'''Texas root rot''' (also known as '''Phymatotrichopsis root rot''', '''Phymatotrichum root rot''', '''cotton root rot''', or, in the older literature, '''Ozonium root rot''') is a
[[pathogen|disease]] that is fairly common in [[Mexico]] and the southwestern [[United States]] resulting in sudden [[wilting|wilt]] and [[death]] of affected [[plant]]s, usually during the warmer months.  It is caused by a soil-borne [[fungus]] named '''''Phymatotrichopsis omnivora''''' that attacks the [[root]]s of susceptible plants. It was first discovered in 1888 by [[Louis Hermann Pammel|Pammel]] and later named by [[Benjamin Minge Duggar|Duggar]] in 1916.<ref name=":3">{{Cite web|last=Damicone|first=John P|date=January 2014|title=Phymatotrichum Root Rot|url=http://pods.dasnr.okstate.edu/docushare/dsweb/Get/Document-2321/F-7621web.pdf|access-date=December 1, 2016|website=Oklahoma Cooperative Extension Service}}</ref><ref name=":1" />
