Avocado scab
Raised brown corky scabs form on young fruits and leaves and later merge into rough patches on the skin.

When to act
In wet weather, check new leaves and young fruit every week from fruit set. Act when the first raised corky spots appear on young fruit. Older fruit no longer catch scab.
What to spray
Active ingredients only, never brands. The FRAC group tells how it works: switch to a different group next time, so the disease does not learn to survive it. Spray only when the damage is worth the cost, and only with products registered with the Fertilizer and Pesticide Authority for your crop. Follow the label. The Shopee and Lazada links only show who sells something with that active ingredient, not a recommendation of any seller or product.
How to prevent it
- Prune to open the canopy so leaves and fruit dry quickly after rain.
- Pick off and burn scabby fruit and leaves, and rake up the fallen ones.
- Water at the base, not over the canopy.
- Plant less susceptible varieties where scab is common.
