First report of fig decline caused by Phytophthora niederhauserii in Taiwan.

Abstract

In June 2006 and October 2016, diseased figs (Ficus carica) showing necrosis symptoms on the roots and at least half of the basal stems, leading to wilting and leaf chlorosis were observed in the orchards and garden shops in Changhwa and Yunlin counties in Taiwan. The causal pathogen was isolated and identified as Phytophthora niederhauserii based on morphological characteristics, molecular data (sequence analysis of the ribosomal DNA internal transcribed spacers and cytochrome oxidase subunit II and I regions) and pathogenicity test. This is thought to be the first report of fig decline caused by P. niederhauserii in Taiwan.
