“…BBSV concentration was determined by indirect ELISA, according to the method described by Elsharkawy and El‐Sawy with some modification. Leaf samples were collected 7 and 14 days after inoculation, ground in 50 m m carbonate buffer (pH 9.6) and added at a final dilution of 1:10 (g tissue per mL buffer) to microtiter plates.…”

“…Using plant extracts in the control of wheat rusts is a modern, advanced and risk-free alternative method of rust management (Jarvis 1988). Several plant extracts are known to play an important role in the management of plant diseases (Ayoub and Niazi 2001;Joseph 2008;Sowjanya and Manohara 2012;Dey et al 2013;Elsharkawy and El-Sawy 2015).…”

Plant extracts are among the biological control agents that directly affect the plant pathogens and can induce resistance in plants against phytopathogens (Mishra and Raja 1999). Recently, plant extracts have gained considerable attention as alternative options to synthetic fungicides and efforts have been made to utilize these extracts in the control strategies against plant diseases (Srivasata et al. 2011; Elsharkawy and El-Sawy 2015). It has been previously proven that plant extracts are effective control agents L EAF rust, caused by Puccinia triticina Eriks., is among the most common wheat rust diseases in Egypt causing major losses in the grain yield. The objective of this study was to evaluate the efficacy of water and 80%-methanol extracts prepared from seven different plants (henna, blue gum, acalypha, chinaberry, pomegranate, basil, and lantana) in controlling the leaf-rust disease of wheat. In an in vitro experiment, all methanol extracts inhibited the germination of the fungus spores by more than 98%, while water extracts were less effective. The methanol extracts of henna, lantana, acalypha, chinaberry, and pomegranate exhibited a 100%-inhibition of spore germination. In addition, no significant differences were recorded between the methanol extracts of these five plants and the synthetic fungicide Fungshou. In a filed experiment, wheat plants were one-and two-time sprayed with henna, lantana, acalypha, chinaberry, and pomegranate water or methanol extracts. The results revealed that all plant extracts not only decreased the disease severity of the leaf rust, but also enhanced the grain yield components including spike weight, the 1000-kernel weight, and the test weight. Furthermore, the two-time spray application was more effective than the one-time spray. Our study indicated that water and methanol extracts of henna, lantana, acalypha, chinaberry, and pomegranate might be utilized for the control of wheat leaf-rust disease as a safe and environmentally friendly alternative to synthetic fungicides.

“…At present, search for natural products, specifically linked to pathogen management in sustainable agriculture is very active (Droby et al, 2009;Sharma et al, 2009). Endeavors have been made to control plant infection by pathogens utilizing plant extracts (Chaudhary and Chaudhari, 2013;Elsharkawy and El-Sawy, 2015). Specific plant extracts having antimicrobial properties comprise numerous secondary metabolites such as alkaloids, flavonoids, glycosides quinones, saponins, tannins and terpenoids (Balakumar et al, 2011;Gillitzer et al, 2012;Sales et al, 2016).…”
