Isolates of P. p. nicotianae pathogenic to tobacco were weakly pathogenic on C. roseus and variable in their biocontrol of damping-off. Rice grain cultures of P. parasitica (14-21 days old) at 0.05 g per 25.4 cm 2 plug tray were optimal for screening potential biocontrol isolates in the greenhouse. After screening 41 isolates in preliminary experiments, 11 isolates were tested in three repeated experiments. Three isolates of P. p. nicotianae (402, 602, and 723) that represented the range of effective control of P. parasitica were chosen for further study}, number={2}, journal={PLANT DISEASE}, author={HOLMES, KA and BENSON, DM}, year={1994}, month={Feb}, pages={193–199} }
