Fungicidal management of field Pea (Pisum sativam L.) Powdery Mildew (Erysiphe polygoni DC) Disease

Abstract

Ethiopians produce peas primarily to prepare their traditional dish called shiro. It is not wrong to say that most Ethiopians eat enjera with shiro wot once a day or a three day. Therefore, recognizing the importance of the crop, farmers in Koga Irrigation scheme have started producing peas, but have constraint to grow crops due to the powdery mildew disease. Therefore the experiment was conducted to evaluate and recommend effective fungicides against powdery mildew of field pea. The experiments were conducted during 2019 G. C cropping season through irrigation by using completely randomized block design (RCBD). The result of the experiment shows that, spraying of tebuconazole, propiconazole and Triadimefon can reduce the disease in to 81%, 77.6% and 68.2%, respectively compared to untreated control. Correspondingly, spraying of thus fungicide increase seed yield by 33.5%, 29.6% and 28.8%, respectively, as compared to the untreated control. Therefore, the application of tebuconazole, propiconazole and triadimefon is recommended for the management of powdery mildew on field pea crop.
