The activity of salts has been well researched and documentedin the literature (Nigro et al., 2006; Qin et al., 2010; Romanazziet al., 2012). Regarding calcium chloride, a complete growth inhi-bition of R. stolonifer was achieved only at 20 g/l. These resultsare in agreement with Youness (2002), who found that differentcalcium salts slightly restricted growth of both R. stolonifer andAlternaria alternata, and El-Gamal et al. (2014), who found thatno complete inhibition was obtained by calcium chloride till 1.5%against tomato decay fungi. The low in vitro efficiency of calciumchloride was expected, since previous researches showed calcium
