weed B Gon settlement and no verdict yet because this litigation is just beginning. Anyone claiming to know what an Ortho 2,4-D case is “worth” is guessing. The value of any individual claim depends on facts that are unique to each person — the type and severity of the lymphoma, the length and intensity of 2,4-D exposure, medical costs, lost income, and more.
The concern about 2,4-D and cancer comes from decades of published research and from the world’s leading cancer-research body.
In 2015, the International Agency for Research on Cancer (IARC) — the cancer arm of the World Health Organization — classified 2,4-D as "possibly carcinogenic to humans" (Group 2B), publishing its full review in IARC Monographs Volume 113. The working group found strong evidence that 2,4-D causes oxidative stress — cell damage from unstable molecules — a mechanism that operates in humans, and moderate evidence that it can suppress the immune system.
Less widely reported is what IARC's own scientists found when they pooled the human studies. Combining 15 studies of people exposed to 2,4-D, the working group calculated a 31% higher risk of lymphoma and related blood cancers — a relative risk of 1.31, with a 95 percent confidence interval of 1.10 to 1.56. Because that entire range sits above 1.0, the finding is statistically significant.
2,4-D belongs to a family of chemicals called phenoxy herbicides. Researchers have studied this family’s link to non-Hodgkin lymphoma since the 1980s. Among the most frequently cited studies:
Later work has continued to examine the question across larger populations, including the U.S. Agricultural Health Study, the AGRICOH pooled international cohort (Leon et al., 2019), and an InterLymph pooled analysis of occupational herbicide use across ten case-control studies (De Roos et al., 2022).
People who file Scotts Weed B Gon claims may be able to seek compensation for the harm the diagnosis has caused. Depending on the case, that can include:
In cases where a company’s conduct is found to be especially egregious, juries can also award punitive damages meant to punish and deter. Whether any of these apply, and in what amount, depends entirely on the facts of the individual case.

Wisner Baum has spent nearly four decades taking on powerful corporations on behalf of people who were harmed — and winning. Since the firm’s founding in 1985, its attorneys have earned more than $4 billion in verdicts and settlements, represented more than 20,000 families and clients nationwide, and tried hundreds of cases in court.
The firm’s experience is directly relevant to this emerging tort. Wisner Baum was at the forefront of the Roundup weed-killer litigation, cases raising similar questions about an allegedly harmful product linked to non-Hodgkin lymphoma.
In Pilliod v. Monsanto Company, a California jury in May 2019 ordered Monsanto to pay $2.055 billion to Alva and Alberta Pilliod, a married couple who both developed non-Hodgkin lymphoma after years of Roundup use (the court later reduced the award to $86.7 million). Wisner Baum’s managing partner, R. Brent Wisner, served as co-lead trial counsel, and attorneys Michael L. Baum and Pedram Esfandiary served on the trial team.
In an earlier case, Johnson v. Monsanto, Wisner and co-counsel helped secure a landmark verdict for a school groundskeeper with terminal non-Hodgkin lymphoma worth $289 million. The court later reduced the award to $78.5 million, and the Court of Appeal further reduced the total to $20.5 million.
Prior results do not guarantee a similar outcome in any future case — every case is different and depends on its own facts. But they show what our firm is capable of: when powerful systems fail, Wisner Baum steps in, exposes injustice, demands accountability, and fights for real results for the people who were harmed.
You do not take on any financial risk to work with us. Wisner Baum handles these cases on a contingency-fee basis, which simply means that you owe no attorney’s fees unless we are successful in obtaining compensation for you. Contact us at (310) 207-3233 to discuss your claim today.
"Wisner Baum gave exceptional attention to all aspects of the case, detailed inquiry, and tenacious overview of all the information submitted. The paralegals are efficient and diligent. I was completely surprised to find an empathic personal message to take care of my own health during the challenging time of being a full-time caretaker.*"
In May of 2019, the jury in the case of Pilliod et al. v, Monsanto Company ordered the agrochemical giant to pay $2.055 billion in damages to the plaintiffs, Alva and Alberta Pilliod, a Bay Area couple in their 70s. R. Brent Wisner served as co-lead trial attorney for the Pilliods, delivering the opening and closing statements and cross-examining several of Monsanto’s experts. Wisner Baum managing shareholder, Michael Baum and attorney Pedram Esfandiary also served on the trial team in the Pilliod case.
The judge later reduced their award to $87M. Monsanto appealed the Pilliod’s verdict which the California Court of Appeal for the First Appellate District denied on August 9, 2021. Monsanto then requested the California Supreme Court review the appeal’s court decision, which the court denied on Nov. 17, 2021. Monsanto (Bayer) then submitted a petition for a writ of certiorari with the U.S. Supreme Court which SCOTUS denied on June 27, 2022, allowing the final judgment of $87M to remain intact.
$289.2 million jury verdict in Monsanto Roundup trial
Wisner Baum co-represented Dewayne “Lee” Johnson in the first Roundup cancer lawsuit to proceed to trial. On Aug. 10, 2018, a San Francisco jury ordered Monsanto to pay $39.25 million in compensatory damages and $250 million in punitive damages to Mr. Johnson, a former groundskeeper who alleged exposure to Monsanto’s herbicides caused him to develop terminal non-Hodgkin lymphoma.
Months after the jury verdict, the judge overseeing the trial reduced the punitive damages to $39.25 million. Mr. Johnson decided to accept the remittitur, bringing the adjusted amount awarded to Mr. Johnson $78.5 million.
Monsanto (Bayer) appealed the verdict and Johnson cross appealed. On July 20, 2020, the First Circuit Court of Appeals upheld the verdict against Monsanto but reduced Mr. Johnson’s award to $20.5 million. The company chose not to take the case to the U.S. Supreme Court, ending the litigation.
In 2016, Wisner Baum attorney Timothy A. Loranger and six other attorneys in the Plaintiffs’ Management Committee were able to secure a $265 million settlement for victims of the 2015 Amtrak 188 derailment in Philadelphia, one of the largest in the U.S. for 2016.
It is an emerging investigation into whether Ortho weed killers containing 2,4-D can cause non-Hodgkin lymphoma, and whether the manufacturer should be held accountable for how it designed and manufactured the products. Wisner Baum is investigating and accepting potential claims from people diagnosed with NHL after using these products.
2,4-D (2,4-dichlorophenoxyacetic acid) is a widely used weed-killing chemical. It is listed as an active ingredient in many Ortho Weed B Gon and Ortho WeedClear products, often alongside other herbicides such as mecoprop-p and dicamba.
You may be able to. Generally, this investigation is reviewing people who personally used an Ortho 2,4-D product at least 20 days a year for a year or more, who were diagnosed with non-Hodgkin lymphoma, and whose timing fits the two-year and 15-year windows described above. A free case review is the only way to know if you qualify.
No. As of July 2026, there is no settlement, no verdict, no MDL, and no class action specific to Ortho 2,4-D claims. This is an early-stage litigation, which is why acting now can be an advantage.
Roundup cases involve a different chemical — glyphosate. Ortho Weed B Gon claims involve 2,4-D. The two are separate products with separate science, but both allege the products are linked to non-Hodgkin lymphoma.
Nothing up front. Wisner Baum works on a contingency-fee basis, so you pay no attorney fees unless the firm obtains compensation in your case. The initial case evaluation is always free and confidential.
It depends on your state and the type of claim. Deadlines can be short, and once the statute of limitations passes, you usually lose the right to file. Contact us as soon as possible so a deadline does not cost you your claim.
