Английский. Xanthomonas fragariae, causal agent of angular leat spot of strawberry, has been isolated in open-field cultivation of Latium, Campania, Emilia-Romagna and Sicily. The infection has been noted during spring, summer and autumn 1993, on the following cultivars: "Chandler", "Pajaro", "Parker", "Marmolada", "Favette" and "Miss", with the last two more injuried. After the harvesting, all of the vegetative material has been destroyed. The identification has been achieved by means of biochemical and physiological tests, differential growth on selective media as well as pathogenicity tests. Pathogenic activity of the microorganism was present also with low temperatures occurring in Northern Italy during autumn as well as at the beginning of spring in Sicily

Viene segnalata la presenza di Xanthomonas fragariae, agente causale della maculatura angolare delle foglie di fragola, in coltivazioni di pieno campo del Lazio, Campania, Emilia Romagna e Sicilia. L'infezione e' stata riscontrata durante la primavera, estate ed autunno 1993, sulle cultivar "Chandler", "Marmolada", "Pajaro", "Parker", "Favette" e "Miss"; le ultime due erano le piu' colpite. A fine ciclo produttivo, tutto il materiale vegetativo e' stato distrutto. L'identificazione e' stata ottenuta mediante saggi biochimici, fisiologici e crescita su substrati selettivi differenziali, nonche' attraverso prove di patogenicita'. E' stata evidenziata attivita' patogenica del microrganismo anche in presenza di basse temperature autunnali in Italia settentrionale e ad inizio primavera in Sicilia
