PAGANI, A.P.S; DIANESE, A.C; INACIO, C.A and CAFE-FILHO, A.C. Occurrence of white rust (Albugo ipomoeae-panduratae) on Ipomoea acuminata in the brazilian mid-west. Braz. J. Microbiol. [online]. 2012, vol.43, n.1, pp.306-308. ISSN 1517-8382. http://dx.doi.org/10.1590/S1517-83822012000100036.
Spontaneous plants of Ipomoea acuminata ("morning glory") exhibiting white rust pustules were found in a field crop area of Planaltina, DF, in the fall season of 2010 and the disease causal agent was identified as Albugo ipomoea-panduratae (Oomycota). No reports of the association between A. ipomoea-panduratae and I. acuminata were known in Brazil previously to 2010. A reference specimen was deposited at the University of Brasilia Mycological Reference Collection.
