Antagonism and Antimicrobial Capacity of Epiphytic and Endophytic Bacteria against the Phytopathogen Xylella fastidiosa
2022
Olive quick decline syndrome (OQDS), which is caused by Xylella fastidiosa, poses a severe threat to the agriculture of Mediterranean countries and causes severe damage to the olive trees in Italy. Since no effective control measures are currently available, the objective of this study was the screening of antagonistic bacteria that are potentially deployable as biocontrol agents against X. fastidiosa. Therefore, two approaches were used, i.e., the evaluation of the antagonistic activity of (i) endophytic bacteria isolated from two different cultivars of olive trees (Leccino and Ogliarola salentina) and (ii) epiphytic bacteria isolated from the phyllospheres of different host plant species …
Efficacy of microbial consortia and natural compounds as seed treatment for tomato pathogen management
2022
In this study the efficacy of experimental treatments based on microbial consortia (MC) (beneficial rhizobacteria and fungi, actinomycetes, arbuscular mycorrhizal fungi) and natural compounds (NCs) (chitosan and glucosinolates) as seed treatments for tomato bacterial and fungal pathogens management (Xanthomonas euvesicatoria pv. perforans, Xep; Pseudomonas syringae pv. tomato, Psto; Fusarium oxysporum f. sp. radicis-lycopersici, FORL) was evaluated. Independent trials were performed by using organic tomato seeds ‘San Marzano nano’. Treatments were performed by soaking seeds either in aqueous MC suspensions or NC dilutions. The direct effect on the seed inoculum was performed on seeds inocul…
