“…Plants having nematicidal properties Plants are important sources of naturally occurring compounds having nematicidal properties, like alkaloids, diterpenes, fatty acids, glucosinolates, isothiocyanates, phenols, polyacetylenes, sesquiterpenes and thienyls (Chitwood, 2002). The ability of plant parts/ products to reduce crop damage caused by root knot nematodes, Meloidogyne spp., in amended soil is well documented (Begum et al, 2003;Jesse et al, 2006). Their ability, minimum toxicity to man and animal safety, safety to the environment and effectiveness in controlling the nematodes make plant parts indispensable to nematode control ( Jesse and Jada, 2004).…”

| Nematicidal activities of different plants viz., Amaranthus viridis, Chenopodium album, Solanum nigrum, Carica papaya and Euphorbia hirta have been evaluated against root-knot nematodes. Plants were collected from different areas of Karachi. Aqueous extracts (2, 6 and 10%) of these five plant species were made for the experiment. All selected plant species inhibited egg hatching and caused larval mortality. Maximum reduction (24.3%) in egg hatching was recorded in C. album stem extract at 2% concentration. The minimum reduction (0.33%) was observed in the leaf extract of A. viridis at 10% concentration after 48 hours of exposure time. In larval mortality test, maximum larval mortality (33%) was recorded in C. album leaf extract at 10% concentration while minimum larval mortality (0.66%) was noted in Solanum nigrum at 2% concentration in leaves and stem extracts after 72 hours of exposure time as compared to control.

Nematicidal activity of extracts from plants was assayed against Meloidogyne incognita. In laboratory assays extracts from tobacco (Nicotiana tabacum L), clove (Syzygium aromaticum L), betelvine (Piper betle L), and sweet flag (Acorus calamus L) were most effective in killing the nematode, with an EC 50 that was 5-10 times lower than the EC 50 of the synthetic pesticides chlorpyrifos, carbosulfan and deltamethrin. The shapes of the dead nematodes differed in a characteristic way, and groups of pesticides and plant extracts could clearly be distinguished based on this phenomenon, which may be an indicator for the modes of action of the tested pesticides. In a greenhouse bioassay clove bud and betelvine were tested as mulch. Experiments revealed that the total number of live nematodes on roots of pepper plants treated with mulch of the clove bud was 7% of that of the controls and did not differ significantly from that of plants treated with the recommended synthetic pesticide carbofuran. The application of clove buds as a botanical pesticide for future use against nematodes is highly promising since clove is the 6 th major plant grown on Bangka Island, and the market value of clove has decreased sharply over the last years.
