Biocontrolllng of bacterial stalk rot disease of maize [electronic resource].

Includes references.

Three biocontrol agents were used in this study against Erwinia carotovora var. Zea caused soft-rot disease of maize stalks. Three biocontrol agents revealed inhibitory effect against this pathogen. The biocontrol agent namely (Pseudomonas fluorescens, Streptomyces griseus and Azotobacter chroococcum showed different reduction in the pathogen growth rate in laboratory experiments. In green-house tests all bioagents were effective comparing with control. Application of bioagents as seed dressing and injection in the stalk of maize plants were used as suspension density of (7x1 0 cells per ml) to reduce soft-rot disease. This work aimed to study the effect of some of biocontrol agents against softrot disease caused by (E. carotovora var Ze8).
