Description The root-lesion nematode, Pratylenchus coffede causes
extensive root damage to banana which results in serious
economic losses. Because nematicides are very expensive,
control strategies are nowadays directed towards
the use of natura1 products. Manuring with green
and dry plant parts have been practised as a method for
the control of plant parasitic nematodes (Osman et al.,
1989). Leaf extracts of Glyricidia maculata, Ricinus communis,
Crotalaria juncea, Glycosmis pentaphylla,
Azadirachta indica, Kalanchoe pinnata, Piper betle and
Moringa oleifera have been reported to be lethal to
Radopholus similis (Tasy and Koshy, 1992). Intercropping
of banana with C. juncea was found to reduce R.
similis with irnproved growth and yield of banana in India
(Charles and Venkitesan, 1993). Significant yield increases
and reduction in P coffeae populations were also
recorded in banana plants treated with 50 per cent of N
applied by neem cake (Sundararaju and Kumar, 2000).
The present paper reports the result of a field experiment
undertaken to test the nematicidal efficacy of
leaves belonging to ten botanicals.
Dry and fresh leaves of ten locally available botanicals were tested against the root-lesion nematode, Pratylenchus coffeae in banana cvs Nendran and Rasthali under field conditions. All the botanicals were effective in reducing the nematode population and subsequently increased the plant growth characters and yield compared to untreated control. Among the different botanicals tried, application of Azadirachta indica, Calotropis procera, Datura stramonium, Crotolaria juncea and Vitex negundo were found to be superior and effective in reducing the nematode population and increasing the yield significantly.
