Legend fungicide registered – updated restriction on use

Legend fungicide has been granted registration by the National Registration Authority for the control of powdery mildew in grapevines.

Legend is a Dow AgroSciences product, containing the active constituent quinoxyfen. Quinoxyfen is a Group M (phenoxy quinoline) fungicide.

Restriction on use for export grapes: Use no later than the commencement of veraison (E-L stage 34), but do not use later than 42 days before harvest.

Note: E-L 34 is the grapevine growth stage when berries begin to soften and brix starts increasing. Refer to Coombe, B (1995) Grapevine growth stages – The modified E-L system. The Australian Journal of Grape and Wine Research (1) pp 100-110.
