Last updated: 05/06/2023
(Also known as: HWH 4991)
Bencarbazone is a post-emergence herbicide. It has a moderate aqueous solubility. There are large knowledge gaps in the public domain regarding its environmental fate parameters. It has a low mammalian toxicity and would not be expected to bioaccumulate. It has a moderate toxicity to birds, fish, aquatic invertebrates and earthworms.
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.
