Allidochlor is a herbicide introduced in 1958. It is an obsolete amide herbicide,[4][1] used preëmergently and postemergently.[5]
Allidochlor's HRAC Group is Group 15, Group K3, Group K. (Numeric, Global, Australian)[1]
Application
[edit]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
[edit]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
[edit]Formulations of allidochlor have been marketed as Randox, Randox T, Actox Granular, Vega-Rand and Cdaa 20 G, usually supplied as emulsifiable concentrate.[1]
