Pest identification
What's eating my wine fishtail palm?
Palm leaf skeletonizer (Homaledra sabalella)
Signs: Frond leaflets stripped to a dry, papery skeleton from the underside; silky webbing and dark frass trails present.
Control: Apply Bt kurstaki or spinosad spray to the underside of fronds at first larval sign. Remove severely damaged fronds. Repeat sprays every 7–10 days while larvae are active.
Spider mites (Tetranychus urticae)
Signs: Yellow-bronze stippling on leaflets; webbing between leaflets in hot, dry conditions.
Control: Increase irrigation and humidity around the palm. Spray neem oil or abamectin miticide in the cooler part of the day to all frond surfaces; repeat weekly for three applications.
Mealybugs (Pseudococcus spp.)
Signs: Cottony white masses at the crown and along petioles; sooty mold on honeydew below.
Control: Jet-wash the crown with water. Apply insecticidal soap or neem oil spray, ensuring coverage of leaf bases. Release Cryptolaemus montrouzieri for biological suppression in warm climates.
