To evaluate the protective activity, leaves of potted ´Niagara´ (Vitis labrusca) vines were artifi cially inoculated with an urediniospore suspension of Phakopsora euvitis four, eight or forteen days after fungicidal spray; and to evaluate the curative and eradicative activities, leaves were sprayed with fungicides two, four or eight days after inoculation. Disease severity was assessed 14 days after each inoculation. All tested fungicides present excellent preventive activity against grapevine rust; however, tebuconazole and ciproconazole provide better curative activity than azoxystrobin and pyraclostrobin+metiram. It was observed also that all tested fungicides signifi cantly reduced the germination of urediniospore produced on sprayed leaves.  aGrapes  aDoença  aFungicida  aUva  aVitis Vinifera  aDisease  aFerrugem da videira  aPhakopsora euvitis1 aBUFFARA, C.
