Pathogenicity tests showed that Sclerotium bataticola had a significant effect on seed emergence, followed by Fusarium solani, in seed inoculation experiments. Rhizoctonia solani showed a highly significant effect, followed by Sclerotium betaticola, in soil infestation treatments of Giza 4 and Giza 5 cultivars.
Transmission of Fusarium solani, F. oxysporum, F. moniliforme, Cephalosporium sp. and Verticillium sp. from seed to mature plant of peanut showed that their translocation gradually decreased from the terminal part of the root towards the upper portions of the plants. The five tested fungi were reisolated from all plant portions in Giza 4 and Giza 5 cultivars, except Verticillium sp. while several attempts failed to reisolated it from the middle and upper parts of the stem or shoot tips.
The present investigation studied the detect, identify and survey the seed-borne fungi of local and introduced seeds in Egypt, study the nature of isolated fungi and their effect on peanut plants and elucidate the transmission of some pathogen fungi from seed to mature plant.
