Persistence and degradation of chlorothalonil was determined in loamy sand (Hessaraghatta) and clayey (Bellary) soils following soil application @ 100 mg kg−1. The residues of chlorothalonil degraded to non-detectable levels (< 0.002 ppm) in 60 d in loamy sand, while persisted for over 60 d in black clayey soil. The degradation process increased with increase in moisture level. Higher persistence was recorded in black clayey soil than loamy sand soil.
