Chemical products for corn bacterial streak control

ABSTRACT Xanthomonas vasicola pv. vasculorum is one of the main bacterial diseases in corn, which causes damage to crops due its fast dissemination and difficult control. This study aimed evaluate effects chemical products on control corn grain yield. The experimental design was randomized blocks, a 2 x 7 factorial arrangement, with three replications. first factor consisted hybrids P30F53VYHR (more resistant disease) P4285VYHR susceptible) second six active ingredients (kasugamycin, sulfur, cuprous oxide, copper oxychloride, quaternary ammonia potassium phosphite) (no application). obtained data were used estimate area under disease progress curve. based ammonia, oxychloride kasugamycin provided greater presented higher yield than that for P4285VYHR. Therefore, use genetically hybrid an efficient alternative management this bacteriosis.
