The pathogenecity test of R. solani isolates was done
against strawberry plants in cultures out of pot (Table 2).
All the isolates developed black root rot disease, causing
more than 70% of mortality in strawberry plants. The
isolates SR1 showed the highest root rot disease development,
causing 95.47% plant mortality followed by SR13,
SR7 and SR16, showing 86.63, 83.74 and 73.15% plant
mortality, respectively. Based on the present findings,
isolates SR1 was selected for further study
