Integrated Management of Root Knot Disease Complex of Brinjal by Using Fungal Bioagent

Abstract

In systematic survey a disease complex was found whichcaused disease complex resulting in heavy damage of brinjalcrop caused by root knot nematode Meloidogyne incognita androot will fungus Fusarium oxysporum f. sp. lycopersici. Sevralsprophytic fungi were found associated with the rhizospheresoil viz. Trichoderma hazarium, Aspergillus terreus, A. fumigatus,A. niger, Cladosporium oxysporum, Penicillium oxalium,Aspergillus species which was not egg parasitic but exihibitedhigh toxicity (85-100%) to second stage juveniles (J 2 ), C.oxysporum parasitized the egg by 84% but in effective againstJ 2 , while the eggs and juveniles of M. incoginita get effectedby T. hazarium by 80% and 72% respectively. The soil isamendment of vasicular mycorrhiza by talc basedformulation of T. hazarium @8g Kg -1 (2×106 spore load) alongwith leaf powder (0.05% w/w) of Tinospora longifolia andvasicular arbuscular mycorrhiza (Glomus fasciculatum) @ 100chlamydospore per kg soil.
