Resumo: | The fungus Sclerotinia sclerotiorum, causal agent of white mold disease on several economically important crops, such as bean, soybean, and cotton, is commonly disseminated through seeds and can cause high losses on their quality and in productivity of these species. The aim of this study was assessing the effects of different initial inoculums potentials of this fungus on common bean seeds using two different strains of the fungus and two genotypes of common beans (Pérola and Ouro Negro) artificially inoculated. Seeds were sown on soil and the cultivation was performed under controlled environmental conditions favorable to development of the white mold disease. Variables assessed were: germination; seed health; emergence speed index; initial and final seedling number; and dry weight of aerial parts and roots. It was found that with the gradual increase in inoculum potential in the seeds also occurred gradual reduction in the values of: germination; emergence speed index; seedling stand; and length and dry mass of aerial parts and roots. These results show the importance of initial inoculum potential of S. sclerotiorum present in common bean seeds, as much in disseminating the pathogen as on direct damages caused in field by reducing productive potential of the emerged plants. |
