Further Information

Xylem and phloem-mobile. Adult acute oral toxicity value is from a formulated product, which exhibited more pronounced bee toxicity than the technical active ingredient. EPA (2019) noted that the major degradate X-474 is expected to be highly persistent in aerobic soil/aquatic systems (half-lives of >1000 days in many soils). However, X-474 does not exhibit acute toxicity to the honey bee based on currently available data.
