Several diseases of gladioli now present in Western Australia can be very damaging to the plants under certain conditions. The diseases referred to in this article attack not only the above-ground portions of the plant, but the corms also, and their introduction to new areas usually results from the planting of infected corms. When such corms are planted the disease spreads to the developing shoots and leads to inferior growth and flower production, and in some cases to the death of the plant. An even more serious feature of the disease is that the soil becomes contaminated with the organisms for an indefinite period, making future plantings extremely hazardous unless expensive soil disinfection is carried out.
