Fairy ring spot incited by Cladosporium echinulatum is an unexplored yet disastrous disease of carnation. Bacillus amyloliquefaciens (VB7) with 10 diverse antimicrobial peptide genes, effectively reduced fairy ring spot intensity to 6.44 (per cent disease index, PDI) and increased flower yield (196.61 Nos/m2) compared to control (PDI - 60.33; flower yield - 140.70 Nos/m2). Plants treated with tebuconazole (250 EC, emulsifiable concentrate) and alternated with mancozeb (75% WP, wettable powder) were much effective and reduced disease intensity up to 3.46 PDI. However, flower yield was comparatively lesser to the treatment of B. amyloliquefaciens (VB7). Results revealed that B. amyloliquefaciens out-performed fungicides in growth promotion.

Abstract


Fairy ring spot incited by Cladosporium echinulatum is an unexplored yet disastrous disease of carnation. Bacillus amyloliquefaciens (VB7) with 10 diverse antimicrobial peptide genes, effectively reduced fairy ring spot intensity to 6.44 (per cent disease index, PDI) and increased flower yield (196.61 Nos/m2) compared to control (PDI - 60.33; flower yield - 140.70 Nos/m2). Plants treated with tebuconazole (250 EC, emulsifiable concentrate) and alternated with mancozeb (75% WP, wettable powder) were much effective and reduced disease intensity up to 3.46 PDI. However, flower yield was comparatively lesser to the treatment of B. amyloliquefaciens (VB7). Results revealed that B. amyloliquefaciens out-performed fungicides in growth promotion.
