UAV-based Spot Spraying Against Plant Diseases UAV-based Spot Spraying Against Plant Diseases

Plant diseases often exhibit a patchy distribution within fields. The application of fungicides, however, is often based on environmental conditions and visual assessment and then, in practice, is homogeneous over entire fields. A site-specific control of plant diseases with robotics and drone technology provides the potential to improve the efficacy of disease control while reducing the negative impact on agricultural ecosystems.
