Taro leaf blight has had a profound economic impact on Cameroonian farmers, as it significantly reduces taro yields and disrupts local economies. The outbreak of taro leaf blight in Cameroon between 2005 and 2010 caused an estimated economic loss of over 70 billion FCFA, leading to severe food insecurity and escalating prices of taro and related products (Tarla et al., 2017). The disease, caused by the pathogen Phytophthora colocasiae, affects both the quantity and quality of taro production, resulting in low yields, poor quality corms, and reduced commercialization. Farmers incur increased costs due to the need for fungicide applications and other disease management practices. For instance, economic analyses have shown that fungicide treatments can increase yields by up to 74% for certain taro cultivars, with net benefits reaching 8.26 million FCFA per hectare for intensive management practices (Tarla et al., 2014). However, these treatments also entail significant costs, reducing the net economic benefit for farmers. The disease has also impacted post-harvest processes, with rapid biodeterioration of corms further affecting marketability and price stability. While breeding for disease-resistant taro varieties has shown promise, the spread of the disease to new regions continues to threaten livelihoods and food security in Cameroon (Mbong et al., 2013). Thus, the economic burden of taro leaf blight underscores the need for effective disease management strategies and the development of resilient taro cultivars to sustain production and stabilize local economies.
