Sažetak
The last several year area under soybean in Republic of Croatia constantly increase. By that, optimal crop rotation is decreased and rises incidence of different diseases of this very important file crop. This impose needs of the constant detection, identification and study of disease causal agent as well as the method of their control. Soybean (Glycine max (L.) Merr.) Diaporthe/Phomopsis complex can cause a several diseases and the three most important are: pod and stem blight, caused by Diaporthe phaseolorum (anamorph Phomopsis phaseoli) ; northern stem canker, caused by Diaporthe caulivora ; and Phomopsis seed decay, caused by Diaporthe longicolla. Southern stem canker is caused by Diaporthe aspalanthi, but this disease is still unknown in Europe. These fungi can also be involved in the root rot complex of soybeans and cause damping-off of seedlings. Beside soybeans, these pathogens could parasite numerous hosts, and some of them can cause serious economic damages in soybean production which can vary depending on climatic conditions particularly during harvest. The greatest losses usually are associated with seed decay. When wet weather delays normal harvesting, reductions of 10% in seed weight and 50% or more in seed germination are found in susceptible cultivars. Seeds infected with the fungi of this complex produce low-quality oil and flour and other value-added products, and are often unsuitable for vegetable or other food and feed uses. The aim of this work was to determinate the difference in pathogenicity among isolates of new species Diaporthe novem as well as the level of pathogenicity among these isolates in comparison to isolate of D. longicolla (causal agent of Soybean Seed Decay), which high aggressiveness was determinate in some previous investigation.
