Abstract

First report of Pythium myriotylum D., causing damping off and root rot in chili pepper (Capsicum annum L.) from Punjab, Pakistan.

Abstract

During surveys of nine major chili (Capsicum annuum) growing areas of Punjab, Pakistan, from September 2015 to November 2016, disease incidences ranging from 13.8 to 45.4% were recorded. The symptoms consisted of damping off, and on older seedlings (15 to 30 days posttransplanting) reduced growth, wilting, water soaking, brown discoloration, and root rot. Based on morphological characteristics, DNA sequence analysis and pathogenicity tests, the causal agent was identified as P. myriotylum. This is thought to be the first report of P. myriotylum causing damping off in chili pepper crops from Pakistan.
