Bacterial wilt is a major disease in solanaceaous plants caused by a bacteria called Ralstonia
solanacearum. It affects large verities of solanaceaous plants worldwide. With an aim to develop
effective antibacterial agent without any residual affect, the present study was conducted to
analyze the in-vitro antibacterial potential of Morinda citrifolia against two different isolates of
Ralstonia solanacearum. The Morinda citrifolia leaf and fruits were collected, dried and
extracted using acetone and chloroform. The antibacterial activity of the extracts was assayed by
using disc diffusion method. The results revealed that the average zone of inhibition of the leaf
extracts was more in the chloroform extract (24mm) than in the acetone extract (23.5mm).
However, no significant difference was observed with both the extracts. The fruit acetone extract
produced 16.5mm zone of inhibition while the fruit chloroform extract produced 16mm zone of
inhibition. The overall inhibitory activity of the leaf and fruit extracts against Ralstonia
solanacearum (RSN6) isolate showed that 58.82% of the antibiotics produced less inhibitory
activity than the fruit and leaf extracts. The inhibitory activity of leaf and fruit extracts against
Ralstonia solanacearum (RSN12) isolate showed that 70.59% of antibiotics produced less
inhibitory activity than the fruit and leaf extracts of Morinda citrifolia. The results revealed that
both the extracts have produced inhibitory activity against Ralstonia solanacearum and the same
could be used to extract antibacterial compounds. The potential of Morinda citrifolia extracts
was found much better than most of the antibiotics
