Powdery mildew caused by Golovinomyces cichoracearum (DC) V.P Heluta Var. cichoracearum is one of the important diseases of sunflower causing yield losses to a considerable extent. Seven fungicides: Wettable sulphur 80wp@0.2%, triadimefon 25wp@0.1%, triadimorph 80EC@0.05%, difenconazole 25EC@0.05%, propiconazole 25EC@0.1%, carbendazim 50wp @0.1% and benomyl 50wp@0.1% were evaluated in Randomized Block design under field conditions. All the fungicides were sprayed twice with fifteen days interval against the disease. The experiment conducted for three consecutive years:2009-10 to 2011-12.Pooled analysis data revealed that among the fungicides tested propiconazole 25EC@0.1% recorded least per cent disease index (17.3%), highest yield (1134kg/ha) and net returns. It is at par with triadimefon 25wp @0.1% with regards to per cent disease index (21.3 %), but not with yield (1074 kg/ha). In control highest per cent disease index (79.6%) and lowest yield (763kg/ha) were recorded. The per cent disease index ranged from 23.2 to35.3% in rest of the treatments. From the experimental results obtained, Propiconazole 25EC@0.1% has been recommended to the farming communities for management of the disease.
