Sintomatología

Los síntomas incluyen lesiones foliares de color marrón claro , de forma redonda a ovalada (0,5 a 2,0 mm de diámetro) con márgenes de color marrón rojizo, a menudo con halos cloróticos en el follaje medio a superior del canopeo en la etapa de cuaje (R2).

Los síntomas son simialres a la mancha ocular causada por Kabatiella zeae (Narita & Y. Hirats).
