white rot
1. A disease of onions, shallots, and leeks, caused by the fungus Sclerotium cepivorum. Leaves of infected plants turn yellow, and a fluffy, white mycelium appears on the bulb. Small, black sclerotia can be seen in the mycelium and these can survive in the soil for many years.

2. A type of timber decay in which the cellulose, hemicellulose, and lignin components of the wood are decomposed, leaving the wood soft, white, and fibrous.
