Recent research has demonstrated an important interaction between Thielaviopsis basicola, the cause of black root rot, and the root-knot nematode, Meloidogyne incognita (Walker et al., 1998; 1999; 2000). This interaction causes dramatic reductions in early-season growth in producers’ fields and yield reductions of 21 to 44% have been documented in microplot and field research. The interaction i...

efficiency of pleurotus ostreatus and p. sajor-caju as biocontrol agents of the root knot nematode, meloidogyne javanica, was evaluated in vitro and in greenhouse experiments. population of the nematode were prepared and nematicidal effects of culture filtrates of the fungal specieson second stage juveniles of m. javanica were tested. substrates completely colonized by tested fungi as fungal in...

Management of Meloidogyne incognita (root-knot nematode) in cotton in the United States was substantially affected by the decision to stop production of aldicarb by its principle manufacturer in 2011. The remaining commercially available tools to manage M. incognita included soil fumigation, nematicide seed treatments, postemergence nematicide application, and cultivars partially resistant to M...

Meloidogyne enterolobii is widely considered to be an aggressive root-knot nematode species that is able to reproduce on root-knot nematode-resistant tomato and pepper cultivars. In greenhouse experiments, M. enterolobii isolates 1 and 2 from Switzerland were able to reproduce on tomato cultivars carrying the Mi-1 resistance gene as well as an N-carrying pepper cultivar. Reproduction factors (R...

biological control of root-knot nematode meloidogyne javanica by application of pseudomonas fluorescens cha0 was evaluated under greenhouse condition. results showed that p. fluorescens (109 cfuml-1) as shoot spray significantly reduced in no. of eggmass and egg per individual eggmass as comparison to control. application p. fluorescens as shoot spray induced systemic activation of peroxidase (...

This study was conducted to identification and distribution Root-knot nematode species in lavender fields where Lavandin (Lavandula × intermedia Emeric ex Loisel. var. Super) cultivated an area of about 625 ha Isparta Burdur Provinces Turkey. A total 60 samples were collected autumn 2020. Root knot molecular determined by species-specific primers from egg masses. The 17 taken found be infected ...

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...

A full-length cDNA, MIC-3, has been identified from a lambda ZAPII cDNA library constructed from the mRNA of nematode-resistant cotton (Gossypium hirsutum L.) roots after infection with root-knot nematode (Meloidogyne incognita). The putative open reading frame of MIC-3 encoded a protein of 141 amino acids with a calculated molecular mass of 15.3 kDa. Seven alternative polyadenylation sites hav...
