Herbicide Drift Complaint, Incomplete Records, and an Inspector Visit
On July 12, you apply 2,4-D amine to 40 acres of pasture in Pontotoc County using a 60-foot boom sprayer. The label requires a 100-foot buffer from streams and says not to apply when wind is toward adjacent sensitive crops. At 7:30 a.m., wind is 4 mph from the west, and the forecast is for 12 mph by noon. The pasture's east edge is 150 feet from a creek, and an organic vegetable farm is 1/4 mile east. You finish at 11:45 a.m.; by then wind is 9 mph from the west and temperature is 88°F. At 2 p.m., the organic farmer calls: tomato and pepper leaves are cupped and twisted, and she says she will report you. Your application record shows the product, rate, date, time, and weather but not the buffer distance or the name of the organic farm. The Mississippi Department of Agriculture and Commerce inspector arrives two days later and asks for your records and a written statement.
1. Evaluate whether a label or legal problem exists even though the 100-foot stream buffer was met.

Buffer versus wind direction
The 150-foot distance from the creek exceeds the 100-foot stream buffer, so that specific buffer appears met. But the label also prohibits application when wind is toward adjacent sensitive crops. Wind was from the west, toward the organic farm to the east, at 4–9 mph during the application. That is a separate restriction from the buffer and may have been violated.
Drift evidence
Cupped and twisted tomato and pepper leaves are consistent with 2,4-D injury. The symptoms do not prove the source by themselves, but they make drift plausible and require investigation. The timing, wind direction, and sensitive crop all point to a real risk.
Records
The record lacks the buffer distance and the sensitive-crop identity. That is incomplete documentation and weakens your ability to show compliance. Do not fill in gaps after the fact; document what you actually knew and did.
2. What should you do immediately after the farmer's call and during the inspector's visit?

With the farmer
Stop further spraying in the area. Meet the farmer, inspect the damage, and take dated photos and notes. Listen and gather facts; do not admit liability, argue, or promise a payment. Notify your supervisor and insurer.
With the inspector
Cooperate. Provide the records you have and a factual written statement. Do not alter or destroy original records. Explain the wind, buffer, product, rate, and timing accurately. If you do not know an answer, say so and follow up. Ask about any required state reporting and follow it.
Equipment and cleanup
Check the sprayer for leaks and clean it away from the creek. Do not wash the tank into a ditch or stream. Keep contaminated rinse water contained according to the label and state guidance.
3. What preventive changes should you make before the next application near sensitive crops?
Read the worked answer
Site survey
Before application, identify organic farms, gardens, water, houses, and other sensitive areas within the drift risk zone. Record their locations and distances, not just the field boundary.
Application conditions
Apply only when wind is away from sensitive crops and within the label. Avoid temperature inversions and high-drift conditions. Use drift-reduction nozzles, keep the boom low, maintain the label pressure, and leave an untreated buffer. Consider a coarser droplet spectrum if the label allows it.
Communication and records
Talk with neighbors before sensitive applications. Keep weather records, buffer measurements, product and rate records, and notes on sensitive sites. If conditions change, stop and reassess rather than finishing the field.
