Bio-management of root knot nematode, Meloidogyne incognita in turmeric (Curcuma longa L.) under different irrigation systems

Abstract

The present field experiments conducted on turmeric (var: Local) under conventional and drip irrigation method to evaluate the efficacy of commercially available biocontrol agent of Pseudomonas fluorescens in talc and liquid formulation (bionemagation) during Aug to Dec’2014. Talc and liquid formulation (bionemagation) was applied at different dosage with different time of application and compared with untreated and standard check carbofuran 3G against root knot nematode, Meloidogyne incognita. The study results demonstrated using bioformulation was optimised as 2.5 kg/ha at 90 and 150 DAP under conventional method in respect to talc formulation. Similarly, the bionemagation with liquid formulation of P. fluorescens at 3 lit/ha at 90 and 150 DAP under drip irrigation for the effective management of root knot nematode and improve the rhizome yield with curcumin content in turmeric.
