| dc.description.abstract | Faba bean (Vicia faba L.) is one of the major pulse crop grown in the highlands of Ethiopia but it yield has been reduces due chocolate spot disease infestation. This study was conducted at dabat district in 2020 cropping season with the objective assessing the economic importance of chocolate spot disease and determine the integration management of faba bean chocolate spot disease by using fababean varieties and fungicide application schedule. Survey was conducted in the five major faba bean producing kebele of Dabat districts, North Gondar Zone a. A total of 385 faba bean farmer fields were assessed for the incidence and severity of chocolate spot disease. Farmer fields were assessed and the collected data were analyzed by using SPSS version 20. Field experiment was arranged in randomly complete block design in 4x4 factorial combinations with three replications. The treatments include four faba bean varieties( Local ,Walki, Dosha and Tumsa) and four fungicide application schedule(un spray,7 day spray, 14 day spray and 21 day spray) of Mancozeb 80% WP at 2.5kg/ha . The disease, yield and yield related data were subjected to analysis of variance using the general linear model procedure of SAS 9.2. The surveyed kebele most of the farmer sows local variety and does not use fungicide in this case chocolate spot disease was high in all assessed field. Relatively high mean incidence (98.27%) and severity (73.05%) was recorded at Abtera kebele and low disease incidence (91.79%) and severity (62.27%) was recorded at Chila kebele. The interaction of variety with fungicide application schedule had significant (p<0.05) effect on chocolate spot disease. The minimum disease severity (14.5%) recorded from walki variety with 7 day spray interval of Mancozeb 80 % WP fungicide application while the maximum disease severity (59.5%) was recorded from unsprayed local variety and the lowest disease incidence (52.66 %)was recorded on walkie variety with 7 day fungicide spray interval.while the highest disease incidence (95%) was recoreded from unsprayed local variety in the final disease assessment. The highest AUDPC (1547.8%-day) was recorded from unsprayed local variety while the lowest AUDPC (574.2%-day) was recorded from walki variety with 7 day spray interval of mancozeb 80%WP fungicide. In this study Walki faba bean variety with fungicide treatment particularly with weekly Mancozeb fungicide application schedule had provided best result in terms of chocolate spot disease management and get benefit from yield production. Since the research was conducted for one year the experiment should be repeated. | en_US |
