GreenCast in Australia

Apply adequate levels of nitrogen and other nutrients.
Remove clippings from turf.
Reduce shade and improve air circulation.
Regulate irrigation to minimise the amount of time moisture remains on the leaf surface.
Water deeply and infrequently.

Fungicidal control

At present there are no Syngenta fungicides with label recommendation for control of rust in turf.

Puccinnnia & Uromyces species

All cool season turfgrass species

The flecks enlarge, elongate, and turn yellow in colour.
The yellowed area of the infected spots enlarges and elongate parallel to the leaf or stem axis as the infection matures.
The leaf blade turns yellow starting at the tip and progressing to the base.
The infected areas rise above the epidemics and then rupture, releasing spores that are yellowish-orange to reddish-brown in colour.
Severe disease infection causes the shoot to turn yellowish to reddish-brown and slows growth.
As individual plants die, the turf thins.

Rust - Aus

Rusts favour moist, low-light areas.
Leaf wetness is required for fungal growth.
Depending on the species, Rusts favour temperatures between 18 C and 30 C.
Severe rust infections occur on slow-growing turfgrass particularly those with low nitrogen levels and/or water stress.

Grasses growing under stressful envrironmental conditions are most easily parasitised by the Rust fungi.
