A portable decision support tool cuts fungicide use in Kenya, keeping potato harvests and environmental health high

Late blight presents a double-edged challenge for potato farmers in Sub-Saharan Africa: not only does it cause significant yield losses and production costs but it also poses health and environmental risks. Picture this: in peak rainy seasons, farmers in Kenya, a typical scenario in Sub-Saharan Africa, spray fungicides as frequently as 14 times a season-essentially 2-3 times a week. Now, think about the labor, time and financial burden, and the chemicals seeping into the environment, potentially affecting animal, aquatic and human health.
