ABSTRACT
Stem rot of groundnut caused by Sclerotium rolfsii Sacc. has a major constraint and potential threat to successful groundnut cultivation. Therefore affords were made to screen the different systemic, contact and combination of fungicides and herbicides in vitro condition against Sclerotium rolfsii. Among systemic fungicides, Propiconazole and Tricyclazole were found 100 % growth inhibitions at all concentrations. Thiophanate methyl was found least effective at 500ppm with growth inhibition of 48.51% . While carbendazim was least effective in growth inhibition of S. rolfsii at all tested concentrations. Among non systemic fungicides, mancozeb and Thiram were found 100 % growth inhibition of S. rolfsii at all concentrations. In combination of fungicides Carbendazim 12%WP + mancozeb 63% WP minimum growth inhibition was recorded at 500ppm(47.40%) followed by 1000ppm(87.03%). Out of three herbicides tested, Pendimethalin and Quizalofop p-ethyl showed hundred per cent inhibition of the pathogen. While in 2,4-D Na salt 65.6% growth inhibition of S. rolfsii was observed.
Key words: Fungicides, Herbicides, Stem Rot.
