Abstract: In the present study, some fungicides were tested for their ability to inhabit or cidal effect against a plant pathogen Fusarium oxysporum f. sp. pisi causes wilt disease of Pea (Pisum sativum L.) cultivated during the cool season in subtropical and temperate countries. The experiment was carried out by poisoned food technique in which different doses of fungicides were mixed in Potato Dextrose Medium (PDA) and growth inhibition of fungal pathogen was observed. The fungicides tested were Carbendazim 50% WP, Tebuconazole 10% + Sulphur 65% WG, Propineb 70% WP, Metiram 70% WG at four different concentrations (25ppm, 50ppm, 100ppm and 200ppm). The treatments were arranged in completely Randomized Design was followed (CRD) with three replications of each treatment and plate having no treatments served as control. Growth was observed after 3 days, 6 days and 9 days intervals after the inoculation. Maximum inhibition of growth of F. oxysporum f.sp. pisi was reported with the all doses used of fungicide combination of Tebuconazole10% + Sulphur 65%WG and then followed by higher dose (200ppm) of Carbendazim 50%WP. The fungicides Propined 70%WP and Metiram70%WG were found very less effective against fungal pathogen. The higher concentration these two fungicides (200ppm) used, inhibit 33.33% and 25.25.19%, respectively. The study revealed that combination of Tebuconazole 10% + Sulphur 65%WG can be explored to control the wilt disease of pea crops in the field.
