Abstract

In the springs of 2020 and 2021, with a temperature of 15°C, root rot on garlic were widespread in Enshi, Hubei Province, China. Based on micro-morphological and cultural characteristics, the pathogen was identified as a Fusarium sp. Further, based on multilocus (ITS, EF-1α) phylogenic data, the strains were identified as Fusarium oxysporum. Koch’s postulates were thus fulfilled by pathogenicity tests on garlic seedlings cultured in vitro.   Key words: Garlic, root rot, Fusarium oxysporum.

Highlights

Garlic (Allium sativum L.) is both flavorful and rich in nutrients, and has important medicinal value compared to other vegetables
The sterilized root segments were put on potato dextrose agar (PDA) plates and penta chloro nitrobenzene agar medium (PPA) plates (Fusarium selective medium)
The isolated singlespore Fusarium colonies were inoculated on carnation leaf agar (CLA) medium and Fusarium species were identified through their morphological characteristics (Awere et al, 2021)

Summary

INTRODUCTION

Garlic (Allium sativum L.) is both flavorful and rich in nutrients, and has important medicinal value compared to other vegetables. It has bactericidal, anti-cancer, anticorrosion and anti-aging properties, among others (Yayeh et al, 2021; Oosthuizen et al, 2018). Root rot of garlic occurred more frequently in China, which leads to about 20-30% production loss rate and more than 50% in serious area (Xie et al, 2015). In Shandong (Zhang et al, 2021) and Ceratobasidium sp. In Jinxiang, Shandong, and Feng Counties, Jiangsu (Yin et al, 2020) Garlic root rot symptoms are yellowing leaves, basal stem discoloration and rotten roots found in various provinces in China, caused by fungi such as Pythium sp. in Shandong (Zhang et al, 2021) and Ceratobasidium sp. in Jinxiang, Shandong, and Feng Counties, Jiangsu (Yin et al, 2020)
