Pathogenicity of Colletotrichum atramentarium on some potato varieties

  • M. J. Thirumalachar
Article

Summary

Colletotrichum atramentarium is a potential yet elusive pathogen of potato. When the yellowing and wilting symptoms are reported in association with other fungi, its destructive nature is recognized. However when the only symptoms are the killing of stolons and reduction in yield, its presence is overlooked.

It would appear thatC. atramentarium might cause considerable reduction in yield if Colletotrichum-infected potato and tomato haulms remain in the soil and serve as an infection source.

The concealed damage that was caused by the killing of the stolons of Phulwa and Darjeeling Red Round varieties should be regarded as important enough to warrant consideration ofC. atramentarium as a potential potato pathogen.

Resumen

Colletotrichum atramentarium es un patógeno potencial y elusivo de la papa. Su capacidad destructiva es reconocida solamente cuando los síntomas de amarillamiento y marchitéz son asociados con otros hongos. Sin embargo, cuando los únicos síntomas aparentes son la muerte de los estolones y reducción en rendimiento, la presencia del hongo es desapersivida.

Parecería queC. atramentarium pudiera causar una reducción considerable en el rendimiento, si los ratrojos de la papa y del tomate infectados porColletotrichum quedan en el suelo, donde pueden servir como fuente de infección.

El daño discreto causado por la muerte de los estolones de las variedades Phulwa y Darjeeling Red Round es de suficiente importancia para considerar alC. atramentarium como un patógeno potencial de la papa.
