The increased concern for environmental and health hazards have called for a reduction in the use of synthetic nematicides for nematode control. Experiments were, therefore, conducted to ascertain the nematicidal potential of castor bean’s crude extract and its five lower concentrations with water as control. In the in vitro studies, crude castor bean aqueous extract and 10, 20, 30 and 40% diff...

systemic induction of peroxidase and polyphenoloxidase in tomato roots and stem followed by application of split root system method was investigated. root system of tomato seedling in the sixth growth stage were divided in two equal sections after washing and replanted in two adjacent pots and then inoculated with nematode and fungus as fallowing treatments. the second treatment was inoculation...

Nematode-suppressive soils are characterized by the ability of soil microbial communities to reduce populations plant-parasitic nematodes (PPN) either directly or inducing systemic resistance in plants. Various microorganisms have been recognized as antagonists PPN suppressive using culture-dependent and culture-independent methods. However, associations that form with nematode-conducive poorly...

Abstract Background Bacterial bioagents, Pseudomonas fluorescens , P. putida Bacillus amyloliquifaciens and B. megaterium have management potential against root-knot nematode (RKN), Meloidogyne incognita in bottle gourd. Results Field laboratory experiments were conducted to evaluate the effect of bacterial bioagents 1% WP (2 × 10 6 CFU/g), 8 9 CFU/g) on egg hatching juvenile mortality nematode...

to evaluate the effect of metarhizium anisopliae and trichoderma harzianum on root knot nematode (meloidogyne javanica) in tomato, experiments was performed under controlled as well as greenhouse conditions. volatile and non-volatile tests showed that there is no inhibitory effect against every one of each biocontrol agents. on the larval mortality and inhibition of egg hatching, a laboratory t...

The cystine knot three-dimensional structure is found in many extracellular molecules and is conserved among divergent species. The identification of proteins with a cystine knot structure is difficult by commonly used pairwise alignments because the sequence homology among these proteins is low. Taking advantage of complete genome sequences in diverse organisms, we used a complementary approac...
