Management of northern root knot nematode, Meloidogyne hapla in carrot (Daucus carota L.) with fungal bioagents along with organic amendment

Continuous cultivation of carrot in the same piece of land leads to severe infestation of northern root knot nematode, Meloidogyne hapla. Two field experiments were conducted at the Nilgiris and Kodaikkanal to study the influence of fungal bioagents along with farm yard manure against northern root knot nematode, Meloidogyne hapla infesting carrot. Application of nematode egg parasitic fungi, Purpureocillium lilacinum as seed treatment @20g/kgof seed+soil application @2.5kg/ha along with soil application of Farm Yard Manure@12.5t/ha suppressed northern root knot nematode, Meloidogyne hapla by 23.1% and enhanced the carrot root yield by 33.6% compared to control.
