Abstract:
Tomato gray leaf spot was used as object,the pathogen of tomato gray leaf spot in Chifeng were studied by morphological,pathogenicity testing and molecular sequence analysis.The results showed that conidia were light brown,rectangle or cylindrical,size was(21.4-71.9)μm×(10.5-27.3)μm.After spraying inoculation with spore suspension,typical spots appeared on the leaves of tomato in 7 days.PCR product were sequnenced after BLAST analysis,rDNA ITS and gpd of ZTWYF16081515 revealed 100% nucleotide identity to that of S.solani.It came into conclusion that the pathogen causing leaf spot of tomato in Chifeng to be identified as S.solani.
