Manila: IRRIc1986  ap. 383-392.  aRice blast (Pyricularia oryzae Cav.) is a limiting factor for upland rice production in Brazil. Efforts at the National Research Centre for Rice and Beans (CNPAF/EMBRAPA) have focused attention on developing integrated disease control for upland rice in the region that is dominated by savanavegetation known as cerrado, Sensu lato. Cerrado vegetation covers about 1.8 million ha, mainly in central Brazil. Annual rainfall varies from 1,000to 1,700 mm, more than 90%of it occurring during the wet season, fromOctober to April.  aArroz  aBrusone  aCerrado  aDoença  aFungo  aManejo  aOryza Sativa  aPyricularia Oryzae  aArroz de sequeiro  aBlast1 aMORAIS, O.
