Summary
Foliage symptoms of bacterial ring rot of potatoes appear much earlier and are more severe at a soil temperature of 25 C than at 16, 19, 22, 28, 31, or 34 C. Percentages of tubers infected is about the same at temperatures between 16 and 28 C. In cold climates this could result in the spread of the disease without its detection in the field.
Resumen
Síntomas del follaje para pudrición de anillo bacterial de la papa (bacterial ring rot) aparecen mas pronto y son mas severos a 25 C que a 16, 19, 22, 28, 31, ó 34 C. Porcentajes de tubérculos infectados son casi los mismos a temperaturas entre 16 y 28 C. En climas frios ésto podría resultar en una dispersión no detectada de la enfermedad en el campo.
