Bacterial Infection
Our analysis of 1 verified rescue cases across 1 plant species shows exactly what causes bacterial infection and the most effective fixes.
Quick Summary
Bacterial leaf spot on pothos caused by Xanthomonas campestris or Pseudomonas species introduced through contaminated water, infected propagation material, or contact with infected plants. Bacteria enter through stomata or wounds and multiply in intercellular spaces, producing water-soaked lesions that may ooze bacterial exudate under humid conditions.
Most Effective Solutions
- 1 Sterilize pruners with 70% isopropyl alcohol before and after each cut to prevent spreading bacteria between plants
- 2 Remove all affected leaves at the base by cutting the petiole close to the stem; dispose of infected tissue in sealed bag away from plants
- 3 Apply copper-based bactericide (copper sulfate or copper hydroxide) following label directions for houseplants; repeat every 7-10 days
