“…In an earlier report, Lang et al (2012) observed that the use of bio-organic fertilizer, composed of amino acid and manure composts with antagonistic B. subtilis HJ5 and DF14, changed the fungal community structure and reduced the population of Verticillium dahlia in cotton rhizospheres. The multivariate analysis of the community pattern of the DGGE profiles and dendrogram generated revealed distinct influences, especially those of biofilmed inoculants on the bacterial communities.…”

The suppressive effects of microbial inoculants on cotton seedling mortality were assessed in Rhizoctonia solani‐infested soil. Per cent mortality ranged from 16 to 32 (60–120 days after sowing, DAS) and significant differences were recorded at 120 DAS, especially after drenching with compost tea of Azotobacter sp. and Anabaena torulosa—Trichoderma viride‐biofilmed formulations. The activity of hydrolytic enzymes was reduced in diseased root tissues due to a majority of the microbially inoculated treatments, compared with healthy root tissues. Per cent changes in the amounts of glomalin‐related soil proteins (GRSPs) were 2 to 85% greater than those of the uninoculated experimental controls. These microbial inoculants altered the rhizosphere bacterial communities as evident from the Denaturing gradient gel electrophoresis (DGGE) banding patterns and, also reduced the population of R. solani. While the copy numbers of the internal transcribed spacer (ITS) gene of R. solani in the uninoculated (infested soil) were approximately 1.47 × 1011 per g soil, they were 1.34–1.42 × 105 per g soil after the application of A. torulosa, Anabaena laxa and A. torulosa–Bacillus sp. Increases in yield (ranging from 3 to 23%) due to various microbial inoculants relative to uninoculated controls illustrated their promise as plant growth‐promoting and disease‐suppressing agents. This study illustrates the modulation of rhizosphere ecology through microbial inoculants as a mechanism of disease suppression and sustaining plant growth.

“…Suppression of the bacterium was possibly driven by changes in the soil microbial community structure (Gorissen et al, 2004). Lang et al, 2012 reported that bio-organic fertilizer effectively reduced the disease incidence of cotton Verticillium wilt, and suppressed the growth of V. dahliae in soil. Similar results have also been observed by Termorshuizen et al (2006).…”
