Abstract/Description: | In India, Colletotrichum gloeosporioides cause anthracnose disease of many horticultural crops, including grapes. Carbendazim resistance in the pathogen is commonly observed. Eighty-seven endophytic bacteria were isolated from mature shoots of Thompson Seedless variety located at ICAR-National Research Centre for Grapes, Pune and screened for their antagonistic activity. Ten bacteria inhibited the radial growth of cabendazim resistant C. gloeosporioides isolates by 77.59 - 84.59 per cent in dual culture assay. Four of these bacteria completely prevented anthracnose infections in detached leaf bio-assay and were subsequently evaluated at 10 to the power of 4, 10 to the power of 5, 10 to the power of 6 CFU/ml on field grown vines. Vines treated with bacteria TS-31, TS-45 and TS-46 recorded low disease severity even at the lowest concentration of 10 to the power of 4 CFU/ml and area under disease progress curve (AUDPC) were 456.31, 355.31 and 446.25, respectively; while in fungicide control and untreated control AUDPC was 435.19 and 756.88. In detached berries, TS-45 showed almost complete control of berry infection (2.384.12%), while TS-46 (20.393.33) and TS-31 (35.4632.65) were less effective. These three promising bio-control bacteria were identified as Bacillus anyloliquefaciens based on morphological, biochemical and molecular characterization. |
