(Also known as: coprapidpen; BAS 440 I)

SUMMARY

Afidopyropen is an insecticide. It is moderately persistent in soil and water. It is moderately mobile and may leach to groundwaters. It has a favourable biodiversity toxcityl profile and is not highly toxic to bees. Whilst it has a low oral toxicity to mammals there are some conserns that afidopyropen may be carcinogenic.

Data alerts

The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement.
