| Abstract: | Leaf mold symptoms were found on tomato varieties carrying the Cf-9 resistance gene against Passalora fulva, the causal agent of leaf mold, in Japan in 2008. Disease symptoms and morphological characteristics of the isolates were
similar to those of P. fulva. After inoculating a set of tomato differentials with the isolates, all isolates were identified as race 2.9 of P. fulva, previously unreported. |
