abstract
The potential of biocontrol agents to control root knot nematode Meloidogyne incognita was scrutinize under the in vitro studies. Treatments using culture free filtrates of Pseudomonas putida was recorded higher nematode egg hatching and juvenile mortality at the rate of 83.67% and 81.34%, respectively, compared to the control. Further studied the repellence of P. putida against M. incognita in gherkin was recorded by twin pot set-up, wherever the penetration of juveniles was decreases compared to un-inoculated control and supressed the production of egg masses. Hence, dual action of this bacteria could deliver better control management of nematode in gherkin.
