First report of Fusarium andiyazi causing sugarcane Pokkah Boeng disease in China.

Abstract

During annual disease surveys from 2013-18, chlorotic and irregular necrotic lesions on leaves were observed on sugarcane growing in major production regions across China. Symptoms resembled those of pokkah boeng disease (PBD), one of the most devastating sugarcane diseases. Disease incidence was estimated at approximately 40% across the survey area. The causal pathogen was isolated and identified as Fusarium andiyazi based on morphological characteristics, molecular data (sequence analysis of translation elongation factor (TEF1), the DNA-directed RNA polymerase II largest subunit (RPB1), and the second-largest subunit (RPB2) genes and phylogenetic analysis) and pathogenicity test. This is thought to be the first report of F. andiyazi causing PBD on sugarcane in China.
