Infection of detached leaflets of strawberry cv. Sonata by Phytophthora cactorum isolate RV4 with and without potential antagonistic bacterial isolates. Treatments from top to bottom rows: A: water only; B: P. cactorum; C: P. cactorum combined with bacterial isolate Pseudomonas fluorescens (number 6 from Clarias wastes); D: P. cactorum combined with bacterial isolate Pseudomonas veronii (number 4 isolated from Tilapia wastes). Wild type RV4 formed large disease lesions on treatment B. Treatment C, with isolate number 6, and treatment D with isolate number 4 exhibited no or minimal disease. Leaves were photographed four days after inoculation
