First report of maize ear rot caused by Fusarium concentricum in China.

Abstract

Maize ear rot caused by Fusarium spp. causes yield losses and can involve mycotoxin contamination. In July 2018, a survey was conducted during the late milking stage in Guangxi Zhuang Autonomous Region, China. Incidence was 3-25% in surveyed fields. Diseased ears with similar symptoms caused by Fusarium spp., including kernels covered with white, pink, or salmon-colored mold, were collected for analysis. The causal pathogen was isolated and identified as Fusarium concentricum based on morphological characteristics, molecular data (sequence analysis of TEF-1α, mtSSU, β-tubulin gene and calmodulin gene (CAM)) and pathogenicity tests. This is thought to be the first report of F. concentricum causing maize ear rot in China.
