pests on Anthurium
Quick answer
If your Anthurium has pests, the most likely cause is: Xanthomonas phaseoli and related pathogens infect Anthurium through wounds or natural openings, causing water-soaked lesions, leaf spots, and systemic decline; strains cluster specifically within Araceae family showing host-pathogen specificity (PMID 38568984).
Start here:
- 1. Isolate infected plant immediately to prevent spread to other aroids
- 2. Remove and destroy all infected leaves with sterile shears; do not compost
