The first occurrence of leaf mold of tomato caused by races 4.9 and 4.9.11 of Passalora fulva (syn. Fulvia fulva) in Japan

2009

Tomato leaf mold caused by Passalora fulva was found on two tomato varieties carrying the Cf-9 gene in Japan, in 2007. The isolates obtained from Chiba and Fukushima were identified as race 4.9.11, and those from Gunma were races 4.9 or 4.9.11. This is the first report in Japan of tomato leaf mold caused by P. fulva strains that can overcome the Cf-9 gene.
