Effectiveness of plant extracts for repressing stem rust disease severity of wheat caused by Puccinia triticina Eriks under field conditions

Abstract Background Stem rust caused by Puccinia triticina Erikss is one of the most devastating fungal foliar diseases, and causes substantial yield losses to wheat crops cultivated under field conditions. This study aimed evaluate efficacy plant extract-based sprays for with carnation, ginger cinnamon on severity stem infection three cultivars conditions two consecutive winter seasons (2020/21 2021/22). Results In both our data showed that all treatments were associated some degree disease suppression recorded as a range 2.3–8.6% compared 15.3–24.5% in untreated control treatment. The extract treatment was more effective than Amistar, commercial fungicide. They as: scores ranged between 2.3 3.2%; 3.0–4.5%, 3.0–6% cvs . Giza 1, Misr 2, Sids 14, respective order. Meanwhile, 4.1, 7.5, 8.6% at fungicidal Spaying plants carnation lowest prevalence followed extract, respectively. Increased grain reduced severity. Conclusions present investigation demonstrated using extracts against diseases it suggested they may be an alternative traditional chemical
