| description | The leaf “frog-eye” spot is a disease that often occurs in Argentina and Brazil is becoming important in soy producing regions. The difficulty in achieving inoculum for studies with P. sojina led to the development of this work was to determine the sporulation of races P. sojina in different culture media and light regimes and check difference in sporulation of races of this fungus. The plates with the culture media BDA, STT , AI , V8 and FAA containing the three races of P. sojina were subjected to a photoperiod of 12/12 h (light and dark) and continuous dark. The experimental design was a factorial 5x2x3 (culture medium, light regimes, races of P. sojina) with four replications. The greatest number of conidia cm- 2 of the fungus was found for race 23 in the middle of STT culture and races 24 e 25 in the middle of V8 culture. The fungus race 25, with the largest number of conidia cm-2, regardless of the medium and the light regimen. With respect to light regime for all races of the fungus, the largest esporulation were checked at a photoperiod of 12/12 h. When the fungus was grown in culture medium AI, this had the largest area of the colony, regardless of breed fungus and light regime |
