In: Mansoura University Journal of Plant Protection and Pathology 2011.v.2(1)Summary: This study was designed to investigate the effect of calcium chloride and calcium chelate on the interaction between sugar beet plants and Cercospora leaf spot (CLS) disease as well as its direct effect on the pathogen using scanning electron. microscope. It was clearly observed that, both calcium salts significantly reduced CLS disease severity with calcium chelate being more effective in CLS disease control. The levels of chitinase, ~1,3 glucanase and Polyphenol oxidase (PPO) of the salt¬treated plants were significantly increased as compared to the untreated control. Thus, both calcium chelate and chloride have a role in triggering the induction of plant resistant.
