Controlling Leaf Fungus on Myrtle (Myrtus communis)

Brown or copper spots on myrtle leaves usually signal a fungal or bacterial infection. The disease spreads via water splash, contaminated tools, or even hands. To manage it:

• Remove infected leaves when foliage is dry; rake and dispose of fallen debris.
• Avoid overhead watering—irrigate at soil level.
• Sterilize pruners with isopropyl alcohol between cuts.
• Wear disposable gloves when handling diseased tissue.
• Apply a copper-based fungicide (like Daconil) according to label directions for persistent cases.

Prevention hinges on good airflow, clean practices, and keeping foliage dry. Regular monitoring catches outbreaks early.
