| Abstract | ||
| The results of isolation and diagnosis of white mold disease showed that the causal agent is Sclerotinia sclerotiorum (Lib) de Bary. This study is the first experimental record of occurrence of this disease on eggplants in Ninevah province.Two isolates of the pathogen were obtained the first was SSB that isolated from greenhouses in Bashika area and the second was SSC from greenhouses of college of agriculture and forestry. The first isolate was more aggressive than the second one,through the test of the pathogenicity for the two isolates of white mold SSB, and SSC.Infection symptoms appeared as a white mycelium growth. Its appearance like a cotton in an infection sites and then expanded to included large parts of infection area. In the infections areas the leaves were seen in touch with the infected branches, and attacking mold was also seen on the infected branch as mycelium growth observed on the surface of plant.The rsults of pathogenicity tests, revealed that the infection method with maycilium injury exists, recorded the highest average canker and reached 18.58 cm, with no significance from the infection method with sclerotia by injury exists which reached 16.29 cm. The infection with mycelium comes in second rank, with no injury and the average canker long reached 11.75 cm, wheare as the less average in canker long recorded with infection by sclerotia without injury exists and reached 4.81 cm. | ||
