Rust (Uromyces fabae) has increased in terms of frequency of disease severity, grain yield losses and per cent yield decrease in field pea (Pisum sativum) at the Crop Research Centre, of the university. During 2007-08 and 2008-09 crop seasons an experiment was conducted to assess the damage/yield loss caused by the disease. Rust was first observed in field on Ist week of February and by 23 March plants of all treatments were dead. One, two, three and four sprays of seven fungicides viz., propiconazole (tilt) (0.1%), bitertanol (baycor) (0.1%), triadimefon (calixin) (0.05%), mancozeb (indofil M-45) (0.25%), probineb (antracol) (0.1%), tebuconazole (folicur) (0.25%) and captafol (difolatan) (0.2%) were sprayed separately in each plot. Among all fungicides one, two, three and four times foliar spray (10 days interval) of propiconazole was found most effective against rust severity and grain yield followed by bitertanol and triadimefon
