“…The LC 50 of tuba root, citronella and pyrethrum were not reached, but their LC 20 was 5.7 -8.9 mg ml -1 exposure medium. The remaining 10 extracts were not toxic to the nematode as the LC 20 was not reached (> 19.2 mg ml -1 exposure medium) ( Table 2). Representative dose response graphs of extracts from each of these groups of plant extracts are given in Fig.…”

“…(1). The synthetic pesticides chlorpyrifos and carbosulfan both fell in the slightly toxic group with an LC 50 >19.2 mg ml -1 exposure medium and an LC 20 .of 8.7-12.7 mg ml -1 exposure medium. Deltamethrin fell into the non-toxic groups with a LC 20 > 19.2 mg ml -1 .…”

“…The corrected mortality (P T ) was plotted against the pesticide concentration and fitted using Slide Write Plus 6.1 (Advanced Graphics Software Inc.) to determine the LC 20 , LC 50 and LC 90 values. Because the log scale was used for plotting the data, the control data were included as a concentration being 100x lower than the lowest test compound concentration.…”

“…In order to make a comparison between botanical and synthetic nematicides, lethal concentrations i.e. LC 20 , LC 50 and LC 90 , were expressed as mg applied extract or technical mixture ml -1 exposure medium because the nature and concentration of the active ingredients of the botanical extracts are unknown.…”

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.

Sixty crude cultural filtrates of thirty fresh water fungi individually grown in both Potato Dextrose broth and GPC broth were assayed in vitro for antinematodal activity against Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle using immersion test. Filtrates from Camposporium quercicola YMF1.01300, Periconia digitata YMF1.00948, Caryospora callicarpa YMF1.01026 grown in both PDB and GPC broth, and the cultural filtrate of Melanospora zamiae YMF1.00948 grown in PDB were found to be pathogenic to the tested nematodes. The degree of activity varied with the fungal species, length of exposure time, and media composition. From a nematicidal cultural extract of Caryospora callicarpa YMF1.01026, four known naphthalenones were isolated and identified as 4,8-dihydroxy-3,4-dihydronaphthalen-1(2H)-one (1), 4,6-dihydroxy -3,4-dihydronaphthalen-1(2H)-one (2), 4,6,8-trihydroxy-3,4-dihydronaphthalen-1(2H)-one) (3), 3,4,6,8-tetrahydroxy-3,4-dihydronaphthalen-1(2H)-one (cis-4-hydroxyscytalone) (4) by NMR and MS analysis. All four metabolites showed noticeable biological activity against B. xylophilus nematode. This is the first published report of these compounds affecting plant-parasitic nematodes.
