Sclerotium rolfsii Sacc. is known to be a serious pathogen on many crops of economic importance including cucurbits.Due proliferic growth and ability forming sclerotia, this the major constraint in successful cultivation cucumber.The present investigation was thus carried out evaluate potential nine different fungicides i.e. carbendazim, thiophenate methyl, vinclozoline, captan, copper oxychloride, mancozeb, hexaconazole, mycobutanil propiconazole at concentrations 10, 50, 100 150 ppm, inhibition S. rolfsii.The primary assessment made vitro screening its concentration whereby hexaconazole lowest (10 ppm) rendered most vital effect (P<0.0001) reduction followed by mycobutanil.No observed plates amended with when further increased.Similar traced an experiment conducted root trainer.The percent infected plant also provided same impact received toxic-assay experiment.Maximum seedlings protection cucumber achieved through seed application even (P<0.01);similarly, no mortality detected higher fungicide.Although our result directly claiming best but we propose use combination from groups order avoid resistance development against particular fungicide.A carbendazim hereby proposed for seedling rolfsii.
