Abstract:

To elaborate the ecological exposure risk and environmental fate of a novel pyrazole amide fungicide penthiopyrad, the authors summarized the synthesis path, biological activity, ecological toxicology, analytical methodology and environmental fate of penthiopyrad, as well as its application prospects. Penthiopyrad exhibited a significant inhibitory effect on fungal spore germination, and the prevention effect was better than the treatment effect. High ecotoxicity of penthiopyrad was observed to aquatic organisms, whereas obvious enantioselective differences were demonstrated to cell viability and oxidative stress. Further studies were recommended to investigate the fate characteristic and aquatic ecotoxicology of penthiopyrad under various circumstances, especially focus on the molecular mechanism of enantioselectivity. The chiral enantiomer of penthiopyrad with high-activity and low-risk was also explored to develop a scientific and accurate risk assessment system, and to reduce the high potential exposure risks to aquatic biological safety and human reproductive health.

Key words: penthiopyrad, synthesis path, biological activity, ecological toxicology, environmental fate
