Enhanced disease susceptibility upon exogenous SA application in different plants

Host plant	Pathogen (infection style)	SA conc. and treatment method	Effect	References
Tomato (Lycopersicon esculentum)	Botrytis cinerea (necrotrophic)	0.05, 0.5, and 2.5 mM	Lesion size are increased by ~325, 416, and 425%, respectively	El Oirdi et al. (2011)
Broad bean (Vicia faba)	Botrytis cinerea (necrotrophic)	0.05–1 mM (under red light = resistance inducing condition)	~746% increase in disease severity by 1 mM SA	Khanam et al. (2005)
		0.05–1 mM (under dark = disease inducing condition)	No significant difference in disease severity upto 1 mM SA
