Rust is a fungal disease that occurs on turf grasses when their growth is slowed. This usually happens in late summer or early fall, during periods of dry weather or when the grass is low on nitrogen. Lawn rust can weaken the vigor of the grass and open it to other diseases and turf problems.
Furthermore, fungi are also important as parasites and pathogens, which cause diseases to both animals and plants. For example, in humans, fungi cause diseases such as ringworm, athleteâs foot etc. while, in plants, they cause rusts, smuts, stem rot etc. Fungi belong to a single Kingdom called Fungi, whereas parasites belong to several Kingdoms including Bacteria, Protozoa, Fungi and Animalia. â¢ All the parasites cause injuries or diseases to their hosts, whereas only few fungi species cause diseases to human and plants.
