The impact of different treatments on population of two nematode species associated with guar (Cyamopsis tetragonoloba (L.) Taub.) and yield of guar was investigated. All the treatments namely Carbofuran, Fertinemakil Plus, plant extract of Tridax procumbens and leaf extract of Eucalyptus citriodora significantly decreased the populations of Rotylenchulus reniformis and Pratylenchus penetrans. ...

Twenty one O,O-diaryl O-ethyl phosphorothionates having different sustituents in the phenyl ring were tested in vitro for nematicidal activity against root-knot nematode, Meloidogyne incognita. Out of these, eight which showed good activity, were evaluated under glass house conditions on cowpea. These compounds had considerably increased the plant growth characters and significantly reduced th ...

Laboratory experiment revealed that high percentage of juvenile mortality occurred during all the exposure periods of all treatments especially after 72 hrs Data also showed that the treatments of both orange oil and Spirulina platensis had a significant effect on juvenile mortality especially at the highest concentration (86.6% and 78.4%) respectively. While, Origanum majorana showed the lowe ...
