Abstract  

Field experiments were conducted at Regional Research Station, Paiyur, India during January 2012 - July 2014 to assess the efficacy of the TNAU talc and liquid commercial formulations of the native bio agents Pseudomonas fluorescens (Pf) and Trichoderma viridi, as turmeric rhizome treatment, soil application, foliar spray and in combination so as to develop nematode centric ipm and to standardize the management practices for nematode disease complex in turmeric. IPM module viz., turmeric rhizome treatment with talc formulations of Pf @ 10 g/kg seed rhizome plus soil application of Pf @ 2.5 Kg/ha along with 50 kg of well decomposed FYM plus Pf foliar spray application @ 2 lit/ha at three months interval recorded higher germination of 94.90 per cent, least injury causing nematode population of 223.0/250 g of soil at two months after sowing, 250.3 numbers/250 g of soil at termination, 32.3 endoparasitic nematodes/10 grams of root sample, 18.47 egg mass/10 g root, 177.40 eggs/egg mass, lower Gall index of 1.87 with 16,638 kg of wet turmeric rhizome/ha and found to be the best treatment followed by standard check viz., Carbofuran 3G @ 1 kg a.i/ha, 2 rounds at 3rd and 5th month after planting and drenching with copper oxy chloride 0.25%. The bioinoculants treatments have higher BC ratio when compared to standard chemical check treatment.
