    Survey and Management of Root-knot Nematode Meloidogyne javanica) in Field Pea (Pisum sativum Var. arvens L.)
    (2022) Rajveer; Gurjar, Hemraj
    Present study was carried out in Rabi season 2021-22 in Division of Nematology at Rajasthan Agricultural Research Institute, Durgapura, Jaipur on survey and management of root-knot nematode (Meloidogyne javanica) in field pea (Pisum sativum Var. arvens L.). The distribution and occurrence of root-knot nematode in Zone IIIA of Rajasthan and the response of resistant promising cultivars against root-knot nematode, loss estimation caused by root-knot nematode and management of root-knot nematode, Meloidogyne javanica through newer nematicide in field pea. A survey was carried out during the months of January to February, 2022. During survey total 482 soil and root samples were collected from from 27 localities of Zone IIIA of Rajasthan included Jaipur, Ajmer, Dausa and Tonk districts. Out of 482 Meloidogyne spp. was found maximum in 453 samples with 93.98% absolute frequency, 22.31% absolute density and 2.16% prominence value. Out of 27 localities the 100 % incidence of root knot nematode was recorded in 16 locilities i.e., Sanjhariya, Fathehpura, Bobas, Begus, Baseri, Keshyawala, Dhankya, Nimeda, Mukundpura, Lalsot, Chak Toonga, Madhogarh, Beechha, Kanota, Harsuliya and Bassi.The other plant parasitic nematodes like Helicotylenchus spp., Pratylenchus spp., Hoplolaimus spp. and free-living Saprophytes also look into collected soil and root samples. In other pathological disease the maximum disease incidence of root-rot (Fusarium oxysporum f. sp. Pisi) disease of field pea was recorded in Diggi (ARSS) Institute (30.00%) of Tonk district and maximum disease incidence of wilt (Rhizoctonia solani) disease of field pea was recorded in Bassi village (25.00%) of jaipur district. In the varietal screening of forty two cultivars i.e., Adarsh, Aman, Ambika, HFP 1426, HFP 1428, HFP 529, HFP 715, HFP 9426, HFP 9907B, HFP-4, HUDP 15, IPF 16-13, IPF 20-17, IPF 20-21, IPFD 10-12, IPFD 1-10 (Prakash), IPFD 11-5, IPFD 12-2, IPFD 14-2, IPFD 19-1, IPFD 19-3, IPFD 20-2, IPFD 20-3, IPFD 20-8, IPFD 20-9, Pant P 243, Pant P 250, Pant P 42, Pant P 455, Pant P 462, Pant P 479, Pant P 480, Pant P 484, Pant P 497, Pant P 498, Pant P 501, Pant P 74, RFP 2010-4, RFPG 181, SKNP 04-09, TRCP 8 and TRCP 9 screened to detect the source of resistance against root-knot nematode, Meloidogyne javanica. Out of 42 sixteen cultivars sixteen i.e., Adarsh, Aman, HFP 1426, HFP 1428, HFP 715, HFP 9426, HUDP 15, IPF 16-13, IPFD 10-12, IPFD 11-5, IPFD 12-2, IPFD 19-1, Pant P 480, Pant P 484, Pant P 497 and Pant P 498 were found highly susceptible. Remaining twenty six cultivars i.e., Ambika, HFP 529, HFP 9907B, HFP-4, IPF 20-17, IPF 20-21, IPFD 1-10 (Prakash), IPFD 14-2, IPFD 19-3, IPFD 20-2, IPFD 20-3, IPFD 20-8, IPFD 20-9, Pant P 243, Pant P 250, Pant P 42, Pant P 455, Pant P 462, Pant P 479, Pant P 501, Pant P 74, RFP 2010-4, RFPG 181, SKNP 04-09, TRCP 8 and TRCP 9 were showed susceptible reaction against root-knot nematode, Meloidogyne javanica. No anyone was found highly resistant, resistant and moderately resistant against root-knot nematode, Meloidogyne javanica
