Abstract: A study was conducted at the Department of Plant Pathology, College of Agriculture, Vijayapur during 2014-15 to find out the efficacy of ten systemic fungicides viz. penconzole 10EC, tebuconazole 25.9EC, difenconazole 25EC, carbendazim 50WP, propiconazole 25EC, hexaconazole 5EC, thiophanate methyl 70WP, myclobutanil 10WP, azoxystrobin 23EC, tridemephon, two non systemic fungicides viz. cholothalonil 75WP, sulphur 80WP, chlorothalonil and three combip roducts Captan 70 %+ Hexaconazole 5% 75 % WP, Hexaconazole 4% + Zineb 68% WP under in vitro conditions against chickpea powdery mildew caused by Leveillula taurica. Among the systemic fungicides at 0.1 and 0.15 Per cent concentrations complete inhibition of conidial germination was in all the fungicides tested. But at 0.05 Per cent concentration complete inhibition of conidial germination was observed in myclobutanil and azoxystrobin and were significantly superior over other treatments. In all non systemic and combi products complete inhibition was observed at 0.2, 0.25 and 0.3 per cent concentrations.
