Late blight of potato which is caused by Phytophthora infestans, (Mont) de Bary is an important disease of potatoes (Solanum tubersolum) and is a prevalent disease in all potato producing areas of Ethiopia. A field experiment was conducted for two consecutive years (2016 and 2017) under the main rainy season to develop integrated management options for late blight disease of potato at Bursa District, Sidama Zone, SNNPRS, Ethiopia. Two improved varieties having different level of resistance, four registered fungicides, and two unsprayed plots (control) were arranged in a factorial randomized complete block design with three replications. The result showed that all fungicides significantly reduced the infection of late blight as compared to the unsprayed treatments at both seasons. Two way interaction of variety by fungicide showed significant difference on controlling.. View More»
