Acute Toxicity of Hexaconazole on Freshwater Fish Channa punctatus (Bloch)

Abstract

The present study was carried out to investigate the lethal toxicity and stress of commercial formulations of hexaconazole, ((RS)-2-(2,4-dichlorophenyl)-1-(1H-1,2,4-triazol-1-yl) hexan-2-ol) fungicide, toward freshwater fish Channa punctatus (Bloch). Estimated 96-hour LC50 of hexaconazole was found to be 103.27 μl/L. On the basis of the obtained LC50 values for 96-hour exposure intervals, hexaconazole can be rated as highly toxic to C. punctatus, with significant changes observed behaviour of fishes. The estimated safe levels showed large variations for the test pesticide.
