Bio-management of rice root-knot nematode (Meloidogyne graminicola)

Narasimhamurthy HB, Ravindra H, Mukesh Sehgal, Suresha D Ekabote and Ganapathi

The present field experiments was conducted to know the efficacy of bio agents viz., Paecilomyces lilacinus, Pseudomonas fluorescens, Pochonia chlamydosporia, Trichoderma harzianum, Bacillus subtilis, Consortium of bio-agents (Pseudomonas fluorescens + Trichoderma harzianum) and Carbofuran 3G @ 0.3 ai. alone for management of rice root-knot nematode Meloidogyne graminicola during Kharif-2015 at College of Agriculture, Shivamogga (Latitude: 13° 27’-14° 39’ N, Langitude: 74° 37’-75° 52’ E). The results revealed that all the treatments were significantly superior over check with respect to growth parameters and nematode population. However, the treatment combination of P. fluorescens @20g/m² + T. harzianum @ 20g/m² was found to be the best treatment as it recorded highest plant height (83.33 cm), root length (21.27 cm), maximum grain yield (45.60 q/ha) with least RKI (1.20) and least nematode population (185.44/200g soil) with reduction of 72.77% nematode population followed by Carbofuran 3G @ 0.3 ai /m2, T. harzianum @ 20 g/m², P. fluorescens @ 20 g/m² and B. subtilis @ 20 g/m² respectively.
