Abstract

A pot experiment was carried out in a greenhouse at the Faculty of Agriculture (Saba-Basha)-Alexandria University in order to evaluate the effect of two species of mycorrhizae (Glomus intraradiaces (M1) and Glomus macrocarpium (M2)), two genera of bacteria (Bacillus subtilis (B1)and Pseudomonas fluorescens (B2)) and two genera of yeast (Cryptocooccus neoformans(Y1)and Candida albicans (Y2)) as a biological control of white mold of bean disease (Phaseolus vulgaris L. with two varieties Bronco and Contender ) which infected by Sclerotinia sclerotiorum. Two isolates of Sclerotinia sclerotiorum (S4 and S6) were selected. The results of this study suggested that the difference microorganisms which used as bioagents especially AMF first specie (Glomus intraradiaces) was sufficient to inhibit the Sclerotinia isolates. On the other hand, Contender common bean variety was more sufficient than the other variety (Bronco). Also, the first isolate of Sclerotinia (S4) was less dangerous compared with the other isolate (S6). In future studies, the interaction between the bioagents and the host plant are needed to develop much more efficient biological control agents of the related diseases.
