What's eating my silver mediterranean fan palm?

Red palm weevil (Rhynchophorus ferrugineus)

Signs: Adults bore into the crown; larvae tunnel through the trunk causing collapse of the spear leaf and eventually the whole growing point.

Control: Apply imidacloprid or thiamethoxam systemic drench preventively in affected regions (EU/Mediterranean). Use pheromone-baited traps and report suspected cases (notifiable in many EU countries).

Scale insects

Signs: Waxy brown or grey armoured scales encrust petioles and leaf midribs; foliage yellows and honeydew accumulates.

Control: Scrub off with soapy water and a brush; treat with horticultural oil in spring and summer. Systemic insecticide for heavy infestations.

Palm aphids

Signs: Flat colonies under leaflets and around the crown; honeydew and sooty mould on leaf surfaces.

Control: Strong water jets to dislodge; insecticidal soap spray. Encourage hoverflies and ladybirds in the garden.
