2.4 Label Law Enforcement, Inspections & Penalties
Key Takeaways
- Under M.G.L. c. 132B §14, knowing violations of pesticide control provisions can trigger criminal fines up to $25,000 and up to one year of imprisonment.
- Federal FIFRA imposes administrative civil penalties up to about $20,000 per violation for commercial applicators, dealers, or registrants; private applicators typically receive a warning letter for a first offense.
- Massachusetts imposes administrative civil penalties under M.G.L. c. 132B §14A of up to $25,000 per violation for commercial applicators, dealers, or registrants, and up to $1,000 per violation for private applicators.
- MDAR inspectors regularly audit applicator records, inspect application equipment, and investigate complaints of pesticide drift, misapplication, and wildlife exposure.
- Intentional and knowing violations of pesticide laws can lead to criminal prosecution in addition to civil penalties, license suspension, or license revocation under 333 CMR 10.10.
Label Law Enforcement, Inspections & Penalties
Enforcement Authority at Both Levels
Violating pesticide labeling instructions is prosecuted at both the federal and state levels. In Massachusetts, the Massachusetts Department of Agricultural Resources (MDAR) acts as the lead agency responsible for enforcing pesticide regulations under the Massachusetts Pesticide Control Act (M.G.L. c. 132B) and 333 CMR 10.00. The federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) is enforced in Massachusetts jointly by MDAR (as the State Lead Agency) and by the U.S. Environmental Protection Agency (EPA).
MDAR Inspections and Investigations
MDAR inspectors regularly:
- Audit applicator records maintained under 333 CMR 10.14, verifying that each application was recorded with the required 11 fields (see Section 1.5).
- Inspect application equipment to confirm that sprayers, nozzles, and PPE are in working order and consistent with label directions.
- Investigate complaints regarding pesticide drift, misapplication, wildlife exposure, and human exposure — including reports from neighbors, employees, customers, and other agencies.
- Sample pesticide products and residues for laboratory analysis when misuse is suspected.
- Issue Letters of Warning, Administrative Orders, Notices of Assessment (fines), License Suspensions, License Revocations, Conditional Licenses, and Administrative Consent Orders (see Section 1.6 for the full framework).
Inspectors may show up unannounced at a job site or schedule an office audit. Cooperative, well-documented responses tend to be treated more favorably; failure to maintain records or refusal to allow inspection typically results in additional charges.
Civil Penalties
Federal (FIFRA)
Commercial applicators, dealers, or registrants can face administrative civil penalties of up to approximately $20,000 per violation (the cap is adjusted periodically for inflation by EPA). Private applicators (such as farmers) typically receive a warning letter for a first offense, with subsequent violations carrying fines up to $1,000+. Federal civil penalties are recovered by EPA.
State (Massachusetts)
Under M.G.L. c. 132B §14A, MDAR may assess administrative civil penalties of:
- Up to $25,000 per violation for commercial applicators, dealers, or registrants.
- Up to $1,000 per violation for private applicators.
Separately, M.G.L. c. 132B §10 authorizes civil penalties of $500 for a first offense and $1,000 for each subsequent offense for certain violations.
Criminal Penalties
Federal (FIFRA)
Knowing and willful violations of pesticide law are prosecuted criminally:
- A commercial applicator can face a criminal fine of up to $25,000 and/or imprisonment for up to one year.
- A private applicator can face a criminal fine of up to $1,000 and/or up to 30 days in prison.
State (Massachusetts)
Under M.G.L. c. 132B §14, knowing violations can lead to:
- Criminal fines of up to $25,000, and/or
- Imprisonment in a house of correction for up to one year.
Criminal prosecution is reserved for the most serious cases — typically involving intentional misuse, falsification of records, or applications that cause injury or environmental damage. The vast majority of cases are resolved through civil penalties, license actions, or consent orders.
License Actions in Addition to Penalties
Criminal and civil penalties are independent of license actions. MDAR can simultaneously:
- Assess a civil fine under §14A,
- Refer the matter for criminal prosecution under §14,
- Suspend or revoke the credential under 333 CMR 10.10, and
- Issue an Administrative Order requiring corrective action.
See Section 1.6 for the license suspension/revocation process and appeal rights.
Case-Settled Enforcement Examples
MDAR's public enforcement action log gives a sense of how label violations are actually charged. A typical entry cites 333 CMR 13.02(6)(b) — application inconsistent with label directions — together with M.G.L. c. 132B §6A (operating without a current license). Companies that fail to keep application records under 333 CMR 10.14 are often charged alongside the underlying label violation, producing stacked penalties that can exceed ,000 in aggregate. Cannabis cultivators in Massachusetts are a recurring enforcement target because they apply pesticides (including those not registered for cannabis) in ways that deviate from label directions; MDAR cites both the misuse and the failure to maintain records under 333 CMR 10.14.
How a Typical Investigation Proceeds
-
Complaint intake — MDAR receives a complaint from a neighbor, customer, employee, or another agency (MassDEP, Department of Labor Standards, EPA).
-
Inspector dispatch — A MDAR pesticide inspector visits the site, photographs the application, interviews the applicator, and requests the application records under 333 CMR 10.14.
-
Document review — The inspector compares the recorded application rate, target pest, and PPE against the EPA-approved label.
-
Sampling — When misapplication or drift is alleged, the inspector may collect leaf, soil, or water samples for the Massachusetts pesticide analysis laboratory.
-
Enforcement decision — MDAR's Pesticide Program staff determines whether to issue a Letter of Warning, Administrative Order, Notice of Assessment, License Suspension, License Revocation, or refer the matter to the Attorney General for criminal prosecution.
-
Right of appeal — The applicator has 21 days from the final determination to request an adjudicatory hearing before the Pesticide Board under 333 CMR 10.15.
-
Settlement or hearing — Many cases resolve through an Administrative Consent Order in which the applicator admits to the violation, pays a reduced fine, and agrees to corrective action (training, supervision, recordkeeping upgrades).
Practical Risk Management
- Treat every label instruction as a legal command — deviation is itself a violation.
- Maintain a defensible 333 CMR 10.14 recordkeeping system (Section 1.5).
- Carry the 333 CMR 10.13 insurance minimums and notify MDAR in writing of any insurance change (Section 1.6).
- Document every customer complaint and any near-miss — the 48-hour MDAR notification window starts when the applicator becomes aware of an incident.
- Respond to MDAR notices in writing within 21 days to preserve appeal rights.
- Never apply pesticides while a credential is suspended, even if an appeal is pending.

Which of the following correctly describes the dual civil penalty structure that MDAR may impose on a commercial pesticide applicator who violates a pesticide label direction in Massachusetts?
During an unannounced MDAR inspection, an applicator admits that the company's spray rig was last calibrated over a year ago and that no daily application log has been kept for the past month. Under the Massachusetts pesticide enforcement framework, which enforcement tools are available to MDAR?
