Temperature effects on Diaporthe phaseolorum var. caulivora
In the US, experiments were carried out to study the effects of different temperatures on production of perithecia and pycnidia by Diaporthe phaseolorum var. caulivora (EPPO A2 organism).
Pycnidia developed only on stems which were incubated at 20ø and 25ø C. The greatest number of perithecia developed on stems incubated at 25ø C.
