Abstract
The present paper deals with the result of experiments on the effect of rhizosphere bacteria and actinomycetes on the damping-off of cucumber seedlings inoculated with Fusarium oxysporum f. cucumerinum.Fusarium oxysporum f. cucumerinum, (F 22), showed a strong pathogenicity to cucumber seedlings and caused typical damping-off, when inoculated in sterilized soil. Occurrence of post-emergence damping-off of the seedlings, however, was extensively delayed by concomitant inoculation of F 22 with rhizosphere bacteria and actinomycetes. The extent of delay was remarkable when Gram-negative bacteria were inoculated concomitantly with F 22. Occurrence of pre-emergence damping-off of seedlings was also delayed by the concomitant inoculation of F 22 with rhizosphere bacteria and actinomycetes, isolate A-C.These results suggested that occurrence pattern of pre-emergence damping-off and post-emergence damping-off in the field might be extensively influenced by the rhizosphere bacteria and actinomycetes.
