De acuerdo con investigaciones realizadas en Brazil,\u00a0el agente causal de la Mancha Blanca del ma\u00edz es un complejo microbiano, que incluye a la bacteria\u00a0Pantoea ananatis<\/a>\u00a0<\/em>\u00a0<\/em>(Paccola\u2010Meirelles et al., 2001<\/a>; Goncalves et al., 2013<\/a>; Mamede et al., 2018<\/a>)\u00a0<\/em>y al hongo\u00a0Phaeosphaeria maydis<\/em>.\u00a0Esta enfermedad se denomin\u00f3 previamente mancha foliar por Phaeosphaeria<\/em> spp (Carson 2001; Carson et al., 2005; Lopes et al., 2007; Moreira et al., 2009; Schuelter et al., 2003) debido a que el agente causal inicialmente se consider\u00f3 Phaeosphaeria maydis<\/em>, un hongo filamentoso detectado en las lesiones tard\u00edas de la hoja (Fantin, 1994). Sin embargo, otros estudios aislaron Pantoea ananatis<\/em>, una bacteria gram negativa, de las etapas iniciales de las lesiones foliares, que luego se confirm\u00f3 que es el agente causal del complejo de la Mancha Blanca del Ma\u00edz. Estos estudios a\u00fan deben validarse en Argentina.<\/p>\n","protected":false},"excerpt":{"rendered":"
