Evaluation of the effective integrated methods for the control of root knot nematode (Meloidogyne javanica) in tomato

Different nursery treatments alone and in combinations with spot application of aldicarb (Temik 5G) @ 1.0 kg a.i./ha and neem (Azadirachta indica) leaves @ 50 qts/ha in the field were evaluated for control of root-knot nematode (Meloidogyne javanica) infecting tomato (cv HS 101). Reduction of 48.9 and 26.7 per cent in nematode population was obtained in nursery treated with neem + spot application of aldicarb and nursery treated with neem + spot application of neem leaves respectively. Aldicarb treated nursery plus spot treatment with aldicarb at transplanting showed maximum reduction (62.3 per cent) in M. javanica population. However, use of uninfected tomato nursery + aldicarb treatment gave highest yield of 7.6 kg per plot (2.0 x 1.5 meters) in comparison to 4.7 kg in plots when infected tomato nursery was transplanted alone.
