Phymatotrichopsis omnivora is a soil-borne fungus primarily found in warm, alkaline soils, which can lead to sudden plant death and root decay. The pathogen spreads through soil and root contact, survives for years via sclerotia, and is very difficult to manage once established.
Mainly affects cotton but can infect over 2,000 dicot species, causing major losses in crops and ornamentals, while monocots are largely immune.
