K. C. Deepthi

Abstract :

Stem rot caused my Sclerotium rolfsii sacc is one of the most important disease effecting groundnut crops all over world and in the Andhra Pradesh. A total of 40 antagonists were isolated from soil rhizosphere and root endophytes of the groundnut crop. When these isolates are subjected to in vitro studies and hence GRE-9 and GRB-4 has shown 100% inhibition of the mycelial growth against Sclerotium rolfsii. The efficacy of six fungicides viz., Carbendazim, Hexaconazole, Propiconazole, Thiophenate Methyl and COC and Mancozeb. When these fungicides were tested @ 0.1%, 0.2% and resulted that Mancozeb & propiconazole were found 100% effective in checking the growth of the pathogen while carbendazim was not effective against pathogen.
