Pest identification
What's eating my sylvester date palm?
Red palm weevil (Rhynchophorus ferrugineus)
Signs: Larvae tunnel into the crown; fronds collapse inward, fermented smell from the trunk, ultimately tree death
Control: Apply systemic insecticide drenches (imidacloprid) around trunk; use pheromone traps to catch adults; remove and destroy infected palms promptly
Scale insects (including parlatoria scale)
Signs: Grey or white encrustation on fronds; yellowing, reduced vigour, and sooty mould on surfaces
Control: Apply horticultural oil spray; heavy infestations may require systemic insecticide; prune severely affected fronds
Palm aphids (Cerataphis brasiliensis)
Signs: Flat, disc-like aphids on frond undersides; sticky honeydew attracts sooty mould and ants
Control: Strong water jets to dislodge colonies; insecticidal soap spray; encourage lacewings and parasitic wasps
Spider mites
Signs: Bronze stippling and fine webbing on leaflets, especially in hot dry weather
Control: Increase irrigation and humidity around the palm; apply miticide or neem oil, covering both frond surfaces
