Abstract: Diseases are major constraints to pea production in the developing countries. Among various diseases, the rust caused by Uromyces viciae–fabae (Pers.) J. Schrot is considered as one of the most important diseases of field pea. It is responsible for substantial losses in terms of both quality and quantity parameters of grain. This reinforces the need to exploit several management strategies including chemical control. Therefore, present investigation was carried out to examine the efficacy of total of sixteen chemicals fungicides alone and/or in combination against rust disease of pea during 2012-2013 and 2013-2014. The results of the study revealed that all the sixteen fungicides were found effective for the management of disease as compare to control (water spray). However tebuconazole, carbendazim + tebuconazole, Mancozeb + tebuconazole, carbendazim + flusilazole, penflufen + trifloxystrobin were found equally and very effective among all. These fungicides showed considerable reduction in rust severity (12.50-16.67%) and area under disease progress curve (AUDPC) value (195.83-291.67) with high total yield (86.72-76.30 kg/ha) and test weight (160.94-180.93 g) as compare to control which showed highest rust severity (54.17%) and AUDPC value (1058.33) with lowest total yield (405.30 kg/ha) and test weight (144.0g). Correlation of AUDPC values with test weight and total yield were found significantly negatively correlated whereas no correlation was found with apparent rate of infection.
