Abstract

Background and aims
Co-inoculation of biocontrol agents with different modes of action is assumed to improve biocontrol activity. The present study aimed to investigate the effects of single or co-inoculation of Trichoderma viride strain GB7 and Serratia plymuthica strain 3Re4-18 on microbial communities in the rhizosphere of lettuce and their ability to suppress Rhizoctonia solani AG1-IB.
Methods
Growth chamber experiments with two different application modes were performed with single or co-inoculation of GB7 and 3Re4-18 in the presence or absence of R. solani. Biocontrol efficacy and plant growth parameters were assessed. Bacterial and fungal communities were analyzed by 16S rRNA gene and ITS fragments PCR-amplified from total community DNA of rhizosphere samples and analyzed by denaturing gradient gel electrophoresis …
