Pest and Disease Updates

Timely alerts and insights keep growers up to date on key pest and disease threats so they can protect their orchards. 

Managing pests and diseases is critical to the long-term sustainability and profitability of Australia’s apple and pear industry.

APAL works closely with growers, researchers and industry partners to provide timely advice, support integrated pest and disease management (IPDM) practices, and coordinate national efforts to combat threats such as codling moth, Queensland fruit fly and black spot. By sharing the latest research, seasonal insights and practical orchard management tools, APAL helps growers stay ahead of emerging risks and protect orchard health year-round.

Latest alerts and insights

Fresh guidance and in-season actions from APAL and partners.

Cultural control of apple scab (black spot)

Over-winter inoculum in fallen leaves; prioritise leaf removal and early winter actions to reduce spring infections.

IPDM in focus: Queensland fruit fly

Where Qfly is endemic, align trapping and phenology with peak risk periods to improve timing and efficacy.

Seasonal outlook

Use this quick guide to anticipate pressure and plan IPDM actions.

Season Likely pressure Focus actions
Spring Black spot infections; codling moth flights; Qfly ramp-up Protectants; timed CM controls; refresh traps
Summer Qfly peak; secondary black spot; mites Baiting, hygiene, monitoring, conserve beneficials
Autumn Late CM; carry-over risk on leaves Harvest sanitation; leaf-fall management
Winter Over-winter inoculum; CM larvae Remove leaves; prune; review monitoring

Key profiles

Queensland fruit fly (Qfly)

Endemic in NT, QLD, NSW, VIC. Use trapping, SIT programs and strict orchard hygiene.

IPDM in focus

Codling moth (CM)

Key pest except WA (quarantine zone). Control with SIT, mating disruption, and biocontrol.

SIT pilot results

Black spot (scab)

Risk highest in spring rains. Combine sanitation, protectants, and resistance management.
