Abstract

Wheat is one of Ethiopia’s foremost important cereal crops in terms of area coverage and volume produced. However, the production and productivity of wheat is constrained by various biotic and a biotic stress. Among biotic stresses, wheat stem rust disease caused by Puccinia graminis f. sp. tritici is the most catastrophic disease. Field experiments were conducted to verify and evaluate the efficacy of new fungicide against wheat stem rust at Debrezeit and Negelle Arsi locations in 2021/2022 main cropping season. For comparison, treatments included one candidate fungicide (Cona), Rex Duo as a standard check, and Unsprayed (control) applied towards the durum wheat variety Alemtena. The experiment was designed with a randomized complete block design and three replications. Terminal rust severity levels of up to 20MS, 15MS, and 60S at Debrezeit and 15MS, 20MS and 50S at Arsi Negelle were recorded on the tested fungicide CONA, Rex Duo and unsprayed or control treatments, respectively. Fungicide-sprayed treatments was significantly reduced the severity of stem rust to the lowest level possible when compared to nil (unsprayed) application. However, there was no statistically significant difference (P<0.05) in reducing the severity of stem rust disease between the test and standard check fungicides. When compared to the standard check, the test fungicides demonstrated comparable and better efficacy in reducing the severity of stem rust. The difference in biomass yield, grain yield, and thousand kernel weight between fungicide treatments and no fungicide application were highly significant (P<0.05). The highest grain yield was obtained from CONA sprayed plots at Negelle Arsi, while the lowest yield was obtained from nil application. At both locations, fungicide treatments outperformed untreated plots in terms of disease severity, yield and yield components. The newly verified fungicide has been found to be very effective in controlling wheat stem rust, and is recommended for registration to control wheat stem rust.
