Abstract Patchouli is the source of an essential oil known as patchouli and it has a pivotal contribution to increase national income in Indonesia. However, this plant vulnerable wilt disease caused by fungi, bacteria nematodes, contributing losses quality quantity production. This review aimed at providing information about these destructive pathogens their effective controls.

F. attacks roots, triggering root rot, necrotic wilt, resulting plant’s death. R. colonized stems creating color alteration leaves, stunted growth, rot during midday. These pathogenic organisms can be controlled applying preventive measures, biocontrol agents biopesticides.
