Abstract

The experiment was conducted in Semen Ari district to demonstrate fungicides against wheat strip rust and fusarium head blight (FHB) diseases during 2018 and 2019Rex®Duo and Tilt (propiconazole) fungicides were applied to the variety Danda'a. There were three therapies employed, including no therapy. A single plot design contained all of the treatments. Fungicides showed greater efficiency against both illnesses than the unsprayed plot. In 2018, the percentage severity index for yellow/strip rust from the Tilt250EC, Rex®Duo, and control plots was recorded as 59.84%, 41.26%, and 100%, respectively. In 2019, the percentage severity index decreased to 38.33%, 26.26%, and 70% from Tilt, Rex®Duo, and control, respectively. The Percentage Severity Index of FHB was recorded as (41.5%, 46.6% and 62.8%) in Rex® Duo, Tilt250EC and untreated control plots in 2019 respectively In the 2018 and 2019 growing seasons, Rex® Duo reduced wheat yellow rust disease by 63% and 92 %, and tilted by 39% and 68 % compared to the untreated plot. By the years 2018 and 2019, the yield in the Rex® Duo treated plot enhanced by 69.67% and 39.14%, and in the Tilt treated plot by 67.43% and 31.03% compared to the control plot. Farmers liked Tilt as their second choice after Rex® Duo. The fungicide Rex® Duo had the largest net benefit, followed by Tilt, according to the cost-benefit analysis. Both fungicides effectively prevented the diseases.. Therefore, it is better to use Rex® Duo followed by Tilt 250EC* to control both diseases and improve wheat productivity.
