Allidochlor is a herbicide introduced in 1958. It is an obsolete amide herbicide, used preëmergently and postemergently.

Allidochlor's HRAC Group is Group 15, Group K3, Group K. (Numeric, Global, Australian)

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.

Environmental behaviour

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

Formulations

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