Abstract:
An investigation was carried out on post-harvest diseases of banana and
evaluates the efficacy of some selected chemicals, botanicals and hot water
treatment against the pathogen. The experiment was conducted in in vitro
condition. In this study, the antifungal activity of six fungicides and hot water
treatment were tested under in-vitro condition against C. gloeosporioides. The
results of present study showed that three fungicides (Tilt 250 EC, Autostin 50
WDG, Rovral 50 WP) at 500 and 1000 ppm concentrations significantly
checked the fungal growth. The lowest mycelial growth (1.10 cm) was found in
case of Tilt 250 EC at 1000 ppm concentration at six day after inoculation. The
lowest severity (2.50%) of banana was recorded in case of the same fungicide
at same concentration (1000 ppm) and the reduction of infection was (97.08%)
over control. On the other hand, hot water treatment of banana had significant
effect in controlling anthracnose of banana over control. The severity of the
disease gradually decreased with the increase of water temperature and came to
the minimum infection (4.25%) at 55
o
C temperature treated for 5 minutes.
Application of Tilt 250 EC (1000 ppm) and 55
0
C temperature for 5 minutes
proved effective in management of anthracnose diseases of banana.
