Biological aspects of Diaporthe phaseolorum var. sojae


In Romania, experiments were carried out to determine nutritional and physical factors in the development of  Diaporthe phaseolorum var. soj ae (EPPO A2 organism). ·

The fungus sporulated well on potato glucose agar medium as well as agarized fragments of soy bean stems and petioles, favourably at temperatures ranging between 20-28° C and pH values of 6-8. Polysaccharides and monosaccharides were most easily assimilated among the carbon source, as were amides and nitrates among the nitrogen sources.
