Abstract

Occurrence of Ralstonia pseudosolanacearum in sweet pepper (Capsicum chinense) in the state of Pará.

Abstract

In 2015, plants with symptoms of wilt were observed in plantations of sweet pepper (Capsicum chinense) in the municipalities of Castanhal and Santo Antônio do Tauá, Pará, Brazil. Symptomatic plants were collected for pathogen isolation and identification. Based on the results of pathogenicity, polymerase chain reaction and biochemical tests, the causal agent was identified as Ralstonia pseudosolanacearum. Bacterial wilt has already been reported in C. chinense in the Northern Region, with collections carried out mainly in the state of Amazonas. This is thought to be the first report of R. pseudosolanacearum causing bacterial wilt in C. chinense in the state of Pará.
