Drones, DNA, and weather: A phase-oriented hybrid engine predicts sugar beet disease

Phys · · 437 words · By American Phytopathological Society

A study published in Phytopathology describes a new method using drone imagery, weather data, and molecular diagnostics to predict sugar beet disease outbreaks. The approach integrates mechanistic models and machine learning to track the life cycle of Cercospora beticola, improving disease forecasting accuracy by up to 39%.
