Rust is a fungal infection that can start rearing its head during Autumn. This nasty disease occurs in both warm and cool temperatures making it a fairly common disease to have all season round. Rust prefers high humidity and heavy rainfall, and can even lie dormant on dead leaves and debris like a silent assassin. Leaving this untreated on your plant can reduce its vigour and will minimise flower production.
Treatment for Rust:
Mix 1 teaspoon of Physan 20 to 1.8 Litres of water and apply several times at 7-10 day intervals when symptoms appear. Be sure to cover the underside and top surfaces of the leaves and branches until thoroughly wet.
Protecting your Plants from Rust is a Must this Autumn!
