What's eating my lamb hass avocado?

Lamb Hass avocados are most threatened by persea mite, which causes widespread leaf bronzing and defoliation. Lace bugs, thrips, and avocado stem borers are also common. Keep trees well-watered and apply horticultural oil or predatory mites to manage infestations before they weaken fruiting wood.

Clusters of necrotic brown spots on upper leaf surfaces; heavy bronzing, premature leaf drop, and reduced fruit set. Introduce predatory mites (Galendromus annectens); apply horticultural oil or sulfur spray in spring before populations peak. Avoid dusty conditions which suppress natural predators.

Stippled, yellow-brown upper leaf surfaces; dark tar-like frass spots on leaf undersides. Spray undersides of leaves with insecticidal soap or neem oil. Natural predators (lacewings, minute pirate bugs) provide good suppression in gardens.

Silvery scarring on young leaves and fruit skin; distorted shoot tips. Apply spinosad or insecticidal soap to new growth. Blue sticky traps help monitor. Encourage predatory insects by reducing broad-spectrum sprays.

Sawdust-like frass at branch crotches; dieback of individual limbs; weakened scaffold branches. Prune and destroy infested wood promptly. Paint pruning wounds. No effective rescue spray; prevention via tree vigor and avoiding mechanical trunk injury.
