SUMMARY

Ammonium sulphamate is an inorganic general purpose herbicide. It is currently not approved for use in the EU. It is non-volatile and highly soluble in water. It is not expected to persist in soil systems. Ammonium acetate has a low mammalian toxicity and there is some risk of bioaccumulation. It is a recognised irritant. It tends to have a low toxicity to terrestrial and aquatic wildlife.
