Effects of WABE 300 EC Fungicide against Stem rust (Puccinia graminis f.sp.tritici) and Yellow rust (Puccinia striiformis f.sp.tritici) of Wheat (Triticum aestivum)

Ethiopia is the largest producer of wheat (Triticum aestivum L.) in the sub-Saharan Africa. Despite its importance as food and industrial crop, wheat production and productivity around the globe is hampered by a number of factors including biotic and a biotic stresses as well as low adoption of new agricultural technologies. Of the biotic stresses, diseases caused by fungi are the most important factors constraining wheat production. Among the diseases stem rust and yellow rust, are highly destructive diseases of wheat worldwide. The recurrent occurrence of yellow rust and stem rust, diseases in the study area causes considerable yield losses. To prevent the yield loss due to these diseases, farmers used different fungicides released for either wheat diseases or other crop diseases alone or in a combination of fungicides with each other due to the disease's aggressiveness under field conditions. Field experiment was conducted to verify the effectiveness of the Wabe300 EC fungicide (Tebuconazole 225g/L + Triadimenol 75g/L) relative to another promising standard fungicide, Royal 750 WDG, for the management of stem rust and yellow rust of wheat. The experiment was conducted at Kokate, Dalibo Wogane and Zala Shasha, on farmers’ field in a Randomized Complete Block Design (RCBD) with five replications during 2023 cropping season. The experiment result confirmed that, fungicide treated plots were showed significant difference compared to the control treatments in all variables. Wabe 300 EC foliar application at the rate of 0.5 L/ha with 200 liter water per hectare was highly effective in controlling yellow and stem rust of wheat and increased grain yield of wheat. Hence, it is recommended for registration for the management of stem and yellow rust in wheat production. During the growing periods, no foliar toxic effect was observed from the effect of any tested fungicides.
