Abstract
Rust is one of the most widespread and devastating disease of cereal crop all over the world. This study was conducted to evaluate the efficacy of different fungicide against strip rust of wheat (Puccinia striiformis) at Toke Kutaye District, West Showa Zone of Oromia region, Ethiopia. The experiment was laid out in Randomized Complete Block Design (RCBD) in three replications and contains five treatments. Disease parameters like incidence, severity, Area under Disease Progress curve (AUDPC), and yield loss (dry biomass, grain yield, and thousands grain weight) were used to evaluate the treatments. The fungicides showed significant differences (P<0.05) in reducing incidence, severity, AUDPC and yield losses compared to the control treatment. There also significant differences between Zantara EC 216 and Rex®Duo fungicide in reducing disease incidence and also between Zantara EC 216 and Tilt 250 EC in reducing the disease severity. Zantara EC 216 fungicide reduced strip rust severity by 94.2% compared to the control treatment. The analysis of variance also revealed significant difference among Zantara EC 216 and Rex®Duo, Tilt 250 EC and Progress fungicides in reducing grain yield loss and thousand grain weights loss. Zantara EC 216 fungicide increased grain yield by 32.2% compared to the control. However, for the most parameters, there was no significant difference among Rex®Duo, Tilt 250 EC and Progress fungicides. Hence, Zantara EC 216 which is newly introduced to Ethiopian country was very effective and can be recommended as alternative fungicide for the management of strip rust of wheat in west showa zone of Ethiopia and areas of similar agro-ecological conditions.Keywords: Fungicides efficacy, Wheat, Severity, Zantara EC 216
Highlights
Wheat is one of the most important cereal crop produced worldwide (Curtis et al, 2002) and thought that it is the first crop ever to be cultivated and playing a major role in human’s economic and social development worldwide (Thabet and Najeeb, 2017)
The result of the analysis revealed that significant (p < 0.05) difference among treatments in reducing yield losses due to strip rust of wheat (Table 3)
This result was in agreement with the study conducted by Sharma et al (2016) on reduction of wheat yield losses caused by stripe rust, in which up to 39 % yield increment was obtained by different fungicides compared to unsprayed plot
Summary
Wheat is one of the most important cereal crop produced worldwide (Curtis et al, 2002) and thought that it is the first crop ever to be cultivated and playing a major role in human’s economic and social development worldwide (Thabet and Najeeb, 2017). It is the major cereal crop which playing a significant role in feeding a hungry world and improving global food security (Ketema and Kassa, 2016). The objective of this study was to assess the effectivity of different fungicides including the newly introduced product (Zantara EC 216) to control strip rust of wheat at west showa zone of Oromia region on susceptible variety
