Abstract:
The root-knot nematode is particularly difficult to manage because of high susceptibility of all commercial cucumber cultivars. Synthetic pesticides still constitute an integral part of conventional agricultural systems, compared to pesticides of biological origin or bio-pesticides. But, their use is not yet that extensive and a conclusion cannot be drawn as far as their efficacy is concerned on a large scale. So, growers have conventionally relied on nematicides applications to control root knot nematode. The experiment was conducted, in which three nematicides; Basamid, Formalin, Triazophos with three different concentrations for each were examined for their efficacy in reducing gall severity and soil nematode population and improving growth of cucumber along with control and Carbofuran was used as treated check. This experiment was conducted in pots as well as in infested seed beds. Basamid @ 40 g/sqm was found to be most effective in management of root knot nematode followed by application of Formalin @ 3%. The roots of cucumber were healthy and growth parameters were increased in this treatment. Results of this study will provide guidance for improving nematicides efficiencies in soil against root-knot nematode.
