%X In experiments conducted in laboratory, the effect of fungicides, seed dresser adjuvants and storage time in the control of Drechslera teres in seeds of barley cultivar BRS Elis, with 58% incidence, was quantified. Fungicides indicated by barley research (carboxin + thiram, difenoconazole and triadimenol) compared with the mixture carbendazim + iprodione were tested. As seed dresser adjuvants, water (500m mL/100 Kg) and a polymer (150 mL/100 Kg) were used. Treated seeds were stored in paper bags and kept in the refrigerator at 5oC. At 30-day intervals during six months, seeds were plated on semi-selective Reis's medium (1983). The best control was obtained by the mixtures carboxin + thiram and carbendazim + iprodione and the polymer as seed dresser. The control efficiency was improved by the storage time without negatively affecting seed germination. Due to the transmission efficiency, the fungus eradication in seeds should be pursued. Em experimentos conduzidos em laborat車rio quantificou-se o efeito de fungicidas, de ve赤culos de cobertura e do tempo de armazenamento no controle de Drechslera teres em sementes de cevada cultivar BRS Elis com incid那ncia natural de 58%. Foram testados os fungicidas nas doses indicadas pela pesquisa de cevada (carboxina + tiram, difenoconazol e triadimenol) comparados com a mistura carbendazim + iprodiona. Como ve赤culos testou-se a 芍gua (500 mL/100 kg) e um pol赤mero (150 mL/100 kg). As sementes ap車s o tratamento foram armazenadas em sacos de papel e mantidas em refrigerador a 5oC. A intervalos de 30 dias, at谷 completar tr那s meses, as sementes foram plaqueadas em meio semi-seletivo de Reis (1983). O melhor controle foi obtido pelas misturas carboxina + tiram e carbendazim + iprodiona, com o ve赤culo pol赤mero. A efici那ncia do controle foi melhorada pelo tempo de armazenamento sem afetar negativamente a germina  o das sementes. Devido 角 efici那ncia de transmiss o a erradica  o do fungo em sementes deve ser perseguida.
