Implication

Field measurements reveal pesticide drift and dissipation patterns in winter cereals, suggesting regulatory models may overlook real-world complexities.

Key Points

This study investigates the real-world drift and dissipation of pesticides, focusing on their environmental impact.
Field application of one insecticide (pirimicarb) and three fungicides (bixafen, fluopyram, prothioconazole) under agricultural best practices.
Assessment of drift deposition at 1, 5, and 20 meters downwind using environmental samples and Petri dishes.
Monitoring of dissipation over 128 days using high-performance liquid chromatography and the MITAS model.
Relative drift deposition rates in environmental samples exceeded benchmark values but not in Petri dishes.
Dissipation in in-field soils was faster than literature-based DT 50, while vegetation samples aligned with literature findings.
Off-field samples showed specific dissipation patterns with slower or undetectable rates.
