Ulocladium

Ulocladium is a genus of fungi. Species of this genus contain both plant pathogens and food spoilage agents. Other species contain enzymes that are biological control agents. Some members of the genus can invade homes and are a sign of moisture because the mold requires water to thrive. They can cause plant diseases or hay fever and more serious infections in immuno-suppressed individuals.

Species of Ulocladium resemble those of genus Alternaria with which they were once included. Several DNA-based phylogenetic studies place Ulocladium convincingly within Alternaria, suggesting that the latter is the correct classification for these species.[1] However, Ulocladium, unlike Alternaria, do not produce alternariols, tenuazonic acid, altersolanols, or macrosporin.

The species Ulocladium oudemansii is utilised as a biocontrol agent against Botrytis cinerea. The New Zealand company Botryzen (2010) Ltd uses it to control Botrytis bunch rot in the NZ vineyard industry
