ABSTRACT

Three botanical formulations based on neem oil and Pongamia oil viz., No 60 EC(C) No 60 EC (A) and NOPO 60EC (C) were tried against root knot nematode Meloidogyne incognita on tomato, chilli and brinjal. The formulations were tried as seed treatment and seedling root dip @ 2ml / lit. All the three formulations were found superior to control. Among the formulations No 60 EC (C) was significantly superior to the other two formulations in the reduction of nematode population 48.6, 51.7 and 39.6 per cent over control on tomato, chilli and brinjal respectively. The yield increase over control in the crops were 52.6, 47.3 and 41.7 per cent respectively. The treatment has recorded the least root knot indices of 2.0 in the three crops tested as against 5.0 in the untreated control. Use of botanical formulation is easy to apply is of low cost and it is an environmentally safer method of nematode management.
