Management of citrus nematode, Tylenchulus semipenetrans in acid lime, Citrus aurantoifolia

Abstract

The field experiment was conducted for management of citrus nematode infesting acid lime with six treatments including an untreated control. All the treatments were found to be significantly superior over an untreated control in reducing nematode population, egg masses and number of females at intermediate and termination stage of the experiment. However, the treatment of fluopyram 400SC @ 1250 ml / ha was found to be most effective in reducing the nematode population (48.94 %), number of females (37.70 %) and number of egg masses (56.10 %) at an intermediate stage. The next effective treatment was application of bioagent with Purpureocillium lilacinum @ 20 kg / ha. At termination stage of experiment. Treatment of bioagent viz., Purpureocillium lilacinum @ 20 kg / ha was found to be highly effective. At termination, the chemical treatment was significantly inferior to the organic treatments.
