Abstract

Abstract: 【Objective】To identify the pathogen species of carrot root rot in Chifeng and Hohhot, Inner Mongolia, and provide reference for the control of carrot root rot.【Methods】Conventional tissue isolation, morphological observation and molecular techniques were used to isolate and identify pathogen.【Results】Morphological observation and ITS sequence analysis showed that all 5 strains isolated were Fusarium solani, and their pathogenicity verified by inoculated back to carrot.【Conclusion】It was clear that Fusarium solani was the main pathogen that caused root rot of carrot in two regions.

Key words: Carrot, Root rot, Fusarium solani
