据了解,美国环境保护署曾于2011年5月11日发布条例,将鳄梨中丙环唑及其代谢物的残留限量定为10ppm,并规定有效期至2013年12月31日。在2013年,美国环保署将其限量有效期延长3年至2016年12月31日。
2014年美国环保署收到一份申请称,由于丙环唑在控制鳄梨疾病过程中发挥重要作用,申请延长其使用有效期3年,最终美国环保署批准将其残留限量有效期延至2019年12月31日。
新条例自发布之日起生效,征求意见截止2017年3月6日。
部分原文报道如下:
This regulation extends a time-limited tolerance for combined residues of the fungicide propiconazole and its metabolites in or on avocado at 10 parts per million (ppm) for an additional 3-year period. This tolerance will expire and is revoked on December 31, 2019. This action is in response to EPA's granting of an emergency exemption under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) authorizing use of the pesticide on avocado trees. In addition, the Federal Food, Drug, and Cosmetic Act (FFDCA) requires EPA to establish a time-limited tolerance or exemption from the requirement for a tolerance for pesticide chemical residues in food that will result from the use of a pesticide under an emergency exemption granted by EPA under FIFRA.
