Abstract

Field studies were conducted in 1998 and 1999 to investigate the effects of air-dried milled neem leaves, Siam weed leaves and roots each at 30kg/ha and 50kg/ha and carbofuran at 1.5kg a.i./ha and 2.5 kg a.i/ha on Meloidogyne incognita infecting cowpea cv. IT 86D- 715. Carbofuran-treated plants had the highest grain yield (1.7 t/ha), and the least root galling (0.6) at harvest while carbofuran – treated soil had the least nematode population after harvest and population of Pratylenchus spp was reduced by 83.2%, Helicotylenchus spp. by 86.5%, Xiphinema spp by 89.1% and Meloidogyne incognita by 94.8%. This was followed by the grain yield in neem leaf-treated plants (1.35 t/ha) with a root galling of 1.4, while nematode population in neem leaf-treated soil was reduced as follows: Pratylenchus spp., 67.6%, Helicotylenchus spp., 64.1%, Xiphinema spp., 64.8% and M. incognita, 83.4%. Grain yield in Siam weed –treated plants (0.8 t/ha) with a root galling of 1.7, was higher than that of control plants and population of Pratylenchus spp. was reduced by 49.9%, Helicotylenchus spp. by 59.1%, Xiphinema spp. by 63.2% and Meloidogyne incognita by 74.9%. Key Words: Meloidogyne; incognita; neem leaves; siam weed; leaves; siam weed roots; carbofuran Moor J. Agric. Res. Vol.4(1) 2003: 94-99
