The arbuscular-mycorrhizal fungi (AMF) species used were Sclerocystis dussi, Glomus intraradices, G. fasciculatum, G. bagyaraji, G. leptotichum, G. monosporum, Gigaspora margarita, and a mixed AMF culture, were multiplied on maize roots. Forty five-day old maize plants were harvested for their roots. The extracted root sap was added into culture medium and was inoculated with pathogen. Owing to presence of root extract of mycorrhizal maize plants, inhibited growth of Dematophora necatrix was noted underin vitro conditions. Root extracts of all the AMF treated plants exhibited antagonistic activity with 44.8–73.6% inhibition after 5 days of inoculation against white root rot.
Antagonistic activity, Dematophora necatrix, Glomus spp, Malus domestica
