Isolation of Diaporthe phaseolorum var. caulivora from Abutilon theophrasti in Croatia

During 2000– 03 a weed survey was carried out in fields of soybean, sunflower and sugar beet in Croatia. Abutilon theophrasti (velvetleaf), found in soybean fields, showed symptoms of black lesions, several centimetres in length, on the stems and side branches. A fungus was isolated from stem lesions on potato dextrose agar (PDA) and incubated at 25°C, with a 12 h dark/light regime. Based on the morphological characteristics, the pathogen was identified as Diaporthe phaseolorum var. caulivora. To confirm pathogen identification, molecular analysis was performed. Comparison of the ITS sequences available on the database revealed that it was almost identical, with only two deletions in positions 24 and 542, to D. phaseolorum var. caulivora (AJ312360). Each year in Croatia the presence of fungi in the Diaporthe/Phomopsis complex can be observed on soybean, but these fungi do not appear to cause great economic damage under local conditions. This is, however, the first report of A. theophrasti as a host for D. phaseolorum var. caulivora in Croatia.
