The present work was carried out at the seed pathology laboratory of the ?Escola Superior de Agricultura Luiz de Queiroz - ESALQ/USP in Piracicaba-SP and at the experimental field of the ?Centro Nacional de Pesquisa de Hortaliças - CNPH/EMBRAPA? in Brasília-DF. The main objective was to evaluate the effects of the fungicides Captan, Thiram, lprodione, Benomyl and of the mixture Iprodione + Thiram in the control of microorganisms associated with the seeds and present in the soil. The teste of sanity (filter paper + freezing), field emergence and moisture content determination were conducted with four different seed lote of the cultivars Mikado and Pomak, in three times, at three months intentaIs, from november/1988 up to july/1989. The data analysis permitted to obtain the following conclusions: the majority of the tested fungicides gave an excelent control of the main field and storage fungi associated with the seeds, which showed better sanitary quality; the broad-spectrum fungicides like Captan, Thiram and the mixture Iprodione + Thiram gave better field emergence at normal sowing time.
