Abstract:
Based on the routine morphological and biochemical detection methods,and combined with 16S rRNA gene sequence analysis and phylogenetic tree identification,a bacterial biocontrol strain was identified as Paenibacillus polymyxa,named KC24.The biological control effect of its fermentation broth was tested on rust.The results showed that the control effect of Paenibacillus polymyxa strain KC24 against Begonia rust was 52.1%,which was equivalent to the control effect of myclobutanil 25% EC (4 000 times).Paenibacillus polymyxa strain KC24 was suitable for bio-controlling begonia rust.
