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

Objetivou-se avaliar o efeito de produtos químicos no seu controle e na produtividade de grãos de milho. O delineamento experimental foi em blocos casualizados, em esquema fatorial 2 x 7, com três repetições. O primeiro fator foi constituído pelos híbridos de milho P30F53VYHR (mais resistente à doença) e P4285VYHR (mais suscetível) e o segundo por seis ingredientes ativos (casugamicina, enxofre, óxido cuproso, oxicloreto de cobre, amônia quaternária e fosfito de potássio) e uma testemunha (sem aplicação). Os dados obtidos foram utilizados para estimar a área abaixo da curva de progresso da doença. Os produtos à base de amônia quaternária, óxido cuproso, oxicloreto de cobre e casugamicina proporcionaram maior controle da doença. P30F53VYHR apresentou produtividade de grãos superior à de P4285VYHR. Portanto, o uso de híbrido geneticamente resistente representa uma alternativa eficiente ao manejo dessa bacteriose.
