J., Anandhakumar. | Zeller, Wolfgang
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 Raoultelfa terrigena (G-584), Bacillus amyloliquefaciens (G-V1) and Pseudomonas fluorescens (2R1-7) were selected fcir 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.
