PIERI, Cristiane de; PASSADOR, Martha Maria; FURTADO, Edson Luiz  e  CARVALHO JUNIOR, Aníbal Alves. Teak rust (Olivea neotectonae): new occurrences in Brazil and review of its specific name. Summa phytopathol. [online]. 2011, vol.37, n.4, pp. 199-201. ISSN 0100-5405.  http://dx.doi.org/10.1590/S0100-54052011000400006.

The causal agent of rust teak (Olivea neotectonae) has attacked the teak plantations in several countries of world. It causes severe defoliation of the plants contributing to the reduction of photosynthetic area and hence the production. Especially associated with nurseries plants is more severe in plants with less than 10 years of age. The symptoms of infection are seen as brown spots and signs, serum powdery yellow-orange color. In May 2009 these symptoms and signs were observed in leaves of teak coming from the northern state of Mato Grosso, Maranhão, Tocantins and the Midwest state of São Paulo, received by the laboratory of Forest Pathology of FCA-UNESP Botucatu. The aim of this work is to record these observations in the Brazilian states and a brief review on the correct designation of the pathogen.
