Abstract:\u00a0<\/strong><\/span><\/p>\n

Olive knot disease, caused by Pseudomonas savastanoi pv. savastanoi, is a disease affecting pomegranate trees in Mediterranean Region. Therefore, this research aimed to study disease\u2019s prevalence, incidence, and severity in some coastal regions. The field survey was conducted during 2023-2024 on 24 pomegranate orchards in Latakia and Tartous provinces on the Syrian coastal region. The results showed that the disease was widespread of 70.83%, as the disease appeared only in 17 fields out of 24. The disease was recorded in both Lattakia and Tartous at 21.5% and 20.77% respectively. The infection average varied from region to another. The highest infection was recorded in Al-Hanady at 52%, while the disease was not observed in Al-Drouqiah and Baamra, The varieties susceptibility to Pseudomonas savastanoi pv.savastanoi varied from one to another, where the French variety was a susceptibility, while the sweet variety was tolerance. On the other hand, the results showed that the pomegranate isolate was able to infect olives, and the olive isolate was able to infect pomegranates, confirming that the pathogen is the same for both tree species, and that pomegranates are one of the hosts attacked by the bacteria, along with olives. the symptoms appeared in Olive more quickly than in pomegranates.<\/span><\/p>\n
