What's eating my anthurium faustomirandae?

Anthurium faustomirandae, one of the largest anthuriums with enormous strap-like leaves, is kept in indoor or greenhouse settings. Its vast leaf surface is highly vulnerable to spider mites and thrips, which can cause widespread silvering damage. Mealybugs exploit the large petiole bases. Scale insects may colonize the thick stems over time.

Widespread pale stippling and bronzing across very large leaf surfaces; heavy infestations produce visible webbing Maintain 60%+ humidity, wipe large leaves with damp cloth regularly, apply neem oil or miticide spray

Silver streaks and scarring on new leaf unfurls; distorted emerging leaves and black fecal dots Spray with spinosad or insecticidal soap, particularly on new growth; use blue sticky traps; repeat weekly

White waxy masses at the base of enormous petioles; honeydew leads to sooty mold on lower leaves Dab with isopropyl alcohol, apply systemic neem drench and foliar neem spray weekly

Tan or brown bumps on thick stems and midribs; yellowing and dieback above affected zones Scrape off physically, apply horticultural oil; repeat treatment every 10–14 days for 4–6 cycles
