Chemical control of nematodes in peanut crops

S. N. Mahapatra, N. N. Padhi

Abstract


Peanut (Arachis hypogaea L.) is subject to parasitisation by various species of plant parasitic nematodes. Usually field populations consist of several species (Ingram and Rodriguez-Kabana, 1980). During a preliminary survey, plant parasitic nematodes, Rotylenchulus reniformis Linford et Oliveira, Hoplolaimus indicus Sher, Pratylenchus zeae Graham and Helicotylenchus ahunaamai Siddiqi were isolated from the rhizosphere of peanut plants in central farm, O.U.A.T., Bhubaneswar. Three granular and three E.C. formulations of nematicides, singly and/or in combinations were tested with a view to find a suitable control measure against the nematodes occurring in peanut fields.
