Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

This study was conducted during the season of 2017-2018 to estimate the changes that might occur in leaves covered with sooty mold in the Omer Al-Mukhtar University periphery, El-Beida, Libya. The results indicated that the disease caused significant reduction in the leaf’s area from 158, 28.8 and 10cm2 in healthy leaves to 126.5, 23 and 7.5cm2 in infected leaves of fig, oleander and olive trees respectively. Also, water content decreased by (52.8%, 51.9% and 43.6%) in infected leaves compared with the healthy ones. Considering the effects on chlorophyll and phenols contents, data showed that sooty mold significantly influenced chl a …
