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.^[5]

Environmental behaviour

Allidochlor is highly volatile and likely to bioconcentrate.^[6] Residue in leeks, treated with up to 3 applications of 7 kg/Ha of allidochlor, was under 100 ppb.^[5]

Formulations

Formulations of allidochlor have been marketed as "Randox", "Randox T", "Actox Granular", "Vega-Rand" and "Cdaa 20 G", usually supplied as emulsifiable concentrate.^[1]
