Effects of Fungicides and Cultivar Resistances on Fusarium Head Blight Management and Durum Wheat Yield Related Parameters in Debre Zeit, Ethiopia

Fusarium head blight is a threat to durum wheat production in Ethiopia, its direct detrimental effects on yield and quality. objective of this subject, to enhance quality seed production, a field experiment conducted at Debre Zeit Agricultural Research Center, Ethiopia during the 2022/2023. The experiment included three fungicide treatments (control without spraying, Propiconazole, and Tebuconazole) and six durum wheat varieties (Alem-Tena, Utuba, Mangudo, Et cross-21, Ude, and Tesfaye), organized using a randomized complete block design with three replications. Data were collected and analyzed using analysis of variance (ANOVA) in SAS. Mean comparisons were conducted at the 5% significance level using Tukey’s test. The results showed that the highest grain yield (4.63 t/ha) was recorded for the variety Et cross-21 treated with Tebuconazole, while the lowest yield (2.29 t/ha) was observed for Alem-Tena under the unsprayed control condition. Maximum and minimum net benefit (240314, 120467) Ethiopian birr obtained from Et cross-21 treated with Tebuconazole and control(unsprayed) variety Alem- Tena respectively. Therefore, integrated management was best management option for Fusarium Head Blight and could be recommended for durum wheat producers’ farmers.
