| Abstract: | In order to study the biocontrol potential of strain L14-3 against phytophthora blight of pepper,the antifungal activity of strain L14-3 against Phytophthora capsici were detected by in vitro and pot experiments.The results showed that,in vitro experiment,L14-3 was significant inhibit the mycelial growth,zoosporangium production,release and germination of zoospore of P.capsici.In the pot experiment,L14-3 performed the successful potential control against Phytophthora blight of pepper,the control efficiencies was 75.00%.In addition,based on the morphological,physiological characteristics and 16S rDNA sequence analysis,the strain L14-3 was identified as Paenibacillus polymyxa. |
