Chemistry:Allidochlor

From HandWiki

Allidochlor is a herbicide introduced in 1958. It is an obsolete amide herbicide,[1][2] used prёemergently and postemergently.[3]


Application

Allidochlor has been used in Canada, where it was applied at high rates (7 kg/Ha) with much spraywater (500 L/Ha). At the time, 1984, allidochlor was registered for use on onions only in Canada, with leek usage not granted for lack of residue data.[3]

Environmental behaviour

Allidochlor is highly volatile and likely to bioconcentrate.[4] Residue in leeks, treated with up to 3 applications of 7 kg/Ha of allidochlor, was under 100 ppb.[3]

Formulations

Formulations of allidochlor have been marketed as "Randox", "Randox T", "Actox Granular", "Vega-Rand" and "Cdaa 20 G", usually supplied as emulsifiable concentrate.[2]
