Comparative efficacy of nematicides, oil cakes and plant extracts in the management of Meloidogyne incognita, Pratylenchus delattrei and Rotilenchulus reniformis on brinjal

Pot culture studies were conducted to find out the effect of nematicides (carbofuran, phenamiphos, phorate, margocide EC and nimbicidin EC), oil cakes (neem, castor, mahua) and plant extracts (Crotoloria juncea, Androyraphis paniculata, Medicogo media and Anona squamosa) on populations of Meloidogyne incognita, Pratylenchus delattrei and Rotylenchulus reniformis in brinjal cultivar Co. 2. Chemicals proved most effective in reducing the nematode population, phenamiphos 5G being the best followed by carbofuran 3G and phorate 10G. Oil cakes ranked next to chemicals. Plant extracts were least in their effect. Oilcakes boosted the growth of the plants and root weight was increased by chemicals.
