Case Study Update: Adelaide Hills – sprays may be causing mite issues and hit parasitoid wasp

Grower name: Joe Ceravolo
Location: Adelaide Hills
What are the main IPDM issues being focussed on? Codling moth, black spot and lightbrown apple moth (LBAM) are under control.
What are you doing currently with IPDM? Trying to capitalise on the low pest and disease populations and attempt to further reduce pesticide use while maintaining effective control and confidence in the approach being taken.
What has worked well? No mite issues but still early in the season. Transform has controlled apple dimpling bug (ADB).
What hasn’t worked well? Transform may be causing some mite issues and may have hit Aphelinus mali parasitoid against WAA. Block where Mastrus was released against codling moth still has virtually no codling moth.
What would you do differently next time? Need more information on the side effects of pesticides on beneficials so we can make better choices to suit the Action Plan.
