| Abstract | ||||
| Sclerotinia sclerotiorum (Lib.) de Bary, the causal organism of bean white mould was isolated from ten different localities assemble seven governorates. It was pathogenic to Giza 3 bean cultivar. Plant water extracts and plan oils severely affected the growth of the causal organism and decreased the disease incidence both under greenhouse and field conditions. Clove oil showed the best effects in this respect. The same results were also obtained by applying calcium salts (100, 200 and / or 400 ppm), Trichoderma harzianum and T. hamatum and Bacillus subtilis, ascorbic acid, salicylic acid, Rizolex and Topsin M-70. Applying such compounds in the field minimized the disease incidence and increased yield production, significantly. Chemical analysis proved that the infected plants has significantly lower chlorophyll pigments and NPK contents. | ||||
