What is Privet Rust?
Privet rust is a fungal infection caused by Puccinia spp.. It primarily affects privet plants, leading to orange or rust-colored pustules on leaves and stems. The disease can spread rapidly in humid or wet conditions, compromising the plant’s health if not managed promptly.

- Leaf drop or defoliation in severe cases
- Stunted growth or weakened stems
Conditions Favoring Privet Rust
Privet rust thrives in specific conditions:
- High humidity and moisture
- Wet weather or frequent rain

Preventing Privet Rust
Prevention is the best strategy. Consider these practices:
- Ensure proper spacing between plants for good air circulation
