Abstract: 
Faba bean gall becomes the worst problem for the crop production. The diseases can cause up to complete crop failure. Studies showed that, applications of some fungicides and seed dressings have certain effects of reducing faba bean gall diseases and increases yield. Thus, the study aims to select best effective and economical fungicide for faba bean gall disease management. The experiment was conducted at farmers’ field on hot spot areas to manage the disease using fungicides in 2019/20 cropping season. Randomized complete block design with three replications was used. Nativo SC 300, Eminant star, Rex-Dou and Mancozeb 80 WP fungicides were applied as manufacturers’ recommendations. Significant difference between plots in plant height, disease severity, area under disease progress curve, grain yield and thousand kernel weights were recorded. The highest (46.67%) disease score were recorded in control plots followed by Rex-Dou (40.0%) sprayed plots. Whereas the lowest, disease severity (15.11%) were recorded from Eminant star sprayed plots. The highest grain yield was recorded in Eminant star (3.08 ton ha-1) sprayed plot followed by Nativo Sc 300 (3.01 ton ha-1) and Mancozeb 80 WP (2.54 ton ha-1) sprayed plots respectively. Eminant star sprayed plots also gave the highest economic benefit ETB (102770.0) and marginal rate of return (1678.46) followed by Nativo Sc 300 with net benefit of ETB (99190.0) and a marginal rate of return (925.40) were received. Pod per plant was not showed significant difference between plots.
