Isolation,Characterisation and Screening of Indoor Agents for the Wilt Disease of Lilium longiflorum
In order to identify the species of pathogenic bacteria responsible for wilt disease of Lilium longiflorum and preliminary screen of agents for the control of this disease.The pathogenic bacteria were isolated and purified from the bulb of diseased Lilium longiflorum by tissue isolation method,and the pathogenicity was identified according to Koch's Rule.The pathogen was identified as Fusarium oxysporum by morphological and multigene phylogenetic analyses.The indoor virulence of six commonly used fungicides was determined by the mycelial growth rate method,among which 450 g/L Prochloraz SC had the best inhibitory effect on Fusarium oxysporum,with an EC5o value of 0.336 mg/L.The study provides a theoretical basis for the control of wilt disease of Lilium longiflorum.
