The Australian Pesticides and Veterinary Medicines Authority (APVMA) has approved the active ingredient Aureobasidium pullulans for use on wine-grapes. Aureobasidium pullulans (strains DSM 14940 and DSM 14941) is a biological fungicide, sold as ‘Botector’. Botector is registered for control of botrytis bunch rot (Botrytis cinerea) in grapevines and is distributed by Nufarm Australia Limited.
The Botector label recommends up to four applications per season between 80% capfall (E-L 25) and berries not quite ripe (E-L 37). A withholding period (WHP) for Botector is not required when it is used as directed.
