Nematicidal activity of terpenoids

Journal of Environmental Science and Health, Part B, 2013
Thirty four phytoterpenoids were evaluated for their nematicidal effect using the model nematode Caenorhabditis elegans. Nematicidal activities of the tested compounds at concentrations of 50 μg/mL showed wide variation in their effects ranging from no effect, weak, moderate and strong effects.

Characterization of the Nematicidal Activity of Natural Honey

Journal of Agricultural and Food Chemistry, 2012
Antimicrobial activities of honey against bacteria and fungi are extensively reported in the scientific literature. However, its nematicidal potential has not been characterized so far. This study examined the effect of natural honey on model nematode Caenorhabditis elegans and analyzed the honey component(s) responsible for nematicidal activity ...

Nematicidal Activity of Chrysanthemum coronarium

European Journal of Plant Pathology, 2006
Organic amendments and green manure are potential alternatives to the harmful chemical control means currently used against plant-parasitic nematodes. In this work, Chrysanthemum coronarium was applied to the soil as a green manure to control the root-knot nematodes Meloidogyne incognita and M. javanica.

Nematicidal Activity of some Sri Lankan Plants

Natural Product Research, 2003
Nineteen solvent extracts from seven Sri Lankan plants were examined for nematicidal activity against the root knot nematode Meloidogyne incognita. Extracts of Allophyhu cobbe, Lepisanthes tetraphylla (Sapindaceae), Sarcococca zeylanica (Buxaceae) and Hedyotis lawsoniae (Rubiaceae) have shown significant nematicidal activity.

Nematicidal activity of Paecilomyces spp. and isolation of a novel active compound

The Journal of Microbiology, 2009
Many species of Paecilomyces are entomogenous fungi and several are efficacious toward nematodes. To study the potential of Paecilomyces species in controlling nematodes, fungal extracts of 40 Paecilomyces spp. were evaluated for their nematicidal activity against Bursaphelenchus xylophilus and Panagrellus redivivus.

Nematicidal activity of dimethyl 1-dodecanephosphonate

Experientia, 1983
Dimethyl 1-dodecanephosphonate has been shown in laboratory bioassays and greenhouse tests to be highly active against 2 species of nematodes. Other phosphonate esters showed little or no activity.

Chemical Constituents of Cordia latifolia and Their Nematicidal Activity

Chemistry & Biodiversity, 2011
AbstractFollowing nematicidal activity‐guided isolation studies on the fruits, bark, and leaves of Cordia latifolia, two new constituents, cordinoic acid (=11‐oxours‐12‐ene‐23,28‐dioic acid; 1) and cordicilin (=2‐{[(E)‐3‐(3,4‐dihydroxyphenyl)prop‐2‐enoyl]oxy}‐3‐[4‐hydroxy‐3‐(stearoyloxy)phenyl]propanoic acid; 2) were isolated from the stem and leaves ...

Antibacterial, Antifungal and Nematicidal Activities of Rare Earth Ions

Biological Trace Element Research, 2016
Despite the name, rare earth elements are relatively abundant in soil. Therefore, these elements might interact with biosphere during the history of life. In this study, we have examined the effect of rare earth ions on the growth of bacteria, fungi and soil nematode.

Nematicidal activity of Trigonella foenum‐ graecum L.

Phytotherapy Research, 2001
AbstractThe aqueous, methanol and chloroform extracts of Trigonella foenum‐graecum caused significant (p < 0.05) mortality of Meloidogyne javanica larvae. The methanol soluble fraction eluted from pure distilled water showed the highest (>92%) nematicidal activity compared with the fractions eluted from pure methanol and different ratios of ...

Improvement of chitinase Pachi with nematicidal activities by random mutagenesis

International Journal of Biological Macromolecules, 2017
Chitinase, an enzyme that can degrade the main compositions of insect intestine and cuticle, has been used in the bio-control field. Our previous work has reported the chitinase Pachi with nematicidal activity (Caenorhabditis elegans). In the present study, to improve the chitinolytic and nematicidal activities of Pachi, a random mutant library was ...
