Abstract

Soil amendments play an important role in management of pesticide residues. Present study reports the effect of biocompost-amendment on degradation of penconazole and propiconazole (triazole fungicides) in a sandy loam soil under flooded and nonflooded (60% water holding capacity) conditions. Penconazole degraded at faster rate than propiconazole. Both the fungicides were found to be more persistent in flooded soil than nonflooded soil, but application of biocompost at 2.5% and 5.0% levels enhanced their degradation under both moisture regimes.
