Abstract

The pathogenicity of Egyptian and German isolates of soil-borne root rotting fungi to seedlings of three cultivars of sugarbeet in presence or absence of different concentrations of either NaCl or CaCl2 were studied under greenhouse conditions. In the absence of salt treatments Egyptian isolates ofRhizoctonia solani were most virulent on all sugarbeet cultivars followed bySclerotium rolfsii andFusarium oxysporum f. sp.betae, the latter proved to be a weak pathogen. The results also revealed that the German isolates ofSclerotinia sclerotiorum were pathogenic to all sugarbeet cultivars studied, whileBotrytis cinerea was only a weak pathogen. However, the presence of salts, NaCl or CaCl2, in different concentrations seemed to cause alterations in such pathogenicity.
