| Abstract/Description: | Fresh leaves of Abutilon indicum, Azadiracltta indica, Calotropisprocera, Cassia auriculata, Crotalaria juncea, Datura stramonium, Prosopis juliflora, Tridaxprocumbens, Vitex rtegundo and Xanthium indicum were dried and the prepared extracts were tested against the root-lesion nematode, Pratylenchus coffeae infesting banana. In the preliminary study almost all the plant species exhibited nematicidal activity ranging from 20.7 to 96.5 per cent mortality at 24 hr exposure period. The best 3 plant extracts viz. A. indica, C. juncea and V. negundo were further diluted at 20, 40,60 and 80 per cent concentration and tested. A. indica exerted 73.4 per cent mortality of P. coffeae when exposed to 20 hr in the 80 per cent concentration of leaf extract followed by 76.4 and 64.8 per cent mortality with respect to V. negundo and C. juncea. No mortality was recorded in distilled water. |
| Description: | The root-lesion nematode, Pratylenchus cofJeae (Zimm.) Goodey is an important root parasite on banana and is widely distributed through the infested corm in South India, Gujarat, Oris sa, Bihar and Assam(Rajendranetal., 1979; Sundararaju, 1996). The infestation results in 25.3 per cent loss in yield (Sundararaju et al., 1999). Although considerable research work has been carried out on the management using different chemical nematicides, there is a very little work with reference to plant products havingnematicidallnematostatic properties as a possible measure for the management of the nematode problem. Sincenematicides are expensive and cause serious environmental pollution, control strategies are now directed towards the use of natural products. Green and dry manuring of plant parts have been practiced 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 betel and Moringa oleifera are reported to be lethal to Radopholus similis (Jasy & Koshy, 1992). Hence, an attempt was made to study the effect of certain plant extracts on P. cofJeae under in vitro conditions. |
