Plant choices for Phymatotrichopsis-infested areas

The following lists were compiled primarily from “Controlling cotton root rot on ornamental plants” (Texas A&M), “Cotton (Texas) Root Rot” (U of Arizona), Texas A&M PlantAnswers.com, and Wescott’s Plant Disease Handbook.

Warning: due to discrepancies in reporting, some plant species may appear on more than one list.  Even plants that show some level of resistance or tolerance to P. omnivora may become infected and killed, particularly in heavily infested sites or under other stressful conditions.
