Antifungal effect of three Trichoderma species against the citrus black spot caused by Phyllosticta citricarpa in Tunisia
Abstract Background Citrus black spot (CBS), even recently reported in Tunisia, could be responsible for considerable losses in lemon growing areas. The present study evaluated different Trichoderma species against Phyllosticta citricarpa causative agent of CBS using two assays. Results The obtained...

| description | Abstract Background Citrus black spot (CBS), even recently reported in Tunisia, could be responsible for considerable losses in lemon growing areas. The present study evaluated different Trichoderma species against Phyllosticta citricarpa causative agent of CBS using two assays. Results The obtained in vitro results exhibited the efficacy of these antagonists to reduce P. citricarpa mycelial growth and the inhibition rate values varied. Trichoderma species showed the highest mycelial growth inhibition with 54.33%, noted for P. citricarpa isolate CBS1 treated with Trichoderma atroviride (A3), and 51.76 and 53.51% for P. citricarpa isolate CBS4 confronted with T. atroviride and Trichoderma asperellum, respectively. The in vivo assay on Citrus lemon fruits confirmed the decrease of the lesions development caused by four P. citricarpa isolates. In fact, the decrease varied from 28.28 to 72.83% for the P. citricarpa CBS3 isolate treated with Trichoderma kunmingense and Trichoderma atroviride, respectively. Conclusions Based on the current results, the used Trichoderma species reduced P. citricarpa mycelial growth in vitro and the lesions appearance due to P. citricarpa on Citrus limon variety Eureka. The efficacy varied upon on the antagonist species and pathogen isolates. Thus, they showed a promising potential to be used to control CBS. |
