In 4 soils treated with imazalil at 0.2mg/kg and incubated under aerobic conditions at 20°C in the dark, CO2 was evolved to a maximum of 3.4-37.9% AR on day 120 (3.2% at 10°C). Since the extraction procedures were probably not exhaustive enough, no reliable assessment can be made on the occurrence of metabolite fractions >5% AR and their maximum levels. Also, reliable DT50 values cannot be determined as it is likely that a significant amount of extractable imazalil was still present in the reported unextractable fraction. Therefore the degradation pathway is not adequately addressed and additional information is necessary.
