Presence of Cochliobolus carbonum in Germany
So far, five different races have been described in Cochliobolus carbonum (EPPO A2 quarantine pest), among which race 3 causes long and narrow lesions on maize inbred lines and hybrids. Race 3 has been described for the first time in 1973 in Pennsylvania (US) and is prevalent in the south-eastern US. It was also found in 1981 in Japan on maize and was later identified as a foliar pathogen of rice. Studies have been carried out on isolates from China (Shandong, Hebei - leaves collected respectively in 1990 and 1991), from Nigeria (in Ibadan in 1990) and from Germany (in Emmendingen in 1991). The pathogen has been identified as C. carbonum race 3. The EPPO Secretariat had previously no information on the occurrence of C. carbonum in Germany.
