Dry rot is spread by spores which are present in most buildings. The minimum moisture content of timber for spore germination is 28–30% (lower than other rots), and the relative humidity must be in excess of 95%. Spores are resistant to desiccation and may still be viable for germination when they are several years old. [2]
Dry rot is the term given to brown rot decay caused by certain fungi that deteriorate timber in buildings and other wooden construction without an apparent source of moisture. The term is a misnomer [ 2 ] because all wood decaying fungi need a minimum amount of moisture before decay begins. [ 3 ]

This nematode is able to multiply in dry conditions causing complete rotting tubers, called dry rot, which decreases the commercial value of the tubers. Dry rot of yam occurs in the outer 1–2 cm of tubers. Symptoms of dry rot of yam include necrotic lesions beneath the skin, followed by yellow lesions below the outer skin of the tuber.
