During a screening for entomopathogenic bacteria in soil samples carried out. The use of copper is particularly hazardous during blooming, which is a phenological phase with a high risk of Psa infection. There has been an increased interest in biological control agents in last. However, the use of copper has some severe limitations because of environmental concerns, phytotoxicity and the possible development of bacterial resistance. In the case of Psa, the common preventive strategies rely on the use of copper formulations. actinidiae (Psa), the causal agent of kiwifruit bacterial canker.īiological control represents a promising strategy to reduce or complement the use of chemical pesticides. Biological control represents a promising strategy to reduce or complement the use of chemical. The present study aimed to isolate and characterize candidate biological control agents against Pseudomonas syringae pv. actinidiae (Psa), the causal agent of kiwifruit bacterial canker.

Among a collection of fluorescent pseudomonas isolated from the rhizosphere of pepper, twelve isolates were initially selected based on dual culture assay on potato dextrose agar and corn meal agar. capsici using different screening methods. Screening of microbial biocoenosis of Actinidia chinensis for the isolation of candidate biological control agents against Pseudomonas syringae pv. The aim of this study was to assess the potential of bacterial antagonists to control Phytophthora blight of pepper caused by P.
