Persistence of hexaconazole, a triazole fungicide in soils.
Persistence of hexaconazole (2-(2,4-dichlorophenyl)- 1-(1H-1,2,5-triazol-1-yl) hexan-2-ol) was studied in alluvial, red and black soils under flooded and nonflooded conditions. This fungicide was more persistent in all soils under flooded conditions than under nonflooded conditions and at 27 degrees C than at 35 degrees C. Degradation of hexaconazole in sterilized and nonsterilized soils proceeded at identical rates indicating a minor role of micro-organisms in its degradation. The soil persistence of hexaconazole was not affected by the addition of wheat straw both under flooded and nonflooded conditions.
