Study on identification and biological characterization of Fusarium equiseti Corda Sacc. from Euphorbia lathyris

The identification and biological characterization of the pathogen isolated from Euphorbia lathyris induced by Fusarium. equiseti Corda Sacc.was studied in this paper. The results showed that the pathogen was Fusarium.equiseti Corda Sacc. The optimal condition for growing of pathogenic is PDBA、PDA、PSA at 20~25℃and pH 6. The optimum temperature for eonidial germination were 25℃and pH 6,the light-dark alternation was conducive for the mycelial growth and conidial germination.
