Summary

After screening of several rhizosphere bacteria against the soilborne pathogens of
red core and crown rot disease of strawberry Phytophthora fragariae var. fragariae
and Phytophthora cactorum under in vitro conditions, three of the most active isolates
which produced up to 63% of reduction in mycelium growth, such as Raoultella
terrigena (G-584), Bacillus amyloliquefaciens (G-V1) and Pseudomonas fluorescens
(2R1-7) were selected for further studies under in vivo conditions. In a greenhouse
and field experiments, mentioned above three isolates were tested against both
Phytophthora diseases under artificial infested soil conditions. Root dip treatment
with these bacterial antagonists produced a control effect on both fungal diseases
between 27 to 55 % and were in some cases comparable with the chemical fungicide
Aliette.
