The present work was done with the object of finding a unique ar combined fungicide that control in a better way the "Mildiu" Plasmopara viticola of the grape Vitis vinifera. It was between May and August of 1,992 in the District of San Antonio de Cumbaza in the Región San Martín situated at 06º25' South Latitude, 76º25' West Longitude and 800 meters above the middle sea level. The settling of the experiment was done in a plantation established approximately 18 years ago . The experimental Design was the Complete Randomized Block with four repetions, 9 treatments and 1 witness. 6 fungicides applied in the following way were studied: 6 specific fungicides ( Copper sulfate + cal = Ti, in dosis of 4-4-100; Mancozeb T2, in dosis of 1.5 kg.P.C/Ha. ; Mancozeb 64 /. + Metalaxil 8% T3, in dosis of 2.5 kg.P.C/Ha; Copper Oxichloride = T4, in dosis of 3 kg.P.C/Ha.¡ Bitertanol =T5. in dosis of 1 lt.P.C/Ha.; Micronized sulphur = T6, in dosis of 3 kg .P.C/Ha; 3 combinations (Copper sulfate + cal micronized sulfur = T7, in dosis of 2-2-100 = 1.5 kg.P.C/Ha .; Bitertanol + micronized sulfur = T8, in dosis of 0.5 lt. + 1.5 kg .P .C/Ha. Mancozeb + micronized sulphur T9, in dosis of 0.75 + 1.5 kg.P.C/Ha .; and a witness T10; adding a total of 10 treatments. 4 applications were done to the 21, 28, 44 and 72 days after the pruning; in all t he applications were added foliar fertilizer and an adherent. To establish the control of the fungicide to the disease "Mildiu" were evaluated the percentage of leaves and ill bunches after each application, in the percentage og leaves and ill bunches after each application, in the harvest the number of fruits per bunch, weight of the per bunch treatment and production , with the production obtained the economic analysis was done, relating Cost - Benefic of each treatment . The best results about the control of the disease "Mildiu" in leaves, bunches and best production with the third treat ment (T3 = Mancozeb 64% + Metalaxil 8% or Ridomil) with a neat benefit of 6,133.67 dollars per hectarea.
