Resumen
Theobjective of this study was to evaluate the effectiveness of foliar applicationof fungicides to control Phaeosphaerialeaf spot and consequently on the features of the maize crop productivity inthe crop year 2014/15. The experimental design was randomized blocks, in a 2x4factorial scheme, with two hybrids, three treatments + a control in fourreplications. The treatments were based on the following fungicides (g i.a L-1):epoxiconazole + pyraclostrobin (333 + 167); cyproconazole + picoxystrobin (80 +200); azoxystrobin + benzovinliflupyr (300 + 150), which were applied inBG7051H and BG7060HR hybrids with knapsack/ manual sprayer, pressurized with CO2in the phenological stage of culture V8, 70 days after seeding (70 DAS). Theexperimental plot had four rows spaced at 0.50 m and length of 10.0 m,resulting in a total area of 20 m2 and useful area of 8 m2,which held the white spot severity assessments, grain yield (kg ha-1)and thousand grain weight (g). Significant differences were observed for allfungicides compared to the control. The control alone had the highest severityindex compared to the other treatments. Regarding the thousand grain weight andproductivity (kg ha-1), the azoxystrobin + solatenol treatment wassuperior to the control and other treatments with fungicides, with a higherproduction of grain compared to the control.
