Koshy, P.K.Sundararaju, P.2014-07-112014-07-112007-02Indian Phytopathology 1983 v-36 i-3 p-469-472http://hdl.handle.net/123456789/4017Pathogenicity of the burrowing nematode, Radopholus similis, on arecanut seedlings was studied at five population levels (0, 10, 100, 1000 and 10,000 nematodes per plant), replicated five times, under pot conditions. In general, reduced plant growth and intensity of root lesions and rotting was directly proportional to increase in nematode population. Significant reduction was recorded in shoot and root length and weight, number of leaves and collar girth pf inoculated plants compared to uninoculated ones. The nematode appears to be an important potential pathogen of arecanut.enArticle
