IPM Control Strategies for Potato Late Blight: Reducing Fungicide Use by 45–100%
Field demonstrations in Scotland, France, and Poland showed that integrating resistant potato cultivars with hygiene measures and a decision support system cut fungicide use for late blight control by 45–100%.

Descrizione dettagliata
In 2025, three field demonstrations of an integrated late blight control strategy were conducted in Invergowrie (Scotland), Ploudaniel (France), and Bobrowniki (Poland). The strategy combined use of multiple resistant potato cultivars, sanitation practices, soil and crop management, and the Farmmaps BlightApp decision support system to optimize spray timing. Cultivars with higher resistance allowed delayed and fewer fungicide applications, resulting in reductions of 45% in France, 38–92% in Poland, and 92–100% in Scotland. Climatic conditions greatly influenced these outcomes, with dry weather enabling near-total fungicide elimination. This IPM approach enhances cost efficiency, sustainability, and aligns with goals to reduce chemical reliance.
