Abstract

Studies on the effect of Purpureocillium lilacinum, Glomus fasciculatum, Trichoderma harzianum, vermicompost and carbofuran 3G in the management of Tylenchulus semipenetrans on Khasi mandarin under pot condition showed that all thetreatments were effective in increasing plant growth parameters of Khasi mandarin. All the treatments significantly decreased the final nematode population in soil and root over control. The treatment with vermicompost @ 15g/plant+ T. harzianum 10g/plant was found to be most effective in plant growth parameters of Khasi mandarin. The treatment with carbofuran 3G@ 4g/plant was found to be best in suppressing the final nematode population in soil and root followed by the treatment with G. fasciculatum@ 150spores/plant + P. lilacinus@10g/plant.
