SUMMARY

Alloxydim is a post-emergence herbicide that is not approved fpr use in the EU. It is highly soluble in water, volatile and is not normally persistent in either soil or water systems. It has a low mammalian toxicity and is not expected to bioaccumulate. Alloxydim is not highly toxic to most biodiversity.
