Spray Drift Public Liability Insurance Claim – Cotton Crop Damage
The Challenge:
A farm operator was alleged to have caused damage to a neighbouring cotton crop through spray drift during a summer fallow herbicide application. The claimant, represented by solicitors, asserted that 2,4‑D applied by our client’s insured party had drifted onto cotton paddocks, resulting in crop damage and loss. The matter was high‑risk, involving a sensitive crop, solicitor‑driven allegations, and potential exposure under a public liability policy.
Our Approach:
We undertook a detailed, evidence‑based investigation combining spray application expertise, agronomic knowledge, weather analysis, and satellite imagery to independently assess causation.
Our investigation included:
- Detailed review of spray records, equipment configuration, and chemical labels
- Analysis of multiple weather data sources and wind vector mapping
- Assessment of temperature inversion risk at the time of application
- Independent evaluation of herbicide symptomology and timing of damage onset
- Use of NDVI satellite imagery to assess crop health before and after the alleged event
- Review of third‑party communications and timelines to test consistency of allegations
This multi‑layered approach allowed us to test the allegation against objective, real‑world evidence, rather than assumptions apparently made by the claimant.
The Outcome:
Our specialist understanding of spray application practices, herbicide behaviour, cotton agronomy, and regional seasonal conditions enabled us to critically assess whether the insured’s spray operation could have caused the alleged damage.
The evidence demonstrated that:
- Wind direction was consistently away from the affected cotton paddocks during spraying
- Wind speeds were above levels conducive to inversion formation
- The insured used appropriate drift‑reducing equipment and compliant practices
- Herbicide damage was evident prior to the insured’s application, supported by dated third‑party communications and satellite imagery
- The timing of reported symptoms was inconsistent with damage from the insured’s application
- On the balance of probabilities, the insured’s spray operation was not the source of the damage.
As a result:
- Liability was successfully refuted
- Claim denial was recommended
- Exposure was effectively reduced to nil, avoiding unnecessary settlement or litigation
Bottom Line:
Specialist agricultural, agronomic and spray‑drift knowledge allowed unsupported allegations to be dismantled using objective evidence, protecting the insured from an unfounded liability claim.
