Rust (Roses) – How to control

Rust (Roses)

Description: Although rust is widespread, it is most consistently

a problem in western states.

Yellow “rust” spots appear on the topsides of leaves

during cool weather in spring or late fall. Infected

leaves become twisted and dry. Spores infect leaves

when rain, dew or fog occurs at temperatures from 55°

to 75°F.

Solution: When rust

is first noticed, pick off and destroy infected leaves

and spray plants with Soap-Shield® Fungicidal Soap*.

Repeat sprays every 7-10 days as long as conditions

favor rust infection. Remove and destroy diseased leaves

and twigs in the fall.
