Studies were conducted to evaluate growth promotion and mildew (Phyllactinia corylea) suppressive effect of phylloplane bacteria of mulberry (Morus spp.) in vitro and in vivo and the effective bacteria were identified. Among 18 bacteria, 4 isolates showed highly significant (P<0.01) reduction with >70 per cent suppression of conidial germination. The highest reduction was showed by the isolate Pb-5 (13.87%) by suppressing 86.13 per cent conidial germination followed by Pb-4 (17.23%) with 82.17 per cent. Similarly, six isolates significantly increased the seed germination. Significantly high (P<0.01) seed germination was obtained (93.44%) with treatment of the isolate Pb- 6 followed by Pb-3 (86.22%), Pb-7 (86.22%) and Pb-4 (85.47%).Most effective bacterial isolates were identified as Bacillus megaterium (Pb-1) Bacillus subtilis (Pb-1) Bacillus cereus (Pb-1) and Pseudomonas aeruginosae (Pb-1). In vivo studies revealed highly significant (P<0.01) with >60% reduction of disease severity with the application of B.megaterium (63.42%) and B.cereus (60.73%). The study suggests exploration of either of these bacteria for biological control of mildew in mulberry.

Abstract


Studies were conducted to evaluate growth promotion and mildew (Phyllactinia corylea) suppressive effect of phylloplane bacteria of mulberry (Morus spp.) in vitro and in vivo and the effective bacteria were identified. Among 18 bacteria, 4 isolates showed highly significant (P<0.01) reduction with >70 per cent suppression of conidial germination. The highest reduction was showed by the isolate Pb-5 (13.87%) by suppressing 86.13 per cent conidial germination followed by Pb-4 (17.23%) with 82.17 per cent. Similarly, six isolates significantly increased the seed germination. Significantly high (P<0.01) seed germination was obtained (93.44%) with treatment of the isolate Pb- 6 followed by Pb-3 (86.22%), Pb-7 (86.22%) and Pb-4 (85.47%).Most effective bacterial isolates were identified as Bacillus megaterium (Pb-1) Bacillus subtilis (Pb-1) Bacillus cereus (Pb-1) and Pseudomonas aeruginosae (Pb-1). In vivo studies revealed highly significant (P<0.01) with >60% reduction of disease severity with the application of B.megaterium (63.42%) and B.cereus (60.73%). The study suggests exploration of either of these bacteria for biological control of mildew in mulberry.
