Abstract
First report of Fusarium equiseti associated on pecan (Carya illinoinensis) seeds in Brazil.
Abstract
During surveys conducted in Brazil, an elevated incidence of Fusarium sp. was observed during a quality control seed assay of pecan seeds obtained from orchards in the city of Anta Gorda (Rio Grande do Sul, Brazil). Concomitantly, seedlings of this species, cultivated in a nursery, showed foliar necrosis, wilt and root rot. The causal pathogen was isolated and identified as Gibberella intricans based on cultural, morphological, genetic (ITS) and pathogenicity analyses. This is thought to be the first report of G. intricans causing foliar necrosis and wilt on C. illinoinensis in Brazil.
