Abstract

Coffee berry disease (CBD), caused by Colletotrichum kahawae, is a major fungal disease of coffee in east Africa, and particularly in Ethiopia. To assess the influence of plot features (elevation and slope) and landscape structure (land use types) on the epidemics of CBD, a study was conducted in 2012 and 2013 in 30 smallholders’ coffee plots in southwest Ethiopia. Elevation was the most determining plot feature that influenced the incidence of CBD and berry drops. North-facing coffee plots were affected more by CBD compared to south-facing plots. Landscape structure generally had weak relationship with CBD incidence and berry drops. Overall, coffee growers should give more attention to plot features than landscape structure for CBD management.

摘要

由卡哈瓦炭疽菌引起的咖啡浆果病 (CBD)是东非，尤其是埃塞俄比亚的主要咖啡真菌病害。为了评估地块特征（海拔和坡度）和景观结构（土地利用类型）对 CBD 流行的影响，2012 年和 2013 年在埃塞俄比亚西南部的 30 个小农咖啡地块中进行了一项研究。海拔是影响 CBD 和浆果掉落发生率的最具决定性的情节特征。与朝南的地块相比，朝北的咖啡地块受 CBD 的影响更大。景观结构与CBD发病率和浆果下降的关系普遍较弱。总的来说，咖啡种植者应该更多地关注地块特征而不是 CBD 管理的景观结构。
