Yautepec-Jojutla km. However, this ornamental is affected by the disease named corm rot or fusarium yellows, characterized by leaf yellowing, epinasty and wilting, and caused by fungi of the genus Fusarium.
The first objective was to corroborate the pathogenicity of the 45 isolates obtained. The second objective was to identify and characterize morphologically and molecularly by polymerase chain reaction-internal transcribed spacer PCR-ITS, the highly pathogenic isolates and comparatively analyze the fungal species involved with the reference strain Fusarium oxysporum f.
The third objective was to quantify the phorbol esters in Jatropha curcas oil and evaluate their antifungal potential on mycelial growth and conidial germination of different Fusarium species.
Three fungal species were identified in basal stems and damaged corms taken from field plants, namely F. Molecular analyzes corroborated the species identified and their sequences were deposited in the National Center for Biotechnology Information NCBI gene bank.
The percentage of oil obtained was 61. All species identified and the reference strain was sensitive to the 5 mg ml -1 oil concentration. Key words: Corm rot, Fusarium, molecular analysis, phorbol esters, Fusarium development.
Corm rot is caused by Fusarium spp. Members of the genus Fusarium are among the most important plant pathogens worldwide.
Fusarium species are widely distributed in soil and organic substrates and are abundant in cultivated soils in temperate and tropical regions Booth, 1985. Tel: 22 Albores et al.
