Case Study Update: Nannup WA – July 2020

In Western Australia Mark Scott had been experiencing issues with Bryobia mites, apple dimpling bug, WAA, and snails.

Mark used ducks to control the snails. They did a good job but need to be locked up overnight to protect them from foxes.

A green-tip oil spray controlled the Bryobia mites.

WAA were managed by distributing parasitised colonies into hotspots.

Spring beetle was a problem in some varieties but were controlled with spot spraying to limit impact on beneficials.

Alternaria caused 3.2% damage, bitter rot 1%, powdery mildew 0.6%, weevils and mealybugs 0.4% each.
