Rust spores can travel very long distances and may infect susceptible plants many kilometres from the initial site of infection. However, other factors such as soil type, pH, and moisture, drainage, humidity and exposure to sun and wind will also have a direct effect on your plants survival. The infection appears from spring to summer under humid low light conditions and turf that is under stress or with excessive nitrogen in the soil is more susceptible. Not possible to spray large trees but young plants may be treated with a protectant fungicide such as wettable sulphur.
