| Abstract | ABSTRACT The research explorations entitled ‘Management of root knot nematode (Meloidogyne incognita Kofoid & White) in Chilli (Capsicum annuum L.)’ was conducted to explore the possibilities of nematode management in highly susceptible chilli crop by using different nematode management practices. In India, several species of Meloidogyne are reported on a variety of vegetables, cereals, pulses and ornamental plants. Root-knot nematode is a matter of great concern because this affects several economically important crop plants. Chilli is very important crop from the point of nutrition and health. In the present study, twelve treatments viz., bare root dip treatment with carbosulfan @ 0.05 per cent, neem cake @ 50 g/m2, mustard cake @ 50 g/m2, carbofuran 3 G @ 10 g/m2, neem cake @ 25 g/m2 + carbofuran 3 G @ 3.5 g/m2, mustard cake @ 25 g/m2 + carbofuran 3 G @ 3.5 g/m2, drenching with Econeem 5 ml/l of water, bare root dip treatment with carbosulfan @ 0.05 per cent + Econeem 5 ml/l of water, bare root dip treatment with carbosulfan @ 0.05 per cent + marigold intercropping, neem cake @ 25 g/m2 + P. lilacinum @ 50 g/m2, P. lilacinum @ 50 g/m2 and control were evaluated for their effect against M. incognita. Among all the treatment combinations, neem cake @ 50 g/m2 + carbofuran 3G @ 10 g/m2 application in the pots as well as in the field was most effective in reducing nematode population as well as increasing the plant growth and yield. This treatment was observed to be significantly similar to the yields of plots receiving carbofuran 3G @ 10 g/m2 and combination of mustard cake @ 50 g/m2 + carbofuran 3G @ 10 g/m2. The plots that did not receive any treatments, suffered maximum losses in terms of yield as well as plant vigour. It can be concluded from the study that the carbofuran is quite effective in reducing M. incognita population and root gall index in chilli. However, its effect can be enhanced by adding neem or mustard cake that accelerates the plant growth parameters. |
