Accumulation and transfer of triadimefon and epoxiconazole in rice seedlings were studied,and the effects of these two fungicides on the growth and development of rice seedlings were also investigated.The results showed that triadimefon was easy to transfer in rice plants,while epoxiconazole was mostly accumulated in rice roots.Triadimefon could promote and inhibit the rice growth at the low and high concentrations,respectively.However,the inhibitory effect of epoxiconazole on rice growth was positively correlated with the contaminated concentrations.Compared to the control,H₂O₂ content and SOD activity of plants at the low concentration treatment of triadimefon were reduced the 21.9% and 11.9%,respectively.Whereas,H₂O₂ content and SOD activity at the high concentration treatment were increased by 9.9% and 18.3%,respectively.Compared to the control group,MDA content and SOD activity of the rice seedlings at the high concentration treatment of epoxiconazole were increased by 18.6%and 37.0%,respectively.This study revealed the accumulation and transfer of triadimefon and epoxiconazole in rice plants and the exposure risk as well,and the results provided a reference for the rational use of triazole fungicides in rice production.
