RUST DISEASES
Puccinia spp.

Rust looks as exactly as it sounds with the grass having rust to orange coloration from spores that build up on the blades of grass and are readily seen. This disease is more favorable to warm, damp weather where the grass doesn’t get the chance to dry out as with periods of long lasting dew from up to 10 hours. This is especially favorable on overcast damp days. Any contact moving through the infected areas helps spread the spores. Blue grass and rye grass are the most affected. Proper fertilization and frequent mowing can help with this problem. Chemicals should only be used in severe situations and these are anilazine, chlorothalonil, triadimefon, zineb or maneb.
