“…Aqueous and chloroform extract presented no activity on the test organism and this is in line with the work of other authors which shows that aqueous and chloroform extract of L. inermis had no activity on R. solanacearum [15]; however the aqueous extract of other plant such as Datura, Garlic and Nerium activity were found [17]. This might be due the differences of their phytochemical constituents.…”

“…2 exhibited the highest disease incidence with 97% wilting. Such results agree with previous reports; who mentioned that the different isolates of R. solanacearum were varied in their pathogenicity ( Abo-Elyousr and Asran, 2009 ; El-Ariqi et al . , 2005 ; Galal et al, 2003 ).…”

This study aims to isolate and identify the causal pathogen of tomato bacterial wilt in Egypt. In 2008, tomato plants showing typical symptoms of bacterial wilt disease with no foliar yellowing were observed in Minia, Assiut and Sohag governorates, Egypt. When cut stems of symptomatic plants were submerged in water, whitish ooze was evident and longitudinal sections showed a brown discoloration in the vascular tissues. Bacteria were isolated on triphenyl tetrazolium chloride medium and fifteen isolates shown typical morphological and cultural characteristics were confirmed as Ralstonia solanacearum biovar 2 race 1. Pathogenicity tests showed that all isolates proved to be pathogenic to tomato plants, varied from 52 to 97% wilting. This is the first report of R. solanacearum biovar 2 race 1 causing bacterial wilt in tomato crop in Egypt.

“…Bacterial wilt, caused by members of the Ralstonia solanacearum species complex, is a key emergent disease in non-tropical regions of the world. It can infect over 200 plant species representing over 50 botanical families (Abo-Elyousr and Asran, 2009;Milling et al, 2011;Fujiwara et al, 2012;Aslam et al, 2017). Kim et al (2016) reported that, Bacterial wilt of tomatoes caused by R. solanacearum is a devastating disease that limits the production of tomato in Korea.…”

A survey was carried out to determine the current status of bacterial wilt (Ralstonia solanacearum) disease in major tomato growing areas in Egypt incidence and distribution. In the 2014/2015 cropping season in major tomato growing areas of Upper and Lower Egypt. In upper highest incidence of bacterial wilt occurred in Luxour Governorate (10.29%) and lowest in Al-Giza Governorate (9.41%). Wilt severity was recorded (3.44%) in Luxour Governorate and the lowest (2.60%) was recorded in Sohag Governorate. In Lower Egypt Governorates, the highest disease incidence was recorded in Al-Behiera (15.28%) followed by Al-Daqahlia, (13.23), Al-Gharbia (12.41), Kafr Al-Shikh(12.70) and Al-Sharqia (12.14) Governorates. The lowest disease incidence recorded in Al-Suiz Governorate (10.27%), followed by 11.28, 11.58 and 11.67% in Al-Qalioubia, Al-Ismailia and Al-Minoufia Governorates respectively. The highest bacterial wilt severity was recorded in Al-Behiera Governorate, fields (5.70%), followed by Al-Gharbia (4.60%), while the lowest bacterial wilt severity was recorded in Al-Suiz Governorate (2.63%), followed by 3.30, in Al-Qalioubia Governorate. All the collected plants were subjected to PCR to detect the infected samples. The expected 288 bp amplicon was detected in bacterial wilt infected samples from above mentioned governorates and diseases percentage and severity were calculated.
