SUMMARY
Allidochlor is herbicide that is not generally approved for use in the developed world. It has a high potential for bioconcentration, has a moderate mammalian toxicity and a known skin and eye irritant. Allidochlor is highly soluble in water and highly volatile. It is not persistent in the soil but is mobile. It is moderately toxic to fish. GENERAL INFORMATION
