Resumo: | Resistance induction is an alternative method to reduce pesticide use in plant disease control. We conducted experiments with four corn hybrids over two consecutive years (2011 and 2012) in order to test resistance in second-season corn treated with acibenzolar-S-methyl (ASM) or phosphorylated mannanoligosaccharide (MOS). In addition, the plants were subjected to a fungicide (azoxystrobin + cyproconazole) or a control treatment using water only. Distinct pathogens were found in the harvests from both years, but the MOS treatment resulted in hypersensitive response during both years. None of the products applied affected plant height, ear insertion height, or damaged kernel percentage. MOS resulted in higher hypersensitive response intensity, without reducing productivity, compared to the water treatment. The application of ASM did not induce a hypersensitive response. |

A indução de resistência se apresenta como um método alternativo para reduzir o uso de agrotóxicos no controle de doenças de plantas. Com o objetivo de verificar a indução de resistência na segunda safra de milho pelos indutores acibenzolar-S-metil (ASM) e mananoligossacarídeo fosforilado (MOS), experimentos foram conduzidos com quatro híbridos de milho em dois anos consecutivos (2011 e 2012). Além dos indutores de resistência, um fungicida (azoxistrobina + ciproconazole) foi aplicado, bem como pulverização com água como tratamento adicional. Foi observada incidência de patógenos distintos nos dois anos, embora o tratamento com MOS tenha resultado em resposta de hipersensibilidade em ambos os anos. Nenhum dos produtos aplicados afetou a altura de planta, altura de inserção da espiga e porcentagem de grãos ardidos. MOS aumenta a intensidade da resposta de hipersensibilidade, sem redução da produtividade em relação ao tratamento com água. A aplicação de ASM não induz resposta de hipersensibilidade.
