The Neighbor's Drift Complaint and the Applicator's Records
A commercial applicator in Ohio sprays a 40-acre corn field with a restricted-use herbicide on a windy afternoon. Two days later, a neighboring property owner calls the applicator claiming that herbicide drifted onto her vegetable garden, damaging tomatoes and peppers. The applicator's only documentation is a handwritten note in a pocket notebook listing the date, field, and product name. The applicator holds a valid commercial applicator license. The neighbor has filed a complaint with the Ohio Department of Agriculture (ODA). The applicator insists the wind was within label limits and that no drift occurred.
1. What records should the applicator have kept for this restricted-use pesticide application, and why does the missing documentation matter now that a complaint has been filed?
Read the worked answer
Ohio rules for restricted-use pesticide applications require the applicator to keep records that typically include: the date and time of application; the name and address of the customer/application site; the size of the area treated; the product name and EPA registration number; the amount applied and application rate; the name and license number of the certified applicator; and weather conditions (wind speed and direction, temperature). The pocket note captures almost none of this. Why it matters: when ODA investigates a complaint, the applicator bears the burden of demonstrating the application complied with the label and Ohio law. Without wind speed/direction, rate, and equipment records, the applicator cannot rebut the drift allegation or show the application was made according to label directions. Incomplete records can themselves be a violation independent of whether drift occurred, exposing the applicator to enforcement action even if the neighbor's damage cannot be proven.
2. The applicator wants to argue that because the wind was within label limits, no violation occurred. How should this argument be evaluated?

Label wind limits are a threshold condition, not a safe harbor. Compliance with wind speed does not by itself establish that drift did not occur; drift can result from boom height, droplet size, speed, inversions, or application too close to a sensitive site. The correct analysis is whether the applicator applied the pesticide consistent with label directions and all applicable precautions to avoid off-target movement. If the label prohibited application near sensitive crops or required a buffer, those conditions matter more than the raw wind number. Because the applicator cannot document wind direction, boom height, or buffer distance, the argument is weak. The practical lesson: the applicator should have documented the conditions that support a no-drift conclusion, not just the date and product.
3. What should the applicator do now, and what are the realistic consequences?
Read the worked answer
The applicator should cooperate fully with ODA: preserve the notebook and any sprayer calibration records, reconstruct weather data from the nearest source for the date/time, and avoid contacting the neighbor in a way that could be seen as intimidating. Realistic consequences include an ODA investigation, possible findings of recordkeeping deficiencies and/or label violations, civil penalties, and potential civil liability to the neighbor for crop damage. The applicator's commercial license could be subject to suspension or conditions depending on findings. Going forward, the applicator should adopt a written record form completed at each job and retain records for the period required by Ohio law.
