Management of tip over disease of banana by using effective PGPRs and different chemicals

Abstract

Banana is one of the most versatile plant that can be used to heal various kinds of illnesses in every aspect. However, its cultivation is hampered by many diseases like in other crops. The least known soft rot disease among farmers caused by Erwinia carotovora subsp. carotovora has became a threat to banana cultivation. The present study was aimed to identify suitable control measures of soft rot to avoid the plunging of banana yield. A field experiment was conducted during 2019 imposing seven different treatments. Among the treatments no disease incidence was recorded streptocycline (500 ppm) + COC (3000 ppm) and K-cycline (500 ppm) + COC (3000 ppm). But the influence on plant height (49.40 cm), pseudostem girth (20.50 cm), number of leaves per plant (13.08) and number of scorched leaves per plant (0.87) were comparatively less in streptocycline (500 ppm) + COC (3000 ppm) treatment. Pseudomonas aeruginosa (B-8) + Bacillus cereus (B-13) treatment recorded highest plant height (52.00 cm), pseudostem girth (21.57 cm), number of leaves per plant (13.27) and number of scorched leaves per plant (3.17). Pseudomonas aeruginosa (B-8) also significantly influenced the growth promotion followed by Bacillus cereus (B-13). Whereas, untreated control was recorded with highest disease incidence and lowest growth parameters.
