Alternaria alternata se identifico como el agente causal de la vaina negra y la decoloracion grisacea de la testa del frijol blanco. La severidad de la decoloracion de la vaina vario de manchas o puntos grises oscuros a parches grises oscuros los cuales despues se unieron. Las semillas de vainas severamente afectadas a menudo mostraron varios grados de decoloracion, los cuales persistieron durante el procesamiento. Las aspersiones de benomil y clorotalonil, utilizadas para el control del moho blanco (Sclerotinia sclerotiorum), incrementaron significativamente la incidencia de la decoloracion. In vitro A. alternata fue insensible a ambos fungicidas. Se presentaron con mas severidad la enfermedad de la vaina negra y decoloracion de la testa en el cv. Seafarer de maduracion temprana que en el cv. Fleetwood de maduracion tardia. (RA-CIAT) spa
Alternaria alternata was identified as the cause of the black pod disease and greyish discoloration of the seed coat of white beans. The severity of pod discoloration varied from dark grey flecks or stipples to dark grey patches which later coalesced. Seeds from severely affected pods often showed varying degrees of discoloration, which persisted through processing. Benomyl and chlorothalonil sprays, used to control white mold (Sclerotinia sclerotiorum), significantly increased the incidence of discoloration. In vitro, A. alternata was insensitive to both fungicides. There was more black pod disease and seed coat discoloration in the early-maturing cv. Seafarer, than in the late- maturing cv. Fleetwood.
