摘要

Potato late blight caused by the pathogen Phytophthora infestans is a widespread and devastating disease of potatoes worldwide which also affects the productivity of the crop in major potato-growing areas of Ethiopia. Farmers’ knowledge and perception of the disease and management practices are critical to effectively manage potato late blight. A survey of 120 randomly selected farmers was carried out in three major potato-growing districts (Dandi, Jeldu and Wolmera) during 2021/22 in Ethiopia’s central highlands. The objectives of the present study were to assess farmers’ knowledge on late blight management practices, as well as to identify potential interventions for the development of an integrated management of the disease through the IDM(integrated disease management) program. All quantitative and qualitative data were collected and analyzed using SPSS software Version 22. The analysis of results from the present study revealed that most of the farmers (79%) were able to identify foliar symptoms of late blight, but there was a clear lack of understanding of stem and tuber symptoms. The analysis of the qualitative data also showed that farmers had a very limited understanding of the disease, including its causative agent, spreading mechanisms, and effective management methods. The majority of the farmers (54%) associated potato late blight with climatic factors such as temperature, relative humidity, and rainfall. The survey results also showed that the majority of the farmers (98%) totally relied on fungicide application, primarily Ridomil and Mancozeb, as effective management methods. Therefore, it is suggested that integrating farmers’ knowledge with proper fungicides can be used to effectively manage potato late blight in the study area and with similar agro -ecologies in the country. The information generated from this study can be used by extension agents to train the farmers, and policy makers should give the highest priority in tackling this notorious disease of potato and enhance the productivity of the crop in Ethiopia.
